Primary ovarian tumors in postmenopausal women: A 10-year review.

This retrospective study reports on 403 postmenopausal women with ovarian tumors treated at Siriraj Hospital over a ten-year period from 1988-1997. Of the total, 206 (51.1%) were benign, and 197 (48.9%) were malignant. Common epithelium was the most common type (77.9%) and germ cell was the second most common tumor (13.9%), found in this age group. The risk of malignancy increased with age of the patient (p<0.001). More than half of the cases had advanced disease (stage III or IV). Nulliparity, absominal distension as the presenting symptom and bilaterality were more commonly found in patients with malignant disease than those with benign tumors. However, tumor size between the tow group was not significantly different.
