03-06-2012 19:04 An experimental cancer drug successfully shrank tumors in patients with different kinds of cancer, including typically hard-to-treat lung cancers, according to a new study. Oncologists said the research was encouraging, but more study was needed to know whether the drug would prolong life for cancer patients. The study, led by Dr. Suzanne Topalian, was presented today at the Super Bowl of cancer professionals, a meeting of the American Society of Clinical Oncology, and published in the New England Journal of Medicine. In a small, early phase study, researchers used a drug targeting a portion of the body's immune system, a pathway called PD-1, which usually works to stop the body from fighting cancerous tumors. By shutting down the pathway, the drug stokes the body's immune system to fight tumor cells. Researchers gave the drug to nearly 240 patients with advancedmelanoma, colorectal, prostate, kidney and lung cancers. All the patients had tried up to five other treatments, which failed. After up to two years on the drug, tumors shrank in 26 of 94 patients with melanoma, nine of 33 patients with kidney cancer and 14 of 76 patients with lung cancer. For more on this story:
