[Importance of CA-50 detection in malignant gynecologic tumors]

The role of Tumor Associated Antigens in the diagnosis of neoplasia is now actively investigated. The CA-50 antigen is known to be elevated in different types of gynecological neoplasia. In this study the CA-50 levels have been measured in 70 patients with ovarian, endometrial or cervical cancer. The data obtained show that the CA-50 levels, although elevated above normal in a high percentage of the patients studied, cannot be considered diagnostic for the presence of neoplasia.
