【摘要】 对２０３例肿瘤患者和４０例健康对照组血清硒研究表明，肿瘤患者血清硒显著低于健康组（Ｐ＜０．０１～０．００１），而不同肿瘤患者之间无差异，肺癌患者不同分期之间也无统计学意义，结果认为低硒水平可能是肿瘤患者的固有特性。更多还原

【Abstract】 The selenium (Se) concentration of 203 cancer patients (Lung cancer 66;Liver cancer 52;Stomach cancer 41;Breast cancer 24;Esophagus cancer 20;)and 40 healthy subjects were studied. Results showed that the cancer patients serum Se levels were significantly lower than that of healthy subjects (P<0.01～0.001). No statistical difference in Se levels of different cancer patients and between stages of Lung cancer patients.The results suggested that the lower serum Se concentration was inherent character of cancer patients.更多还原
