A series of 18 patients with proliferating or borderline ovarian tumours and 18 with invasive ovarian tumours is discussed. Proliferating tumours occurred at a younger mean age than invasive disease, and presented at an earlier stage, both contributing factors to their more favourable outlook. Histopathological assessment revealed that the majority of both proliferating and invasive tumours were of serous origin. Mucinous cell type occurred less often as did the endometrioid and clear cell types. The management of the proliferating tumours involved 'radical' surgical procedures in 11 of 18 (61.6%) patients. Only 7 patients (38.8%) had conservative surgical procedures performed. Six patients (33%) had adjuvant chemotherapy while 2 (11%) also underwent abdominopelvic irradiation. All patients with invasive disease had radical surgery and adjuvant chemotherapy and 2 also received abdominopelvic irradiation. The fact that epithelial malignancies of the ovary do occur in younger women needs to be remembered by gynaecologists contemplating surgical procedures on younger patients with adnexal masses. Proliferating or borderline tumours tend to occur more frequently in the younger age groups, and contrary to the implication of their name, they are associated with significant morbidity and mortality.
