Withholding antihypercalcemic therapy may result in a life-threatening emergency such as coma and death. IV, intravenous; PTH, parathyroid hormone; SC, subcutaneous. Am Fam Physician. However, glucocorticoids can be used to enhance the effect of calcitonin by upregulating the cell-surface calcitonin receptors and creating new ones on the osteoclast.43 Calcitonin is usually dosed at 4 to 8 IU/kg subcutaneously every 6 to 12 hours.14 Interestingly, there is a case report of calcitonin use for 14 days without evidence of tachyphylaxis in a patient with bisphosphonate-resistant hypercalcemia of malignancy.44. However, aggressive hydration can exacerbate heart failure in elderly patients; thus, the use of hydration is limited in patients with congestive heart failure. bronchus, upper oesophagus), lymphoma, myeloma, kidney and bladder. Through direct mechanisms they induce osteoclast apoptosis, and through indirect mechanisms acting on the osteoblasts they can reduce osteoclastic bone resorption. Guidelines for the treatment of hypercalcemia associated with malignancy Lynne Nakashima, BSc(Pharm), PharmD Journal of Oncology Pharmacy Practice 2016 3 : 1 , 31-37 All rights reserved.1249 South River Road - Suite 202, Cranbury, NJ 08512. Hypercalcemia of malignancy occurs frequently in adult oncology patients (10 to 40%) but is rare (0.4 to 0.7%) in children . In response to hypercalcemia, calcitonin is secreted by the parafollicular C cells. Flash Update Sent July 29, 2011. The clinical manifestations of hypercalcemia can involve many body systems. … Stewart AF. This paper reviews the cancers associated with hypercalcemia and their proposed mechanisms, nontumor-mediated hypercalcemia, as well as diagnosis and treatment strategies for each condition. 5
19(2): 558-567. If there is increased interaction between RANK and RANKL, then there is more osteoclastic expression and more bone resorption.5,6, Calcium homeostasis is tightly regulated by many hormones, including parathyroid hormone (PTH), 1,25-dihydroxy vitamin D (1,25[OH]2D), calcitonin, serum calcium, and serum phosphorus.7,8 PTH is produced by the parathyroid glands. Gastrointestinal symptoms include nausea, vomiting, anorexia, weight loss, constipation, abdominal pain, pancreatitis, and peptic ulcer disease. The maximum effect generally occurs within 4 to 7 days after initiation of therapy. (May 01, 2016)
HHM is the most common mechanism of hypercalcemia in patients with cancer. In addition, excessively high serum calcium causes clinical manifestations that affect the neuromuscular, gastrointestinal, renal, skeletal, and cardiovascular systems.1 Malignancy is a common cause of hypercalcemia, particularly when bone metastases exist. Hypercalcemia is most common in those who have later-stage malignancies and predicts a poor prognosis for those with it. However, additional therapies, especially for moderate to severe hypercalcemia, are essential when simultaneously treating the underlying malignancy. 2020 Year in Review - Neuroendocrine Tumors, Steroids plus Exercise Reduce Fatigue in Patients with Advanced Cancer, Managing Bone Metastases Through a Multidisciplinary Approach, A Taxing Consequence: Taxane Acute Pain Syndrome, EGFR Inhibitor–Associated Papulopustular Rash, Barriers to Initiating Oral Oncolytics by Specialty Pharmacy or Payers Can Affect Patient Outcomes, HER2 Receptor Antagonist–Associated Cardiotoxicity, Management of Hypercalcemia of Malignancy, The Role of the Oncology Nurse Navigator in Improving Supportive Care, Best Practices in Patient Navigation - Second Issue: Supportive Care Edition. However, the etiology is not always mediated by malignancy. INTRODUCTIONTreatment for hypercalcemia should be aimed both at lowering the serum calcium concentration and, if possible, treating the underlying disease. 6. However, moderate to severe hypercalcemia (calcium > 12 mg/dL), especially when associated with severe renal or neurologic symptoms, requires prompt, often inpatient management. Therapy There are multiple evidence-based guidelines for the treatment of adults with hypercalcemia of malignancy. When compared directly, zoledronic acid was found to be more potent than pamidronate, but both are considered acceptable therapies.39 The median response duration was 32 days with zoledronic acid 4 mg IV and 18 days with pamidronate 90 mg IV. The most common cancers are lung cancer, multiple myeloma, and renal cell carcinoma. When associated with rhabdomyosarcoma, hypercalcemia tends to present later, with more therapy resistance (2,3). 2015;21:143-147. Hypercalcemia of malignancy can result from: humoral hypercalcemia of malignancy (characterized by tumor secretion of parathyroid hormone-related peptide [PTHrP]); local osteolytic hypercalcemia (characterized by local release of factors, including PTHrP, by bony metastases that promote osteoclast differentiation and function); calcitriol (1,25-dihydroxyvitamin D)-mediated hypercalcemia … Title of Guideline: Management of Hypercalcaemia of Malignancy Date of Submission: November 2015 Date of Review: November 2017 ... Hypercalcaemia of Malignancy: a Pooled Analysis of Two Randomizes, Controlled Clinical Trials. 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). 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.
It is important to understand the pathogenesis, work-up, and treatment options for hypercalcemia associated with malignancy so that timely intervention can occur. 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. Fluid replacement, however, is first-line therapy for those with acute renal insufficiency as a result of volume depletion. DOI: 10.1200/JOP.2016.011155 Journal of Oncology Practice
If the serum calcium is believed to be inaccurate, then ionized calcium can be used, but this also has its limitations and can be inaccurate. The maximum effect generally occurs within 4 to 7 days after initiation of therapy. Previously, the proposed mechanism was direct destruction of bone by metastases or malignant cells. The treatment of hypercalcemia will be reviewed here, with emphasis on the management of hypercalcemia … Central nervous system effects include lethargy, impaired concentration, fatigue, and muscle weakness. Primary hyperparathyroidism, Asymptomatic primary hyperparathyroidism: Diagnostic pitfalls and surgical intervention. 12, no. The optimal choice varies with the cause and severity of hypercalcemia.

Contraindicated medications were continued for 2.8% of patients, and bisphosphonates were given to 72.2% of those with acute renal failure. PTH-mediated causes of hypercalcemia also need to be considered in hypercalcemia associated with malignancy. Hypercalcemia is a common complication of various types of cancer, including squamous-cell carcinoma, multiple myeloma, T-cell lymphoma, and breast carcinoma. However, it is not recommended in severe renal impairment (serum creatinine > 4.5 mg/dL). Therapy focuses on methods to reduce serum calcium through increased calciuresis, decreased bone resorption, and reduced intestinal absorption of calcium. Zometa (zoledronic acid) [package insert]. It increases renal calcium absorption and decreases renal phosphorus absorption. (2001) Zoledronic acid is superior to pamidronate in the treatment of hypercalcemia of malignancy: a pooled analysis of two randomized, controlled clinical trials. 2-7 The incidence of cancer-associated hypercalcaemia is now falling because of earlier and prolonged use of bisphosphonates in cancer patients with metastatic bone disease. 1. However, 20% of patients with hypercalcaemia do not have bone metastases. Once intravascular volume has been restored, low-dose furosemide (20-40 mg intravenously) every 1 to 4 hours can be used to further lower the serum calcium level and/or prevent the development of volume overload from administration of normal saline. NCCN Guidelines and Compendium Updated. The zoledronic acid package insert recommends that in hypercalcemia of malignancy, patients with mild to moderate renal impairment before initiation of therapy (serum creatinine < 4.5 mg) do not need dose adjustment. Hypercalcemia of malignancy is a severe complication of cancer that should be treated quickly and appropriately. The albumin–calcium system is highly sensitive to pH, and changes in pH alter the fraction of calcium ions that are bound to albumin. • Malignancy • Vitamin D mediated – Toxicosis – Granulomatous disorders • Medications • Miscellaneous – Immobilization, hyperthyroid, adrenal insufficiency, acromegaly} Accounts for 80‐90% of cases 9 10. Today, hypercalcemia is most commonly diagnosed in asymptomatic patients, whereas clinical features previously were the earliest manifestations. 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. 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. Management depends on the severity of calcium imbalance.

Serum phosphorus should also be measured because hypercalcemia can be associated with both hyper- and hypophosphatemia. Ranges of serum calcium concentration are used to classify the severity of hypercalcaemia: Mild hypercalcaemia is an adjusted serum calcium concentration of 2.6–3.00 mmol/L. ASCO Meetings Subscribers
If the etiology is not clear with the above laboratory tests, and the diagnosis of multiple myeloma is in question, then serum and urine protein electrophoresis or immunofixation along with a skeletal survey is indicated. Therefore, the cornerstone of initial treatment of hypercalcemia in these patients is volume expansion with intravenous normal saline to increase the glomerular filtration rate and renal calcium excretion. Abbreviations: 1,25(OH)2D, 1,25-dihydroxy vitamin D; 25(OH)D, 25-hydroxy vitamin D; PTH, parathyroid hormone; PTHrP, parathyroid hormone–related peptide. Laboratory Evaluation of Hypercalcemia. Annals of Internal Medicine 2008 149 259 – 263. Treatment should be reserved for patients for whom the benefit outweighs the risk, and dose reduction should be used.5 In addition to bisphosphonate therapy, adequate hydration can enhance renal protection and help preserve renal function when compared with patients who were dehydrated and received bisphosphonates for hypercalcemia.40. Hypercalcaemia is a raised level of corrected calcium in the blood. In approximately 60% to 90% of patients, the serum calcium level normalizes within 4 to 7 days, and the response lasts for 1 to 3 weeks.2, Bisphosphonates inhibit bone resorption and decrease bone mineralization by disrupting osteoclast activity.2 The most common adverse reactions are renal toxicity, flulike symptoms, injection site reactions, hypocalcemia, hypophosphatemia, fatigue, muscle weakness, and constipation or diarrhea.4,5 Daily oral supplementation with 500 mg of calcium and a multiple vitamin containing 400 IU of vitamin D is recommended to prevent hypocalcemia.4,5, Denosumab (Prolia), a full human immunoglobulin G2 monoclonal antibody against RANKL, can be used to manage malignancy-associated hypercalcemia in patients with persistent hypercalcemia despite bisphosphonate treatment. It is the commonest life-threatening metabolic disorder in cancer patients, most frequently occurring in myeloma, breast, renal, lung and thyroid cancers. The total calcium level is low in patients with low levels of binding proteins (hypoalbuminemia) and higher in those with high levels of binding proteins. September 21, 2016, See accompanying commentaries on pages 433 and 435. Miacalcic (salcatonin) [package insert]. Hypercalcaemia Guidelines KMCC format v3 final.doc Page 3 of 7 1.0 Signs and symptoms of hypercalcaemia of malignancy Hypercalcaemia is defined as a serum calcium concentration of 2.65mmol/L(or higher) on two occasions, following adjustment for the serum albumin concentration. The result is both hypercalcemia and hypophosphatemia.1,5 However, unlike PTH, PTHrP does not increase 1,25(OH)2D and thus does not increase intestinal absorption of calcium and phosphorus. CancerLinQ Other symptoms include bone pain, arthritis, and osteoporosis. There have been several proposed mechanisms for hypercalcemia associated with malignancies, which include: humoral hypercalcemia of malignancy mediated by increased parathyroid hormone–related peptide (PTHrP); local osteolytic hypercalcemia with secretion of other humoral factors responsible for hypercalcemia; excess extrarenal activated vitamin D (1,25[OH]2D); PTH secretion, ectopic or primary; and multiple concurrent etiologies. The severity of hypercalcemia is classified into 3 categories based on the level of total serum calcium (Figure). Hydration with Normal Saline Followed by Low-Dose Furosemide. Editorial Roster Patients often require 1 to 2 L as an initial bolus and then maintenance fluids of 150 to 300 mL/h for the next 2 to 3 days or until they are volume replete. Usual supportive care for hypercalcemia includes removing calcium intake from any sources (eg, intravenous or oral calcium supplements), increasing oral free water intake, discontinuing medications and supplements that cause hypercalcemia (thiazide diuretics, lithium, vitamin D, calcium carbonate therapy), increasing weight-bearing ambulation/activities, and discontinuing sedative drugs and analgesics.1 Symptomatic patients whose serum calcium level exceeds 12 mg/dL or asymptomatic persons whose level exceeds 14 mg/dL should be immediately and aggressively treated with antihypercalcemic therapy: saline rehydration followed by loop diuretics, calcitonin, bisphosphonates, or denosumab.2,4 For the majority of cancer patients with HHM or local osteolytic hypercalcemia, intravenous bisphosphonates or subcutaneous/intramuscular calcitonin or subcutaneous denosumab can be used to inhibit osteoclast-mediated bone resorption. 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. This section addresses treatment options for hypercalcemia, including dose, frequency, and titration parameters; expected effects and anticipated time to resolution; special or target populations for specific therapies; and side effects and their management. The most effective strategy is treatment of the underlying malignancy. A practical approach to hypercalcemia. Denosumab in hypercalcemia of malignancy: a case series. Laboratory evaluations after hypercalcemia is established: Additional laboratory evaluations to consider if diagnosis is still uncertain: SPEP, UPEP serum-free light chains, serum and urine IFE, 2318 Mill Road, Suite 800, Alexandria, VA 22314, © 2021 American Society of Clinical Oncology.

Denosumab binds to RANKL (soluble protein essential for the formation, function, and survival of osteoclasts) and inhibits osteoclast activity, resulting in decreased skeletal-related events and tumor-induced bone destruction.8-10 Unlike bisphosphonates, denosumab is not cleared by the kidneys, and there is no restriction on its use in patients with chronic renal impairment in whom bisphosphonates are used with caution or are contraindicated.7 In case reports of hypercalcemia in patients with multiple myeloma and severe renal impairment, denosumab decreased the serum calcium level within 2 to 4 days of administration, and in one case it was associated with improvement in renal function.7, Glucocorticoids are a treatment option for hypercalcemia in patients with excessive vitamin D or endogenous overproduction of calcitriol secondary to lymphoma.2 In those conditions, agents such as oral prednisone (60 mg/d for 10 days) can be used or intravenous hydrocortisone (200 mg daily for 3 days), or equivalents.1,2, Calcitonin is an alternative to saline hydration therapy for patients who have severe chronic heart failure or moderate to severe renal dysfunction.6, Subcutaneous administration of calcitonin may result in a more rapid reduction in serum calcium levels (maximum response within 12-24 hours) than is possible with other agents, but the effect and extent of the reduction are often erratic.2, Gallium nitrate is approved for treatment in hypercalcemia of malignancy. 2. These are followed by breast and colorectal cancers, and the lowest rates were reported in prostate cancer.2 Thirty-day mortality was previously reported at 50%.3 However, a recent analysis showed a median length of stay of 4 days, and an in-hospital mortality rate of 6.8%.4. Hypercalcemia is usually detected initially as an elevation of total plasma calcium levels rather than ionized calcium levels. http://druginserts.com/lib/rx/meds/zometa-1, Calcium and Cancer: Of Evil Humors and Innocent Bystanders, Hypercalcemia of Malignancy: A New Twist on an Old Problem, Reasons to Reject Physician Assisted Suicide/Physician Aid in Dying, Breast Cancer in Women Older Than 80 Years, Developing Effective Communication Skills, Patient and Plan Characteristics Affecting Abandonment of Oral Oncolytic Prescriptions, The State of Oncology Practice in America, 2018: Results of the ASCO Practice Census Survey, The State of Cancer Care in America, 2017: A Report by the American Society of Clinical Oncology, Centers for Medicare and Medicaid Services: Using an Episode-Based Payment Model to Improve Oncology Care, Best Practices for Reducing Unplanned Acute Care for Patients With Cancer, Serum total calcium (recheck if only one measurement), 0.8 (4.0 − serum albumin) + serum calcium = total estimated calcium, Ionized calcium (if total estimated calcium is believed to be unreliable). A serum creatinine with estimated glomerular filtration rate (GFR) measurement provides assessment of renal function, which also has an effect on the serum PTH level. Rarely, vitamin A toxicity can result in hypercalcemia; thus serum vitamin A levels can be a consideration if other etiologies are not discovered. IV Pamidronate 60 to 90 mg in 250 mL NS over 1 hour OR 4.1. For the management of hypercalcaemia in malignancy, or hypercalcaemia in palliative patients, see separate guidance available at www.palliativecareguidelines.scot.nhs.uk. 1-3 Hypercalcemia may be associated with any malignancy type, but is more frequently observed in carcinomas of the breast, lung, kidney, head and neck. hypercalcemia associated with malignancies, which include: humoralhypercalcemiaofmalignancymediatedbyincreased parathyroid hormone–related peptide (PTHrP); local oste-olytic hypercalcemia with secretion of other humoral factors responsible for hypercalcemia; excess extrarenal activated vitamin D(1,25[OH] 2 D); PTH secretion, ectopicor primary; 1. Hypercalcemia can occur in those with malignancy and an additional etiology for hypercalcemia such as primary hyperparathyroidism or granulomatous diseases. Advertisers, Journal of Clinical Oncology Diel I, Body J, Stopec A, et al. An additional consideration is vitamin D intoxication. Normal ionized calcium levels are 4 to 5.6 mg per dL (1 to 1.4 mmol per L). Hypercalcemia can occur in up to 30% of persons with a malignancy.1 In severe cases, hypercalcemia can be associated with neurocognitive dysfunction as well as volume depletion and renal insufficiency or failure. Pamidronate is given at 60 to 90 mg IV over 4 to 24 hours. Patients should be adequately hydrated before administration of zoledronic acid, and a single dose of 4 mg IV should be given over no less than 15 minutes. Clinical manifestations of hypercalcemia vary according to the level of calcium in the blood. 9. The estimated yearly prevalence of hypercalcemia for all cancers is 1.46% to 2.74%; it is four times more common in stage IV cancer and associated with a poor prognosis. It occurs in approximately 10% of patients with cancer. Anti-Tumor Therapy Treatment of the underlying malignancy with systemic therapy (e.g. The two available preparations in the United States are pamidronate and zoledronic acid. 4. Hypercalcemia associated with cancer, Prevalence of hypercalcemia of malignancy among cancer patients in the UK: Analysis of the Clinical Practice Research Datalink database, Cancer-associated hypercalcemia: Morbidity and mortality. For hypercalcemia unresponsive to other measures. 2,3 Hematologically, the incidence of hypercalcemia is greatest with multiple myeloma. The following represents disclosure information provided by authors of this manuscript. Table 1. Narrative review: furosemide for hypercalcemia: an unproven yet common practice. A treatment approach for hypercalcemia of malignancy. Contact Us Zoledronic acid is given at 4 mg IV over 15 to 30 minutes.13, Bisphosphonates, unfortunately, have been associated with nephrotoxicity. Most patients with hypercalcemia associated with malignancy are dehydrated as a result of renal dysfunction induced by hypercalcemia and by decreased oral fluid intake resulting from nausea and vomiting. Aredia (pamidronate sodium) [package insert]. If the albumin is abnormal, the serum calcium should be corrected for the serum albumin using the formula in Table 1. The optimal therapy for hypercalcemia of malignancy varies according to the severity of hypercalcemia and the underlying causes. The list of tests for initial diagnostic workup and follow-up/surveillance has been updated.
