Gestational Trophoblastic Tumors and Neoplasia Treatment (PDQ®): Treatment - Health Professional Information [NCI] - Recurrent or Chemoresistant Gestational Trophoblastic Tumor Treatment
Recurrent disease indicates failure of prior chemotherapy unless initial therapy was surgery alone. One study found recurrence of disease in 2.5% of patients with nonmetastatic disease, 3.7% of patients with good-prognosis metastatic disease, and 13% of patients with poor-prognosis metastatic disease. Nearly all recurrences occur within 3 years of remission (85% before 18 months). A patient whose disease progresses after primary surgical therapy is generally treated with single-agent chemotherapy unless one of the poor-prognosis factors that requires combination chemotherapy supervenes. Relapse after prior chemotherapy failure automatically places the patient into the high-risk category. These patients should be treated with aggressive chemotherapy.
Reports of combination chemotherapy come from small retrospective case series. Long-term disease-free survival, in excess of 50%, is achievable with combination drug regimens.[Level of evidence: 3iiiDii] A variety of regimens have been reported that include combinations of the following:[3,4,5,6,7]

A select group of patients with chemotherapy-resistant and clinically detectable gestational trophoblastic tumors may benefit from salvage surgery.[Level of evidence: 3iiiDii]
Current Clinical Trials
Check for U.S. clinical trials from NCI's list of cancer clinical trials that are now accepting patients with recurrent gestational trophoblastic tumor. The list of clinical trials can be further narrowed by location, drug, intervention, and other criteria.
