摘要
目的探讨小肠胃肠间质瘤（GIST）的治疗及预后影响因素。方法回顾性分析天津医科大学附属肿瘤医院2002年4月至2010年11月收治的经手术治疗且有完整随访资料的64例小肠GIST患者的临床和随访资料。结果全组患者术后均未接受化、放疗．有14例患者术后予以伊马替尼靶向治疗。64例小肠GIST患者5年生存率为51．2％；61例R0切除患者术后复发转移27例（44．3％）。单因素预后分析显示，手术方式（P=0．001）、肿瘤大小（P=0．018）、周围组织粘连侵犯（P=0．015）、伴发远处转移（p=0．000）、肿瘤坏死出血（p=0．032）、F1etcher分级（P=0．027）及就诊时症状（p=0．012）与小肠GIST患者预后有关。多因素预后分析显示，周围组织粘连侵犯（P=0．026）、伴发远处转移（P=0．000）和就诊时症状（P=0．019）是小肠GIST患者预后的独立影响因素。结论评估小肠GIST患者的预后，应结合手术方式、肿瘤大小、与周围组织脏器有无粘连侵犯、有无伴发远处转移、有无肿瘤坏死出血、就诊时症状、Fletcher分级以及靶向治疗情况进行多方面考虑。
Objective To investigate treatment and prognostic factors of gastrointestinal stromal tumor （GIST） in the small intestine. Methods The clinicopathological data of 64 patients with GIST in the small intestine admitted to the Tianjin Medical University Affiliated Cancer Hospital between April 2002 and November 2010 were analyzed retrospectively and the prognostic factors were evaluated. Results No patients in this cohort received chemotherapy or radiation therapy. Fourteen patients underwent post-operative imatinib targeted therapy. The overall 5-year survival rate was 51.2% and the post-operative recurrence rate of 61 cases undergoing R0 resection was 44.3%. Univariate analysis revealed that the complete tumor resection （P=0.001）, tumor size （P=0.018）, adhesion or invasion to surrounding tissue and organs （P=0.015）, concurrent distant metastasis （P=0.000）, tumor hemorrhage （P=0.032）, Fletcher classification （P=0.027） and symptom （P=0.012） were associated with prognosis. Multivariate analysis demonstrated that adhesion or invasion to surrounding tissue and organs（P=0.026）, concurrent distant metastasis （P=O.000） and symptom （P=0.019） were independent prognostic factors for survival. Conclusion The survival evaluation of patients with small intestinal GIST depends on surgery, tumor size, adhesion or invasion to surrounding tissue and organs, concurrent distant metastasis, tumor hemorrhage, symptom, Fletcher classification, and use of targeted therapy.
