High-Risk Gestational Trophoblastic Neoplasia (FIGO Score ?7) Treatment

continued...

Examples of other regimens that have been used include the following:[1]

  • MAC: Methotrexate, folinic acid, dactinomycin, and cyclophosphamide.
  • Another MAC: methotrexate, dactinomycin, and chlorambucil.
  • EMA: etoposide, methotrexate, folinic acid, and dactinomycin (EMA/CO without the CO).
  • CHAMOCA: methotrexate, dactinomycin, cyclophosphamide, doxorubicin, melphalan, hydroxyurea, and vincristine.
  • CHAMOMA: methotrexate, folinic acid, hydroxyurea, dactinomycin, vincristine, melphalan, and doxorubicin.

Brain metastases are associated with poor prognosis, particularly when liver metastases are also present.[6,7,8] However, even patients with brain metastases may achieve long-term remission in 50% to 80% of cases.[3,4,8] Patients with central nervous system (CNS) metastases receive additional therapy simultaneously with the initiation of systemic chemotherapy. Some centers utilize whole brain irradiation (30 Gy in 2 Gy fractions) with or without intrathecal methotrexate.[6] However, some investigators omit the cranial radiation, relying on replacement of the standard dose of methotrexate in the EMA/CO regimen with the higher dose of 1000 mg/m2 IV for 24 hours on the first day, as noted above, to achieve therapeutic CNS levels.[8]

Current Clinical Trials

Check for U.S. clinical trials from NCI's list of cancer clinical trials that are now accepting patients with high risk metastatic gestational 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.
