小细胞肺癌合并抗利尿激素异常分泌综合征研究进展

小细胞肺癌患者常合并抗利尿激素异常分泌综合征(SIADH),其发生目前认为主要是肿瘤细胞分泌及药物应用引起体内抗利尿激素增多,引起体内水钠代谢平衡紊乱,导致不同程度的低钠血症,临床症状多样,表现无特异性,尤其与肿瘤引起的症状类似,极易造成误诊、漏诊.治疗上在积极治疗原发肿瘤基础上,严格限水是有效和主要的方法,小细胞肺癌患者合并抗利尿激素异常分泌综合征预后相关研究结果不一致,多认为是预后不良的独立因子.

Syndrome of Inappropriate Antidiuretic Hormone Secretion in Small Cell Lung Cancer

Syndrome of Inappropriate Antidiuretic Hormone Secretion (SIADH) was a common complica-tion of small cell lung cancer (SCLC). Recent studies have suggested that the origin of this disease is related to seceration of tumor cells and application of medecine. The inappropriate antidiuretic hormone secretion can lead to disturbance of metabolism of water and sodium, resulting in hyponatremia. Because the symp-toms are atypical, the diagnosis is difficult. Many cases are misdiagnosed or misseddiagnosed. The primary tumor must be treated and the restriction of water intake is the main and effective method to deal with SIADH. Prognosis of SCLC patients with SIADH is poor in most reports.
