Overview
Chemotherapy
Low-Risk Gestational Trophoblastic Neoplasia (FIGO Score 0–6)
Treatment commonly used treatment regimens include the following:
- The 8-day charing cross regimen. Methotrexate (50 mg IM on days 1, 3, 5, and 7) and folinic acid (7.5 mg PO on days 2, 4, 6, and 8). This may be the most common regimen worldwide
- Biweekly pulsed dactinomycin (1.25 mg/m2 IV)
- Weekly methotrexate (30 mg/m2 IM). Efficacy of this regimen appears to be low for choriocarcinoma and for patients with (FIGO) risk scores of 5 to 6
Other regimens in less-common use include the following:
- An 8-day regimen of methotrexate(1 mg/kg IM days 1, 3, 5, and 7) and folinic acid (0.1 mg/kg IM days 2, 4, 6, and 8)
- Methotrexate 20 mg/m2 IM days 1 to 5, repeated every 14 days
- Dactinomycin 12 μg/kg/day IV days 1 to 5, repeated every 2 to 3 weeks
- Methotrexate 20 mg IM daily, days 1 to 5; and dactinomycin 500 μg IV daily, days 1 to 5, repeated every 14 days
- Dactinomycin 10 μg/kg/day, days 1 to 5, repeated every 2 weeks
- Methotrexate 0.4 mg/kg/day IM daily on days 1 to 5, repeated after 7 days
- Etoposide 100 mg/m2/day IV on days 1 to 5, or 250 mg/m2 IV on days 1 and 3, at 10-day intervals
