Abstract
The results of 4, 931 lung cancer cases treated during 1970-72, were examined to evaluate the factors influencing the prognosis of lung cancer.
The background factors examined included T-factor, N-factor, M-factor, TNfactor, clinical stage, histological type, age and sex. The prognosis was also examined according to method of treatment. The five year survival rate in the curative resection only group was 42.6%, in curative resection + chemotherapy, 52.1%, in curative resection + chemotherapy + immunotherapy 54.8% and in curative resection + irradiation+ chemotherapy 49.4%.
The improvement of results of 5-year survival rate in cases with lung cancer by multi-modality were expected.
These results suggest improved 5-year survival by multimodality treatment.
