[Clinical study of high intensity focused ultrasound ablation combined with GnRH-a and LNG-IUS for the treatment of adenomyosis].
Objective:To investigate the clinical effect of dysmenorrhea in patients with adenomyosis treated by high intensity focused ultrasound(HIFU)ablation combined with gonadotropin-releasing hormone agonist(GnRH-a)and levonorgestrel-releasing intrauterine system(LNG-IUS).Methods:From April 2012 to December 2015, 477 cases of adenomyosis patients with dysmenorrhea were treated by HIFU in the Third Xiangya Hospital. Among them, some patients were treated with HIFU alone, some of them were treated with HIFU combined with GnRH-a and(or)LNG-IUS, thus were classified as H group, H+G group, H+M group and H+G+M group. The improvements of clinical results were compared among the four groups and the influencing factors of HIFU treatment for adenomyosis were also analyzed.Results:During the follow-up period, the overall effective rates of the treatment decreased with time, 3 months 89.4%(345/386), 12 months 84.0%(221/263), 24 months 74.2%(98/132), and the overall recurrence rate was 12.9%(39/303). The significant difference in the curative at 3 months[H group 83.7%(170/203), H+M group 95.0%(95/100), H+G group 100.0%(43/43), H+G+M group 96.8%(30/31)], 12 months[H group 79.4%(123/155), H+M group 93.2%(69/74), H+G group 11/12, H+G+M group 15/17], and 24 months[H group 68.0%(51/75), H+M group 96.4%(27/28), H+G group 6/12, H+G+M group 15/15]after HIFU treatment and recurrence rate[H group 19.0%(29/153), H+M group 3.3%(3/90), H+G group 19.4%(6/31), H+G+M group 4.5%(1/22)]were observed among the four groups(P<0.05). Pairwise comparison further showed that, in 3 months after the treatment, the effect of H group was significantly lower than those of H+M group and H+G group(P= 0.003,P=0.005); in 12 months after the treatment, the effect of H group was significantly lower than that of H+M group(P=0.006); while in 24 months after treatment, the effect of H group was significantly lower than that of H+G+M group(P=0.005), and the effect of H+G group was lower than that of H+G+M group(P= 0.001); and the recurrence rate of H group was significantly higher than that of H+M group(P<0.008). In patients of group H, the effect of HIFU was related to uterine size, the effect of patients with large uterine volume was significantly higher than that of small volume of uterine of patients(P=0.017,OR=2.739, 95%CI: 1.200- 6.251); with increasing of age, the improvement of dysmenorrhea had a increasing trend(P<0.05).Conclusions:HIFU combined with GnRH-a and(or)LNG-IUS could improve the treatment effect in relief of dysmenorrhea. Based on our results, individual treatment protocol should be selected for different patients.
