评价 1 5 8例乳腺癌妇女和 1 63例健康对照者的血清硒和 dl-α-生育酚浓度。健康对照组血清硒浓度明显低于乳腺癌组。与文献比较 ,血清硒水平在安全范围内。另一方面 ,乳腺癌患者血清 dl- α-生育酚浓度明显降低。乳腺癌组和健康对照组血清 dl- α-生育酚的平均浓度均低于参考范围。低 dl- α-生育酚状态可以考虑是癌症发生的高危险因素。
Serum selenium and dl-α-tocopherol concentrations were evaluated in 158 women with breast cancer and 163 healthy controls. Serum selenium concentration in healthy control group was significantly lower than that in breast cancer group. Compared with the literature, serum selenium levels are within safe limits. On the other hand, serum concentrations of dl-α-tocopherol in breast cancer patients were significantly lower. The average concentrations of serum dl-α-tocopherol in breast cancer group and healthy control group were lower than the reference range. Low dl- alpha-tocopherol status can be considered a high risk factor for cancer.
