The presence of hypercalcemia was associated with higher serum levels of \u03b22 microglobulin, creatinine, phosphorus, uric acid, procollagen I N\u2010terminal peptide, \u03b2\u2010carboxy\u2010terminal cross\u2010linking telopeptide of type I collagen and osteocalcin, lower serum levels of hemoglobin, parathyroid hormone (PTH), and advanced ISS and R\u2010ISS stages. Multivariate analysis showed that serum PTH, hemoglobin, creatinine, and uric acid levels were the main factors affecting hypercalcemia.
