Abstract

Paraneoplastic syndromes are systemic disorders developing in response to any neoplasm and may have various clinical symptoms depending onthe affected organ system. Hypercalcemia, one of the renal cell carcinoma (RCC) - Related Paraneoplastic syndromes, occurs in approximately 20%of patients with RCC. Although clinical conditions such as paraneoplastic hypercalcemia and polycythemia are more common complications ofRCC, there are rarer paraneoplastic syndromes such as hepatic dysfunction, galactorrhea and Cushing’s syndrome. It has been reported that RCCaccounted for 2% of all cancers responsible for for Cushing’s syndrome and the symptoms associated with Cushing’s syndrome remited after surgicaltreatment. In our patient, although serum isolated adrenocorticotropic hormone, aldosterone and cortisol levels were normal, there was treatmentresistant hypokalemic metabolic alkalosis and this was not related to Cushing’s syndrome. Complete normalization of the clinical picture andlaboratory values after radical nephrectomy suggests that hypokalemic metabolic alkalosis may be a Paraneoplastic syndrome associated with RCC.

Özet

Paraneoplastik sendromlar, herhangi bir neoplazmaya yanıt olarak gelişen sistemik bozukluklardır ve etkilenen organ sistemine bağlı olarak çeşitli klinik semptomlara neden olabilir. Böbrek hücreli kanser (RCC) ile ilişkili Paraneoplastik sendromlardan biri olan hiperkalsemi, RCC hastalarının yaklaşık %20’sinde görülür. Paraneoplastik hiperkalsemi ve polisitemi gibi klinik durumlar RCC’nin daha sık görülen komplikasyonları olmasına rağmen, hepatik disfonksiyon, galaktore ve Cushing sendromu gibi daha nadir Paraneoplastik sendromlar da vardır. Paraneoplastik Cushing sendromu, RCC’nin Cushing sendromundan sorumlu tüm kanserlerin %2’sini oluşturduğunu ve Cushing sendromuyla ilişkili semptomların cerrahi eksizyondan sonra giderildiğini bildirmiştir (6). Hastamızda serum izole adrenokortikotropik hormon, aldosteron ve kortizol düzeyleri normal olmasına rağmen tedaviye dirençli hipokalemik metabolik alkaloz vardı ve bu Cushing sendromu ile ilişkili değildi. Radikal nefrektomi sonrası klinik tablonun ve laboratuvar değerlerinin tamamen normale dönmesi, hipokalemik metabolik alkolozun RCC ile ilişkili bir Paraneoplastik sendrom olabileceğini düşündürmektedir.
