Progress in the War on Cancer
– New Technology Poised to Join Screening in Reducing Cases and
Deaths, Physician Says
By Garret Condon
Dr. Carolyn D. Runowicz is director of the Carole and Ray Neag
Comprehensive Cancer Center at the University of Connecticut Health
Center in Farmington. She is co-author of the new book "The Answer to
Cancer" (Rodale, $24.95, 304 pages) with her husband, Dr. Sheldon H.
Cherry, a clinical professor of obstetrics and gynecology at Mount Sinai
School of Medicine in New York, and with Dianne Partie Lange. Runowicz
also is the second vice president of the American Cancer Society. What
follows is an edited version of a question-and-answer session about
cancer.
Q: How is the war on cancer going?
A: Depending upon the cancer, and depending upon whether you're
looking at incidence or mortality, it's a 25-to-50 percent reduction in
either incidence [the number of new cases per year in a given population
group] or mortality [the death rate from a particular kind of cancer].
... We've made tremendous strides in screening and early detection, and
we're, I think, poised for more progress in those two areas through new
technology such as proteomics and nanotechnology.
Q: Can you describe those technologies briefly?
A: Proteomics is the study of protein patterns [in blood or urine] to
look for unique patterns in a cancer for early detection and screening.
Results are promising in breast and ovarian cancer. We may also be able
to identify markers of response to determine if treatment is working.
Genomics is studying the human genome, [which has allowed us] to
identify genetic changes, for example the BRCA1 and BRCA2 genes for
breast and ovarian cancer. And nanotechnology [the creation of
ultra-miniaturized tools and particles] is still in its infancy, but
[it] may allow us to improve drug delivery and also evaluate response to
therapy.
Q: Aren't all of these technologies in early stages of development?
A: I think we're on the cusp. I think that is going to move us even
further into the early-detection and screening mode. And I think that's
the secret to success. I mean, our book, "The Answer to Cancer," is
about prevention.
We currently have available to us, today, most of the drugs that we
need to treat cancer if we can detect cancer at an early stage.
[Runowicz went on to describe results from a tamoxifen study in the
late 1990s that showed "proof of principle that we have, today, drugs
that can prevent cancer in a high risk group."]
Q: You don't think the use of tamoxifen to prevent breast cancer
should be controversial?
A: No, I definitely don't think it should be. I think we know what it
can and can't do. And for a woman who's at high risk of breast cancer,
we know we can reduce her risk of breast cancer. Breast cancer, for her,
is a much greater risk than the [drug's] side effects, and particularly
if we give it to women under the age of 50. In the trial, when you begin
to look at different groups, and different risk groups and different age
groups, you see that women with the highest risk as well as women under
the age of 50 had the greatest benefit with the least amount of risk.
Q: Are you suggesting that all women at high risk should be taking
tamoxifen?
A: I think all women should know their risk assessments, which I
think is a new paradigm in medicine. We can assess for breast cancer
risk by a simple model, the Gail Model or the Claus model. And these are
models that have been validated in clinical trials. If a woman has found
that she has an increased risk either based on family history or based
on one of these models, in my opinion, in this day and age, she needs to
discuss with her physician risk-reduction strategies. And the
risk-reduction strategies include weight loss, exercise, thinking twice
about being on hormone replacement, thinking twice about going on a drug
like tamoxifen.
Q: Is the popular perception of risk flavored by whatever the current
media or public relations emphasis is?
A: If you ask a patient what her risk of breast cancer is ... they'll
always predict that it's higher than it actually is. ... Risk assessment
is almost a new science. It just is not well practiced and not well
understood by patient.
Q: Shouldn't there be more emphasis in the war on cancer to working
on diet and working on lifestyle issues?
A: There is a lot of work. We know, for example, through
epidemiological research, what is good in your diet vs. that which is
not good; however, it is very hard to get that message across to the
American public. In my experience as a physician and in my experience
with friends, you know, going out to dinner, Americans like the easy
way. They like the pill that prevents cancer - as opposed to cutting
back on total calories. It's not only what you eat, it's how much you
eat.
Q: There are a lot of popular diets, like the Atkins diet, that may
not necessarily be cancer-preventive diets. What do you tell your
patients about such diets?
A: First of all, I tell them "diet" is a very bad four-letter word.
Because you can't think of your lifestyle as a diet; you have to think
of it as "this is the way that I eat," and forget about the word "diet."
The minute you say diet to someone, they think of a six-month program,
they think of a 30-pound weight loss, and what that does is give you
this yo-yo effect, so they lose the 30 pounds and then put on 40 pounds.
So, it's really bad, and it's bad for their heart, and it's bad for
cancer risk, and long-term studies on the Atkins diet show that it
doesn't - in the long run, everyone puts their weight back on. ... And
it doesn't mean that you can't have a cookie. ... Everyone laughs at me,
but I cut my food in half, and so I'll have a cookie, and I'll cut that
piece into fours, and I'll take a little piece, and I wrap the others
up, and I put it away. ... It's not like I'm starving myself or that I'm
denying myself. If I want a little piece of cookie, I will eat a little
piece of cookie. I won't eat the whole bag. ... Portion control is very
important.
Q: There seems to be a lot of confusion about cancer screening, from
mammography to the PSA test for prostate cancer.
A: Well, mammography, in my mind, the controversy has been sort of a
trumped-up controversy. There were some investigators [who] decided to
select three out of eight studies, so there was already a selection
bias. And that really did a disservice because the message came out that
mammography was bad. ... The question was [whether ]the benefit [was] as
large as people thought it was. And, in my mind, when you include all of
the data and you don't just self-select three studies, it's clear to me
that that data, plus emerging data, show a survival benefit of 30
percent for women over the age of 40. And it makes sense - it's
biologically plausible - because the smaller your cancer, the earlier it
is. The earlier the stage, the higher the cure rate.
Q: For women over 40?
A: Women 40 and over. At age 40, I start yearly mammograms and I
practice what I preach. I mean, I've had breast cancer, which is another
reason why I wrote this book. Having had cancer was clearly, hands down,
the worst experience of my life. ... I really assessed everything about
me to try to make my life so that I would be practicing everything I
talk about in this book. I really, religiously exercise. I watch what I
eat. I eat my six fruits and vegetables. I take my calcium. I do my
screenings.
Q: When did you get cancer?
A: In 1992, so that was 12 years ago. I'm 53, so I was 41.
Q: What was the treatment?
A: Everything. Unfortunately, I had a little pea-size tumor; it was 9
millimeters, and it had spread to three lymph nodes, and so I had a
lumpectomy, 12 cycles of chemotherapy. Back then, that was the standard;
you don't need that much anymore. But back then, there were 12 cycles of
therapy, followed by radiation, followed by five years of Tamoxifen, and
now I'm on Femara [letrozole], the aromatase inhibitor, which may make
Tamoxifen in post-menopausal women a drug that is not as used.
Q: Isn't the flip side of pushing cancer prevention that people who
get cancer will blame themselves for not having prevented it?
A: Oh, they always do. Everyone always does. It's a uniform mea
culpa. And some cancers are preventable. For example, lung cancer - if a
person is a smoker or was a smoker, they rightly blame themselves and
that is just sort of a fact of life. There are other cancers that the
person blames themselves and it's not so much that they could have maybe
prevented the cancer, but they could have early-detected it and maybe
prevented it. ... Now, there are other cancers, like pancreatic cancer -
although there is a relationship with smoking there. But there are other
cancers that we can't prevent or we can't screen for. But everybody,
including myself, was, "What did I do that I got breast cancer?" You
know, what was it about my life that I did? And I decided - and my
doctor reinforced it - that it was the birth-control pill when I was
younger. That may or may not be true. But it's one of those mea culpa
experiences, and everyone does it.
Q: But it seems to me that it's not a helpful attitude at that stage.
A: It's not. And do you know what I do? I say, "Drop the guilt at the
door. We've got to move on." And that's what you have to do.
