| CA 15-3 |  |
Anti-CA15-3 antibody has been used for evaluating the primary site of a metastatic carcinoma of unknown origin and distinguishing between benign and malignant lesions. CA15-3 has been detected with immunohistochemistry in a wide spectrum of carcinomas, e.g. breast carcinomas (ductal and lobular), sarcomas (synovial sarcoma and malignant fibrous histiocytomas), and lung carcinomas. This marker can be used as a supplementary marker for epithelial differentiation. Anti-CA15-3 does not stain melanomas, or Ewing's sarcomas. Approximately 30% of hepatocellular carcinomas are positive for CA15-3.
