The presence or absence of a protein in lung cancer cells could help doctors predict whether chemotherapy will help patients live longer after surgery, researchers say. In a study published in the Sept. 7 issue of the New England Journal of Medicine, they found that volunteers with undetectable levels of the protein ERCC1, which is important in repairing DNA, had a five-year survival rate of 47% when treated with the platinum-based class of chemotherapy drugs such as cisplatin.

Home DNA kits that claim to warn people of their risk of diseases ranging from cancer to osteoporosis offer little real guidance and are often misleading, according to a congressional report.

The citywide campaign, which appears to be unprecedented in its breadth, will target 400,000 men, women and teenagers, encouraging them to learn their HIV status through an oral swab that delivers results in 20 minutes.
