Abstract

Purpose: A phase II study was conducted by the Southwest Oncology Group (SWOG) to assess the efficacy and toxicity of concurrent carboplatin, etoposide, and thoracic radiation (XRT) in a defined population of poor-risk patients with stage III non-small-cell lung cancer (NSCLC). Patients and Methods: Patients with stage III NSCLC were eligible if they were excluded from cisplatin-based protocols because of poor pulmonary or renal function, history of congestive heart failure, hearing loss, peripheral neuropathy, or weight loss. Carboplatin 200 mg/m2 daily intravenously days 1, 3, 29, and 31 and etoposide 50 mg/m2 daily intravenously days 1 through 4 and 29 through 32 were administered. Beginning day 1, XRT was delivered at 1.8 to 2.0 Gy daily to a total dose of 61 Gy. Results: Within a period of 1 year, 63 patients were registered and 60 were eligible. Patient characteristics were age 47 to 79 years, performance status 0 to 1 (82%) and 2 (18%), and stages IIIA (60%) and IIIB (40%) NSCLC. The most common grades 3 and 4 toxicities included leukopenia (50%), thrombocytopenia (23%), and esophagitis (15%). There were no treatment-related deaths. The overall confirmed response rate was 29%, and median overall survival was 13 months (95% confidence interval, 11 to 14 months). The 2-year survival rate was 21%. Conclusion: This chemoradiotherapy regimen is well tolerated in poor-risk patients and yields a median survival similar to that of good-risk patients who received cisplatin-based chemoradiotherapy. This chemoradiotherapy regimen will be compared with XRT alone in poor-risk patients with stage III NSCLC in a randomized phase III trial.
