Epithelioid Trophoblastic Tumor Treatment
Epithelioid trophoblastic tumors (ETTs) are exceedingly rare, and there is little information to guide therapy. However, these tumors are similar in behavior and prognosis to placental-site trophoblastic tumors, so it is reasonable to manage them similarly. (Refer to the Placental-Site Gestational Trophoblastic Tumor Treatment section of this summary for more information.) Only a minority of ETTs are malignant in behavior, but they are not very responsive to systemic therapy. A variety of chemotherapy regimens have been used.
Current Clinical Trials
Check for U.S. clinical trials from NCI's list of cancer clinical trials that are now accepting patients with epithelioid trophoblastic tumor. The list of clinical trials can be further narrowed by location, drug, intervention, and other criteria.
General information about clinical trials is also available from the NCI Web site.
