分析了58名患乳腺癌妇女血清中的DDT主要代谢产物DDE以及PCBs含量。血样采于1985和1991年,采样1～6个月后这58名妇女被诊断为癌症。对照组选自同一研究的171名未患癌症的妇女,是从按年龄和月经情况匹配的各组随机选取的。乳腺癌患者的平均DDE水平(35%)显著高于对照组。校正已知的生育和健康危险因素后,患乳腺癌的相对危险度与DDE水平呈明显正相关。
The DDT and PCBs contents in serum of 58 women with breast cancer were analyzed. The blood samples taken in 1985 and 1991, the sampling of 1 to 6 months after the 58 women were diagnosed with cancer. A control group of 171 women without cancer from the same study were randomly selected from groups matched by age and menstrual status. The average DDE level (35%) in breast cancer patients was significantly higher than that in controls. Correction of known fertility and health risk factors, the relative risk of breast cancer and DDE levels were positively correlated.
