Abstract
Objectives: Clinical and subclinical characteristics of a group of patients with MTX-resistant low-risk gestational trophoblastic disease treated with a 5-day ActinomycinD (ACTD) monotherapy regimen.
Subjects and methods: 40 patients with MTX-resistant low-risk gestational trophoblastic disease treated with ACTD for 5 days at the National Hospital of Obstetrics and Gynecology from January 2019 to October 2021.
Methods: A retrospective descriptive cross-sectional study without a control based on the medical records of the National Hospital of Obstetrics and Gynecology.
Results: The overall success rate was 85%, especially in the group of patients with pretreatment βhCG concentration ≤ 300IU/l, the cure rate reached 91.2% with p=0.033. The difference is statistically significant with OR=10.33. 95% CI: 1.44-75.69. The FIGO score at the time of diagnosis also contributes to the prognosis of treatment response. From 0 to 2 points, there are no drug-resistant patients. The recovery ability of the group with the FIGO score from 0 to 2 points was 1.46 times greater than that of the group of patients with 3 or more points. The difference was statistically significant with p=0.001. There are 4 main adverse effects (ADRs) are vomiting, stomatitis, leukopenia, elevated liver enzymes.
Conclusions: The 5-day actinomycin D is an effective and safe regimen in the treatment of Methotrexate-resistant low risk gestational trophoblastic patients with βhCG levels ≤ 300 IU/l and FIGO score from 0-2 points
