BJC:叶酸摄入与头颈部肿瘤风险

2017-12-01 MedSci MedSci原创

低水平叶酸会导致DNA复制、DNA甲基化和DNA修复障碍,但是饮食叶酸摄入与头颈部肿瘤风险之间的关系尚不清楚。BJC近期发表了一篇文章研究这一问题。

低水平叶酸会导致DNA复制、DNA甲基化和DNA修复障碍,但是饮食叶酸摄入与头颈部肿瘤风险之间的关系尚不清楚。BJC近期发表了一篇文章研究这一问题。

作者使用前瞻性前列腺、肺、结直肠和卵巢癌(PLCO)检测试验的的数据,评估叶酸摄入与头颈部肿瘤之间的关系。该研究共纳入101700例患者,186例患者确诊患有头颈部肿瘤。平均随访时间12.5年。使用纳入了年龄、性别、BMI、教育水平、种族、吸烟、饮酒及总水果蔬菜摄入等因素的Cox模型评估风险比和95%置信区间。研究结果表明,食物叶酸或食物中的人工叶酸摄入水平增加与头颈部肿瘤风险降低有关。食物叶酸摄入水平最高的风险比为0.35,人工合成叶酸摄入水平最低的风险比为0.49。总叶酸摄入,自然叶酸和补充性叶酸与头颈部肿瘤风险及其部位无关。作者并未发现吸烟、饮酒等与头颈部肿瘤风险之间的关系。

文章最后认为,该研究结果表明饮食叶酸摄入是头颈部肿瘤发病风险的保护性因素。
