The impact on survival by adjuvant chemotherapy and radiation therapy in stage II non-small-cell lung cancer.
Forty-nine consecutive patients with pathologic Stage II non-small-cell lung cancer treated over a 15-year period were retrospectively reviewed. The treatment strategy evolved during the period of review. Early patients were treated with surgery alone (S); subsequent patients were treated with adjuvant radiation therapy (SR); and more recent patients were treated with postoperative chemotherapy and radiation therapy (SRC). Fifteen patients received S alone, 10 patients received SR, and 24 patients received SRC. The median survival time (MST) of all 49 patients was 20 months, and the estimated 5-year survival was 25%. The MST of patients in each of the three treatment arms was S-6 months; SR-19 months; and SRC-25 months. The majority of patients died from systemic relapses or second primary lung cancers. The addition of adjuvant therapy (SR, SRC) significantly improved the MST of patients compared to surgery alone (S). The overall survival of patients did not change between treatment arms.
