The sections were stained with H.E., PAS-ab and Keratin, and compared with sections of 131 cases of lung cancer being confirmed beforehand from 1978～1984. Chinese cases showed epidermoid carcinoma 165 (male 146), adenocarcinoma 136(male 82), small cell carcinoma 29 (male 21), large cell carcinoma 19 (male 15) and the others 29 (male 27); Japanese cases were 59(50), 53(25), 3 (2), 11(10), 3(0) respectively. The cases under 40 years of age were 23(6.1%) in China, 3(2.3%)in Japan. Both of them have similar character of histology. But the incidence of lung cancer in youth is higher in China.展开更多
