据llamands和Yu报道，由于在乳腺、肺、卵巢、子宫内股等不同部位的肿瘤中均发现了前列腺特异抗原（PSA），因此PSA对于前列腺细胞已不再具有特异性。PSA也存在于无乳汁妇女的乳头抽吸物中，且患乳腺癌时含量增多，这些发现为前列腺特异膜抗原（PSMA）的临床检测提供了可能。作 According to llanands and Yu, PSA is no longer specific for prostate cells because prostate specific antigen (PSA) is found in tumors in different parts of the breast, lung, ovary, and uterus. PSA is also found in nipple aspirate in lactation-free women and increases in breast cancer. These findings provide the possibility of clinical detection of prostate specific membrane antigen (PSMA).
