摘要 目的:探讨检测腺苷合成酶和Smad4的表达与大肠癌肝转移术后复发风险之间的相关性。方法选取121例确诊为大肠癌肝转移术后的患者,通过复习文献分析18个与大肠癌发病机制相关的基因,以此归纳预测大肠癌肝转移术后患者预后相关的临床病理变量。单因素和多因素Cox回归分析以确定与大肠癌肝转移术后复发相关的危险因素。结果转移瘤大小、肝受累体积、肝切除前的化疗、切缘阳性率、乙型肝炎、肝纤维化、转移瘤中胸苷酸合成酶和Smad4的表达8个因素与无进展生存期密切相关,原发瘤分期、术前CEA水平、转移瘤大小、肝脏受累体积、转移瘤数目、切缘阳性率、肝纤维化、胸苷酸合成酶和Smad4的表达9个因素与总生存期密切相关。调整了各个风险因素的影响后,仅有腺苷合成酶(HR=0.631,95%CI 0.422~0.944)和Smad4(HR=1.680,95%CI 1.047~2.695)两个因素的表达与大肠癌肝转移术后复发风险密切相关。结论肿瘤分子生物标志物检测腺苷合成酶和Smad4可以提高预测大肠癌肝转移术后患者复发风险的能力。
