title: [The role of monoclonal antibodies to the epithelial membrane antigen in the diagnosis of human tumors].
abstract: The paper discusses the possibility of the use of the Soviet-made ICO 25 monoclonal antibodies to membrane antigen of lipid globules of the human milk for differential diagnosis of human tumors. ICO 25 monoclonal antibodies reliably detected the above antigens in normal epithelial and breast cancer cells. However, these antigens cannot be considered strictly specific for breast tissue. They were found in various human epithelial tissues, in the majority of epithelial tumors and lymph node metastases. Staining for ICO 25 monoclonal antibodies was negative in non-epithelial tumors. The above antibodies proved a useful marker for the identification of epithelial origin of primary tumors and their metastases showing unclear histology. They can be used to differentiate between epithelial and non-epithelial malignancies as well as to detect micrometastases and areas of microinvasion. Paraffin-embedded samples can be used for immunohistochemical examination.
