A Genomic Strategy to Refine Prognosis in Early-Stage Non–Small-Cell Lung Cancer

Abstract
Clinical trials have indicated a benefit of adjuvant chemotherapy for patients with stage IB, II, or IIIA — but not stage IA — non–small-cell lung cancer (NSCLC). This classification scheme is probably an imprecise predictor of the prognosis of an individual patient. Indeed, approximately 25 percent of patients with stage IA disease have a recurrence after surgery, suggesting the need to identify patients in this subgroup for more effective therapy.
