Drug
treatment of cancer: No progress in three decades. The
March
22, 2004 issue of
Fortune (PDF)
has an excellent article which shows that there has been no real progress
in the treatment of the
most common forms of cancer. Entitled
"War on Cancer: Why the New Drugs Disappoint," the article cites
NCI data showing that US cancer mortality
rates have increased and age-adjusted cancer
mortality rates in
response to treatment
have not improved in several decades, despite the introduction of many
new drugs.
The article indicts the "cancer investigator"
culture, which prizes the exhaustive examination of trivial
hypotheses, while eschewing support of "cancer
discoverer" type research, attempting to create entirely new
paradigms of cancer treatment. In the words
of the author, a large and broad group of "experts offered
testimony that, when taken together, describes
a dysfunctional 'cancer culture' -- a groupthink that pushes
tens of thousands of physicians and scientists
toward the goal of finding the tiniest improvements in
treatment rather than genuine breakthroughs;
that ... rewards academic achievement and publication over all
else." The author goes on to note that
"investigators rely on models that are consistently lousy at predicting
success -- to the point where hundreds of
cancer drugs are thrust into the pipeline, and many are approved by
the FDA, even though their proven 'activity'
has little to do with curing cancer." The article specifically
condemns the acceptance of models for cancer
treatment (e.g. mouse models, established cell line models,
molecular mechanisms) which have been of limited
relevance to drug activity in real human cancer.
The above are the precise points which I have
been making in publications which date back more than 20
years. The great failing of academic
clinical oncology in the area of cell culture drug resistance testing with
cell death endpoints is not that clinical
oncology has failed to embrace the technology, but that academic
clinical oncology has refused even to consider
and test the ability of the technology to improve cancer
treatment in clinical trials, while carrying
out hundreds of clinical trials of one-size-fits-all therapy in tens of
thousands of patients which tested trivial
hypotheses and produced no progress.
