Abstract
From records of 4, 931 cases of lung cancer during 1975-77, clinical statistical analysis according to histological type was performed. Epidermoid carcinoma accounted 46.6% of male cases and 18.8% of female cases, while adenocarcinoma was the histologic type in 61.2% of female cases and 30.3% of male cases. 5-year survival rates were 14.4%, 14.4%, 11.9%, 5.4%, 1.3% for epidermoid carcinoma, adenocarcinoma, large cell carcinoma, small cell carcinoma intermediate cell type and oat cell type, respectively cell carcinoma.
In adenocarcinoma 32.9% were in stage Ia, and showed 52.1% operability overall and 43.0% curative operability. In small cell carcinoma intermediate cell type and oat cell groups 75%, 79.8% of cases were in stage III+IV respectively. The operability of oat cell carcinoma was 15.2%, 72.2% underwent radiation and 84.8% underwent chemotherapy.
