Corrected calcium as a predictor of short-term mortality in patients hospitalized with cancer-related hypercalcemia

Abstract

Aims: Hypercalcemia is a malignancy-associated oncologic emergency, and evaluating short-term mortality in hospitalized patients is critical for predicting prognosis and guiding treatment. This study assessed 30-, 60-, and 90-day mortality rates in patients hospitalized for hypercalcemia and compared short-term survival according to the corrected calcium (dCa) level determined by receiver operating characteristic (ROC) analysis based on 90-day mortality. Methods: A total of 135 patients were included. ROC analysis was performed to identify the optimal dCa cutoff for predicting 90-day mortality. Patients were divided into low and high dCa groups, and survival was compared using the Kaplan–Meier method. A p-value <0.05 was considered statistically significant. Results: The overall 30-, 60-, and 90-day mortality rates were 34.1%, 48.1%, and 57%, respectively. ROC analysis identified a dCa cutoff of 12.6 mg/dl with 84.4% sensitivity and 41.4% specificity (AUC=0.637, 95% CI: 0.542–0.733, p=0.006). Patients with dCa <12.6 mg/dl had significantly higher survival at 30 days (83.3% vs. 59.6%, p=0.012), 60 days (69.4% vs. 45.5%, p=0.012), and 90 days (66.7% vs. 34.3%, p=0.002) than those with dCa≥12.6 mg/dl. Conclusion: Hypercalcemia requiring hospitalization is associated with high short-term mortality in cancer patients. A dCa level ≥12.6 mg/dl is a strong predictor of poor 30-, 60-, and 90-day survival. This threshold may serve as an early risk stratification marker, guiding closer clinical monitoring, treatment decisions, and palliative care planning.
