David Gershenson on Challenges to Advancing Treatment for Rare Ovarian Cancers

David Gershenson, M.D., of MD Anderson Cancer Center, explains the difficulty of advancing treatment of rare ovarian cancers: malignant ovarian germ cell tumors, sex cord stromal tumors, and types of epithelial tumors such as ovarian clear cell carcinoma, ovarian low-grade serous carcinoma, and mucinous tumors. With such a low number of cases and not much interest from pharmaceutical companies, it is hard to conduct clinical trials in these areas.
