胃肠道间质瘤32例的临床研究

Clinical research on 32 cases of gastrointestinal stromal tumor

目的 通过研究32例胃肠道间质瘤的临床病理特点,探讨胃肠道间质瘤的预后影响因素.方法 回顾性分析2007年5月-2013年4月接受手术治疗并经病理证实的32例胃肠道间质瘤的临床资料,统计学分析影响其预后的因素.结果 32例患者,2年总体生存率为85.3％,2年无进展生存率为79.2％.影响胃肠道间质瘤预后的因素包括：肿瘤大小、远处转移、核分裂像、NIH危险度分级.结论 NIH分级、远处转移是影响胃肠道间质瘤术后生存的危险因素.

Objective Analyzed 32 cases of gastrointestinal stromal tumors（GIST） patients,to analysis the clinical and pathological characteristics of gastrointestinal stromal tumors of the stomach and explore associated prognostic factors.Methods Thirty-two GIST patients confirmed pathologically were included from May,2007 to April,2013.Their clinical records were retrospectively analyzed.Results Of the 32 GIST patients,the overall survival （OS） is 85.3％ for the second year.The progression free survival （PFS） is 79.2％ for the second year,respectively.Univariate survival analysis showed that OS and PFS have significant association with tumor size,metastasis,mitotic index and NIH risk group.Conclusions Metastasis and NIH risk group both are potential prognostic factor for gastric GIST.
