Serum levels of tumor-associated trypsin inhibitor (TATI) in benign and malignant gynecological diseases.

ABSTRACT

The behavior of tumor-associated trypsin inhibitor (TATI) as a marker for gynecological cancer was studied in a control population and in patients with different benign and malignant diseases. When a cut-off level of 21.4 micrograms/l was used the specificity was 100% in patients with benign diseases. The sensitivity in patients with malignant tumors was low for cervical and corpus cancer, 13% and 14%, respectively, whereas it was 33% in all the ovarian malignant tumors, reaching 60% in the mucinous type. There was a clear correlation between TATI level and stage.
