CGH:乳糜泻患者发生各种癌症风险的差异分析

2022-01-27 MedSci原创 MedSci原创

乳糜泻一般指麦胶性肠病。 麦胶性肠病又称乳糜泻、非热带性脂肪泻,在北美、北欧、澳大利亚发病率较高,国内很少见。

乳糜泻(CD)在欧洲人群中的患病率为 1%,不少研究已经探讨过乳糜泻患者的总死亡风险,但仅有少数研究系统地分析了乳糜泻患者与一般人群相比具体死亡原因的差别。研究人员最近对瑞典的特定病因死亡率进行了分析,发现CD患者因癌症而死亡的人数增加(HR 1.29;95%CI 1.22-1.36)。先前的多项研究发现,CD与各种恶性肿瘤的风险有关,但也有一些人发现癌症的死亡率没有增加。然而,这些研究主要是基于20世纪诊断的病人的数据,当时还没有广泛的CD血清学检测。因此,本项研究旨在对 CD患者中的癌症风险进行了一项更大样本的研究。

 

研究人员使用由瑞典组织病理学数据库的流行病学队列确定了瑞典所有患有 CD 的患者,CD患者的诊断定义为十二指肠/空肠绒毛萎缩。然后每名患者按年龄、性别和地区匹配了≤5 名对照者。最后使用分层 Cox 比例风险模型,对所有患者进行了从诊断到首次癌症发生时间的随访。

 

研究结果发现自2000年以来,共有30080名被诊断CD出来。中位随访 11.5 年后,CD 患者和对照组的癌症发病率分别为 6.5 和 5.7/1000 人年。癌症的总体风险增加(风险比 [HR],1.11;95% [CI],1.07-1.15),但仅在 CD 诊断后的第一年显着升高(HR,2.47;95% CI , 2.22–2.74) 而随后几年的癌症发生风险没有明显变化 (HR, 1.01; 95% CI, 0.97–1.05),尽管血液、淋巴增生、肝胆和胰腺癌的风险仍然存在。60岁后诊断为 CD 的总体风险最高(HR,1.22;95% CI,1.16-1.29),并且在 40 岁之前诊断的患者中没有增加。

本项研究发现即使在最近几年,CD 中患癌症的风险也在增加,但这种风险增加仅限于 40 岁以后被诊断为 CD 的人,并且主要出现在诊断的第一年内。
