54例小细胞肺癌的组织学亚型根据1977年WHO分类,燕麦细胞型42例,中间细胞型癌7例,混合燕麦细胞癌型5例,所有病例接受同样的联合化疗,用或不用放疗,燕麦细胞癌有效率(CR+PR)69％,中间细胞癌型+混合细胞癌型有效率(PR)50％。燕麦细胞癌的有效率与中间细胞型+混合细胞型有效率相比有显著差异P<0.01。获得完全缓解的15例燕麦细胞癌中6例长期无病生存3～10年,仅1例是混合细胞型生存29个月。燕麦细胞癌中数生存比中间细胞型+混合燕麦细胞型的中数生存有显著差异(12月对5月,P<0.01)
The histological subtypes of 54 cases of small cell lung cancer were classified according to the 1977 WHO classification, oat cell type 42 cases, intermediate cell type cancer 7 cases, and mixed oat cell type 5 cases. All cases received the same combination chemotherapy with or without radiotherapy. Oat cell carcinoma has an effective rate (CR+PR) of 69%, and intermediate cell carcinoma type+ mixed cell carcinoma type (PR) has 50%. The efficiency of Oat cell carcinoma was significantly different from that of intermediate cell type + mixed cell type P<0.01. Of the 15 cases of Oat cell carcinoma that achieved complete remission, 6 cases had long-term disease-free survival for 3 to 10 years, and only 1 case of mixed cell type survived for 29 months. The number of survival in Oat cell carcinoma was significantly different than the median survival of intermediate cell type + mixed Oat cell type (December to May, P<0.01)
