20 young adults with cystic fibrosis (CF), including 2 with cancer, were found to have low serum selenium concentrations. Serum vitamin E concentrations were also low. It is suggested that low levels of circulating selenium are associated with increased risk of carcinoma, particularly in the presence of reduced vitamin E levels. Older patients with CF may be at increased risk for the development of carcinoma.
20名患有囊性纤维化（CF）的年轻成年人，其中包括2名患有癌症的患者，被发现血清硒浓度较低。血清维生素E浓度也较低。有人认为，循环硒水平低与患癌风险增加有关，特别是在维生素E水平降低的情况下。年龄较大的CF患者患癌风险可能会增加。
