Figure 3 Treatment results and obstetrical outcomes in patients with gestational choriocarcinoma according to International Federation of Gynecology and Obstetrics (FIGO) score and FIGO stage. Response to treatment was assessed according to beta-human chorionic gonadotropin (beta-hCG) serum measurement. Complete response (CR) and progression were considered if beta-hCG dropped to a normal range and increased (or reached plateau), respectively. Patients with progression to first-line chemotherapy underwent salvage treatment: * etoposide, methotrexate, actinomycin D, cyclophosphamide and vincristine (EMACO) regimen to both patients and hysterectomy in one patient; ** EMACO regimen; *** cisplatin, vincristine, methotrexate, and bleomycin (POMB) regimen and hysterectomy were used in 1 patient, while another patient had rapid progression and died without salvage treatment.
