[Is hyponatremia a prognostic marker of survival for lung cancer?].

Hyponatremia is frequently observed on the basis of syndrome of inappropriate antidiuretic hormone hypersecretion (SIADH) in patients suffering from lung cancer. This electrolyte imbalance is associated with higher mortality and morbidity. If hyponatremia influences survival of lung cancer remains controversial. In the current study we retrospectively analysed if survival is directly impacted by hyponatremia and evaluated if hyponatremia is a prognostic marker for lung cancer. © Georg Thieme Verlag KG Stuttgart · New York.
