To evaluate the effect of radiation therapy in nonsmall cell lung cancer stage IIIB, we analyzed the 23 patients diagnosed NSCLC IIIB and treated curatively with radiation therapy between September 1989 and March 1993 at the department of therapeutic radiology, Chungnam National University Hospital, retrospectively. The actuarial 1 year survival rate was 39.2%, 2 year survival rate was 2.3%, and median survival time was 10 months. The difference of survival rates by performance status, response to radiotherapy, T stage, N stage, tumor size, age, pathologic cell type, combination with chemotherapy was not statistically significant. To increase the survival time and rate of the patients with NSCLC IIIB, further study for adequate radiation fractionation and dose, combination with chemoherapy and surgery will be needed.
