Why Does Lymphoma Cause Hypercalcemia

Why Does Lymphoma Cause Hypercalcemia - ;The etiology of hypercalcemia in non-Hodgkin lymphoma (NHL) has been most often attributed to either elevated serum levels of 1,25-dihydroxycholecalciferol (calcitriol) or parathyroid-related protein (PTHrP). In a single-center retrospective review, we evaluated the incidence of, and outcomes associated with, hypercalcemia in NHL. Adult T cell leukemia lymphoma is associated with hypercalcemia in 50 70 of patients with this disease but the mechanism of hypercalcemia is independent of vitamin D and is often associated with the expression of PTHrP 439 440 or other cytokines 441 443

;Jean E Mulder, MD. Literature review current through: Mar 2024. This topic last updated: May 26, 2022. INTRODUCTION. Hypercalcemia is relatively common in patients with cancer, occurring in approximately 20 to 30 percent of cases [ 1 ]. It is the most common cause of hypercalcemia in the inpatient setting. ;Non-Hodgkin lymphoma (NHL) is a heterogeneous group of hematologic malignancies that affect 2% to 3% of adults in the United States during their lifetime. 1 At some point, 7% to 34% of NHL patients will develop hypercalcemia as a result of their disease. 2, 3, 4, 5 The etiology of hypercalcemia in B-cell NHL is itself heterogeneous.

Why Does Lymphoma Cause HypercalcemiaSeveral major mechanisms are responsible for the development of hypercalcemia of malignancy, including PTHrP-mediated humoral hypercalcemia, osteolytic metastases-related hypercalcemia, 1,25-dihydroxyvitamin D mediated-hypercalcemia, and PTH-mediated hypercalcemia in patients with parathyroid carcinoma and extra parathyroid. Excessive secretion of PTHrP is the most common cause of hypercalcemia of malignancy It is also known as humoral hypercalcemia of malignancy HHM and accounts for about 80 of the cases It is usually seen in solid tumors and a few cases of non Hodgkin lymphoma

;Incidentally detected hypercalcemia usually presents in an indolent manner and is most likely caused by primary hyperparathyroidism. 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.
