A group of 154 limited small cell lung cancer patients was studied. 107 of them were treated with chemo- radiotherapy on tumor and mediastinum, 47 patients were treated with chemotherapy only. A significantly higher rate of complete remission and duration of the remission, longer survival time and lower rate of local relapses were found in the group treated with chemo- radiotherapy.
