恶性胃间质瘤的诊断与外科治疗

The Diagnosis and Surgical Treatment of Malignant Gastric Stromal Tumors

摘要: 目的探讨恶性胃间质瘤的诊断及治疗方法。方法对48例经手术治疗的恶性胃间质瘤的临床资料进行回顾性分析。结果本组中临床症状表现为上腹不适或疼痛29例,上消化道出血18例,腹部包块5例。行胃楔形切除术17例,近端胃大部切除术19例,远端胃大部切除术12例。肿瘤平均直径为7.2cm,胃周淋巴结转移2例(4.2%)。免疫组化结果CD117阳性46例(95.8%),CD34阳性39例(81.3%)。术后复发5例,远处转移6例,5年生存率为61.8%。结论恶性胃间质瘤的诊断主要依靠术后切片及免疫组化,治疗以手术为主,术后复发及转移的发生率较高,其预后主要与肿瘤大小相关。

Abstract: Objective To investigate the diagnosis and surgical treatment of malignant gastric stromal tumors. Methods The clinical data of 48 cases with malignant gastric stromal tumor were analyzed retrospectively.
