JAMA Dermatol:维生素A摄入量与皮肤鳞状细胞癌风险的关系

2019-08-03 海北 MedSci原创

类视黄醇是维生素A的生物活性形式,其对维持上皮成熟和分化至关重要。合成类视黄醇被用于具有潜在不利影响的高风险人群中的皮肤癌的化学预防。

现今为止,关于维生素A摄入和皮肤鳞状细胞癌(SCC)风险的流行病学数据是有限的。

最近进行的一项研究的目的就是探讨维生素A摄入量是否与SCC风险降低有关。

该队列研究在护士健康研究(1984-2012)和卫生专业人员随访研究(1986-2012)中前瞻性地检查了维生素A和类胡萝卜素的摄入量以及SCC风险。研究人员反复评估了饮食。

事件SCC由病理报告证实。数据分析于2017年6月21日至2018年12月4日进行。

Cox比例风险回归模型用于计算队列特异性风险比(HRs)和95%CI。计算群组特异性结果的合并HR。

护士健康研究的(平均[SD]年龄50.4 [7.2]年)75170名女性和卫生专业人员随访研究的48400名男性(平均[SD]年龄,54.3) [9.9]年)中共有3978例SCC病例记录在案。

维生素A总量较高与SCC风险降低有关。视黄醇和一些类胡萝卜素摄入量增加也与SCC风险降低有关。与最低五分位数相比,最高五分位数的合并HR为0.88(总视黄醇;95%CI,0.79-0.97;趋势P = .001),0.86(β-隐黄质;95%CI,0.76-0.96; P = .001),0.87(番茄红素;95%CI,0.78-0.96; 趋势P <.001),0.89(叶黄素和玉米黄质;95%CI,0.81-0.99;趋势P = 0.02)。

结果通常与性别和其他SCC风险因素一致。

因此,该研究表明,维生素A的摄入量增加与SCC发病风险降低有关。需要进一步的研究来确定维生素A补充剂是否在化学预防SCC中起作用。
