摘要 目的探讨术前红细胞分布宽度(RDW)对乳腺癌患者总体生存期的预测价值。方法回顾性分析280例浸润性乳腺癌患者的临床资料,收集患者术前RDW值。依据患者总体生存情况将患者分成生存组和非生存组,比较两组患者临床病理资料。通过受试者工作特征曲线确定RDW患者无病生存期和总体生存期的截点值,并根据截点值将入组患者分为低RDW组(RDW≤13.45%,188例)和高RDW组(RDW>13.45%,92例),比较两组患者5年生存率和临床病理因素。单因素分析评价各因素对预后生存的影响,并进行多因素Cox回归,筛选影响预后的独立因素,并进行生存分析。结果生存组与年龄、RDW、肿瘤大小、孕激素受体、淋巴转移及肿瘤临床分期有相关性(P<0.05)。治疗前RDW≤13.45%与RDW>13.45%的患者比较,高RDW组与肿瘤大小(P=0.000),阳性淋巴结转移(P=0.016)及肿瘤临床分期(TNM)晚期程度(P=0.001)有明显的相关性。高RDW组患者的无病生存率(P<0.001)及总体生存率(P<0.001)比低RDW组患者明显下降。Cox多元回归分析显示术前高RDW是不良无病生存期和总体生存期的独立危险因子,风险率分别为1.614(95%CI1.421~1.834,P<0.001)和1.507(95%CI1.309~1.735,P<0.001)。结论术前高RDW是影响乳腺癌患者预后的独立因素,乳腺癌患者术前RDW与无病生存期和总生存率有一定的相关性。
