An experimental lung cancer vaccine does not extend life overall, but may still benefit some people, leading the U.S. Food and Drug Administration (FDA) to approve further trials for these groups. These findings were reported at the 2013 European Cancer Congress in Amsterdam, Netherlands. Called belagenpumatucel-L, the vaccine is based on non-small cell lung cancer (NSCLC) cell lines and boosts the immune response. The phase III clinical trial included 532 people with NSCLC who had already undergone chemotherapy and the vaccine benefitted two subgroups. People who had previously been treated with radiation lived longer (40 mo with radiation vs 10 mo without radiation), as did people whose lung cancers were not adenocarcinomas (20 mo for nonadenocarcinomas vs 12 mo for adenocarcinomas).
