简介:摘要目的将TC化疗方案与放疗联合用于高危子宫内膜癌术后患者治疗中,对其疗效进行评价。方法对我院收治的61例高危子宫内膜癌术后患者分组研究,所有患者均行筋膜下子宫及双附件切除术+淋巴结切除术治疗,乙组术后行放射治疗,甲组在此基础上联合TC化疗方案,对两组治疗结果进行评价。结果甲组腹膜后淋巴结、肺远处转移率分别3.23、0,盆腔、阴道局部复发率分别为0、3.23%,与乙组13.33%、10.0%、6.67%、16.67%相比,相对更低(p<0.05);甲组骨髓抑制出现率与乙组相比,相对更高(p<0.05),两组腹泻、脱发、神经毒性等不良反应出现率相比,差异不明显(p>0.05);甲组3年生存率为90.32%,与乙组66.67%相比,相对更高(p<0.05)。结论TC化疗方案与放疗联合用于高危子宫内膜癌术后患者治疗中效果理想,可降低远处转移率、局部复发率,提升3年生存率,但与单纯放疗相比,其出现骨髓抑制不良反应较高,临床应引起重视,给予释放措施防治,以提升患者生存质量。
