The management of hyponatremia in cancer patients: a practical view in Spain

Abstract

Hyponatremia is a common disorder among cancer patients and is associated with a poor prognosis in several malignancies. It is classified by volemic status into hypovolemic, euvolemic, and hypervolemic hyponatremia. Clinical history, physical examination, and blood and urine tests are important for a correct classification and diagnosis of hyponatremia, to assure correct management. Treatment of hyponatremia in cancer patients depends on the etiology of hyponatremia, as well as on the chosen therapy for the tumor. Supportive care is also a factor to be taken into account.
