Hyponatremia (HN), defined as a serumsodium lower than 135 mmol/l, is themost common electrolyte disorder inhospitalized patients. Etiology isheterogeneous and a large differenceexists in terms of symptoms andtreatments. The aim of this study is todetermine the incidence of HN in aTertiary Cancer Center evaluatingpossible influence in terms of prognosisand length of hospitalization.
This study includes all cancer patientshospitalized at our Institution fromJanuary 2015 to December 2015 for allcauses otherwise than HN. We analyzedretrospectively data regarding HN andcorrelation to age, sex, staging,histology. Survival distribution wasestimated by Kaplan-Meyer method,differences in probability of survivingwere evaluated by chi-square test.
Patients were affected by lung cancer in21.7%, breast cancer in 19.5%,colorectal cancer in 13.0% (others in45.8%) [Fig.2]. Most patients had StageIV disease (93.4%), male 44.7%, female54.3%. Median age was 62.9 years.Concomitant diagnosis of SIADH wasperformed in 4 patients (8.8%).
HN represents a frequent occasionalfinding in hospitalized cancer patients,although in most cases it’s of milddegree. SIADH represents a smallpercentage of cases. In our experienceHN is not associated to dischargedelays. Moderate and severe HN arerelated with advanced stage disease withpoor prognosis. Independently by theunderlying disease, moderate andsevere HN identify a particular group ofpatients with poor prognosis, probablyreflecting very advanced disease andpalliative care needs.
Resolution of HN after specifictreatments was observed in 19 patients(41.3%). Median lenght of hospitalizationwas 10.7 days, without significantdifferences for patients who correctedHN or not, except to patients with SIADHtreated with tolvaptan (7.25 days). OSwas lower in patients withmoderate/severe HN versus mild (2.72vs 6.81 months) [Fig.3].
A total of 1.071 patients were included inthe analysis. 243 (22.7%) with at leastone episode of HN. 197 (81.1%) showedmild hyponatriemia (135-130 mmol/l), 44(18.1%) moderate (130-125 mmol/l), 2(0.8%) severe (< 125 mmol/l) [Fig.1].
Mortality rate was significantly lower inpatients with corrected HN compared tonot (52.6 vs 81.5%; p: 0.08), while nostatistically significant difference wasobserved in OS (2.89 vs 2.63 months; p:0.85) [Fig.4].

DA RICORDARE ………
• Le terapie “target “ possono aumentarne la incidenza
• Si associa a sintomi che aumentano la durata di degenza
• Importante l’approccio multidisciplinare per una corretta
diagnosi di SIADH (non sottovalutare valori di Na inferiori
alla norma!)
• La pronta correzione dei valori di Na impatta sulla prognosi
