New Drugs Unleash Immune System to Attack Tumors
Lung, Skin, Kidney Tumors Shrink in Early-Stage Trials Two experimental drugs that recharge the body's immune system to seek out and attack tumors are showing promise for the treatment of certain advanced lung, skin, and kidney cancers. The drugs disable a molecular shield that tumors put up to block attacks from the immune system. In early-stage studies, the drugs shrank tumors in some people with certain types of lung, skin, and kidney cancers who had not been helped by other treatments. Researcher Julie Brahmer, MD, associate professor of oncology at Johns Hopkins Kimmel Cancer Center, tells WebMD that she is optimistic because "in some patients, tumors did not grow back even after treatment was stopped." "These patients had been through several types of therapy and were very ill," she says. It's too soon to say whether the drugs will extend lives and whether they are safe in the long run. A larger, longer study is planned to test that. But the early
