PurposeTo investigate feasibility, toxicity, and efficacy of accelerated hyperfractionated radiation therapy and concurrent carboplastin/oral etoposide in elderly (> 70 years) patients with stage III non-small-cell lung cancer.Methods And MaterialsBetween January 1988 and June 1993, a total of 58 patients entered a phase II study. Carboplatin (400 mg/m(2)) was given intravenously on days 1 and 29, and etoposide (50 mg/m(2)) was given orally on days 1-21 and 29-42. Accelerated hyperfractionated radiotherapy was administered starting on day 1, with a total dose of 51 Gy in 34 fractions over 3.5 weeks.ResultsIn 55 evaluable patients, the complete response rate was 27% and the overall response rate was 65%. For the 55 patients, the median survival time was 10 months, and the 1-, 2-, and 5-year survival rates were 45%, 24%, and 9.1%, respectively. The median time until relapse was 8 months and the 1-, 2-, and 5-year relapse-free survival rates were 45%, 20%, and 9.1%, respectively. The median time to local recurrence was 14 months and the 5-year local control rate was 13%; the median time to distant metastasis was 18 months and the 5-year distant metastasis-free rate was 15%. Hematological, esophageal, and bronchopulmonary acute grade 3 or 4 toxicities were observed in 22%, 7%, and 4% of the patients, respectively. There was no grade 5 toxicity or late grade > or = 3 toxicity.ConclusionConcurrent accelerated hyperfractionated radiotherapy and carboplatin/oral etoposide produced relatively low and acceptable toxicity. The survival results appeared to be comparable to those obtained in nonelderly patients with stage III non-small-cell lung cancer treated by full-dose radiation.
