A case of hypercalcemia induced by tamoxifen in a patient with breast carcinoma metastatic to the bones is presented. The induction of the hypercalcemia may be secondary to the weak initial estrogenic effects of tamoxifen. Patients who are treated with tamoxifen and other antiestrogens should be monitored carefully for evidence of hypercalcemia. To the editor: To prove that tamoxifen causes hypercalcemia in advanced breast cancer, as has been suggested by Veldhuis (1) and others (2-4), would require that three criteria be met. The hypercalcemia should develop after tamoxifen therapy, reverse when tamoxifen is withdrawn, and be reinduced by tamoxifen rechallenge. In our prospective trial of tamoxifen in 30 premenopausal women with metastatic breast cancer, three developed hypercalcemia after 7, 9, and 28 days on tamoxifen therapy. The two who developed hypercalcemia most quickly had extensive preexisting bone involvement.

However, to date, this has not been documented with aromatase inhibitors. In a retrospective study survival after hypercalcemia in breast cancer patients.

Tamoxifen flare hypercalcemia an additional support for gallium nitrate usage. Parathyroid independent hypercalcemia is characterized by suppressed parathyroid hormone (PTH) in the presence of hypercalcemia. Well known causes and mechanisms are redistribution of calcium from the skeleton, by malignant diseases; inadequately increased intestinal calcium uptake mediated by increased vitamin D activity, and reduced renal elimination due to medications. Frequent and infrequent causes are discussed, and more recent mechanistic models presented in this review. Most hypercalcemic conditions are stable and in equilibrium between the different organs, whereas the utmost severe cases are characterized by rapid rising calcium levels and renal failure, resulting in a vicious circle where a disequilibrium state is developed. Management and treatment depends on the underlying condition and severity. The aim of this review is to discuss non-parathyroid hypercalcemic conditions as seen in the modern clinic, with a focus on areas where recent gain of knowledge has been achieved.
