胸腔病例(三八五)小細胞肺癌合併異位性庫欣氏症

摘要


異位性庫欣氏症(ectopic Cushing's syndrome, ECS)為小細胞肺癌第二常見(1-5%)的腫瘤附屬症候群(paraneoplastic syndrome)。而異位性庫欣氏症的病灶8-20%為小細胞肺癌,其次為肺類癌(carcinoid tumor)或胰臟、胸腺等部位的神經內分泌瘤。小細胞肺癌合併異位性庫欣氏症的預後表現不佳,對於化療治療的效果有限,感染與血栓栓塞的機會也較高。此類病人多以電解質不平衡與肌肉無力表現,較少能見月亮臉、軀幹型肥胖等典型庫欣氏症表現。除了腫瘤的治療以外,可用Etomidate、Fluconazole、Mifepristone等藥物治療高皮質醇血症(hypercortisolism)。
