摘要 目的探讨微卫星不稳定性对结肠癌术后FOLFOX方案辅助治疗的预后价值。方法 135例结肠癌术后行FOLFOX方案辅助治疗的患者作为研究对象,免疫组化方法检测肿瘤组织中修复DNA复制错误的错配修复蛋白表达,包括MLH1、MSH2、MSH6及PMS2蛋白的表达,分析微卫星不稳定性与患者临床特征及预后的相关性。结果微卫星不稳定性与患者肿瘤直径(χ~2=9.727,P<0.05)、淋巴转移(χ~2=13.172,P<0.05)、TNM分期(χ~2=11.867,P<0.05)及肿瘤部位(χ~2=5.224,P<0.05)有关,与年龄(χ~2=0.010,P>0.05)和性别(χ~2=0.953,P>0.05)无关。微卫星不稳定性患者的总生存期为(31.96±9.39)个月,优于微卫星稳定性患者的(21.27±11.45)个月,差异具有统计学意义(t=5.896,P<0.05)。微卫星不稳定性患者的无疾病生存期为(23.61±8.63)个月,微卫星稳定性患者的(14.51±10.41)个月,差异具有统计学意义(t=5.489,P<0.05)。多重变量分析表明,微卫星不稳定性是患者总生存期[HR=2.383,95%CI=(1.262,4.503),P=0.003<0.05]和无疾病生存期[HR=2.356,95%CI=(1.370,4.049),P=0.003<0.05]的独立预后因素。结论微卫星不稳定性是结肠癌术后FOLFOX方案辅助治疗患者的独立预后因素。
