Abstract

Tumors of low malignant potential (also called borderline tumors) account for approximately 10% of malignant ovarian neoplasm. Borderline tumors have a much better prognosis and, because they are noninvasive, may be treated less radically than invasive ovarian cancer. The ability to distinguish borderline tumor from early stage malignant disease preoperatively considerably influences surgical treatment, and allows improved counseling of patients. CA 125 is a useful tumor marker in the diagnosis of malignant ovarian tumors. However, in the case of borderline ovarian tumor, the value of CA 125 as a diagnostic tool seems to be invalid. Herein, we report a case of borderline ovarian tumor with extremely elevated serum CA 125 level.

Key Words: Borderline tumors, CA 125, Tumor marker
