Hypercalcemia of malignancy

Hypercalcemia generally develops as a late complication of malignancy; its appearance has grave prognostic significance.

Pathophysiology

It remains unclear, however, whether death is associated with hypercalcemic crisis (uncontrolled or recurrent progressive hypercalcemia) or with advanced disease.

Symptoms

Symptoms include central nervous system impairment such as delirium with prominent symptoms of personality change, cognitive dysfunction, disorientation, incoherent speech, and psychotic symptoms such as hallucinations and delusions, smooth muscle hypotonicity, and altered cardiovascular function.

Treatment is similar to the treatment of hypercalcemia plus treatment of the underlying malignancy.
