A clinical statistical analysis of 4,931 lung cancer cases in Japan according to histological type--field study results. A report from the Japanese Joint Committee of Lung Cancer Associated with the TNM System of Clinical Classification (UICC).
From records of 4,931 cases of lung cancer during the period 1975-1977, a clinical statistical analysis according to histological type was performed. Epidermoid carcinoma accounted for 46.6% of male cases and 18.8% of female cases, while adenocarcinoma was the histological type in 61.2% of female cases and 30.3% of male cases. Five-year survival rates were 14.4%, 14.4%, 11.9%, 5.4% and 1.3% for epidermoid carcinoma, adenocarcinoma, large cell carcinoma, and small cell carcinoma of the intermediate cell type and oat cell type, respectively. Of the adenocarcinoma cases, 32.9% were in Stage Ia, and 52.1% showed overall operability and 43.0% curative operability. For small cell carcinoma of the intermediate cell type and oat cell type, 75% and 79% of cases were in Stages III and IV, respectively. The operability of oat cell carcinoma was 15.2%; 72.2% underwent radiation, and 84.8% underwent chemotherapy.
