DCR: 肛门上皮内瘤变III期的患者患肛门癌的风险因素

2018-11-16 MedSci MedSci原创

诊断为肛门上皮内瘤变III期的患者之后发生肛门癌的风险因素目前还不明确,因此本研究的目的是评估肛门上皮内瘤变III患者肛门癌发生的风险因素。

背景
诊断为肛门上皮内瘤变III期的患者之后发生肛门癌的风险因素目前还不明确,因此本研究的目的是评估肛门上皮内瘤变III患者肛门癌发生的风险因素。

方法
这是一项回顾性研究,患者为被诊断患有肛门上皮内瘤变III的患者。主要观察指标是肛门鳞状细胞癌发生率。使用逻辑回归和Cox比例风险模型鉴定肛门癌的预测因子。

结果
共有2074例肛门上皮内瘤变III患者被确诊并接受随访,中位时间为4年(四分位数间距为1.8-6.7 年)。在该队列中,171名患者(8.2%)随后发展为肛门癌。从肛门上皮内瘤变III诊断到肛门癌诊断的中位时间为2.7年(四分位距,1.1-4.5 年)。发生肛门癌的52名患者(30.4%)分期为T2或是更高的类型。初次肛门上皮内瘤变III的消融治疗与肛门癌风险降低相关(OR = 0.3(95%CI,0.1-0.7);p= 0.004)。肛门上皮内瘤变III后肛门癌的5年发病率为每年9.5%。

结论
本项研究的结果表明肛门上皮内瘤变III的患者中约有10%的患者预计在5年内患上肛门癌。消融手术与降低癌症风险有关。
