Radiotherapy for patients with primary cancer of the lung

Analysis of 137 patients with adenocarcinoma of the lung who were mainly treated by radiotherapy was performed. The 5-year survival rate was 19 % in stage I (15) and 20 % in stage II (14). Survival rate by histologic subtype in stage I or II was better in well differentiated cases than in poorly differentiated cases. Five 5-year survivors were all well differentiated adenocarcinoma cases and four were in stage I or II, one was in stage IV. From these results it was considered that in stage I or II well differentiated adenocarcinoma cases radical radiotherapy can be indicated. (author)
