Reports have been made that the pregnancy zone protein (PZ) is found in increased amounts in sera of patients with malignant disease. The serum concentration of PZ was measured by a radioimmunoassay in 83 women with the diagnosis of gynaecological cancer or other malignancies. Values did not significantly differ from values previously recorded in apparently healthy women. There was no support for previous data of increased levels of PZ in cancer patients, when the age-dependent increase of this serum factor was considered.
已有报告称，在恶性疾病患者的血清中发现妊娠区蛋白（PZ）含量增加。通过放射免疫分析法对83名被诊断为妇科癌症或其他恶性肿瘤的女性的血清PZ浓度进行了测量。这些值与先前在明显健康的女性中记录的值没有显著差异。当考虑到这种血清因子随年龄的增加时，没有证据支持先前关于癌症患者中PZ水平升高的数据。
