Objective: To evaluate the 8-day methotrexate (MTX)/folinic acid (FA) as a first-line chemotherapy regimen treatment in terms of complete regression of disease in women with low-risk gestational trophoblastic neoplasia (GTN). Material and Methods: All patients with low-risk GTN treated with an 8-day MTX/FA regimen were retrospectively included in the study. International Federation of Obstetrics and Gynecology and the modified World Health Organization Prognostic Scoring System were used to classify the risk of GTN. All women received diagnostic imaging evaluation before starting the treatment. The same MTX/FA regime was used repeating as a two-week cycle until normalization of the beta-human chorionic gonadotropin (ß-HCG), thus monthly ß-HCG follow-up was scheduled for up to 1 year. Results: Successful treatment was achieved in 56/66 (84.8%) patients. Nine (13.6%) women had resistance and 1 (1.6%) toxicity. The resistance patients were successfully treated with EMA-CO (etoposide, methotrexate, actinomycin D, cyclophosphamide, vincristine) protocol, whereas the patient who showed toxicity to the MTX/FA regime was successfully treated with actinomycin-D. Conclusion: Eight-day MTX/FA regime could be useful in low-risk GTN patients with good security margins. The toxicity rates in this protocol were determined as quite low. All resistance was treated successfully with the EMA-CO protocol.
