直肠癌Dixon术后局部复发相关因素分析

目的分析直肠癌Dixon术后局部复发相关因素。方法回顾性分析按全直肠系膜（TME）标准手术治疗的低位直肠癌患者100例的临床资料。结果100例患者术后骶前复发率10．0％，与大体类型、组织学分型及肠腔、腹腔脱落肿瘤细胞相关，且为影响患者预后的独立因素。无局部复发组90例，5年生存率为76．0％，半数生存期62个月；局部复发组10例，5年生存率为5．0％，半数生存期24个月。结论低位直肠癌术后局部复发相关影响因素有大体类型、组织学分型及肠腔、腹腔脱落肿瘤细胞，局部复发严重影响患者预后。

Analysis of the related factors of local recurrence in patients with rectal cancer after Dixon operation

Objective To analyze the related factors of local recurrence in patients with rectal cancer after Dixon operation. Methods A retrospective analysis of clinical data of 100 patients from September 2005 to September 2007 in our hospital by TME standard surgicai treatment of low rectal cancer was carried out. Results Of 100 patients, the pre-sacral recurrence rate was 10. 0%, with gender, age, tumor size, tunor invasion lumen circumference,depth of invasion,lymph node metastasis and Duke's stage has nothing to do with the gross type,histological type and lumen,peritoneal tumor cell shedding,and as an independent prognostic factor. Of 90 patients without local recurrence,the 5-year survival rate was 76. 0% ,haff of the survival of 62 months;10 cases of local recurrence,5-year survival rate was 5. 0%, half of the survival of 24 months, suggested that local recurrence in patients influenced the prognosis. Conclusion The low local recurrence of rectal cancer related factors were gross type,histological type and the intestine, peritoneal tumor cells shed, seriously affect the prognosis of patients with local recurrence.
