摘　　要：Objective To evaluate the efficacy of medroxyprogesterone acetate(MA)plus metformin as the primary fertility-sparing treatment for atypical endometrial hyperplasia(AEH)and early-stage grade 1 endometrial adenocarcinoma(G1 EAC)and the recurrence rate after treatment.Methods Sixty patients(aged 20-42 years)with AEH and/or grade 1 EAC limited to the endometrium were enrolled prospectively and randomized into two groups(n=30)to receive oral MA treatment at the daily dose of 160 mg(control)or MA plus oral metformin(850 mg,twice a day)for at least 6 months.The treatment could extend to 12 months until a complete response(CR)was achieved,and follow-up hysteroscopy and curettage were performed every 3 months.For all the patients who achieved CR,endometrial expressions of IGFBP-rP1,p-Akt and p-AMPK were detected immunohistochemically.Results A total of 58 patients completed the treatment.After 9 months of treatment,23(76.7%)patients in the combined treatment group and 20(71.4%)in the control group achieved CR;two patients in the control group achieved CR after converting to the combined treatment.The recurrence rate did not differ significantly between the control group and combined treatment group(30.0%vs 22.7%,P>0.05).Ten(35.7%)patients in the control group experienced significant weight gain of 5.7±6.1 kg,while none of the patients receiving the combined treatment exhibited significant body weight changes.Compared with the control group,the patients receiving the combined treatment showed enhanced endometrial expressions of IGFBP-rP1 and p-AMPK with lowered p-Akt expression.Conclusion Metformin combined with MA may provide an effective option for fertility-sparing treatment of AEH and grade 1 stage IA EAC,and the clinical benefits of metformin for controlling MA-induced weight gain and promoting endometrial expressions of IGFBP-rP1 and p-AMPK while inhibiting p-Akt expression warrants further study.目的评估在子宫内膜不典型增生(AEH)或早期1级子宫内膜样腺癌(G1 EAC)患者中,使用醋酸甲地孕酮(MA)联合二甲双胍作为保留生育功能治疗的疗效和复发率,分析治疗后子宫内膜中IGFBP-rP1、p-AMPK和p-Akt的表达变化。方法前瞻性招募60名年龄在20~42岁之间的AEH和/或病灶局限于子宫内膜的1级EAC患者。患者被随机分为MA组(n=30)和MA加二甲双胍组(n=30)。对照组患者接受MA(口服160 mg,2次/d)治疗,联合组患者在口服MA治疗的基础上加用二甲双胍(口服850 mg,2次/d),治疗持续至少6个月,必要时可延长至12个月以达到完全缓解(CR),并每3个月进行一次随访宫腔镜检查和刮宫术。对于达到CR的患者,通过免疫组织化学方法检测子宫内膜组织中IGFBP-rP1、p-Akt和p-AMPK的表达。结果共有58名患者完成了治疗。在治疗第9个月时,联合治疗组中23例(76.7%)患者达到了CR;对照组中20例(71.4%)患者达到了CR,另外两例患者在将治疗改为二甲双胍联合MA治疗后也达到了CR。联合治疗组的复发率为22.7%,对照组为30.0%。对照组10名患者(35.7%)体质量增加5.7±6.1 kg,而在联合组患者体质量变化没有统计学意义。与对照组相比,联合治疗组子宫内膜组织中IGFBP-rP1和p-AMPK表达增加,p-Akt表达降低。结论MA和二甲双胍联合治疗可作为1级IA期EAC和AEH的保留生育功能治疗的有效方法,二甲双胍辅助治疗可以控制由MA引起的体质量增加,增加子宫内膜组织中IGFBP-rP1和p-AMPK的表达,同时抑制p-Akt的表达。该疗法在早期EAC和AEH治疗中的作用值得进一步研究。
