６３例住院期死亡的中晚期非小细胞肺癌（ＮＳＣＬＣ）分为化疗组３６例，非化疗组２７例。两组在性别、年龄、病理分型、入院时生活功能上条件相当，具有可比性。治疗结果：化疗组与非化疗组中位数生存期为１５．０对８．０月＊及１１．７对６．０月＊＊（Ｐ）＜０．０１、Ｐ＊＊＜０．０１，ｔ’法）。根据是否接受营养支持，进一步将６３例分为４组，各组生存期结果显示：化疗加营养支持组与非化疗组之间有显著意义的差异（Ｐ＊＜０．０５、Ｐ＊＊＜０．０５，Ｓｔｕｄｅｎｔ－Ｎｅｗｍａｎ－Ｋｅｕｌｓ法），其余组间比较均无显著意义差异。结论：患者生存期的延长是化疗加营养支持共同作用的结果。
Sixty-three in-patient deaths of advanced non-small cell lung cancer (NSCLC) were classified into chemotherapy group (n = 36) and non-chemotherapy group (n = 27). The two groups were comparable in terms of gender, age, pathological type, and functioning on admission. They were comparable. Treatment Outcomes: The median survival time for the chemotherapy and non-chemotherapy groups was 15.0 vs. 8.0 months and 11.7 vs. 6.0 months** (P)<0.01, P**<0.01 ,t’ method). Based on whether or not to receive nutritional support, 63 patients were further divided into 4 groups. The survival results in each group showed significant differences between chemotherapy plus nutritional support group and non-chemotherapy group (P*<0.05, P**< 0.05, Student-Newman-Keuls method), there was no significant difference between the other groups. Conclusion: The prolongation of the survival of patients is the result of the combined effect of chemotherapy and nutritional support.
