24例直肠间质瘤的临床特点与外科治疗分析

[目的]探讨直肠间质瘤的临床特点及外科治疗。[方法]回顾性分析1986～2007年间收治的24例直肠间质瘤患者的临床资料。[结果]24例患者中男性14例，女性10例。中位年龄50岁。手术切除23例，其中局部切除16例，根治性切除7例，9例术后复发（39．1％），两种术式的术后复发率差异无显著性（X^2=1．371，P〉0．05）。5年生存率为92．0％，3年、5年无病生存率分别为72．0％和57．6％，中位无病生存时间为61个月。[结论]对于最大径〈5cm的低位直肠间质瘤，局部切除是一种安全可行的手术方式。

Clinical Features and Surgical Treatment in 24 Cases with Rectal Stromal Tumor

[Purpose ] To investigate the clinical features and surgical treatment for rectal stromal tumor. [Methods] The clinical data of 24 cases admitted in our hospital from1986 to 2007 were analyzed retrospectively. [Results] There were 14 male patients and 10 female patients in the 24 cases. The median age was 50 years old. Among all the 23 patients received resection, 16 underwent local resection and 7 underwent radical resection. Nine patients were recurrent （39.1%）. There were no significant difference on the recurrent rate between those two kinds of resection （X^2=1.371 ,P〉0.05）. The five-year survival rate was 92.0%. The three-year and five-year disease-free survival rate was 72.0% and 57.6%, respectively. The median duration of disease-free survival was 61 months. [ Conclusion ] Local resection is safe and proper for gastrointestinal stromal tumor smaller than 5cm in the lower portion of rectum.
