胃肠道间质瘤预后因素分析

目的 探讨影响胃肠道间质肿瘤(GIST)预后的因素.方法 收集1999年11月至2006年12月于复旦大学附属华山医院住院手术治疗并经病理确诊为GIST的病例85例,回顾性分析性别、年龄、肿瘤部位、手术方式、首诊转移、淋巴结清扫及Flecther分级等因素对患者预后的影响.结果 本组患者的1年、3年、5年生存率分别为94%、60%、57%.单因素分析显示,GIST患者的预后与肿瘤原发部位、手术方式、Fletcher分级(肿瘤大小和核分裂数)以及有无首诊转移有关(P＜0.05),而与性别、年龄及是否行淋巴结清扫无关.多因素分析显示,有无首诊转移是影响预后的独立因素(P=0.020,β=4.226).结论 根治性手术仍然是目前原发GIST的首选治疗,首诊转移是影响预后的独立危险因素,故早期发现、早期诊断、早期手术治疗对GIST的预后显得尤为重要.同时,Fletcher分级也是评估GIST的有效而简便的方法之一.

Prognosis of patients with gastrointestinal stromal tumors

Objective To investigate the prognostic factors of gastrointestinal stromal tumors.Methods From Nov.1999 to Dec.2006,a total of 85 patients were diagnosed by postoperative pathology as gastrointestinal stromal tumors.The relationship between the prognosis of GIST and demographic factors、tumor location、operation style、preoperative metastasis、lymphadenectomy、grading of Fletcher were analyzed retrospectively.Results The 1 year、3 year and 5 year survival rate of these 85 patients were 94%,60%,57%respectively,Univariate analysis indicated that tumor location、operation style、grading of Fletcher and preoperative metastasis were significant predictors of survival(P<0.05),while demographics and lymphadenectomy were not statistically related with prognosis.Multivariate analysis showed that preoperative metastasis was the independent factor predicting the prognosis(P=0.020,β=4.226).Conclusion Radical surgical excision is still the therapy of choice for primary gastrointestinal stromal tumors.Preoperative metastasis is the independent factor predicting poor prognosis,therefore early diagnosis and treatment are very important for GIST.Fletcher grading is also a simple recalls to predict the prognosis of GIST.
