Determining genetic signature of lung tumors can help guide treatment

The first U.S. clinical trial using genetic screening to identify lung tumors likely to respond to targeted therapies supports the use of those drugs as first-line treatment rather than after standard chemotherapy has failed. While the study led by Massachusetts General Hospital Cancer Center investigators found that upfront gefitinib (Iressa) treatment considerably improved the outcomes for non-small-cell-lung-cancer (NSCLC), additional research is required before such a strategy can be used for routine treatment planning. The report appears in the May 20 Journal of Clinical Oncology.
