We assessed the outcome in 65 patients with limited small cell lung cancer (SCLC) treated from 1980 through 1989 with combination chemotherapy and chest and cranial irradiation. Of the 65 patients, 32.3% (21/65) achieved a complete remission (CR) prior to radiation therapy; six additional cases achieved a CR after radiotherapy with an improvement of 10% in the incidence of CR. In our group, 8 patients were alive and free of disease at 30 months (12.3%). We think that a combination of local thoracic irradiation in SCLC limited disease plus chemotherapy yields more CR and improves survival, especially in the group of patients who obtained the CR after initial induction chemotherapy.
