Abstract Background. Surgery has been regarded as the standard treatment for patients with non-small cell lung cancer in the early stage, while radiotherapy has become an effective alternative for medically inoperable patients and those who refuse surgery. Methods. We reviewed the records of 31 patients with stage I–II non-small cell lung cancer treated by radiotherapy between 1980 and 1997. There were 15 patients in stage I and 16 in stage II. The variables analyzed for influence on cause-specific survival and loco-regional control were: age, performance status, clinical stage, tumor size, tumor site, radiation field, radiation dose, and combination with chemotherapy. Results. The overall and cause-specific 1-, 2-, 3-, and 5-years survival rates were 71% and 77%; 63% and 73%; 34% and 48%; and 17% and 32%, respectively. Five-year survival rate for patients with peripheral tumor in the lung was 72%, with 70% loco-regional control, while the 5-year survival rate of patients whose tumor originated in the central region was 20%, with 25% loco-regional control. These differences had marginal significance on univariate analysis (P = 0.07), but only tumor site (central vs peripheral ) showed marginal significant influence on cause-specific survival (P = 0.08) and loco-regional control (P = 0.07) on multivariate analysis. There were no fatal complications, including radiation-induced myelopathy. Conclusion. The present series showed satisfactory results with definitive radiotherapy for patients with medically inoperable stage I–II non-small cell lung cancer, with results similar to those in recent reports of radiotherapy. The only significant variable was that patients with peripheral tumors had a better prognosis than patients with central tumors.
