Ovarian cancer is the leading cause of death from gynecologic malignancy and the fifth cause of cancer death in women in the United States. The most common and lethal histologic subtype of epithelial ovarian cancer is high-grade serous carcinoma (HGSC), which generally presents at an advanced stage. HGSC may be associated with BRCA1 and BRCA2 mutations. Historically, HGSC was believed to originate from the ovarian epithelial cells. However, more recent evidence supports the idea that most ovarian cancers originate in the fallopian tube epithelium in both high-risk women and in the general population. Serous tubal intraepithelial carcinomas may ultimately evolve into ovarian or peritoneal cancer. As a result, prophylactic salpingectomy with conservation of the ovaries has become an increasingly more common practice for premenopausal women undergoing risk-reducing surgery. Because the fallopian tube is now recognized as the most common potential site of origin of ovarian carcinoma, there is ongoing research to explore molecular and genetic factors that may be critical in the development of this disease. Further research is needed to identify novel opportunities for early detection and screening of ovarian cancer with the ultimate goal of increasing overall survival.
