Objective: To remark characteristics of clinical, subclinical, and results of chemotherapy on gestational trophoblastic neoplasia patients. Methods: A retrospective combined prospective study was conducted on 36 women with low and high risks of gestational trophoblastic neoplasia from January 2015 to October 2020. The low - risk group was treated with methotrexate alone. The high - risk group was treated with EMA/CO (etoposide, methotrexate, actinomycin D/ leucovorin calcium, vincristine, cyclophosphamide). Results: The most common age was >
40 years old. Patients admitted to the hospital because of vaginal bleeding accounted for the highest rate of 52.8%. Most of the patients (83.3%) had initial Beta - HCG <
100000. The most common histopathological form is choriocarcinoma, with 50%. Lung metastatic lesions accounted for the highest (53.8%). The proportion of low - risk and high - risk patients was about 50%. The complete response rate was 83,3% with the methotrexate regimen and was 83,3% with EMA/CO regimen. The proportion of patients with grade 3.4 toxicity accounted for a small proportion, mainly in hematology. Conclusion: The regimens had good results, high response rates, and safety.
