以前的流行病学研究已经检查了肾细胞癌(RCC)风险与摄入植物性食物和抗氧化营养素之间的关系,但得出了不一致的结果。因此,我们在α -生育酚、β -胡萝卜素癌症预防(ATBC)研究队列中研究了水果、蔬菜、类胡萝卜素、类黄酮、维生素E和维生素C的摄入量与RCC风险之间的关系。在基线时,27,062名年龄在50-69岁之间的芬兰男性吸烟者完成了一份276项的饮食问卷,其中包括消费频率和份量的问题。在长达19年的随访中,255名男性患上了肾细胞癌。采用Cox比例风险模型估计相对风险(RR)和95%置信区间(CI)。尽管摄入量范围很大,但没有观察到水果、蔬菜或抗氧化营养素与肾癌风险之间的联系。例如,水果、蔬菜、总类胡萝卜素、总黄酮、总维生素E和维生素C的最高和最低四分位数的多变量相对危险度和95% ci分别为0.79(0.55-1.14)、1.23(0.85-1.79)、1.09(0.74-1.60)、0.83(0.57-1.21)、1.09(0.73-1.64)和0.99(0.67-1.46)(趋势值均为0.05)。我们的研究结果表明,饮食在男性吸烟者的RCC病因学中可能没有很大的作用,尽管有必要进一步研究非吸烟者、女性和不同种族人群的这些关联。
Previous epidemiologic studies that have examined the relationship between renal cell carcinoma (RCC) risk and intakes of plant foods and antioxidant nutrients have yielded inconsistent results. We therefore examined the associations between intakes of fruit, vegetables, carotenoids, flavonoids, vitamin E, and vitamin C and RCC risk in the Alpha-Tocopherol, Beta-Carotene Cancer Prevention (ATBC) Study cohort. At baseline, 27,062 male Finnish smokers aged 50–69 years completed a 276-item dietary questionnaire that included questions on frequency of consumption and portion size. During up to 19 years of follow-up, 255 men developed RCC. Cox proportional hazards models were utilized to estimate relative risks (RR) and 95% confidence intervals (CI). Despite a large range in intake, no association was observed between fruit, vegetables, or antioxidant nutrients and RCC risk. For example, multivariate RRs and 95% CIs for the highest versus the lowest quartile of intake were 0.79 (0.55–1.14), 1.23 (0.85–1.79), 1.09 (0.74–1.60), 0.83 (0.57–1.21), 1.09 (0.73–1.64), and 0.99 (0.67–1.46) for fruit, vegetables, total carotenoids, total flavonoids, total vitamin E, and vitamin C, respectively (all p-values for trend > 0.05). Our results indicate that diet may not play a large role in the etiology of RCC in male smokers, although further examination of these associations in nonsmokers, women, and diverse racial populations is warranted.
