title: Ovarian surface epithelium, ovulation and carcinogenesis.
abstract: It appears that ovarian surface epithelial cells activated by contact with gonadotropin-stimulated preovulatory follicles can release bioactive substances that weaken the tunica albuginea and apical follicular wall (e.g. collagenolytic enzymes) and induce cell death (e.g. apoptotic agents). However, a definitive obligatory role of the ovarian surface epithelium in ovulation remains equivocal. Epithelium exfoliated from the dome of ovulatory follicles is replenished by generative stem cell replication and migration from the wound edges. Mutagenesis has been related to successive bouts of ovulation and mitosis. Common epithelial ovarian cancer is a deadly insidious disease, mainly because it is asymptomatic until the malignancy has reached beyond the ovaries. The most important susceptibility factors are nulliparity and association to an affected first-degree relative. It will be critical to resolve whether parity and oral contraceptive use confer significant protection to women with a family history of ovarian carcinoma. Clearly, innovative approaches to non-invasive screening and treatment are needed. Early detection is the key to saving lives (90% cure by salpingo-ovariectomy alone if diagnosis is at Stage I). Active immunization with defined tumor epitopes or (passive) intraperitoneal administration of effector-functional humanized antibodies may be of special value in the regional management of common epithelial ovarian cancer.
