[The role of radiation therapy in the treatment of lung cancer].
An analysis of the effectiveness of radiotherapy was performed in 165 patients with non-small cell carcinoma of the lung who received more than 4500 cGy as a definitive treatment between April 1980 and March 1983 and survived longer than 2 months after the start of radiotherapy. Of patients with inoperable malignancy, 38.8% for stage II survived 3 years and 27.7% for stage III, while 4.1% of patients with stage IV disease were 2 year survivors. Median survivals of patients for each stage were 24.7, 18.7 and 5.9 months, respectively. As for further analysis of stage III, better results for year-survival rates and median survivals were observed in T1-2 N2 M0 than in T3 N0-1 M0. Based on these results, the role of radiotherapy for non-small cell lung cancer was discussed.
