- <p>Colon cancer held at bay
- </p>
- <p> For decades the only true weapon against colon cancer has
- been surgery. If the scalpel could take out the entire tumor,
- the patient was cured; if not, the cancer recurred. But now, for
- the first time, researchers have developed a drug therapy that
- may reduce the high death rate from this form of cancer, which
- kills 53,500 Americans each year and is the third most common
- type of malignancy.
- </p>
- <p> In a series of studies coordinated by Dr. Charles Moertel
- of the Mayo Clinic in Rochester, Minn., researchers tested a
- combination of two drugs: 5-fluorouracil, a proven anticancer
- agent, and levamisole, a medication commonly used by
- veterinarians to clear worms from the intestines of animals.
- Included in the studies were some 1,700 cancer patients, most
- of whom had been operated on for Dukes' C colon cancer. In this
- stage of the cancer, the tumor has penetrated the bowel wall but
- has not spread to the rest of the body. The results of the first
- study, which appeared in this month's Journal of Clinical
- Oncology, showed that 49% of patients receiving the treatment
- were still alive after five years, in contrast to 37% of another
- group that did not receive the drugs. In a second and much
- larger study, which has yet to be published, the benefit from
- the drug therapy "at least matched" the results achieved in the
- first experiment, said Dr. Moertel.
- </p>
- <p> The researchers caution, however, that the drugs are not
- effective for patients with more severe colon cancer, in which
- the malignancy has already spread throughout the body. Nor have
- studies shown a benefit for those patients whose cancers were
- detected at an early stage. Still, Dr. Michael Friedman of the
- National Cancer Institute called this first success for drug
- therapy against colon cancer a "terrific intellectual
- breakthrough." The institute has alerted 35,000 cancer doctors
- across the country. And some experts are hopeful that the
- findings will lead to similar therapies for other cancers.
