Two kinds of uterine artery perfusion chemotherapy plus embolization for the treatment of ectopic pregnancy：a single center, randomized, double-blind and controlled study / 介入放射学杂志

ABSTRACT

Objective To evaluate the clinical efficacy and safety of two kinds of uterine artery perfusion chemotherapy plus embolization (UACE) in treating ectopic pregnancy (EP). Methods A single center, randomized, double-blind, controlled clinical trial was carried out at authors hospital. A total of 50 cases of EP patients were randomly and equally divided into the study group (perfusion chemotherapy of MTX and 5-FU plus embolization therapy) and the control group (perfusion chemotherapy of pure MTX plus embolization therapy). After UACE, the serumβ-HCG value, the clinical healing time and the tubal patency rate were determined at different time, and the adverse events were recorded. The results were statistically analyzed by using t test, and χ2 test, and the data were compared between the two groups. Results One patient in both groups was excluded from the study. In the remaining 48 patients, one patient of the control group failed to respond the treatment, so the overall cure rate was 97.9%. The differences in the main effect of treatment method and the time interaction of the serum β-HCG values between the two groups were not statistically significant (P > 0.05), while the difference in the time effect between the two groups was statistically significant (P 0.05). The tubal patency rate of the study group and the control group was 76.2%and 78.9%respectively, and no statistically significant difference existed between the two groups (P > 0.05). The adverse events in both groups were mild, and the occurrence of the adverse events in the study group and the control group was 58.3% and 26.1% respectively, and the difference between the two groups was statistically significant (P <0.05). Conclusion Two kinds of interventional methods have the same clinical curative effect. However, the incidence of adverse events in the control group is lower than that in the study group. Therefore, in treating ectopic pregnancy perfusion chemotherapy with MTX only is recommend.
