title: [Treatments and diagnosis of lung cancer--field study results: report from japan lung cancer TNM classification committee].
abstract: The results of 4,931 lung cancer cases treated during 1970-72 were examined to evaluate the factors (especially N factors) influencing the prognosis of lung cancer. The background factors examined included T-factor, N-factor, M-factor, clinical stage, histological type, age and sex. The prognosis was also examined according to treatment method. The 5-year survival rate in the curative resection only group was 42.6%, in curative resection + chemotherapy 52.1%, and in curative resection + chemotherapy 52.1%, and 54.8%. The results suggest improved 5-year survival by multimodality treatment.
