Kathie's Story:
Misdiagnosed with Lung Cancer
In July 2002, my wife Kathie was misdiagnosed with lung
cancer in an American Cancer Society-sanctioned clinical trial. A few weeks
later, she underwent an unnecessary $40,000 surgery from which she will likely
never recover in full.
Many others could find themselves in a similar
position. The U.S. government's National Cancer Institute is currently
conducting a clinical trial with 50,000 subjects, 25,000 of whom are getting
computerized tomography (CT) scans to screen them for possible lung cancers.
Some will probably, like Kathie, be misdiagnosed. In addition to that, CT scans
are now being increasingly given at annual physicals to screen people most at
risk of developing lung cancer.
I have written this article in the hope that I
can help people better understand CT and PET screening technology, permitting
them to make intelligent, informed decisions while avoiding unnecessary pain and
suffering. By discussing cautions that individuals may wish to consider if they
are screened for lung cancer using low-dose helical computerized tomography
(CAT) scans and positron emission tomography (PET) technology, I will hopefully
help patients not familiar with these technologies better understand how they
can go wrong. You're going to learn things here that your doctor, your surgeon
or your radiologist might never tell you.
Prior to beginning publication of this
article, I sent an email to people prominently mentioned in the article asking
if they would be interested in an advance copy to read for accuracy. One person
responding was Dr. Michael V. Smith of Atlanta, who is mentioned prominently. He
said in an email to me of the title, "I fear that while it makes good copy this
description will frighten the uninformed and provide unsubstantiated ammunition
to those opponents of early detection of lung cancer."
It is not my intent to frighten. I hope that
those who read the entire article will realize that my intent is to to inform,
and that the title is an accurate description.
The story begins when I first became
interested in lung cancer while teaching public relations classes at the
Universities of Wisconsin and Georgia. Reading about the history of public
relations, I learned of the role played by advertising and publicity in
promoting cigarette smoking, and of the persuasion effort needed to discourage
people from smoking.
This interest led me to ten years of service
on the board of directors of the Georgia chapter of the American Lung
Association.
After that, I served with the American Cancer
Society in a number of capacities, including stints on the board of directors
and the executive committee of the Georgia Unit and Southeast Divisions, and in
a number of committee assignments.
Note that my areas of expertise are journalism
and public relations. I'm not a doctor, and don't pretend to know what doctors
know. I do know how to write, and have written 11 books on various subjects.
2. Meeting Dr. Smith
In the late 1990s, or perhaps 2000 or 2001,
one of the American Cancer Society committees on which I served was preparing
recommendations for the position the American Cancer Society should take in
lobbying the Georgia Legislature regarding a monetary windfall coming to the
state as a result of the master settlement with the tobacco industry. The state
expected to receive in the neighborhood of $200 million per year for 25 years. A
number of community leaders, including Hamilton Jordan, former chief of staff
for President Jimmy Carter and a three-time cancer survivor, wanted part of that
money to go to improving Georgia's cancer infrastructure.
The upshot was that then-Gov. Roy G. Barnes in
2001 launched the Georgia Cancer Coalition, which was to be a 10-year, $1
billion initiative to build a major cancer research and treatment presence in
the state. Some $400 million in tobacco settlement funds and $600 million in
federal and private money were to fund the initiative.
At one of the morning meetings of the group, a
young Atlanta surgeon and graduate of the Medical College of Georgia, Dr.
Michael V. Smith, MD, FACC, FACS, FCCP, came in to talk about a clinical trial
he hoped to conduct at Atlanta Medical Center, formerly the respected Georgia
Baptist Hospital, which Tenet had bought and renamed.
Tenet, a publicly owned corporation that
operates health care facilities in a number of states, is the parent corporation
that was involved in a number of unnecessary surgery cases in California.
Dr. Smith had become familiar with the
pioneering work of radiologist Dr. Claudia I. Henschke of the Weill Medical
School of Cornell University in New York. She had for a number of years been
using CT scans as a way to screen for lung cancer tumors in high-risk patients.
Dr. Henschke pioneered in finding lung cancers
in the people most likely to get them much earlier than they can be detected by
conventional X-rays. Conventional X-rays don't detect lung tumors until they're
about 30 mm. (the size of a quarter) or larger. CT scans can find them when
they're no bigger than a grain of rice, a sixth of the size detectable by
conventional X-rays.
CT scans, like X-rays, rely on gamma
radiation. Instead of a single picture like that taken by an X-ray machine,
however, a CT machine takes many pictures as targets on a large hollow wheel
whirl around the patient. The patient is examined in a series of thin slices,
much as a loaf of bread might be sliced. In a chest scan, lung tissue appears
black on the film produced by the machine. Blood vessels appear white. The
radiologist reading the images or film looks for white spots that are not blood
vessels. Those are suspect tumors. Computers assist in the recording and
analysis of the images.
Early detection of cancer is important to
treatment. If tumors can be detected before they've metastasized or relocated to
other parts of the body, the job of treating them with techniques such as
surgery, chemotherapy and radiology is much more likely to be successful.
Success in cancer treatment is measured by five-year survival—whether or not a
patient is still alive five years after diagnosis.
Most lung cancers are detected late, resulting
in only 14 percent or so of all patients surviving for five or more years. Most
die within a year of detection. But if lung cancers are detected early,
five-year survival rates improve to 42 percent on up.
In 1992, Dr. Henschke and her colleagues at
Weill launched the Early Lung Cancer Action Project (ELCAP). Over six years,
they recruited 1,000 high-risk volunteers—people over 60 with an extensive
history of present or former smoking—who were given CT scans plus chest X-rays.
Only four of the high-risk subjects turned out to have lung cancers detectable
by X-ray, but CT scans uncovered tumors in 27 of the subjects, including 23
tumors at the earliest stage of development.
Dr. Henschke by 1998 had shown that CT scans
can an effective screening tool for lung cancer. Dr. Smith wanted to take her
work a step further.
One of the problems with CT scans as a
screening tool is that almost half the high-risk population has fibrous masses
in the lungs resembling cancer tumors.
Most of these masses are benign, often dating
back to childhood when a foreign substance was inhaled and the lungs took
protective action by encasing the harmful substance in a fibrous mass. So how do
you distinguish the very few of these fibrous bundles that are cancers from
those that are not?
Dr. Smith believed the answer was a new
technology called positron emission tomography or PET scanning for short. Here's
how it works. The patient is injected with a radioactive substance in a glucose
(sugar) solution. Cancer cells are hungry for energy and absorb 20 times as much
of the radioactive glucose as normal cells. Targets whirling around the patient
in the same way a CT scanner works pick up the radiation being emitted by the
radioactive solution.
Exactly how the PET scanner works is
complicated, involving the annihilation of positrons and electrons with
resulting vectored gamma radiation. Let's just say that if a lot of radiation is
picked up by the PET scanner in the same area as a suspected tumor identified on
earlier CT scans, then there's a fair probability that the fibrous mass showing
up "hot" (emitting a lot of radiation) on the PET film is a cancer.
Dr. Smith says he became interested in
developing a better method of screening for lung cancer after his mother died of
the disease. Having a parent die of lung cancer that was not diagnosed early is
a powerful motivator. I know that, because both my mother and father died of
lung cancer.
When Dr. Smith became interested in using PET
scanning as a screening tool, the technology was a relatively new tool, although
it already had a track record in cancer diagnosis. Doctors at oncology (cancer
treatment) centers were already using PET scanners to stage and track the
progress of cancers that had been diagnosed in patients. The scanners were
helpful in telling if treatment was successful (the cancer was shrinking) or, if
instead, the cancer was growing.
I don't recall that Dr. Smith said all this in
the ACS meeting where he spoke of his proposed clinical trial, but he said
enough to favorably impress the committee on which I served. The upshot was that
the Southeast Branch of the American Cancer Society eventually approved Dr.
Smith's research plans.
3. Kathie learns of the clinical
trial
I forgot all about that morning meeting until
many months later, when my wife Kathleen heard a promotional spot on television
about Dr. Smith's clinical trial. She wanted us to participate. She persuaded me
to go with her to Atlanta Medical Center, where we enrolled on June 19, 2002.
The person who registered us, Beatrice Saba,
was a personable young lady visiting Georgia from Africa. She told us of the
Tenet doctors who would be involved in the trial. One was Dr. Louis Lovett.
Another was Dr. A. Hamblin Letton. Dr. Letton, a past president of the American
Cancer Society, is renowned for his role in encouraging women to conduct breast
self-examinations to detect cancer tumors. He once reportedly turned down an
offer from President Richard M. Nixon to serve as U.S. surgeon-general.
Beatrice also told us that Dr. Barry F.
Jeffries would be the radiologist who would be reading CT and PET scans
conducted during the clinical trial, the goal of which was to enroll 1,500
subjects over 55 who had at least a 20 pack-year history.
A pack-year consists of smoking a pack of
cigarettes a day for a year. Smoke one pack a day for a year—that's one
pack-year. Smoke two packs a day for a year—that's two pack years. Smoke half a
pack a day for a year—that's half a pack-year. My wife Kathie and I met the
criteria, although, like the 1.3 million Americans per year who quit smoking for
good, we had both quit many years earlier. We were, nonetheless, among the 90
million Americans who at one time or another had smoked.
Another thing we learned from Beatrice was
that PET scans would be given only to subjects who had suspect lung nodules on
their CT scans.
4. We attend the introductory
seminar
On June 26, Kathie and I attended a two-hour
"seminar" at Tenet's Atlanta Medical Center. The meeting was held in space
provided by Tenet to GILCR for the clinical trial. It was during this meeting
that I first realized Dr. Smith as the same physician who had talked of his
proposed research to the American Cancer Society committee on which I was
serving earlier.
At the meeting, we were told that Reynolds
Jennings, on behalf of Tenet, had donated $150,000 to jump-start the GILCR
screening trial. The goal of the trial, we were told, was to detect lung cancers
earlier, so that survival rates could be improved. As of that evening's meeting,
we learned, three cancers and three probables had been found using CT plus PET
technologies. Subjects for the trial had to be 50 years or older, with a 30
pack-year history. That was a little different from the 20 pack-year history
we'd heard from Ms. Saba, but the difference seemed unimportant.
At the June 26 meeting, Dr. Smith mentioned
his frustration over getting money he'd asked from the Georgia Legislature. The
Georgia Cancer Coalition (GCC) was now disbursing most of the money Georgia
planned to spend on lung cancer research
A major part of the money being channeled
through GCC, at the urging of Hamilton Jordan and other influentials, was being
allocated to fund what Georgia hoped would be a world-class cancer research
center at Emory University. Emory, which graduates of the rival Medical College
of Georgia sometimes say has an edifice complex, used much of the huge grant it
was receiving to build a building. But researchers were being hired and brought
in, and by mid-2004 Georgia had attracted 66 of the 150 cancer researchers it
hoped to recruit for the Emory research center. The researchers by mid-2004 had
brought $77 million in federal grants with them.
While Emory was benefiting from the state's
largesse, Dr. Smith's request for $1.5 million in funding had been cut in budget
hearings to $300,000, and he had not received a single penny of that. As it
would turn out, none of even the $300,000 would ever go to GILCR, which by July
2004 had closed down the lung cancer screening trial.
As part of his presentation at the June 26,
2002, meeting, Dr. Smith mentioned that Dr. Hadyn Williams of the Medical
College of Georgia was monitoring his research. Dr. Williams, he said, had
studied at Cornell, where Dr. Henschke was conducting her pioneering work with
computerized tomography to screen for lung cancer.
Among other comments, Dr. Smith said at the
meeting that PET scans were 90 percent accurate in determining whether or not
suspect fibroids in lungs were tumors. Later in the presentation, he stated that
PET scans were 95 percent accurate in identifying cancers.
As for scanning for tumors, Dr. Smith noted
that while conventional X-rays can find fibrous bundles if they are 30 mm. or
more in size, CT scans can find fibrous bundles down to 5 mm. in size. That's
the difference between finding something the size of a quarter versus something
the size of a pencil eraser, as he put it. The earlier a tumor is found and
treated, the greater the chances for successful treatment.
He indicated that the ideal subjects for
GILCR's Early Detection Initiative were individuals 55 or older, with a 30
pack-year or more history, who had stopped smoking no more than 10 years earlier
and had no prior cancer history.
Dr. Smith indicated that while GILCR study
subjects were experiencing no delays in getting CT scans, PET scans were a
different case. At the time, there were four fixed and three mobile PET scanners
in the Atlanta area. The GILCR study accessed one of the mobile scanners once
every two weeks. As of the July 26 2002 meeting, 50 subjects in the GILCR study
were waiting to get PET scans for suspect nodules identified by CT scans.
5. I write an article about Dr. Smith's need for funding for the
Atlanta Journal-Constitution
I was impressed with what we learned at the meeting about
what Dr. Smith had accomplished. I still believe that CT and PET scanning can
play an important role in lung cancer screening. At the time, of greater
reIevance to this narrative, I thought he deserved state funding for his
research.
Based on what I had learned at his seminar, I wrote an
opposite-editorial (op-ed) piece for the Atlanta Journal-Constitution,
Atlanta's daily newspaper. The piece, headlined "Broken promise limits cancer
research funding," appeared in the July 5 issue of the paper. It detailed the
results of Dr. Smith's research (at the time, three cancers found in 250
subjects screened), and recounted how he had been budgeted money by the Georgia
Cancer Coalition, but that the money had not been forthcoming.
6. I question radiation doses
Kathie and I followed separate paths for getting our
respective CT scans. As it turned out, because of what turned up in our lungs at
each test, we both got a CT scan, we both got a subsequent CT scan with contrast
(more powerful) and we ultimately each got a PET scan. Except for her PET scan,
which was done at a mobile unit at Northside Hospital in Atlanta, all of our
tests were done at Atlanta Medical Center in downtown Atlanta.
When I went for my CT scans, I made a point of asking about
radiation doses. I was surprised to learn that the Atlanta Medical Center
technicians were unable to answer my questions. They didn’t know what the
radiation doses were.
I didn’t find out until much later that CT scans expose a
subject to significantly larger doses of radiation than X-rays.
For those interested, One measure of radiation dosage is the
REM. A standard or conventional X-ray likely exposes the subject to 1/100th of a
REM (0.01 REM). A typical adult CT brain scan results in the patient absorbing
about six REMs, or 600 times as much radiation as an X-ray. A chest or abdominal
scan exposes the patient to two to three REMs, or 200 to 300 times the gamma
radiation of an X-ray.
More accurate estimates of radiation danger in the U.S. come
from the National Academy of Sciences (NAS). A panel of NAS researchers reports
every decade or so on radiation hazards. The panel issued one report in 1990,
and another more recently in 2005. In the latter, it concluded that even very
low doses of radiation—from X-rays, and from closely related gamma rays emitted
by nuclear materials used in medicine and some commercial products—pose a risk
of causing cancer over a person’s lifetime. The most recent report of the panel,
issued after five years of study, rejected the contention of some scientists
that tiny doses of radiation are harmless.
Most of us get more radiation naturally from the environment
than we do from medical testing. Activities such as eating, breathing and
drinking account for about 82 percent of the radiation to which we are exposed.
The remaining 18 percent of the radiation we get comes mostly from medical
radiation, but also from television and computer monitors. Tobacco smoke and
some building materials can also expose us to man-made radiation.
For its 2005 report, the NAS panel used the millisievert as
its unit of measurement. In the United States, the average person is exposed
annually to about three millisieverts of natural background radiation, mainly
from the sun. A chest X-ray exposes a patient to about 0.1 millisievert, while a
CT scan is about 10 millisieverts, a little more than three times natural annual
exposure and about 100 times the exposure from an X-ray.
The NAS panel estimated that one out of 100 people exposed to
100 millisieverts of radiation over a lifetime probably would develop solid
cancer or leukemia, and about half of those cancers would be fatal. An
additional 42 cancers might develop in the same group of 100 from other causes
such as genetics, workplace chemicals and environmental contaminants. That
places the risk of getting cancer from medical radiation low. Doctors and
radiologists argue with good reason that for patients at high risk of disease,
the radiation dose from a CT scan is less a risk than not detecting, diagnosing
or staging the disease.
The NAS scientists concluded, nonetheless, that medical
radiation is dangerous, and can, among other things, cause cancer. The risk is
greater for those who get a large number of tests involving radiation.
The use of medical radiation is on the rise. Where CT scans were once used
largely for diagnosis, they are now being used widely for screening as well as
for diagnostic purposes. About 45.4 million CT scans were performed in 2002
nationwide, up 14.6 percent from 39.6 million in 2001. The number of PET scans
performed in 2003 was up an estimated 58 percent in 2003 from 447,200 in 2002.
7. The mystery of the dread diagnosis
By July 9, Kathie had been given a CT scan plus a CT scan
with contrast at Atlanta Medical Center, plus a PET scan, the last provided at
Northside Hospital.
Kathie and I were covered by my medical insurance, so the
cost of our scans were paid by that.
We met with Dr. Smith at his office on July 9. She was told
then that she had three suspect nodules in her lungs. Of the three suspect
nodules, PET scans had eliminated two of the three as cancers, and had probably
eliminated the third, we were told. Kathie taped the conversation. I took some
digital photos of the films from her scans as Dr. Smith discussed them with us.
She and I went on to an appointment she had with her
pulmonologist at St. Joseph's Hospital.
Three days later, on Friday, July 12, Dr. Smith called. He
had bad news regarding that third suspect nodule in the right hilum area of her
lungs. He now believed the third abnormality in her lungs was a cancer requiring
surgery.
Someone had determined that this nodule was malignant. Dr.
Smith did not tell us who had made that diagnosis, only that it had been made by
"the best radiologist he knew."
I doubted at the time that Atlanta Medical Center radiologist
Dr. Jeffries, who was voluntarily reading the GILCR CT scans for those without
insurance, was the one. He had earlier complained about the quality of Kathie's
CT scans which we had discussed with Dr. Smith on July 9. If he had diagnosed
the suspect masses as cancers, or even suspected that they were cancers, we
likely would have heard about it on July 9, not three days later, on July 12.
After reviewing my notes and Kathie's tapes, I decided Dr.
Smith must have asked someone else to look at her films.
Who had made the determination of malignancy? Was it Dr.
Henschke of the ELCAP studies at Cornell's Weill Medical Center? Dr. Smith had
mentioned that film from his study was being reviewed by the participating ELCAP
people at Cornell. Could it have been Dr. Hadyn Williams of Dr. Smith's alma
mater, the Medical College of Georgia? Dr. Smith and others had indicated that
Dr. Williams, who had studied at Cornell before moving to Georgia, was involved
in the GILCR study.
As of this writing, I don't know who changed the earlier
diagnosis. We'd both really like to know. I think Kathie has a right to know.
She's the one who underwent unnecessary surgery as a result.
From July 12 on, things began to progress rapidly, pretty
much out of our control. We were at the mercy of medical professionals who knew
a lot more than we did.
8.
Kathie's story: Even radiologists get it wrong when reading CT and PET scans
On July 16, while we were waiting for a test procedure to be
performed on Kathie, we both read an article by David Wahlberg in the Atlanta
Journal-Constitution about body scans for cancer that gave us pause.
Headlined "Inside Story," it argued that CT scans for hidden diseases can save
lives, but that many physicians felt drawbacks of the scans outweighed their
worth. The article pointed out that a spot in a lung, kidney or liver that shows
up on a CT scan could be a cancer, but was more likely to be a harmless tumor or
a scar from an infection.
A related story in the same paper detailed the experiences of
Dr. William Casarella, head of the radiology department at Emory University's
Medical College in Atlanta. Dr. Casarella, who is in charge of overseeing the
reading of CT scans at Emory Hospitals, had undergone a screening CT scan that
turned up suspicious masses in his left kidney, his liver and his lungs. As a
result of these suspicious spots, he had subjected himself to a number of
painful, probably unnecessary procedures and surgeries.
I did not realize until I reread Dr. Casarella's story two
years later that it had contained a warning Kathie and I might have heeded if
our doctor had explained the significance.
Among the things that had turned up on Dr. Casarella's
full-body CT scan, in his own words, were seven or eight spots on his lungs. To
get more information, he had undergone a second, more detailed CT scan of both
lungs, which was inconclusive. "After that," he wrote, "we did a PET scan to see
if the lesions were active in taking up glucose, which would mean they are
cancerous. There was no uptake, but the lesions were at the limits of resolution
for current PET scans, so it wasn't really that helpful." Dr. Casarella went on
to explain that he could have followed the fibroids with periodic CT scans to see
if they grew, which would indicate malignancy. But he decided instead to have
the lung lesions biopsied surgically.
Before the operation, he had blood tests, a pulmonary
function test and a cardiac stress test. Then, during the surgery, he said,
"they made a 6-inch incision on the side between the ribs. They deflated my
lungs so the surgeons could feel it and find the nodules. They cut out three
lesions, which showed I had histoplasmosis, a benign fungus infection that had
healed itself. Millions of people have this and never know it." His bill for the
needless surgery and hospital stay was $47,000
It would turn out that Kathie would be one of those millions of people who
underwent a similar needless surgery, and she was being rushed toward it at a
relentless speed. We were, unfortunately for Kathie, too naive to ask that
if even expert radiologists were being confused by CT and body scans, what were
our odds?
9. The bronchoscopy
We'd asked Kathie's pulmonologist to perform a bronchoscopy
in the hope that it would confirm or eliminate the need for surgery on Kathie's
suspect cancer. In a bronchoscopy, a thin tube containing fiber-optic strands is
inserted into the bronchus of the patient's lungs. The doctor can use the
instrument to examine the larger passages of the lungs. If a cancer was indeed
growing in the right hilum area of Kathie's lungs, it was possible the cancer's
presence could be seen by the doctor through the bronchoscope.
The bronchoscopy was performed on July 16. The doctor played
back the images for me after the procedure. No cancer was detected. That didn't
mean there wasn't one—just that it was not detected by examination of the
bronchus with a bronchoscope.
Dr. Smith felt the bronchoscopy left surgery as the only
viable way to confirm the cancer and begin treating it.
Kathie's pulmonologist disagreed. He thought it would be more
prudent to wait for three months or so for another CT scan to see if the suspect
mass had grown, eliminating the need for surgery to prove that the suspect mass
was a cancer.
I'd been reading what I could to update myself about cancer
and treatment in the free time I had in these days. Kathie and I asked Dr. Smith
if it wasn't more practical to get a tissue sample for biopsy using fine needle
aspiration rather than radical thoracic surgery. Dr. Smith warned against that,
cautioning that the needle used could drag cancer cells with it as it was
withdrawn, spreading cancer cells behind it.
10. Putting together a treatment team
We'd gotten recommendations from friends and medical
professionals for several surgeons who, other than Dr. Smith, might perform
surgery if it proved to be necessary. One of the recommendations was for Dr.
John Moore of St. Joseph's Hospital in Atlanta.
Dr. Moore had been Dr. Michael Smith's partner before Tenet
lured Dr. Smith away to head the cardiac surgery unit at Atlanta Medical Center.
As a bargaining chip in the effort to lure Dr. Smith to Tenet, Tenet had agreed
to help him with the lung cancer screening clinical trial he wanted to conduct.
We decided to use Dr. Moore for a second opinion on whether or not Kathie really
needed surgery to treat a likely lung cancer, and made an appointment with his
office.
From among the oncologists recommended to us by friends was
Dr. Colleen Austin. Dr. Austin was also recommended by another physician. We
made an appointment with Dr. Austin in case her assistance was needed to treat
Kathie with chemotherapy.
By this time, Kathie and I were talking to anyone and
everyone who had experience in dealing with lung cancer. One of our neighbors,
with whom we had regularly played bridge, had died of it, but only after a
valiant fight that considerably extended his life expectancy. His family gave us
information on immune system stimulants he had taken in massive amounts to
enhance his body's ability to fight his cancer.
Because Kathie hadn't been conclusively diagnosed with lung
cancer yet—there was no biopsy of tissue to confirm a cancer—it didn't seem
critical that we take that course. I went to the health food store where the
neighbor had purchased his supplements. I learned that there were a mind-numbing
number of immune system stimulants. After talking with the store manager, I felt
he seemed more interested in selling expensive products than in discussing how
they work, so we put that on hold.
11. The pressure is on
Although we had gotten a few warning signals, we kept coming
back to Dr. Smith's declaration that CT scans plus a PET scan could identify a
suspect cancer with 90 to 95 percent accuracy. That meant the odds of what had
turned up in Kathie's scans were 90 to 95 out of 100 that a cancer was involved.
And, as Dr. Smith warned me on several occasions: "Noel, this is a cancer!"
With a growing cancer—especially an aggressive small cell
lung cancer—your odds of survival go down with each passing day, with each
doubling of the cells in the tumor, with each possibility that the cells are
spreading to other parts of the body.
We were scheduled for a July 23 pre-operation meeting at St.
Joseph's to finalize Kathie's surgery, now scheduled for 7:30 a.m. on July 29.
The date had been moved up because Dr. Smith was leaving town for a trip
immediately after that, and wanted to complete the surgery before he left.
Our first appointment with thoracic surgeon Dr. John Moore
for a second opinion on July 24 was canceled because he was running late.
Frustrated that critical decisions had to be made quickly, and time for
gathering information was running out, we rescheduled for the morning of July
25.
At 11:30 on the 24
th,
we attended a pre-op session at St. Joseph's Hospital in Atlanta. We were told
to have Kathie at the hospital by 5:30 a.m. on Monday, July 29, to check her in
for the surgery.
At 1:30 on the afternoon of the 24th, Kathie underwent a
number of pulmonary function tests at the hospital to be sure her lungs would
withstand the rigors of surgery.
After that, we met with the anesthesiologist who went over
with us the procedures that would be followed to render her unconscious for the
surgery.
Kathie was particularly apprehensive about the discussion of
how her lungs would automatically collapse when the surgeon opened her chest
cavity. She looked pretty much like a deer caught in the headlights of an
approaching car.
12. We attend the GILCR seminar again
On the evening of July 24, we attended for the second time
the two-hour seminar at GILCR that we had attended a few weeks earlier.
This time, our daughters and their significant
others—husbands and boyfriends—attended with us. Like us, they wanted to learn
all the could about lung cancer and how it might be affecting Kathie.
My training as a journalist—I've been a newspaper reporter
and editor, have a master's in journalism and taught journalism and public
relations at two major universities—had led me to take copious notes at the
first seminar, before Kathie's diagnosis. This night, with surgery in the
offing, I took far more notes than before.
Dr. Louis Lovett, first on the program that evening,
mentioned that Tenet's Atlanta Medical Center was one of only ten centers in the
United States screening for lung cancer using CT and PET technology.
Mention was made at the meeting of the pioneering work of Dr.
Hadyn Williams, chief of nuclear medicine at the Medical College of Georgia, who
had worked with Claudia Henschke at Cornell, and Dr. A. Hamblin Letton. Mention
was also made of pioneering work in Japan at Nippon Kyobu Geka Gakkai Zaoshi
(did I spell that right?) in the use of PET scanning in lung cancer screening
and diagnosis.
As for the GILCR screening study at Atlanta Medical Center,
we were told that 275 patients had by this time been enrolled, and a total of
four cancers had been found in the high-risk subject group. Mention was made
that while PET scanning was not yet approved by the medical profession or
insurance companies as a screening tool for lung cancer, it was approved for
staging firmly diagnosed cancers.
The statement was again made that PET scanning was 95 percent
accurate in diagnosing lung cancers.
The urgency of treating suspect cancers was emphasized in the evening
presentations. Data were presented warning that in non-small cell lung cancer (NSCLC),
tumor cells divide on average every 99 days, in a range of 90 to 120 days. In
the case of more aggressive small cell lung cancers (SCLCs), doubling of cells
occurs every 26-30 days. Survival rates are greatly improved if lung cancers are
detected and treated early, before metastasis.
13. The second opinion: Another warning
On the morning of June 25, Kathie and I met with Dr. John
Moore for a second opinion. He pointed on Kathie's CT scan films to two masses
in the upper lobe of one of her lungs, one of normal lumpy shape, the other
dumbbell shaped. The masses were in the area where the trachea splits into the
two bronchi.
Dr. Moore said that he and Dr. Smith disagreed on the
efficacy of PET scanning. He was not as big a proponent of PET scanning as was
Dr. Smith, his former partner. He said he thought there was a 60 percent to 65
percent chance—at best a 70 percent chance—that the masses in Kathie's lung were
cancer. He emphasized that inflammations of the lung can register as false
positives for cancer on PET scans.
He then said that if a mediastinoscopy had turned up negative
results, he'd go ahead with a thoracotomy. He thought getting tissue biopsied
was more important than a positive PET scan.
He went on to discuss survival rates. Surgery is performed on
many stage IIIA cancer patients, and on some IIIB patients, he said. Kathie was
thought to be a stage IIIA. Dr. Moore then returned to the subject of accuracy
of PET scans. Four years earlier, he said, he had heard radiologists say PET
scans were the greatest thing ever. But he didn't think PET scans were as
accurate as once held. Prayer, on the other hand, he felt to be positive.
I think now that Dr. Moore was trying to warn us, albeit
indirectly, that he was suspicious of the GILCR study. I don't know that to be
the case—it's just an impression I now have. At any rate, we pressed him.
What did he recommend, we asked?
He answered that if a mediastinoscopy—a medical procedure to
biopsy the mediastinal lymph nodes for the presence of cancer requiring a day or
two at the hospital— came up negative, then a pulmonectomy would be advisable.
He himself would more than likely do a lobectomy if a mediastinoscopy did not
indicate a cancer. A ventilation perfusion scan before the pulmonectomy surgery
would be needed to assure that the patient could withstand the aftermath of a
lobectomy. Kathie's pulmonologist should be consulted, he advised.
14. Last meeting with surgeon Smith
On the afternoon of June 25, Kathie, two of our children and
I went to Dr. Smith's office for the pre-op consultation. He was busy talking to
some medical students and was an hour and a half late for the appointment. The
children, who had come with us and had to get back to jobs, were ready to leave
when he finally arrived.
The main purpose of the consultation turned out to be the
signing of surgical consent forms, although Dr. Smith answered some questions
and briefly discussed the results of several tests Kathie had taken, including
maximum oxygen uptake.
He said the operation would take 35 minutes to one hour to
get epithelial squamous cells for examination, plus another hour and a half if
he had to do a resection. He mentioned that PET scans were 94 percent accurate
for detecting lung lesions, and 88 percent accurate for detecting metastasis to
lymph nodes. Kathie's PET scans indicated two tumors plus metastasis.
This was the last chance for Dr. Smith to talk about the
serious consequences of the operation. This is important. He never told us the
mortality statistics for the kind of surgery Kathie was about to undergo. Nor
did any of the other doctors with whom we consulted. So I'll tell you what none
of the doctors would tell us. Of those over 65 who undergo a partial lung
removal, five percent die. Of those over 65 who have a full lung removed, 16
percent die.
We did know by the end of this meeting from email exchanges with
Dr. Smith, telephone conversations and the pre-op consultation that there would
be two stages to Kathie's surgery.
In the first stage, a mediastinoscopy would be performed. A
small slit would be made in the area of the breastbone. An instrument would be
inserted that permitted the doctor to look at the mediastinal lymph nodes, and
take a tissue sample from them for biopsy. If the mediastinoscopy was negative
for cancer, we were told, the next step would be a thoracotomy. This involved an
opening of the chest cavity between two of the left ribs. The lungs would
collapse as soon as the surgeon's opening broke the pleural membrane, and with
it the vacuum inside the thoracic cavity. A portion of the lung where the
suspect tumors were located would be removed, and the suspect masses would be
biopsied for cancer.
Kathie is still of the opinion that if the mediastinoscopy
was negative for cancer, the first surgery would end there, and she would be
awakened to go home after a day or two. A second surgery would follow if the
tumors grew.
While she thinks that, according to my notes, the plan was to
perform both a mediastinoscopy and thoracotomy to remove the suspect tumors,
thereby saving her the stress of two separate anesthesiologies.
15. The surgery is performed
Kathie's surgery was performed as scheduled on the morning of
July 29.
At about 11:45 a.m., Dr. Smith came to the waiting room to
inform assembled family members that he had performed a wedgectomy and removed
some inflamed tissue elsewhere in the lung. All the tissue was negative for
cancer.
Many tears were shed by the daughters, who had been very
frightened and were relieved and overjoyed to learn that their mother's biopsies
were negative.
Dr. Smith said immediately after the surgery that the false
positive for lung cancer was the result of an aspergilloma infection that Kathie
had.
Responding to the invitation for an advance copy of this
article, he said in an email to me on June 27, 2004, that
"As
you recall her biopsy did diagnose an aspergillosis infection in her lung which
was previously unknown and was deemed to be in need of treatment by her
infectious disease specialist. This would have gone undetected had it not been
for her participation in the lung cancer study."
In actuality, two rare disease specialists with offices at
St. Joseph's Hospital were involved in culturing the tissue removed from
Kathie's lungs. It takes a number of days to try to culture and confirm
aspergillosis from a tissue sample. As it turned out, the specialists were never
able to verify that aspergillosis was present in the removed lung tissue. Nor
were they able to verify any other reasons—viral, bacterial, fungal or
chemical—that the tissue might have shown up positive for cancer on Kathie's PET
scans.
Be forewarned—medicine is still far from an exact science. We
never did find out what might have fooled the PET scanner into thinking that
what turned out to be benign masses in Kathie's lung was a malignant cancer.
Like Dr. Casarella mentioned earlier in this article, whose scans had mistaken a
fungus infection that had cured itself long before, Kathie may well have fallen
into the category of the millions of Americans carrying such benign lesions that
fool expensive medical technology.
Doctors would have us believe, from the persuasive messages
disseminated by the public relations specialists at the American Medical
Association, that medical mistakes are rare, and that doctors should be excused
from the consequences of their mistakes lest the cost of malpractice insurance
make medical practice so expensive that doctors go out of business and everyone
is denied health care as a result.
According to the results of a new national review of Medicare
records by a Denver agency release in late July 2004, medical mistakes are all
too common. The number of hospital patients who die from preventable errors may
be twice as high as previously estimated. The finding would make medical
mistakes the third-leading cause of death in the country, behind only heart
disease and cancer.
Kathie and I elected not to sue for malpractice. Better, we
thought, to make Kathie's story public.
16. The aftermath
For Kathie, who had been told recovery would take about six
weeks, there was a much longer and extremely painful recovery period of six
months. She still hasn't regained full use of her left arm two years later, and
probably never will.
I would be remiss if I did not mention that a few days
after the surgery, while Kathie was still connected to tubes and a machine
draining her chest cavity, Dr. John Moore (the second opinion physician) briefly
visited her Intensive Care Unit hospital room at St. Joseph's Hospital in
Atlanta. "I told you so," he said pointedly. The remark could be taken to mean a
number of things, but Kathie and I have taken it to mean he had been trying to
warn us off in the second opinion consultation before the surgery.
17. Dr. Brawley objects to the GILCR study
At about this time, while I was spending night and day at
Kathie's bedside at St. Joseph's Hospital, I received an email from Dr. Otis W.
Brawley.
Dr. Brawley at the time was professor of medicine, hematology
and oncology at Emory University School of Medicine and professor of
epidemiology at Emory's Rollins School of Public Health. He was also serving as
associate director of the Winship Cancer Institute at Emory University and as
director of the Georgia Cancer Coalition Center of Excellence at Atlanta's Grady
Hospital, an important medical facility that, among other missions, treats many
of the medically uninsured in the Atlanta metro area. From 1995 to April 2001,
Dr. Brawley had served at NCI headquarters as the assistant director of the
National Cancer Institute's Office of Special Populations Research. Before that,
he had been a senior investigator at NCI, and from 1993 to 1995 headed NCI's
intramural prostate cancer clinic.
Dr. Brawley had apparently read my op-ed piece in the Atlanta
Journal-Constitution. He may have taken exception to some or all of it.
I learned that he had written a letter to the American Cancer
Society's Southeast Division, which has responsibility for several states
including Georgia, recommending that it withdraw its approval for Dr. Smith's
GILCR screening study at Atlanta Medical Center. Any reservations he had about
Dr. Smith's research study certainly deserved consideration.
From Kathie's hospital room, I sent him an email that begged off
answering his email, noting that I'd get back to him after my wife had
recovered. To my regret, I never did so.
Dr. Smith subsequently told me that Dr. Brawley had objected to
the Cancer Society about his study. He said that he had successfully defended
the study with ACS, which continued to sanction his work regardless of Dr.
Brawley's objections. He also told me at a later meeting that he had lunch with
Dr. Brawley to discuss the issues involved, but had been unable to resolve
differences between them. I never learned exactly what Dr. Brawley's objections
were to the GILCR study.
18. At Kathie's bedside, I begin to question the surgery
In Kathie's room in the Intensive Care Unit at St. Joe's I began
to question what had taken us so quickly to unnecessary surgery.
I had read about how the head of the radiology unit at Emory
University Hospitals underwent unnecessary surgery when his CT scans were
misdiagnosed.
I had heard Kathie's pulmonologist recommend that we wait for
three months to see if the suspect masses in her lungs grew instead of going
ahead with surgery. A cancer was more likely if the tumors grew.
I had heard Dr. Smith's former partner, when asked for a second
opinion, express doubts about the accuracy of PET scans.
I'm not sure if I learned of Dr. Brawley's objections to the
GILCR study before or after Kathie's surgery.
Despite the flags being raised, in that critical period from the
cancer diagnosis on July 12 to surgery on July 29, we mostly heard Dr. Smith,
the trusted physician of the GILCR study, telling us that it was urgent that the
cancer be identified and surgically removed.
19. The immediate aftermath
Kathie was released from St. Joseph's Hospital for home recovery
Aug. 8, almost two weeks after she was admitted for the surgery. Her release was
several days later than had been anticipated. Her release from the hospital was
delayed for two reasons.
The first was that she developed an ileus. That is a severe
colic accompanied by repeated vomiting due to an intestinal obstruction. We were
told it was likely due to medicines she was taking to control pain from the
surgery.
Dr. Smith was still out of town. Doctors covered for him, but
were pretty much unfamiliar with Kathie's case. They visited her room at best
once a day to review vital sign records.
Some advice to those reading this: be careful about consenting
to surgery, unless your life is threatened, if your surgeon is going to be out
of town during your recovery.
The other reason her release was delayed was a misunderstanding
by the doctors covering for Dr. Smith during the last few days of his absence.
For several days, they were unaware that they were supposed to be filling in for
him. A physician from this office showed up on Aug. 7, two days late, to check
to see if Kathie was ready to be released. We had to go looking for the same
doctor on Aug. 8 to get her release signed.
At home, Kathie continued to endure severe pain. She was
administered oxygen around the clock by one machine in our upstairs bedroom, the
other downstairs. She connected to the machines with neoprene lines hooked up to
them and to her. Baths were initially out of the question, but I created a bench
for her in the master bath. Using a flexible shower line that I installed, we
were able to let her take showers at first with my help, and later alone.
20. In defense of Dr. Smith
We like to think of medicine as a science. It is that, but not a
perfect science. Physicians make mistakes. They're human, they don't always have
all the information they need and they're overworked.
Dr. Smith was working on the cutting edge, in an area where
there's a bias against doing research. Compared to breast and prostate cancer,
lung cancer research is underfunded. It's not a particularly popular research
area. Because most lung cancers are the result of smoking, a behavior people
choose, there's a feeling in the general public, often reflected among
researchers, that lung cancer is the fault of people who get it.
That bias neglects such facts as that one in six lung cancer
patients never smoked. It also fails to comprehend that those who chose to
smoke were subject to the a hard advertising sell over the years that got people
them hooked. It ignores the fact that much of the advertising was based on
misleading advertising, some of it featuring doctors testifying to the health
effects of smoking. It fails to recognize that nicotine is highly addictive, and
it takes only two cigarettes to addict a smoker. Despite all that, there's no
denying that a bias against finding a cure for lung cancer exists.
Dr. Smith is to be commended for being willing to devote time to
an underfunded and not particular popular research niche where there is a huge
need for medical investigation.
Finally, keep in mind that it was a radiologist, not Dr. Smith,
who determined that something on Kathie's scans looked like a cancer.
21. A fourth physician questions the surgery
On August 14, I had an appointment with our family physician,
an internist with special skills in cardiac treatment. He told me that in his
opinion CT and PET scans gave too many false positives, and that Kathie's
surgery was probably unnecessary. He's normally not emotional when we talk, but
he was quite animated in this case. I passed a vetted version of what he had
said on to Dr. Smith in an email, asking that we talk further about the problem
of false positives.
I added our internist to the list of physicians saying that
the surgery was unnecessary or unwise. The list now included:
• Dr. Smith's former partner, surgeon John Moore.
• Kathie's pulmonologist.
• Our internist.
I didn't include on the list Dr. Brawley, the eminent
physician who had headed the Prostate Cancer unit at the National Cancer
Institute, who had questioned the GILCR research project for reasons I never
learned.
22. I write two books
As Kathie was recovering in her hospital room, I continued to
read extensively about cancer, but still had little more than a layman's
knowledge of lung cancer screening. I decided to correct that.
The result was that I started an online newsletter about
cancer research, and since July 2002, read enough about the subject to write two
books.
The first book, New Hope: Avoiding Lung Cancer, was
published in 2003. It is primarily an argument for people to quit smoking with
advice on how to go about it. It also discusses the efficacy of current
technology for screening high-risk populations for lung cancer, and talks about
measures present and former smokers can take, above and beyond quitting smoking,
to reduce the risk of lung cancer.
The second book, Conquering Cancer 2003, was published
in 2004. It is a summary of the most significant research in screening for,
diagnosing and treating cancer announced during the year 2003.
To write Conquering Cancer, I daily read through the
most important cancer research announcements. The most important of these
stories I summarized in a monthly online newsletter called "Current CancerNews"
that I posted on the Internet. Subscriptions were free for anyone who wanted to
read the information being posted. These monthly stories I consolidated into an
eBook to keep down the cost to those who wanted it, although a conventional
version with paper pages is also available.
23. Why I decided to write this article
Early in 2004, Kathie and I were concerned when we heard that
a routine CT scan in Wisconsin of the husband of her only sister had turned up
something suspicious in one of his lungs. We were happy to hear a few months
later that a subsequent CT scan had detected no growth in the mass detected, and
that the threat of cancer was lifted.
In late May 2004, Kathie and I drove to Chicago for a family
wedding, some sightseeing and to allow me to attend the big annual book show,
BookExpo America. From there, we drove to Wisconsin to spend a week at Fox Hills
Country Club near Green Bay with the relatives.
There I talked to Kathie's brother-in-law. It seemed to me
that his suspect lung cancer had been treated prudently. A CT scan had found a
mass on one of his lungs. They waited a few weeks and then gave him a follow-up
scan to see if the mass was growing. It wasn't, so the diagnosis was "it's not
cancer." There was no expensive PET scan as part of the diagnosis. There was no
elaborate immediate surgery to biopsy suspect tissue, no pressure to undergo an
excruciatingly painful surgery and recovery with the risk of never regaining
lung capacity.
Driving back to Atlanta, I thought long and hard about that,
and began to outline this article in my mind. Soon after getting back home and
unpacking, I decided there was a public right to know Kathie's story. Spreading
the word might well help others from an experience similar to hers. So I sat
down and began to write from the extensive notes I'd taken during her crisis,
the audio tapes she had recorded at the time, the email and medical records we
had from the period.
I did my best in telling Kathie's story to do so accurately.
As I said in the beginning of the article, I'm a writer and journalist, not a
doctor, so I could have gotten one thing or another wrong about the technology
or the exact chronology. If I've said anything that is incorrect, and a reader
notes the mistake, please let me know so I can make it right.
24. The economics of cancer screening
So, what is my opinion now of screening for lung cancer using
CT and PET scanning? I think it's impractical. Briefly consider the economics.
Lung cancer is mainly the result of tobacco use. An estimated
87 percent of lung cancers are caused by smoking. True, one out of six lung
cancers occurs in people who have never smoked. Those cases occur mostly in
innocent people exposed to second-hand smoke, to radon or to microparticulates.
An estimated 90 million U.S. citizens are past and present
smokers. About 23 percent of the population, perhaps 43 million people, continue
to smoke.
A CT scan directly costs only about $75 to give. However, CT
scans, whether for screening or for diagnosis, are profit centers for
hospitals—and for private companies that give them from vans at places like
churches. The mobile vans that provide them for profit generally charge $200 to
$600 to give them. People who get them from their doctors or hospitals are
charged in the neighborhood of $300 to $600.
CT scans for the purpose of diagnosis are generally covered
by medical insurance, but much of the U.S. population is not insured. CT scans
for screening purposes are usually not covered by medical insurance.
PET scans are far more expensive than CT scans. They cost in
the neighborhood of $2,000 to $4,000, although the direct cost of giving them is
again far lower. Like CT scans, they are profit centers for hospitals and mobile
entrepreneurs.
For the sake of argument, let's assume that 10 percent of the
90 million past and present smokers are in a high-risk group—over 55, with a 30
pack-year history of smoking—that we decide initially to screen. That's nine
million people we'll be screening for starters.
Assume further that we will initially give a CT scan to the
nine million people to screen them for possible tumors, at an average cost of
$450. That's $4 billion. Further assume that half of those, or 4.5 million
people, require a CT scan with contrast at an average cost of $500 each. That's
another $2.25 billion. Now assume that half of those, 2.25 million people, need
a PET scan at an average cost of $3,000 each. That's an additional cost of
$6.675 billion to screen our initial test group of nine million.
But our first-year costs are not yet complete. There will
also be some costs for surgeons and oncologists to treat the new cases of lung
cancer we detect. In the nine million present and former smokers over 55 that we
screened, we might expect to find in the neighborhood of 200,000 lung and
related cancers that would not have been found by routine chest X-rays. Assuming
a cost of around $40,000 per tumor for surgery, chemotherapy, radiation and
other treatment, that's another $8 billion in costs, over and above the $13
billion screening cost. Now our total first-year cost is $21 billion. (Expect
also that all the radiation to which we expose our patient group will cause some
cancers that would not otherwise have occurred.)
Will the nation's already stressed health system bear the
additional expense?
Now, before we answer "no" to that question, consider that
the present cost of smoking to the health system is around $75 billion per year.
Double that to allow for other costs to the economy, such as the more frequent
absence of smokers from the workforce because of illnesses, and smoking is
costing the economy in the neighborhood of $155 billion per year.
The $21 billion cost I roughly estimated above for screening
a high-risk group is far less than the current cost of smoking to the economy.
Further, it's a minuscule part of the current $1.7 trillion estimated annual
cost of health care in the United States. But for political reasons I discuss
immediately below, I don't believe the nation's medical provider system or
health care insurance system will tolerate the additional cost of screening.
25. So what's the answer?
The answer to screening for lung cancer in high-risk
populations, in my opinion, is not CT and PET scans. The answer is simple and
inexpensive.
The first part of the answer is to get people to quit
smoking. It's far less expensive to outlaw cigarettes than it is to treat lung
cancer. There will, of course, be a public outcry. Only a muted cry will come
from the smokers whose supplies would be cut off. Their cry will be muted
because they have little political clout. A much louder cry will come from the
tobacco industry and from the states that have become dependent on revenue from
the tobacco companies. They have considerable influence or clout.
Short of outlawing tobacco, campaigns to persuade people to
quit smoking are also more cost-effective than treating lung cancer and the
other diseases caused by smoking—heart disease, chronic obstructive pulmonary
disease, stroke and a host of other ailments.
The second part of the answer, in my opinion, is serum
testing. A number of serum tests that detect various types of cancer at the very
earliest stages—far earlier than the cancers can be detected by CT or PET scans,
much less X-rays—are already in large-scale clinical testing. Some of the tests
detect predictive proteins in urine. Others detect the warning proteins of
cancer in the blood. Some are based on proteomics (complex computer analysis of
serum proteins), some are not.
In responding to my invitation for a copy of this article,
Dr. Smith wrote in an email to me that "...no modality has been shown to be 100
percent accurate in the early detection of lung cancer. I am unaware of any
non-invasive modality for the detection of any cancer that has zero percent
false negatives." Actually, a Colorado company that developed a
proteomics-based serum test claimed that in early trials it was 100 percent
accurate in early detection of lung, prostate and breast cancer, and gave zero
false positives. That test, the last I heard, was in large-scale testing at the Karolinska Institute in Sweden, home of the Nobel Prize for medicine.
In those tests, the results were positive but not nearly as accurate as the
early proteomics-based tests.
Nonetheless I expect that it won't be long before one or another of these
inexpensive serum tests is on the market, providing a low-cost method for
annually screening high-risk subjects. I know Dr. Smith will share my enthusiasm
if and when such tests become available.
Once an inexpensive serum test used in screening has
indicated the presence of an early-stage cancer, it's still necessary to locate
the cancer. Here, CT and PET scanning will likely continue to play an important
role.
As for treating the lung cancers discovered by serum tests, remarkable
progress is being made in that area as well. It's remotely possible that
anti-tumor agents, perhaps delivered by viral vectors, agents far less brutal
than the surgery, chemotherapy and radiation therapy used today, will be
introduced in my lifetime. I certainly hope and pray that proves to be the case.
