Abstract
Ovarian cancer is the most lethal gynecological malignancy as it is diagnosed at a late clinical stage in more than 80% of patients. The development of diagnostic tests that can detect all types of ovarian cancers with high specificity and sensitivity, and at an early stage would improve survival rates. Serum inhibin is an ovarian hormone involved in the regulation of fertility, decreasing to undetectable levels after menopause. Certain ovarian malignancies, such as mucinous carcinomas and granulosa cell tumors, continue to produce inhibin, which is detectable in serum. A test for serum inhibin has been developed which is able to diagnose granulosa cell tumors and mucinous carcinomas with high accuracy. When the inhibin assay is used in conjunction with the CA125 test, which detects epithelial ovarian carcinomas, the two tests detect the majority of ovarian cancers with high sensitivity (95%) and specificity (95%). This article discusses the application of the inhibin test in ovarian cancer.
