宣威地区肺癌患者血清和肺组织硒水平研究
Serum and Lung Tissue Selenium Measurements in Subjects with Lung Cancer from Xuanwei, China
摘要
Abstract
Background and objective Xuanwei is an area of the highest incidence and mortality with lung cancer in China. The aim of this study is to determine serum selenium concentrations in lung cancer patients from Xuanwei as well as selenium levels of cancerous tissues, cancer-adjacent pulmonary tissues, and normal pulmonary lung tissues from lung cancer patients, and the relationship between selenium and the high incidence of lung cancer in Xuanwei. Methods One hundred and twenty female adults from Xuanwei were enrolled in the study (60 lung cancer patients and 60 with non-tumor and non-respiratory diseases, respectively) and blood samples were collected. Sixty fresh cancerous tissues and their adjacent as well as normai tissues were collected (31 samples from lung cancer patients living in Xuanwei for more than 2 years and 29 from patients in other regions of Yunnan Province outside of Xuanwei, respectively). Serum and tissue selenium concentrations were assayed using a fluorometric method. Results Women with lung cancer had a mean serum selenium value (55.22 μg/L±13.34 μg/L)of averagely 8.47％, significantly lower than that in subjects with non-tumor and non-respiratory disease controls (60.33 μg/L±13.82 μg/L)(P＜0.05). Selenium concentrations in the tumor tissues (0.105 μg/g±0.034 μg/g) were statistically lower than that of normal ones (0.140 μg/g±0.048 μg/g)(P＜0.05) from lung cancer patients in Xuanwei. Statistical differences had not been found between the cases from Xuanwei and non-Xuanwei district, adenocarcinoma and squamous cell carcinoma, among Stage Ⅰ, Stage Ⅱ, stage Ⅲ groups. Conclusion Lower serum selenium state was negatively related to the incidence of lung cancer in Xuanwei. It was likely that lower selenium level of lung tissues was potential risk factor to lead to lung cancer.关键词
