Osteonecrosis of the jaw has also been associated with IV bisphosphonates and is more common in those receiving high-dose and prolonged therapy and in those who have undergone dental procedures while on therapy.42, Calcitonin is also used to acutely lower calcium levels. This guideline has been adapted for local use. Wright et al4 found that either pamidronate or zoledronic acid was administered only to 54.2% of patients with hypercalcemia of malignancy within 48 hours of diagnosis and to 67.8% of patients overall.

This binding of RANK/RANKL regulates osteoclastogenesis. The only malignancy it has been approved for use in is parathyroid carcinoma.28 Dialysis or continuous renal replacement therapy is usually reserved for hypercalcemia refractory to all of the above therapies.46,49. Contraindicated medications were continued for 2.8% of patients, and bisphosphonates were given to 72.2% of those with acute renal failure. Macrophage inflammatory protein 1α was found to be elevated in the bone marrow of patients with active myeloma, and it is known to stimulate osteoclastic formation in human bone marrow cells.5,16 Local cytokines can also be released in the setting of metastatic breast cancer bone lesions, such as transforming growth factor β, which stimulate local production of PTHrP.17, Extrarenal production of 1,25(OH)2D by the tumor accounts for approximately 1% of cases of hypercalcemia in malignancy.1 In normal vitamin D metabolism, stored vitamin D (25[OH]D) in the liver is converted to 1,25(OH)2D under the influence of PTH by renal 1-α-hydroxylase in the kidneys. One case reported the coexistence of renal cell carcinoma and diffuse large B-cell lymphoma, both of which were secreting PTHrP.29 There are also reports of concurrent primary hyperparathyroidism and humoral hypercalcemia of malignancy.30-32. 19(2): 558-567. 3. Furosemide blocks calcium reabsorption in the loop of Henle and increases urine output, which may necessitate increased saline administration, inducing further renal excretion of calcium.1, Two bisphosphonate agents were approved by the US Food and Drug Administration for the treatment of hypercalcemia of malignancy: pamidronate (Aredia) and zoledronic acid (Zometa).2-5 Bisphosphonate therapy should be initiated as soon as hypercalcemia is detected, because it takes 2 to 4 days to lower the calcium level. Zoledronic acid is given at 4 mg IV over 15 to 30 minutes.13, Bisphosphonates, unfortunately, have been associated with nephrotoxicity. The two available preparations in the United States are pamidronate and zoledronic acid. In cases where further anti-neoplastic therapy is not feasible, the decision to treat or not treat hypercalcemia should be made by careful exploration of the patient’s goals of care. However, additional therapies, especially for moderate to severe hypercalcemia, are essential when simultaneously treating the underlying malignancy. Hypercalcaemia of malignancy (HCM) is a condition which occurs in cancer patients and can be defined when the serum calcium level (corrected for albumin) is greater than 2.6 mmol/L or greater than the upper limit of normal (ULN) for a given reference value used in a lab. The following represents disclosure information provided by authors of this manuscript. Thus, understanding its mechanism of action is important. Presented at the European Multidisciplinary Cancer Congress, September 23-27, 2011, Stockholm, Sweden. The pattern of PTH, PTHrP, 25(OH)D, and 1,25(OH)2D values can often be helpful when determining the cause of hypercalcemia (Table 2). Prolia (denosumab) [package insert]. Treatment of hypercalcemia of malignancy (HCM) is briefly reviewed, available treatments are compared, and treatment guidelines are presented. Re-treatment Flash Update Sent July 29, 2011. PTH <1.6 pmol/l Non parathyroid cause. Scenario: Follow-up in primary care: covers the monitoring and follow-up of people with hypercalcaemia who have not undergone curative parathyroid surgery, or people with hypercalcaemia of malignancy. with malignancy, occurring in approximately 10-20% of patients with cancer. Previously, the proposed mechanism was direct destruction of bone by metastases or malignant cells. East Hanover, NJ: Novartis Pharmaceuticals Corp; 2015. Mild asymptomatic hypercalcemia (calcium, 10.5-11.9 mg/dL) may not need to be treated until after the work-up has been completed and a diagnosis has been established. The clinical manifestations of hypercalcemia can involve many body systems. Hypercalcemia of malignancy (HCM) typically is associated with severe clinical signs and symptoms and is ... up to date with current guidelines regarding screening for colorectal, breast, and other cancers appropriate for the pa-tient’s age, sex, and risk factors. Hudson, OH: Wolters Kluwer Health. Rehydration can be accomplished by intravenous administration of normal saline, at a rate of 200 to 500 mL/h or 2 to 4 L/d, depending on renal function, the baseline status of dehydration, and the severity of hypercalcemia. Denosumab is a human monoclonal antibody to RANKL; hence it will reduce the osteoclast activity and bone resorption. 2. Treatment of the underlying malignancy is always the primary goal of therapy. ASCO Author Services Cardiovascular effects include hypertension, shortened QT interval, cardiac arrhythmia, and vascular calcification. 2003;67:1959-1966. Hypercalcemia is most common in those who have later-stage malignancies and predicts a poor prognosis for those with it. The doctors concerned must make the management plan for an individual patient. One should exercise caution and administer smaller volumes of isotonic saline in patients with congestive heart failure or anuric renal failure, as they can become volume overloaded. Hypercalcemia is considered mild if the total serum calcium level is between 10.5 and 12 mg per dL (2.63 and 3 mmol per L). Renal effects include dehydration, polyuria, nephrolithiasis resulting from hypercalciuria, nephrogenic diabetic insipidus, and nephrocalcinosis. Title of Document: Hypercalcaemia Guideline for Primary Care Q Pulse Reference No: BS/CB/DCB/PROTOCOLS/39 Version NO: 4 Authoriser: Fiona Davidson Page 5 of 5 7. Because of the requirement for continuous intravenous infusion, gallium nitrate is not used frequently.2,7. Published online Hypercalcemia of malignancy is a severe complication of cancer that should be treated quickly and appropriately. We will request your mailing address on the next page. Management depends on the severity of calcium imbalance. 1,25(OH)2D causes increased intestinal absorption of calcium and enhances osteolytic bone resorption, resulting in increased serum calcium.18 Extrarenal production is most commonly seen with Hodgkin and non-Hodgkin lymphoma1 and has also been reported in ovarian dysgerminoma.19 Nonmalignant granulomatous diseases such as sarcoidosis and other inflammatory conditions can also produce hypercalcemia as a result of extrarenal 1,25(OH)2D production via autonomous 1-α-hydroxylase activity in tissue macrophages.20. Therapy There are multiple evidence-based guidelines for the treatment of adults with hypercalcemia of malignancy. Past medical history should include information about cardiac and … The most common cancers are lung cancer, multiple myeloma, and renal cell carcinoma. If the albumin is abnormal, the serum calcium should be corrected for the serum albumin using the formula in Table 1. Relationships may not relate to the subject matter of this manuscript. Asymptomatic patients with mild hypercalcemia (serum calcium level, 10.5-12 mg/dL) generally do not require immediate treatment. JCO Precision Oncology, ASCO Educational Book Normal ionized calcium levels are 4 to 5.6 mg per dL (1 to 1.4 mmol per L). In respiratory alkalosis caused by hyperventilation, the ionized calcium decreases acutely, and reductions in pH can cause the ionized calcium to rise acutely, both resulting in relatively rapid shifts.33 Repeat measurements of calcium should be done routinely to ensure these are not spurious results. Hydration with normal saline should be continued until the patient is fully resuscitated, serum calcium level is normal, and urine output is maintained at 200 mL/h.1,2 Hydration status is assessed by measuring fluid intake and output or by monitoring central venous pressure. ASCO Career Center PTHrP acts on osteoblasts, leading to enhanced synthesis of RANKL.13, Local osteolytic hypercalcemia accounts for 20% of cases1 and is usually associated with extensive bone metastases and skeletal tumor burden. Does previous head and neck irradiation increase the chance of multigland disease in patients with hyperparathyroidism?
