CA-125 is elevated in which proportion of epithelial ovarian cancer?

Explanation:
CA-125 is a tumor marker often elevated in epithelial ovarian cancer. It is elevated in about 80% of cases overall, with higher sensitivity in advanced disease and lower sensitivity in early-stage tumors. This makes CA-125 useful for monitoring response to therapy and detecting recurrence, though it isn’t perfect and can be raised in benign conditions as well. So the proportion is roughly four-fifths, or 80%.
