胃癌根治术预后临床病理因素分析

Multivariate Analysis of Influnencing Survival after Radical Surgery for Gastric Cancer

回顾性分析了３９０例胃癌行根治性切除术后的病例，通过对临床病理指标的单因素和多因素Ｃｏｘ回归分析，研究诸因素影响预后的作用程度。结果：本组３－ＹＳＲ、５－ＹＳＲ分别为５５．４％、４０．３％，手术死亡率为３．６％。肿瘤浸润深度、淋巴结阳性数、肿瘤大小和根治程度是影响术后生存率的独立性因素。与预后相关性因素包括：年龄、组织类型、解剖部位和淋巴结转移程度。其它因素与预后无明显相关性。

This retrospective study of prognostic factors influencing the survival of 390 caces with gastric cancer after radical surgery was performed.The clinicopathologic factors was evaluated by univariate and multivariate of Cox regression.Results showed that 3 YSR and 5 YSR were 55.4% and 40.3%,the 30 day postoperative mortality was 3.6%,The depth of invasion,number of positive 1ymph nodes,size of tumour and operative curability were independent prognosis factors.Age,location of primary tumour,histologic differentiation and 1ymph nod metastasis showed some significance.0thers were not statistically associated with prognosis.
