Objective To investigate the effect of levonorgestrel intrauterine sustained-release system (LNG-IUS) combined with mifepristone in the treatment of adenomyosis.
Methods A total of 94 patients with adenomyosis admitted to our hospital were randomly divided into control group and observation group, with 47 cases in each group. The control group was treated with LNG-IUS alone, while the observation group was treated with LNG-IUS combined with low-dose mifepristone. All patients were followed up for 4 months. The serum carbohydrate antigen 125 (CA125), dysmenorrhea Visual Analogue Scale (VAS), changes of menstrual volume and results of B ultrasonography were compared before and after treatment, and the clinical efficacy and treatment safety were evaluated.
Results After treatment, the serum CA125, dysmenorrhea VAS score, menstrual amount, uterine volume and endometrial thickness of the two groups decreased significantly compared with treatment before(P < 0.05). Compared with the control group, the above indexes of the study group decreased more significantly (P < 0.05). The total effective rate was significantly higher than that of the control group (95.74% vs. 80.85%, P < 0.05). There were only a few mild adverse reactions, and higher safety in the two groups.
Conclusion LNG-IUS combined with low-dose mifepristone can significantly reduce serum CA125 level, improve clinical symptoms in patients with adenomyosis, and has higher safety.
