肛门腺癌的治疗可能具有挑战性,这项研究旨在比较和分析肛门鳞状细胞癌和肛门腺癌患者的护理模式和生存结果的差异。

背景及目的:
肛门腺癌的治疗可能具有挑战性,这项研究旨在比较和分析肛门鳞状细胞癌和肛门腺癌患者的护理模式和生存结果的差异。

方法:
这是一项回顾性研究。研究人员在2004年至2014年间共选择了19539例患有II至III期肛门鳞状细胞癌或腺癌的患者纳入本项研究。所有患者按照治疗组分为单独手术,新辅助放化疗,手术,手术后辅助放疗或确定性放疗组。主要观察指标:比较两组患者和临床相关因素。Kaplan-Meier和Cox比例风险回归模型用于评估总体生存率。

结果:
在研究的患者中,有18346(93.9%)名患有原发性鳞状细胞癌,而有1193(6.1%)名患有原发性肛门腺癌。II期鳞状细胞癌的5年总生存率为69.2%,而II期腺癌的5年总生存为54.2%(p <0.001)。III期鳞状细胞癌的5年总生存率为55.2%,而III期腺癌的5年总生存为32.9%(p <0.001)。在多变量Cox回归分析中,单独使用化学放射治疗(HR,0.67;p = 0.008)与鳞状细胞癌的生存期改善有关。对于腺癌组,III期疾病(HR,2.26; p <0.001)和高肿瘤分级(HR,1.59; p <0.011)对生存率有负面影响,但根据接受的治疗类型,生存率没有差异。

结论:
与肛门鳞状细胞癌相比,肛门腺癌的5年总生存期较低。肛门腺癌的治疗似乎与直肠癌的治疗方法相似,并经常使用新辅助化学放疗。
