Editor’s Note: Quality-of-life implications of variations in
practice patterns |
Direct-to-consumer television
ads for pharmaceuticals are
supposed to target end users,
but the truth of the matter is that any
unassuming physician just trying to
unwind in front of the tube is also a
captive audience for these monotonous,
hammering messages.
So it was this past Saturday that
with my newly born son, Joseph Jacob
(Neilly) Love, perched on my lap, I tried
to enjoy the University of Miami’s Titus
Pullo-like football dismembering of the
University of Virginia, while being buried
by a video avalanche of PDE5 inhibitor-
inspired “educational” ads related to
erectile dysfunction.
Fortunately, TiVo® was on our side,
and as we zipped through these and
other mindless commercials without losing
our focus on the U’s ground game, I
was struck, even in their rapid passing,
by the sheer number of messages openly
promoting what used to be a very private
matter.
The integration of the “ED” concept
into the Western psyche over the last
few years is an awe-inspiring testimonial
to the power of marketing, and it seems
as though we have almost reached the
point of accepting erectile dysfunction
as just another “parts” defect that may
require medical attention. But all ED is
not created equal, and nowhere is this
more apparent than with the currently
accepted clinical management options
for men with prostate cancer.
One of the great challenges of being
a physician is utilizing therapies with
significant side effects and toxicities, and
in prostate cancer, we encounter perhaps
the most provocative and personal set of
downsides that exist in current cancer
and maybe even noncancer medicine.
For localized disease, the patient
experience is very different for men who
have their prostates removed surgically
compared to those who receive some
variant of radiation therapy. During this
very stressful waiting game, patients who
choose surgery almost universally experience
complete postoperative ED, and
men lucky enough to have nerve-sparing
procedures wait nervously for many
months or longer to see whether functional
recovery occurs.
Patients who sit under the beam or
seed of their friendly radiation oncologist
experience a reverse waiting process
as gradual vascular compromise in
some or most patients eventually results
in ED.
The story is even more complicated
when systemic therapy enters the equation.
Chemical castration results in a
highly toxic internal milieu with complex
sequelae including ED and loss of libido,
diminished muscle and bone mass, and
uncomfortable vasomotor symptoms.
Bicalutamide monotherapy, which
does not result in many of these problems
but does cause gynecomastia, is a
largely ignored therapeutic alternative,
apparently because the existing clinical
research database on this fascinating
agent has not sufficiently impressed
clinical investigators or the FDA to make
it available to patients.
With this as background, let us consider
the findings from our CME group’s
first national prostate cancer patterns of
care study. With the expert input of Drs
Adam Dicker and Mark Soloway, we
designed a case-based telephone survey
focused on intermediate and high-risk
localized disease, PSA relapse and metastatic
disease. (Our 2006 survey will be
expanded to include low-risk localized
disease.) In September 2005, we contracted
the independent market research
firm ReedHaldyMcIntosh to conduct
this study, which randomly recruited 50
radiation oncologists and 100 urologists
practicing in the United States.
As with our prior Patterns of Care
studies in breast cancer and colorectal
cancer (www.PatternsofCare.com),
considerable heterogeneity is evident in
the treatment recommendations made to
men with prostate cancer.
What is unique about this variability
is the profound difference in quality-oflife
endpoints that exists with prostate
cancer treatments compared to treatments
for other tumors.
The findings obtained from this survey
are probably not that surprising to
physicians, who on a daily basis confront
practice situations in which the
available clinical research database does
not clearly delineate the most favorable
therapeutic option.
However, I predict that any patient
or layperson seeing these data will take
a deep breath or gasp and then strongly
consider the importance of obtaining a
second or third opinion when confronting
this disease.
