title: CA-125 in gynecological malignancies.
abstract: CA-125 is an antigenic determinant that can be demonstrated in the majority of epithelial ovarian carcinomas. It can be measured in the serum with a radioimmunoassay by means of a monoclonal antibody. The tumor marker has a low specificity but high sensitivity for ovarian cancer, especially for serous cystadenocarcinoma. In our investigation we were interested in particular in the correlation between CA-125 and the histological findings at second-look operation. In 22 patients, second-look was performed after 6 cycles of chemotherapy, in 16 patients active tumor was demonstrated. In 6 patients with negative CA-125 values, residual tumor less than 1 cm was demonstrated. In order to verify a complete remission, a second-look operation has to be performed. No false-positive CA-125 levels were found. In all patients with elevated CA-125 serum values, residual tumor was histologically confirmed at second look.
