本文研究了17例手术切除的周边型小细胞未分化肺癌。肺瘤大小为0.9～3.5cm,平均为2.1cm。其中男10例,年龄为40～75岁,平均58岁;女7例,年龄49～71岁,平均82岁。均为嗜烟者。所有病例无临床症状,也无任何肿瘤转移的迹象.肿瘤皆系偶然发现。周边型小细胞未分化肺癌由中间型和梭形瘤细胞构成.7例肿瘤组织中含有燕麦细胞灶,无鳞状细胞和腺样分化。肿瘤细胞浆少,染色质呈细颗粒状,多
This paper studied 17 cases of peripheral small cell undifferentiated lung cancer. The tumor size was 0.9-3.5 cm with an average of 2.1 cm. Among them, there were 10 males, aged 40-75 years, with an average age of 58 years; females 7 were aged 49-71 years with an average age of 82 years. All are smokers. All cases had no clinical symptoms and no signs of tumor metastasis. Tumors were accidentally discovered. Peripheral small cell undifferentiated lung cancer consists of intermediate and spindle-shaped tumor cells. Seven cases of tumor tissue contained oat cell foci without squamous cells and adenoid differentiation. The cytoplasm of the tumor is small and the chromatin is finely granular.
