摘要 目的对T4期直肠癌采用调强放疗结合同步化疗进行术前治疗,观察临床疗效及安全性。方法按照入选标准选择T4期直肠癌患者30例,进行术前调强放疗和单药卡培他滨化疗,并完成直肠癌手术,对临床肿瘤降期、肿瘤标志物癌胚抗原(CEA)、不良反应及随访数据等相关资料进行分析。结果 30例患者放化疗后出现病理缓解22例,降期率73.3%,其中7例出现完全病理缓解,完全缓解率23.3%;8例出现肿瘤未降期或进展。放化疗不良反应以轻度直肠炎、粒细胞减少为主,发生率10.0%。分析放化疗降期相关因素,放化疗前CEA越高,放疗后yp T分期越晚(P<0.01)。放疗前CEA水平与近期复发转移相关,完全缓解者近期复发转移率也明显低于肿瘤进展或未降期者(P<0.05)。结论 T4期直肠癌采用改良的术前放化疗,可取得较好的临床效果,可进一步推广应用;CEA对直肠癌术前放化疗敏感性有一定的预测价值。
