我科自1963年3月～84年8月经痰液癌细胞检查的200例原发性肺癌(以下简称肺癌)均经病理切片证实,其中117例细胞学阳性。另外,获得65例肺癌术后随访。现分析如下: 本组200例肺癌中,男性164例,女性36例,发病年龄最小的19岁,最大的89岁。发病高峰为41～60岁,共139例。 (一)肺癌发生部位与细胞学阳性率的关系:200例中,双肺发病率较接近(右;86例;左82例), In our department, 200 cases of primary lung cancer (hereinafter referred to as lung cancer) that were examined by sputum cancer cells from March 1963 to August 84 were all confirmed by pathological examination, of which 117 were positive for cytology. In addition, 65 patients with lung cancer were followed up. The analysis is as follows: In this group of 200 lung cancers, 164 were males and 36 were females. The youngest age was 19 years old and the oldest was 89 years old. The peak incidence of 41 to 60 years old, a total of 139 cases. (1) The relationship between the site of lung cancer and the positive rate of cytology: In 200 cases, the incidence of lungs was relatively close (right; 86 cases; left 82 cases),
