CHANGING CANCER CARE FROM WITHIN
PROMISING AS OUR DRUG RESEARCH was, I had to work at the same time on institutional changes to improve outcomes. The complete answer, I knew, was not going to come in the form of a pill. The old treatment models were not working fast enough, and new scientific insights, while promising, simply were not being translated as rapidly as hoped into better therapies. We had to enlist more resources, and different types of resources, to really make significant improvements in how the patients did and how the patients felt. As I had found at Columbia-Presbyterian Hospital, clinical cancer care operated in a somewhat insular world. I decided to take a calculated gamble and replace Ted Beattie, the physician in chief overseeing Memorial Hospital. Though a superb cancer surgeon, he had allowed the hospital’s clinical approach to become overly dependent on surgery as the principal method for dealing with the broad range of cancers. I felt we needed a clinical leader who could expand our programs in medical oncology and radiotherapy—that is, to provide excellence in all the areas of cancer care.
Surgery is very important and can be highly effective in cases where a tumor can be removed before it has metastasized or, at the least, before it has metastasized widely. Good candidates for surgical cures represented, however, only about a third of the patients who came to Memorial in the early 1980s.
The problem was that the emphasis on “heavy cutting” had pushed other treatments, such as chemotherapy, radiation therapy, or immunotherapy, into the background. In Beattie’s view, you turned to drugs or radiation only if the doctors had been unable to control or remove the cancer with surgery. I believe he saw the use of chemotherapy drugs, immunological approaches, and radiotherapy as signs of failure, not supplementary measures to help patients live longer.
I appreciated the importance of surgery, of course, but, because I had already been working on a pioneering targeted therapy drug, I believed strongly that it was time to bring more tools to bear on what was still a relatively poor record in improving the lives of cancer patients. There had been some advances in developing chemotherapy “cocktails,” that is, treatments with mixtures of drugs designed to hit different targets in cancer cells.
This combination therapy was producing prolonged remissions in about 80 percent of children with acute lymphoblastic leukemia, for example, but nothing as dramatic in adults. Researchers had developed the first clinically useful biomarker test for a cancer, in this case a means of detecting prostate cancer (with the prostate-specific antigen, or PSA, test), often well before the patient developed symptoms. Still, we were not doing well enough clinically on those patients with proven cancers.
