JAMA Surg:双侧肾上腺意外瘤与库欣综合征有关

据7月22日在线发表于 JAMA Surgery的一项研究显示,与单侧肾上腺意外瘤相比,双侧肾上腺意外瘤患者出现亚临床库欣综合征的可能更大,但是此时手术已不再是最佳治疗方案。

尽管既往研究表明腹腔镜下手术切除单侧病变可改善亚临床库欣综合征,但是该治疗却是不足的,“对患有双侧肾上腺意外瘤的患者其治疗更为复杂,因为在确定手术切除之前需要确定皮质醇分泌过多的一侧,”Jesse D. Pasternak写道。由于缺乏切除双侧病变的病例,故外科医生需考虑这些患者肾上腺切除的风险,据统计高达18%的患者最后实施了双侧肾上腺切除术。

研究人员回顾分析了500名肾上腺疾病患者,135例肾上腺意外瘤患者中仅有2例(均为单侧肾上腺意外瘤患者)为肾上腺皮质癌。23例(17%)双侧肾上腺意外瘤患者的平均年龄为58.7岁,右侧病损平均大小为2.4㎝,左侧病损平均大小为2.8㎝。

5名(21.7%)双侧肾上腺意外瘤患者发生了亚临床库欣综合征,包括大部分激素分泌较高的双侧患者(激素分泌较多的双侧患者共7名),而112名单侧肾上腺意外瘤患者仅7名(6.2%)发生了亚临床库欣综合征(P = 0.009)。双侧病变且存在亚临床库欣综合征的患者中,无糖尿病患者,2名高血压患者,2名肥胖患者,平均随访时间为4.6年。4.3%的双侧患者存在嗜铬细胞瘤而19.6%的单侧患者存在嗜铬细胞瘤(P =0 .003)。两类患者高醛甾酮症的发病率相似,双侧为4.3%,单侧为5.4%。仅1例伴嗜铬细胞瘤的双侧病变患者接受了单侧切除术治疗。

研究人员还注意到用来确定高皮质醇自主分泌量的阈值的不精确及衡量结果的不明确阻碍了对无症状高醛甾酮症患者的清晰认识。

“因此,研究结果还强调,需要更多关于亚临床库欣综合征的数据以指导未来疾病的管理,包括双侧肾上腺意外瘤的手术指征,”他们写道。
