Abstract:
Objective To compare the therapeutic efficacy of sequential therapy with gonadotropin releasing hormone agonist(GnRH-a)combined with dienogest(DNG)versus DNG alone in patients with adenomyosis.Methods A retrospective analysis was conducted on clinical data from 129 patients diagnosed with adenomyosis by ultrasound and MRI between August 2020 and December 2023.Among them,60 patients received sequential therapy with GnRH-a followed by DNG(combination group)and 69 patients received DNG monotherapy(monotherapy group).There were no significant differences in baseline characteristics,including age,incidence of dysmenorrhea,incidence of menorrhagia,uterine volume,and type of adenomyosis between the two groups(P>0.05).The combination group received subcutaneous injections of leuprorelin3.75 mg every28 d for3 to 6 cycles,followed by oral DNG 2 mg/d for more than 3 months.The monotherapy group received oral DNG 2 mg/d alone for more than 3 months.Treatment outcomes and adverse reactions were compared between the two groups.Results The median duration of DNG treatment was 16.0(10.2,26.0)months in the combination group and13.0(6.0,23.0)months in the monotherapy group.The difference between the two groups was not statistically significant(Z=-1.587,P=0.113).Both groups showed a significant reduction in dysmenorrhea as measured by the Visual Analogue Scale(VAS)score,a significant decrease in serum CA125 levels,and a significant increase in hemoglobin levels after treatment compared to before treatment(all P<0.001).There were no significant differences between the two groups(P>0.05).Regarding uterine volume,the combination group showed a trend toward reduction after treatment[146.3(77.6,250.4)cm3 vs.118.4(82.4,233.4)cm3,Z=0.272,P=0.785],while the monotherapy group showed a significant increase in uterine volume compared to before treatment[162.9(110.8,256.0)cm3 vs.187.6(123.7,276.2)cm3,Z=2.945,P=0.003].The incidence of irregular vaginal bleeding in the combination group[50.0%(30/60)]was lower than that in the monotherapy group[75.4%(52/69),χ2=8.914,P=0.003].Conclusions Both sequential therapy with GnRH-a combined with DNG and DNG monotherapy are effective in relieving dysmenorrhoea,reducing CA125 levels,and increasing hemoglobin levels in patients with adenomyosis.However,sequential therapy is associated with a lower incidence of irregular vaginal bleeding compared to monotherapy and demonstrates a potential advantage in controlling uterine volume growth.
