Instead, cytokines released by the tumor and surrounding cells, such as macrophages and endothelial cells, act similarly to PTH and PTHrP to cause increased secretion of RANKL by osteoblasts, which stimulates osteoclast differentiation and increased resorption of bone. A review of cancer-related hypercalcemia suggests that up to 30% of all cancer patients develop the condition as a side effect of treatment. Glucocorticoids are effective in treating hypercalcemia due to some lymphomas, sarcoid, or other granulomatous diseases. There should be strong consideration for the involvement of a palliative care specialist, because HCM is a poor prognostic indicator, and correction of the HCM does not improve survival.39, 47. This final step is regulated by PTH, and calcitriol is the active form of vitamin D. Calcitriol increases serum calcium by causing increased calcium absorption in the intestines, increased calcium reabsorption in the kidneys, and stimulation of osteoblasts to reabsorb calcium from bone.1, 2, The parafollicular C cells of the thyroid gland secrete calcitonin. In contrast, hypercalcemia in the patient with a history of cancer presents in a … All oral calcium intake should be stopped.6, 61 Oral phosphate should be used when feasible, because intravenous phosphate has been associated with severe hypocalcemia, seizures, and acute renal failure.62, 63, Loop diuretics were historically recommended in the treatment of HCM once the patient was euvolemic, because they increase urinary calcium excretion. Strategies for treating hypercalcemia include: 1. Calcifediol is then hydroxylated at the 1 position in the kidney to form 1,25‐dihydroxycholecalciferol, or calcitriol. Hypercalcemic patients with an unsuppressed PTH level may have PHPT from a single parathyroid adenoma, multigland disease (more than 1 parathyroid adenoma), 4‐gland parathyroid hyperplasia associated with multiple endocrine neoplasia type 1, secondary hyperparathyroidism from chronic kidney disease, chronic lithium use, parathyroid carcinoma, or (rarely) familial hypercalciuric hypercalcemia.9 Of these, PHPT associated with a single adenoma is the most common cause of hypercalcemia in the general population and also can be seen in the cancer population, although it is less common. Anti-Tumor Therapy Treatment of the underlying malignancy with systemic therapy (e.g. Intravenous (IV) fluids, to dilute calcium i… Cancer Treatment and Research Communications. Available drugs for initial therapy include calcitonin, plicamycin, and etidronate; several additional investigational agents have shown promising efficacy in controlling hypercalcemia of malignancy. Cinacalcet for the Treatment of Humoral Hypercalcemia of Malignancy: An Introductory Case Report with a Pathophysiologic and Therapeutic Review. An Atypical Presentation of Primary Hyperparathyroidism in an Adolescent: A Case Report of Hypercalcaemia and Neuropsychiatric Symptoms Due to a Mediastinal Parathyroid Adenoma. 2020 Dec;9(23):8962-8969. doi: 10.1002/cam4.3594. Patient with low calcium may have an appropriate increase in their serum PTH as a compensatory mechanism. When the disease is not resectable, the calcimimetic cinacalcet can be used to partially suppress PTH secretion by the tumor.28, Patients with low PTH and high calcium most likely have HCM. Bisphosphonates inhibit osteoclastic bone resorption and are effective in the treatment of hypercalcemia due to conditions causing increased bone resorption and malignancy-related hypercalcemia. Bone mineral density demonstrates osteoporosis, with a T‐score of −2.6 in the forearm. Hypercalcemia in the patient with cancer can be due to benign causes or to HCM. 2A). Incidental hypercalcemia may be the first manifestation of an undiagnosed malignancy. His past medical history is significant for prostate cancer, which was treated 2 years ago with prostatectomy, and his current prostate‐specific antigen level is 0.0 ng/mL. Parathyroid cancer is also a possibility in patients who present with an extremely elevated PTH level—although it is rare. Therefore, pamidronate may be safe in patients with impaired kidney function, although adjustment of the dose may be required. These four tiny glands are situated behind the thyroid gland. Steroids inhibit osteoclastic bone resorption by decreasing tumor production of locally active cytokines, in addition to having direct tumorolytic effects. Español. Hypercalcemia caused by humoral effects and bone damage indicate poor outcomes in newly diagnosed multiple myeloma patients. The PTH level will act as a fork in the diagnostic road: in a patient with high PTH, the most likely diagnosis is primary hyperparathyroidism, and the next step will be to determine whether the patient has indications for surgical treatment (see below). In … If you have cancer, your doctor will discuss treatment options with you to help you determine the best ways to treat hypercalcemia. Response to therapy can last for 1 to 3 weeks.73, Zoledronic acid is easier to administer and has been shown to have a more efficacious response than pamidronate, with a higher proportion of patients achieving normalization within 7 to 10 days of treatment and a longer duration of effect.74 Bisphosphonates have been associated with nephrotoxicity, and care must be used, because patients with HCM usually have some degree of renal impairment.66 It is sometimes necessary to delay administration of these medications until after the patient has been rehydrated or to reduce the dose based on the estimated glomerular filtration rate. Unlike other forms of HCM, calcitriol‐mediated HCM tends to be associated with a normal to high phosphorus level.29. South Med J. Sheehan M, Tanimu S, Tanimu Y, Engel J, Onitilo A. Learn more. This could help with risks and symptoms relating to Hypercalcemia. As discussed above, these patients can become markedly hypovolemic. Bisphosphonates inhibit IL‐6 production by human osteoblast‐like cells, Neridronate and human osteoblasts in normal, osteoporotic and osteoarthritic subjects, Treatment of hypercalcemia of malignancy with intravenous etidronate: a controlled, multicenter study, Treatment of hypercalcemia of malignancy with bisphosphonates, Zoledronic acid is superior to pamidronate in the treatment of hypercalcemia of malignancy: a pooled analysis of two randomized, controlled clinical trials, Disodium pamidronate for treating severe hypercalcemia in a hemodialysis patient, Treatment of hypercalcaemia with pamidronate in patients with end stage renal failure, Incidence, risk factors, and outcomes of osteonecrosis of the jaw: integrated analysis from three blinded active‐controlled phase 3 trials in cancer patients with bone metastases, Bisphosphonates, hypercalcemia of malignancy, and osteonecrosis of the jaw, Denosumab and bisphosphonates: different mechanisms of action and effects, Accuracy of MDCT in predicting site of GI tract perforation, Denosumab for treatment of hypercalcemia of malignancy, The role of RANK‐ligand inhibition in cancer: the story of denosumab, The role of denosumab in the prevention of hypercalcaemia of malignancy in cancer patients with metastatic bone disease, Protracted hypocalcaemia following a single dose of denosumab in humoral hypercalcaemia of malignancy due to PTHrP‐secreting neuroendocrine tumor, The effects of calcitonin in hypercalcemia in patients with malignancy, Salmon calcitonin in the acute management of hypercalcemia, Regulation of calcitonin receptor by glucocorticoid in human osteoclast‐like cells prepared in vitro using receptor activator of nuclear factor‐B ligand and macrophage colony‐stimulating factor. Most recently, bisphosphonate drugs h… The majority of calcium is stored in the bone. Cancer induced hypercalcemia is treated using denosumab. Although there is no standard, any PTH greater than 20 pg/mL is often considered unsuppressed. In developed countries, it usually presents incidentally with an indolent course and is most often discovered from a screening serum calcium level obtained for other reasons.4, 5 Interestingly, with the advent of the electrolyte panel, which automatically includes a serum calcium level, the incidence of PHPT has increased. Hypercalcemia and Cancer: Differential Diagnosis and Treatment Jonathan Zagzag, MD, MPH1, Mimi I. Hu, MD2, Sarah B. Fisher, MD1 and Nancy D. Perrier, MD, FACS3 Abstract: Incidentally detected hypercalcemia usually presents in an indolent manner and is most likely caused by primary hyperparathyroidism. You may also need other treatments for hypercalcemia, including the following: Replacing fluids. If the disease is localized to a single adenoma on imaging, then a focused resection is planned. Too much calcium in your blood can weaken your bones, create kidney stones, and interfere with how your heart and brain work.Hypercalcemia is usually a result of overactive parathyroid glands. She was discharged on hospital day 10, at which point she was started on denosumab because of refractory hypercalcemia. Case Rep Oncol. (See \"Osteoclast inhibitors for patients with bone metastases from breast, prostate, and other solid tumors\".) This site needs JavaScript to work properly. Less common causes include excess calcitriol (1,25‐dihydroxyvitamin D) production by lymphomas.6 HCM occurs in 20% to 30% of patients who have advanced cancer, with a yearly incidence of 1% to 2% across all cancer types.6, 29, 36, 37 It is the most common cause of hypercalcemia in the hospitalized patient.7, 38 It is a poor prognostic sign, and patients with HCM have a mean survival of 2 to 3 months and an in‐hospital mortality of 6.8%.19, 39 With the exception of neuroendocrine tumors, most tumors are clinically evident when they cause HCM.6 Although any cancer can lead to HCM, the most common associated malignancies are solid cancers, such as lung, breast, head and neck, and urinary tract cancers. The most common benign cause is PHPT. The bioavailable calcium is unchanged and, in these patients, an ionized calcium level should be obtained.59 These patients typically are asymptomatic and have mild elevations in total calcium. The third most common cause of hypercalcemia is simply due to excessive doses of calcium carbonate. Replacing fluids lost through vomiting and urination. It presents indolently and is treated with surgery when necessary. Cancer-associated … Patients presenting with HCM are usually markedly hypovolemic and often have manifestations of renal and cardiac failure. eCollection 2020 Jan-Apr. This is because of polyuria secondary to calciuresis and also to decreased oral intake secondary to nausea and vomiting. Adequacy of resection of all hyperfunctional tissue is confirmed by using an intraoperative PTH measurement. A review of records demonstrates the presence of hypercalcemia since at least 3 years prior, with calcium levels ranging from 10.2 to 10.8 mg/dL. consequently, the MIP-1α and its cognate receptors may additionally serve as targets for the development of novel treatments to fight hypercalcemia. Another rare cause of HCM is pseudohypercalcemia caused by increased secretion of calcium‐binding immunoglobulins that occurs in patients with multiple myeloma. Although it is not renally cleared, the effect of denosumab is more pronounced in patients with renal failure, and dose adjustment may be necessary to avoid hypocalcemia.47. Polyuria is also common and, combined with decreased oral intake, can lead to hypovolemia. Learn about cancer, its causes, and its treatment. In contrast, hypercalcemia in the patient with a history of cancer presents in a … Treatment for hypercalcemia is based on a number of factors, including the condition of the patient and the severity of the hypercalcemia. Hypercalcemia Symptoms. Unsuppressed or inappropriately elevated PTH refers to a high PTH level in the setting of a high or high‐normal calcium level. Courtesy of Dr. Steven Waguespack. In contrast, hypercalcemia in the patient with a history of cancer presents in a wide range of clinical settings and may be severe enough to warrant hospitalization. … Paraneoplastic syndromes and bone metastasis are two main causes of lung cancer-related hypercalcemia (7,10,12). Furthermore, when elevated at presentation, PTHrP can be used as a biomarker to assess treatment response to therapy.40-42, Systemic secretion of PTHrP by malignant tumors is referred to as HHM. Increasing fluid intake and the use of diuretics has been standard practice. This should be a decision that includes the patient and a surgeon. The average adult consumes approximately 1000 mg of calcium in their diet, of which 500 mg is absorbed, and the intestines secrete 325 mg, leading to a net absorption of 175 mg daily, and the rest is excreted in the feces. Finally, hyperthyroidism, adrenal insufficiency, pheochromocytoma, and chronic immobility also can cause hypercalcemia through increased osteoclast activity.13, Once the diagnosis is made, the first step in the management of a patient in hypercalcemic crisis is to stabilize the patient with intravenous fluid resuscitation. Using bisphosphonates, osteoporosis drugs given intravenously (with a needle through the veins) that treat hypercalcemia due to cancer Using denosumab (XGEVA®), another bone-strengthening drug for patients with cancer-caused hypercalcemia who don’t respond to bisphosphonates Hypercalcemia of malignancy and new treatment options Hillel Sternlicht,1 Ilya G Glezerman1,2 1Division of Nephrology and Hypertension, Weill Cornell Medical College, 2Renal Service, Memorial Sloan Kettering Cancer Center, New York, NY, USA Abstract: Hypercalcemia of malignancy affects up to one in five cancer patients during the course of their disease. Patients may be able to treat their hypercalcemia simply by eating less calcium. Like bisphosphonates, osteonecrosis of the jaw also may occur with the use of denosumab.66 Other side effects include bone pain, nausea, diarrhea, and shortness of breath. Furthermore, the production of osteoprotegrin, an inhibitor of RANKL, is decreased. The patient was admitted to the hospital and treated with intravenous fluid resuscitation and calcitonin, and her mental status improved. Effective treatment of hypercalcemia is entirely dependent on the actual cause of a cat’s high blood calcium level. The ionized calcium level is also regulated by the pH of the serum. Clipboard, Search History, and several other advanced features are temporarily unavailable. Removal of the underlying cause is the definitive treatment for hypercalcemia, but this is not always immediately possible. Treatment is focused on fluid resuscitation and correction of the calcium level. Huang SY, Chen Y, Tan XR, Gong S, Yang XJ, He QM, He SW, Liu N, Li YQ. This includes treating the underlying cancer to lower calcium levels in the blood. Alendronate and risedronate are potent, third-generation bisphosphonates that ca… Barri Y, Knochel P. Hypercalcemia and electrolyte disturbances in malignancy. You might be … 2020 Jan. .. Zagzag J, Hu MI, Fisher SB, Perrier ND. If the PTH level does not drop after resection of a single suspected adenoma, then all 4 glands are examined intraoperatively. Patients with cancer who have hypercalcemia can be divided into 2 major groups: those with and those without an elevated PTH level. eCollection 2020. However, since hypercalcemia often occurs in patients whose cancer is advanced or has not responded to treatment, management of hypercalcemia is sometimes necessary. Be sure to drink at least eight cups of water each day. Hypercalcemia of malignancy (HCM) typically is associated with severe clinical signs and symptoms and is often an oncologic emergency.6 Ninety percent of all cases of hypercalcemia in patients with and without cancer are caused by either HCM or PHPT. After sufficient intravenous hydration, she started on zoledronic acid, which lowered her serum calcium back to the normal range. Hypercalcaemia, also spelled hypercalcemia, is a high calcium (Ca 2+) level in the blood serum. Substernal oxyphil parathyroid adenoma producing PTHrP with hypercalcemia and normal PTH level. Of course, sometimes treatment of hypercalcemia must begin before a diagnosis is made or before antineoplastic treatment has its effect. Hypercalcemia is a disorder commonly encountered by primary care physicians. Spread of cancer (metastasis) to your bones also increases your risk.
