[Use of a mixture of three types of antibodies for immuno-histologic detection of stomach cancer micrometastases].

The stomach carcinoma micrometastases to lymph nodes were revealed by nondirect immunoperoxidase method. The reaction was performed on the slides of lymph nodes stained with hematoxylin and eosin taken from pathomorphologic archives, by the mixture of polyclonal antibodies to carcinoembryonic antigen, beta-I-meconial antigen and pepsinogen C. The micrometastases were found in 7 of 58 cases (10.8%) that had initial histologic diagnosis "lack of metastases".
