Gestational Trophoblastic Tumors and Neoplasia Treatment (PDQ®): Treatment - Health Professional Information [NCI] - Epithelioid Trophoblastic Tumor Treatment
These tumors are exceedingly rare. There is little information to guide therapy. However, they 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 these tumors are malignant in behavior, but they are not very responsive to systemic therapy. A variety of chemotherapy regimens have been used.
Purpose of This Summary
This PDQ cancer information summary for health professionals provides comprehensive, peer-reviewed, evidence-based information about liver (hepatocellular) cancer screening. It is intended as a resource to inform and assist clinicians who care for cancer patients. It does not provide formal guidelines or recommendations for making health care decisions.
Reviewers and Updates
This summary is reviewed regularly and updated as necessary by the PDQ Screening and...
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.
