摘要: 目的 检测大肠癌患者根治术中植入氟尿嘧啶植入剂后外周血survivin、 caspase-3、 CD44V6的变化,探讨其对肿瘤微转移及预后的影响。方法 64例大肠癌患者 (Dukes B期、 C期) 随机分为治疗组和对照组, 每组32例。2组均行标准根治术, 治疗组术中植入氟尿嘧啶植入剂; 对照组术中未应用此药。采用RT-PCR方法测定手术前后外周血中survivin、 caspase-3表达水平, 流式细胞术检测CD44V6含量。结果 术前2组survivin、 caspase-3、CD44V6的水平差异无统计学意义 (P>0.05); 术后14 d, 治疗组survivin水平 (0.362±0.183) 低于对照组 (0.585±0.207), caspase-3水平(2.001±0.146) 高于对照组 (1.654±0.111); 术后CD44V6水平治疗组 (1.857±0.535) 和对照组(3.471±0.496)明显低于术前的 (9.557±1.170) 和 (9.729±0.943), 且治疗组CD44V6水平低于对照组 (均P<0.05)。结论 术中植入氟尿嘧啶植入剂, 对大肠癌的微转移及预后有重要意义, 有望提高大肠癌术后的远期疗效。

Abstract: Abstract Objectives:To observe the pre-and post-operational changes of the expressions of survivin/caspsae-3、CD44V6 in patients with colorectal cancer after intra-abdominal implantation fluorouracil sustained release implant. Methods:The peripheral blood levels of survivin/caspsae-3 were detected by RT-PCR and CD44V6 by FCM in 64 patients (fluorouracil sustained release implant were implanted intra-abdominally in 32 patients undergoing radical colorectal cancer surgery in the experimental group,while 32 cases undering radical surgery only served as controls) diagnosed with colon cancer.Results:No significant difierences of survivin/caspsae-3、CD44V6 were detected between the two groups before operation(P>0.05).survivin、CD44V6 levels were lower (P<0.05)while caspase-3 were higher(P<0.05) in the patients of the experimental group than the controls after operration.Conclusion:Fluorouracil sustained release implant could inhibit the expression of suvivin and raising caspase-3 to induce apoptosis,while reduce the expression of CD44V6 to effect the colorectal cancer micro transfer.
