Treatment controversies are likely to make you feel
profoundly uneasy. You may even avoid seeking another
opinion for fear of being overwhelmed with contradictory
information and advice. Whom should you trust? It's quite
hard enough dealing with a life-threatening illness, but
to also find that your doctors don't agree on treatment
is even more disquieting. You are not alone in feeling
this way. Jeff Belkora, a volunteer decision consultant
at the Community Breast Health Project of Palo Alto,
advises breast cancer patients that:
Not running into controversy in breast cancer may be a
sign that you need to gather more information! Although
the lack of consensus about how to treat breast cancer
can be frightening, at least researchers, clinicians and
patients are experimenting with new techniques and
procedures, and generating "controversy." From their
experiences and learning, you can strive to craft a
strategy that you believe makes the most sense for you.
But be prepared to make commitments: You will have to
choose who and what to believe, and who and what to ignore.
This may be difficult, for while no one has found a breast
cancer treatment that dominates all others on every
dimension, people do have favorites, and they tend to
advocate them with passion. Each may appear convincing,
even as they are contradictory. That's why you need time
to analyze everything in a way that's comfortable for you.
Aim to be comfortable and clear about the reasoning behind
every breast cancer decision you make.1
Currently, the most dramatic and urgent controversy in the
treatment of metastatic breast cancer exists between
physicians who believe that a very aggressive approach
early in the progress of metastatic disease raises the
possibility for long-term remission or even cure, and those
who adhere to the more conservative intensive standard
treatments, and who feel that until definitive results
confirm the efficacy of high-dose chemotherapy, the
procedure itself is too toxic to routinely offer to
patients.
Since there is clearly some dose-response ratio with
chemotherapy, in recent years there has been a trend toward
the use of very aggressive treatment protocols, generally
in patients under 50 with no other significant complicating
health problems. This section will focus on one of these
major controversies, involving the use of high-dose
chemotherapy (HDC) with bone marrow or stem cell support
(sometimes called "transplant" or "rescue") with metastatic
breast cancer patients.
You should be aware that this article, while it goes into
some detail on this issue, is not intended to provide a
full or substantive sense of the treatment issues involved
with HDC, but only a feeling for the nature and complexity
of this controversy. If you are considering this treatment,
think of this as a jumping-off place for your investigations.
If you are not a candidate for this treatment, read it for
the sense it may give of how physicians, scientists and
patients work to resolve an important treatment controversy,
as well as some of the less obvious confounding variables
that come into play, concerning the economics and politics of
health care choices.
While this procedure is often referred to in popular and
professional literature by differing initials and names, for
example, as autologous bone marrow transplant (ABMT), or
peripheral stem-cell transplant or re rescue (PSCT; SCR), this
article will refer to this treatment simply as high-dose
chemotherapy, or HDC. HDC will thus be differentiated from
intensive chemotherapy regimens which do not require
stem-cell or bone-marrow rescue for treatment survival,
but for which growth factors like Neupogen (granolocyte
colony stimulating Factor, or G-CSF) that stimulate white
blood cell production in the bone marrow are frequently
required.
HDC involves the use of very high doses of varying
combinations of standard chemotherapy drugs that would be
fatal to the blood-cell-producing bone marrow without
reinfusion of the patient's own previously harvested and
frozen stem cells (the immature cells from the peripheral
blood that form white and red cells and platelets) or bone
marrow. The use of the patient's own stem cells, rather than
those from a donor, is why this kind of transplant is called
autologous. This treatment usually, though not invariably,
follows an "induction" period where the "tumor burden" (amount
of measurable cancer) is reduced through an intensive
chemotherapy regimen. This also enables doctors to make
sure the tumor is still sensitive to chemotherapy before the
high doses are given, almost always a precondition for HDC.
The proponents of HDC believe that "hitting it hard" with
high-dose chemotherapy, before the cancer has had a chance
to become resistant to treatment, confers the best
possibility of treatment success, at least for a subset
of younger, otherwise healthy patients whose tumors are
chemo-sensitive, who have limited disease and who can
withstand the side effects. Depending on the drugs, dosage
levels, general health and specific responses, the acute
and delayed side effects of HDC may include, but are not
limited to, nausea and vomiting, diarrhea, mouth and
intestinal ulcers, bone marrow depression (leukopenia,
thrombocytopenia, hemolytic anemia), anaphylaxis,
peripheral neuropathy, lung damage, hearing loss, cardiac
toxicity, acute infections, and a number of less common
but serious symptoms like renal dysfunction, hepatic
veno-occlusive disease, hemorrhagic cystitis and secondary
cancers. High-dose chemotherapy means these drugs are given
in doses from 3 to 31 times their standard dosage level,
depending upon the combination.
The National Cancer Institute figures say that, according
to the Autologous Blood and Marrow Transplant Registry-North
America, the number of women with breast cancer receiving
HDC grew from an estimated 522 in 1989 to 4,000 in 1994.
"About one-third of all stem cell transplants reported to
the Registry in 1992 were for breast cancer, making it the
most common cancer being treated with this therapy."
2 By 1995, 6,000 cases had been reported to the
Registry,3 and it was estimated by the Registry
director that the actual number of HDC procedures for breast
cancer was twice that number.4
There is no question that HDC produces more complete and
partial remissions following the treatment, and this has
led to great excitement and enthusiasm. There are reports
of women doing very well, with no apparent disease, several
years following the treatment, but there are more reports of
relapses within a few months, and a few reports of long-term
bone marrow suppression and other side effects that are
troublesome and even life-threatening. A certain small
percentage of patients die from the toxicity of the procedure
itself. While yet unproven, this treatment is being widely
offered, with the vast majority of HDCs occurring outside
of clinical trials, and covered by health insurance, despite
resistance on the part of insurers. A significant number of
court cases against insurers have been won by patients
seeking this treatment. Reasons for the difficulty in
enrolling patients into clinical trials are attributable
both to physician and patient reluctance. According to the
Women's Health Network:
Physicians have been reluctant to encourage their patients
to enter these studies, and women themselves have balked
at becoming study participants for a number of reasons.
Experimental drugs require regulatory oversight that limits
access to treatment only through clinical trials, but
experimental medical procedures do not have this requirement.
To the extent that patients can afford experimental
procedures, they probably can find physicians who will
provide the treatment outside of a clinical trial. Women
are turning down clinical trials because they are afraid
that they could be randomized to conventional chemotherapy
rather than HDC with ABMT/BCT. Furthermore, it is often in
the physician's and hospital's financial interest to offer
the more aggressive treatment to patients who can pay for
treatment (HDC with ABMT/BCT costs range from $50,000 to
$200,000) or are insured for the procedure. Seven states
now mandate insurance carrier coverage of HDC with ABMT/BCT
for citizens, as does the U.S. for federal workers.
5
It appears that the safety of the treatment has increased
considerably over the past few years, as treatment centers
have refined their techniques and precautionary measures,
with published figures varying from 5 percent to up to 17
percent for treatment-related "early deaths," occurring up
to a month following treatment. According to the North
American Bone Marrow Transplant Registry, treatment-related
mortality during the first 100 days following HDC has
dropped from 22 percent in 1989 to 5 percent in 1995.
6 During the same six-year period of decreasing
mortality, however, the percentage of patients receiving
HDC who had metastatic breast cancer (as opposed to
high-risk primary breast cancer) decreased from 93 percent
to 50 percent, with a corresponding increase from 7 percent
to 50 percent in high-risk patients who had loco-regional disease.
7 So it's likely that fewer very sick
patients with extensive pretreatment--who would certainly
be more at risk for adverse affects of HDC--received the HDC.
"Based on the recent studies, the mortality for this
treatment has decreased substantially in the past few
years," concurs oncologist Craig Henderson from the
University of California, San Francisco. "However, it's
not clear that high-dose chemotherapy with ABMT is the
best treatment for any group of patients, that it will
cure any patient that would not be cured by other
treatments, or that it will prolong survival to a greater
extent than commonly used conventional dose chemotherapy."
8
Dr. Karen Antman, Chief of Medical Oncology at Columbia
Presbyterian Medical Center in New York City, urges careful
patient selection. Patients with advanced refractory
disease are not likely to benefit from the procedure, she
warns, but goes on to say that of those untreated,
chemo-sensitive patients who do achieve a complete
response (CR), "A quarter to a half of those achieving
CR have no evidence of progression with follow-up intervals
of two to four years in trials at multiple institutions."
9
Dr. Gabriel Hortobagyi, of the MD Anderson Cancer Center
at the University of Texas, reviewing a decade of Phase
I and II trials of "dose intensification" (yet another
term used for HDC), writes:
Results from these trials suggest that dose
intensification with hemopoietic support markedly improves
overall response rates and consistently results in complete
remission rates approaching 50 percent in patients with
previously untreated metastatic breast cancer. Although
no study has demonstrated an improvement in median survival,
several investigators suggest that 15 percent to 25 percent
of patients treated with dose-intensive therapies remain in
unmaintained remission 2 to 5 years after the procedure. It
is uncertain whether this apparently reproducible group of
long-term survivors is related to the beneficial effect
of high-dose chemotherapy or to the extraordinary patient
selection process undertaken in high-dose chemotherapy
programs.10
To try to answer this question, Dr. Hortobagyi and his
colleagues reviewed a series of studies at MD Anderson,
of 1,581 metastatic breast cancer patients who had been
treated with doxorubicin-based conventional chemotherapy
before 1982, so that they could look at long-term results.
Among the 263 who achieved a complete response (CR), nearly
19 percent remained in complete remission five years later
(3 percent of the total number of patients). In many
respects this group, identified as having a much better
prognosis, perfectly matched the group of patients who meet
the stringent selection criteria required by the trials for
HDC. Not surprisingly, their outcomes were also similar.
11
But for doctors and patients to gain a really accurate
sense of the relative effectiveness of HDC in relation
to standard intensive chemotherapy, however, historical
controls are not conclusive evidence. Women must be randomly
assigned either to the experimental treatment or to the
comparison treatment, which must be the best conventional
standard-dose chemotherapy available. There are three
current well-designed, randomized, controlled trials
investigating HDC, both in women with metastatic breast
cancer and in very high-risk Stage II/III primary breast
cancer patients who have more than ten lymph nodes showing
signs of cancer or who have inflammatory breast cancer.
These multi-center trials, taking place throughout the
country, have had considerable initial difficulties with
enrollment, but expect, before the year 2000, to provide
some real answers. It is likely that by the time you read
this, more will have been clarified about which patients
can actually be helped by this treatment, and which may
do better or as well with conventional treatments with far
less toxicity.
Some oncologists, like Dr. Yashar Hirshaut, have seen a
number of their metastatic patients do remarkably well
and go on to have extended disease-free remissions.
The best results are obtained when we hit hard with the
initial treatment after a recurrence, so as to destroy as
much of the disease as we can--and, if possible, all of it.
If, despite our best efforts, the cancer again recurs, it
may be because it has become resistant to the drugs in
use. We may be able to prevent such a development by
alternating different forms of chemotherapy or by
refining the use of such techniques as bone-marrow transplant...
placing the first and primary emphasis, whenever possible,
on trying for a cure. We attempt to accomplish that goal with
a minimum of disruption of life of the patient but with the
understanding that when we are dealing with an aggressive
cancer, we must act aggressively.12
Other oncologists are concerned that the toxicity of HDC
leaves the majority of women who are unhelped by this
treatment with fewer options when their cancer recurs.
Dismayed at the widespread marketing of HDC outside of
clinical trials, they still consider this aggressive
treatment highly experimental in the metastatic setting.
Dr. Samuel Waxman, oncologist and researcher at Mt. Sinai
Medical Center in New York City, maintains that:
Statistics show that there should be a 50 to 60 percent
response rate with breast cancer with conventional
chemotherapy, 70 percent with intensive chemotherapy, and
maybe 80 percent with high-dose chemotherapy with stem-cell
support. I don't think there's any doubt that marrow- and
stem-cell supported high-dose chemotherapy can give you a
better response rate. I just don't know if that translates
into more time.
Like many other cancer doctors, Waxman believes it is
possible to get equal results with far less toxicity by
"playing out" differing treatment combinations, trying to
outwit the cancer by ingenious combinations of drugs.
There's an art to this as well as a science. There are many
effective chemotherapy protocols and ways of manipulating
hormones. We can rest a person on hormones and then return
her to chemotherapy. If you just bring a woman in and shoot
from the hip with high-dose chemotherapy, it does not insure
improved survival. Sure, there's evidence that the more
chemotherapy you give, the more cancer cells you're going
to kill. But that doesn't mean you're going to cure the
patient, because it's very difficult to totally eradicate
cancer once it is in some recurrent form. Cancer cells are
impervious to drugs at given times in the cell cycle and,
unlike normal cells, have an innate drug resistance, or
rapidly acquire it because of their genetic instability.
To date, only one randomized, controlled study has been
published, involving 90 patients in South Africa.
13 This study demonstrated an impressive
complete or partial remission in nearly 95 percent of
patients receiving HDC (as opposed to 53 percent in the
sub-optimal standard-dose treatment arm) and indicated that
20 percent of patients had extended remissions of two years.
While the conventional treatment arm was less than
state-of-the-art intensive chemotherapy, the results in the
HDC treatment arm were seen as encouraging.
At a 1995 oncology conference, a summary review of HDC
results to date was presented, citing a number of small
studies done over the prior decade, which seemed to indicate
the importance of patient selection in determining success,
and citing a few long-term survivors as possible evidence of
efficacy.
Subsequent studies of HDCT in patients with Stage IV breast
cancer were designed to maximize the response with an
doxorubicin-based induction regimen prior to high-dose
consolidation. Several published studies obtained similar
results, i.e., 15-20 percent progression-free survival at
greater than 2 years. Whether remission induction prior to
HDCT improves disease-free survival remains to be determined
in prospective randomized trials. It is unclear whether
there are specific subsets of Stage IV patients more likely
to benefit from HDCT than others. The most promising area of
study in breast cancer is in patients with high-risk primary
disease. Phase II data for patients with greater than 10
axillary lymph nodes shows 64 percent disease-free survival
at 5 years.14
How is a patient to know which treatment to select, if
there aren't relevant studies available yet? In the absence
of more controlled, randomized studies providing a direct
comparison, a meta-analysis of treatment studies can be
used to provide a broader basis for decision-making, though
no definitive conclusions can as yet be drawn.
Published in 1996, such a meta-analysis was done by the
World Health Organization affiliate ECRI, comparing 49
uncontrolled studies, involving 1,017 metastatic breast
cancer patients treated with HDC, with 35 studies of 4,889
patients with similar characteristics treated with
standard-dose chemotherapy regimens. This constitutes
the most comprehensive review of the available data on
HDC until that point.
The ECRI meta-analysis came to a number of striking
conclusions. According to this study, the initial higher
response rate to HDC appears to have little or no effect
on disease progression and longevity, and may instead be
related to favorable treatment selection, since
chemo-insensitive patients were routinely screened out of
HDC studies. While some subgroups may indeed do better with
HDC, there is no way of identifying these patients for sure,
and thus protecting other patients from the significant
toxicity and mortality of the treatment. Most important,
published studies actually appeared to show higher and longer
disease-free and overall survival rates for standard-dose
chemotherapies. Even in the case of the one randomized
South African HDC trial mentioned above, ECRI lists seven
published trials where survival was equal or better with
standard-dose therapies.15
In early 1998, an extensive review of the medical literature
of HDC for breast cancer appeared in the February edition of
the Journal of the National Cancer Institute. This
review article's excellent bibliography culls out the
important research articles from the hundreds that have been
published to date, and would be valuable for this alone even
if it did not also offer other important insights. The
physicians who wrote this review, JoAnne Zujewski, Anita
Nelson and Jeffrey Abrams, came to many of the same
conclusions that ECRI had. Existing studies, they found,
showed:
The median survival (with HDC) is similar to that of
historic controls, and a small percentage of persons remain
disease-free three to five years after therapy. It is this
small percentage of persons (the "tail on the curve") who
remain disease-free that has led to the enthusiasm for this
procedure.
They also found that the patient selection that is central
to HDC is crucial, leading to overestimation of results by
those who have interpreted the Phase II studies
over-optimistically. In reviewing the largest study of
historic controls (mentioned earlier in this section), done
The authors estimated that 65 percent to 75 percent of
patients eligible for conventional-dose chemotherapy programs
would not be candidates for HDC/ASCR programs. This rigorous
selection process would be expected to identify a subgroup of
patients with a better prognosis. Indeed, in this analysis,
patients potentially eligible for HDC/ASCR did have higher
overall response rates, higher complete response rates, and
a median response rate that was 65 percent longer than
patients treated with the same doxorubicin-containing
regimen in conventional doses.
Zujewski and her colleagues conclude:
Despite the frequency with which this procedure is performed,
the role of HDC/ASCR in the treatment of breast cancer remains undefined. Given the limitations of available data, it is
somewhat surprising that thousands of women have undergone
HDC/ASCR for the treatment of breast cancer. Perhaps
physicians are not as familiar with the limitations of the
data as one might presume.17
Developments continue. In August 1998, a randomized study of
HDC in ninety-seven high-risk breast cancer patients from
Holland was published in the British medical journal,
Lancet. With a median follow-up period of just over
four years, the overall and relapse-free survival in this
study showed "no significant difference between the aptients
on conventional therapy, and those on hgih-dose therapy."
Although the results await confirmation by larger randomized
studies still in progress, the authors conclude:
High dose therapy is associated with substantial cost and
acute toxic effects, but also has potentially irreversible
long-term effects. Until the benefit of this therapy is
substantiated by large-scale Phase III trials, high-dose
chemotherapy should not be used in the adjuvant treatment
of breat cancer, apart from in randomized studies.
18
Taking a chance on life: How people decide
Given the toxicity and risks of HDC, and the fact that the
research findings are still equivocal, why do doctors
recommend it and younger women continue to decide on this
treatment in such large numbers? The simple answer is that
we don't base our choices solely on science, on proof of a
treatment, or lack of proof. Breast cancer patient Bill
Sherman put it this way:
How do we "know" anything we do will save our life? I don't
think we do. We gather as much information as possible and
make a "leap of faith" and hope/pray we made the right
decision that will be beneficial for us. I have learned
there are no right answers that apply to all of us and
although we all have breast cancer, it is still very much
an individual disease and the responsibility for how we
attack it is very much an individual decision. The bottom
line: I have to do what I decide is best for me with no
guarantees of the outcome.
A provocative study conducted at a London hospital, published
in the British Medical Journal in 1990, compared
attitudes about chemotherapy choices among cancer patients,
doctors and nurses, and the general public. When asked if
they would undergo a hypothetical aggressive chemotherapy
treatment, given a relatively low percentage chance of cure,
of prolonging life or of palliation of symptoms, the study,
even when repeated, found that health professionals and the
general public felt they would require a 50 percent chance of
cure to undergo the treatment, while many cancer patients were
willing to undergo treatment for a one percent chance of cure.
Cancer patients said they would undergo treatment if it might
give them one more year of life, while health professionals
and the general public said it would only be worthwhile if
it conferred two to five years of extended life. Finally,
patients said they'd risk the treatment for only a 10 percent
chance at palliation of symptoms, while health professionals
and the public said that they'd require 75 percent chance of
palliation. "Patients with cancer are much more likely to
opt for radical treatment with minimal chance of benefit
than people who do not have cancer, including medical and
nursing professionals."19
A 1995 mail survey by the Soper Research firm, jointly
sponsored by the National Alliance of Breast Cancer
Organizations, Y-Me Breast Cancer Organization of Chicago
and the Susan G. Komen Foundation, asked 1,500 women with
metastatic breast cancer about their treatment choices. Of
the 256 women who responded, over half said that it was
they, not their doctors, who took the lead in selecting
treatment. More than three quarters said that side effects
and quality-of-life issues were far less important than tumor
response to treatment. And nearly half felt that the main
encouragement of chemotherapy was the preservation of hope.
"This came as a surprise to many of us, who expected some
desire for balance between aggressive therapy and quality
of life," said Michelle Melin, Director of Patient Services
for Y-ME. "But we found many women willing to pursue very
aggressive therapy continuously until there were no more options."
20
It is obvious that both doctors and patients pay attention
to anecdotal information along the way, even though, as
everyone knows, your second cousin Mabel's friend's case
is of no statistical value in predicting your own treatment
outcome. If you know someone with metastatic breast cancer
in long-term remission following HDC, this is likely to
color your decision. Conversely, if someone you know has
died or been disabled from the treatment, this is bound to
make you wary. Dr. John Winberg, of the Foundation for
Informed Medical Decision-Making, puts it this way:
There is a lot of raw information out there that simply is
almost all case reports of individual patients, and in the
epidemiologic literature case reports get the lowest grade,
they do not have a balanced statistical evaluation.... So the
idea basically is to inform the patient in detail about the
and at the same time to make it clear that the decision
ultimately depends on the patient's own view of the
situation, the patient's own preferences. There is no single
right answer which the doctor can prescribe.
The doctor who recommends high-dose chemotherapy to you may
well have known a few patients who've had excellent results,
with no apparent or minimal lasting side effects. The hope
is that the remissions enjoyed by up to 20 percent of
patients receiving the treatment will prove to be very
long-lasting. To many younger, otherwise healthy patients,
this treatment seems like a risk well worth taking. One
caution, however: Physicians associated with a bone-marrow
or stem-cell transplant program may not be the most objective
or unbiased parties for you to consult in evaluating the
advisability of going this route. Doctors are human, too,
and it's only human nature to believe in the treatment they
offer patients. And medicine, let's not forget, is becoming
more and more a bottom line driven business. As always, it's
wise to pursue an objective second option from an oncologist unaffiliated with a transplant program before making your
decision.
Examining the way people make treatment decisions, and even
the nature of hope itself, may shed some light on why people
decide as they do and how you can find your way to your own
best decision. Sound medical research is one important basis
for our decisions, but it is far from the only factor we take
into account when making our choices. Cancer researchers,
physicians and patients often have radically different
perspectives, as the two studies cited above suggest.
Michael Lerner, director of Commonweal, a California health
and environmental research institute, and cofounder of
Commonweal's Cancer Help program, has been studying medical
decision-making his whole professional life, and discusses
it at length in the preface of his book Choices in Healing:
Cancer researchers, like all scientists, often do their work
best by a constant process of doubting whether promising
results from a new study are actually correct or not. That
healthy process of doubt leads them to check and recheck
every study. They have nothing to lose and everything to
gain by living in a research culture that emphasizes the
primacy of doubt. Their goal is to contribute to the
formulation of lasting true statements about the biomedical
nature and treatment of cancer.
People with cancer are fundamentally in a different
situation. To begin with, the time perspective of cancer
patients is different. They are more interested than cancer researchers in treatment possibilities that offer some hope
during the time defined by their particular disease.
21
By analogy, as Lerner points out, the cancer patient is
rather like a government policy maker faced with a national
emergency, say an environmental crisis. She must make an
immediate decision on the basis of incomplete information
and uncertain outcomes. Her scientific advisors have an
important role to play--they must tell her what is known
about the crisis, what is not known, what would clearly
lead to disaster in the face of current knowledge, and what
risk levels may be involved with other courses of action.
"The policy maker then decides on a course of action based
on considerations that are often entirely extraneous to the
scientific argument," Lerner points out. "The policy maker
decides for the nation just as the cancer patient must
decide for himself."
Reflections on treatment choices
Cancer patients sometimes talk about an inner acquiescence
to treatment, a combination of acceptance, resignation and
hopefulness that enables them to withstand the side effects
and uncertainty that go along with chemotherapy. The choices
made for or against HDC, with its quality of being a high
stakes gamble, only magnify the sensitive, personal nature
of every cancer patient's choice of whether or not to seek
treatment.
When all was said and done, most of the people I interviewed
felt they had made the best decisions for themselves, at
the time--whatever their choices had been, and whatever the
outcome. Over and over again, they emphasized the importance
of the following factors:
-
Getting all the relevant information.
-
Understanding the treatment goals and process as fully as
possible.
-
Considering the risks and benefits of treatment in relation
to the possible outcomes, including a full awareness of
potential side effects.
-
Gathering other medical opinions.
-
Talking with other patients, and spouse or partner.
-
Developing a sense of real trust in the treatment team,
particularly in the primary oncologist.
-
Then turning inward to make the best decision they could.
A certain empowerment, psychologically beneficial in itself,
is inherent in this kind of decision-making process. It's
altogether possible, of course, that people rationalize
their decisions, whatever they are. Having no regrets is
important for emotional well-being, but for the people I
interviewed, this seemed to depend far more on having gone
through a reasonable decision-making process than on whether
or not the outcome was the one desired.
Monica Driver, a high-risk primary breast cancer patient, at
first agreed to HDC, and cited the reasons for her choice:
Factors that influenced my decision? The notion of "hit it
hard before it becomes resistant" made sense to me (some
old biologist-type training there) and to my husband. My
husband and I agreed with Susan Love's notion that a research
protocol can be a good way to get treatment. The local MDs
were enthusiastic about the particular study I was being
offered. Obviously, much of this was personal and specific
to our own situation. But that's how I/we decided.
After her stem cells were harvested and her induction
chemotherapy was underway, Monica began to have doubts,
and decided to consult a psychiatrist who had worked with
many breast cancer patients. Monica explored her feelings:
For a long time the most pressing argument for going forward
with HDC, other than to stay alive for my family, was to
psychologically avoid any "What ifs" or "If onlys" should
cancer return. I could comfortably say, "Well, I did
everything I could to lick the beast and it was just not
meant to be." This does make some sense, but it seems a
backdoor means of making a decision.
Do I do the practical, expected thing and try to possibly
prolong my life via HDC while both risking long-term side
effects and giving up a number of months for recovery, or
do I kick over the traces and live to the fullest now while
I feel physically able to do so? She (the psychiatrist)
described this as living with joie de vivre. I have always
been the practical caregiver type, thinking of everyone
before myself. Now that I have accepted the fact that my
life may not be open-ended, I feel like kicking over the
traces and really letting my hair down (that doesn't mean
a whole lot as I only have half an inch to let down, but you
know what I mean). She did not help with the decision, but
I felt better for having discussed it and for being
understood. It was also the first time that I had admitted,
even to myself, to a basically selfish desire to live fully
in what time I have left. I think if I were younger, had
young children, or felt sicker, this would be an easier
decision. I don't look forward to the HDC/SCT itself, but
that is not what holds me back. It is the loss of time and
the possible long-term quality-of-life problems. When I
read about others who go through HDC/SCT and then have
recurrences so soon afterwards, I falter.
It wasn't easy to maintain her decision to forego the HDC
in favor of conventional chemotherapy. Monica experienced a
great deal of pressure from her physicians:
It is hard to buck the tide, go against the advice of
multiple doctors, and to decide something which "might"
shorten your life. The doctors even attempt to lay guilt
trips on you. When I told the first oncologist that I was
hesitating (she strongly advised HDC/SCT), she said, "Well,
if you could see the rapidity with which your cells are
dividing you wouldn't hesitate for a minute." She said this
in front of my husband, which added to the pressure on me
because then he wanted me to do the HDC and I felt guilty
not to be treated more aggressively for "his" sake. This
whole thing is horrible. Doctors at BMT centers spend hours
with you, often 3 to 4 hours with more than one doctor at a
time--where else would a doctor spend so much time with you?
It can only mean that they want and need you in their unit.
Ultimately, her husband fully supported her decision, and
Monica went on to seek two courses of intensive
chemotherapy as a substitute for the HDC. She is grateful
for the fact that unrelated health concerns which made it
impossible for her to take the most common drug used for
HDC caused her to research the issues more thoroughly than
she might have.
If I had not had to shop around for someone who would
treat me off study, I might have been swept into HDC after
4 rounds of CA and not had time to explore not only my
options, but my own heart.
Monica has found a way to live comfortably with her choice,
and even to redefine courage, as in this message to another
woman who was wrestling with the same decision:
One thing I think you should know, and that is that the
opposite decision can be made out of love also. Out of
love you can decide not to fight further. Everyone is
different, and clinging to the last vestige of life is
not always right. You are not a hero just because you
fight against all odds. Don't for a minute think that
if you decide not to go forward with the most aggressive
treatment that you are any less a hero.
As the husband of a Stage IV breast cancer patient, Glenn
Clabo thought a great deal about his wife having chosen HDC.
Following her decision, he wrote:
I've read the theories, opinions, thoughts and feelings
about amount versus success. I'm not comfortable with the
less may be better attitude. I'm too scared to say more
is better....I defer to the doc and Barb's wishes. She's
my love, but it's her life. I guess this comes down to
Barb's wish to do the most she can while healthy enough
to make it through. I have my concerns with all the
long-term possibilities, including...what if nothing is
done? She has put her head down and said, let's give it
hell. I'll continue to pass the info and support her
through whatever she decides to do.
After his wife had undergone the treatment and was
recovering well, Glenn found a discussion on the pros
and cons of HDC on the Breast Cancer Listserv agonizing
to read:
For those that question the cost and success of this....
Don't you realize without focus there is no hope? Without
hope, what's next? Does someone like Barb wait and take
her chances that she'll be here if this is proven years
from now? What else can her decision be based on but hope?
The desire to live...
Breast cancer activist Karen Gray, who participated as a
patient-advocate in the preparation of the Patient
Reference Guide of the ECRI meta-analysis, responded:
Hope is something that anyone can have whatever the choice.
It isn't limited to those who have HDC. Hope can always be
a part of our lives because it isn't dependent on statistics
at all. It is a state of mind entirely independent of one's
condition in life. And if you need focus you only need know
that there are always a residual few who end up doing well
despite a grim prognosis. There are always the unusual cases
to focus on whether they are taken as spontaneous remissions,
miracles or whatever. They can serve us all as life-jackets
so we don't sink into an ocean of depression.
I know a number of women who choose standard intensive
therapies and there is no difference between their being
hopeful and those who did HDC being hopeful. Both know
they're playing at a game table where they don't control
the spin of the wheel and time alone will show the results.
Hope is not a matter of rationality. It is a matter of inner
affirmation of a future where survival and health remains one
possibility--however remote--until death closes the door to all
possibilities except itself.
Shari Kahane, also a high-risk patient, detailed the kind
of questions she had asked herself in making her decision
about whether or not to undergo HDC:
The decision whether or not to have high-dose is a very
personal one that only the person involved, with the help
of his or her family, can make. There are many difficult
aspects to this decision. First, do I want to take the
risk of possibly dying from the treatment? Second, what
is the possible benefit of this procedure? In some cases
it is not known yet what the long-term benefits will be.
Third, which chemo regimen might be most effective?
Fourth, if I decide to do this, where should I do it?
Where are the survival numbers the best? Fifth, what are
the long-term side effects and am I willing to accept
them?
For some women, high-dose is not the right choice. They
may not have tumors that respond well to chemo or they
may be too uncomfortable with the risks of such aggressive
treatment. I believe it is an immensely personal choice
that has to be made carefully and under no pressure from
either the treating physician or the patient's family. I
can only relate my own experience. When faced with a very
poor prognosis that no one disputed, I chose high-dose
because I had two young children. If I died during the
procedure I wanted them to know that I had done what felt
right to me. I do have permanent side effects of nerve
damage to my hands and feet and my white blood cell count
remains very low. I will never have the energy I used to
have, and still have other lingering effects as well. My
own personal belief was that the "big guns" were right for
me but may not be so for everyone. Like anything else in
life, one has to weigh the potential positives and
negatives, explore all options, be as informed as possible
and then make the decision.
Jacque Fisher, who elected HDC after a regional
recurrence was followed by a pleural effusion, came
to see her own decision-making process this way:
Through all of this there have been a lot of woulda,
shoulda, coulda's...those will drive you crazy. I have
gone through all of the stages of denial, acceptance,
anger...fear, etc. What I have tried to do is investigate
my alternatives, choose treatment, place faith in my
judgment, my doctors and God, and then turn it over to
them! I try to never look back and rethink once I have
chosen my path. I aggressively fight the disease and any
kind of "acting sick." Even when I am in a "down"
period...I am convinced that all is going well...only
looking back do I see how weak I was.
Scott Kitterman encouraged his wife, Mary, to undergo HDC
as her best choice, although they both knew that there was
little chance of long-term remission:
I asked Mary if she'd rather bunt and maximize her chance
of getting on first base or swing hard and try and knock
one out of the park knowing that increased her risk of
striking out. She didn't even hesitate before saying knock
one out of the park.
For Barb Pender, too, it was not the outcome that dictated
whether or not she felt at ease with her treatment choice.
I am still here three years later--not cancer-free, mind you
(it did return within the year after my second transplant),
but I am still here and that is what is important to me.
The BMT bought me time--time to see my son reach sixteen
this year, time for my grandson to get a little older to
attempt to understand illness and death, and time for my
three-year-old granddaughter to know I exist. Others might
say that my BMT was not successful because of the cancer
returning but they are wrong! Every procedure that I
undertake is a success to me by virtue that I am still
alive. But please keep in mind that this is my personal
experience and not everyone has the same experience. I had
heard of the good stories and of the bad stories--I could
only pray that mine fell somewhere in the middle and, to
my surprise, it was better than I had hoped.
Not everyone is as sanguine, however, looking back. As
his wife, Ginger, lost ground, Bob Crisp reflected on
the state of cancer research with some bitterness:
Everyone wants to think they are taking an aggressive
approach to cancer and that they can handle it. Ginger's
had four surgeries, extensive radiation, several different
chemo regimens, a HDC/SCR and is about to have some more
radiation. The treatments have certainly been brutal and
difficult. The cancer continues. Is it possible to
overtreat cancer? Looking back, the answer for me is yes.
We don't need to be fighting harder; we need to be
fighting smarter. After our twenty-five-year and $37
billion "war" on cancer we have: 1) 13 percent increase
in cancer incidence, 2) 7 percent increase in death rate,
and 3) the five-year survival is virtually unchanged. I
still contend that we can't leave the research to the
isolated medical community which has a proven failure
record. It is time for new paradigms, starting with
multi-disciplinary research teams.
As a high-risk primary breast cancer patient, Bonnie
Gelbwasser continues to feel that the choices she made
were right for her:
At diagnosis in early December 1993, I was told that the
five-year survival rate for women with inflammatory breast
cancer was 50 percent. However, my doctors also stressed at
that time that with aggressive treatment and with the
strides in medical research and care, I could hope to beat
those odds.
So my hope was to get five or more years of life. The head
of the Bone Marrow Transplant Unit at the hospital was
adamant that I not view the ABMT as a cure, but rather as
a chance for a longer life. That was perfectly acceptable
to me. No one promised me the moon.
Sue Tokuyama felt much the same way about her HDC, but
would have handled it differently on an emotional level:
Do I think the HDC/ABMT was worth it? I don't know. I just
needed to do the most reasonable thing at the time, with
as much intelligence as I could muster. It seemed like the
best thing they had to offer. A few people on the list have
flown through the process with far more grace and panache
than me. My experience would be better described as an
angry, awkward, profane brawl, or blind shadow-boxing.
Would I do it again? Yes. In retrospect, I wish that I
had spent a couple of weeks prior to the experience
creating peace inside myself.
For what it's worth, a year out--Mr. Nasty seems to be gone,
or hiding well.
Whatever their treatment choices and situation, patients
appreciate support for making their own decisions. Joleene
Kolenburg was moved by her husband's support of her
treatment choices:
My husband got a call from a friend of his from the past
today who had heard about my mets to the lungs. He told
Jack that his wife had a breast removed recently, had one
treatment of chemo, lost her hair, and was sick and said,
"No more." Went to another doctor who said she did not need
any more chemo. It might kill any cancer cells, and it might
not. She might get mets and she might not. And if she took
chemo, she still might get mets. So she went back to work
and is doing fine. I guess he wanted to talk with Jack to
prove that yes, you could get mets even if you took chemo
(as I did) the first time around. He quoted scripture about
"the time to die," etc. Jack told him we believe that, too,
but Jo (me) was a fighter and wanted to do everything she
could to fight this thing, and he was with me 100 percent.
It was the first time that Jack had talked at length with
anyone about this and I was proud of him, and pleased that
he supported my decision when talking to his friend. Jack
told him that it was good that he (the friend) supported
his wife's decision, just as Jack did mine. "After all,
it is their life and their decision."
Kim Banks wrote of her tendency to regret treatment choices
later on:
Because of my recurrence I have sometimes regretted not
trying harder to take tamoxifen three years ago--I have a
history of migraine headaches and the tamoxifen caused
them to quadruple in intensity. Thinking back, I know now
that I made the right decision for me at the time. I don't
want to spend the rest of my life worrying rather than
living.
Something I'd like to add. Many breast cancer patients feel
pressured from family and friends, as well as themselves,
to choose the most aggressive treatment. Often they don't
really know what it is like to go through those treatments,
nor do they understand the difference in outcomes (in many
cases, negligible). I guess it's another situation where we
must know ourselves and be true to ourselves. Make the
decisions for our own reasons and derive comfort in knowing
that we've chosen what is best for us.
