Hypercalcemia can occur in up to 30% of persons with a malignancy. In severe cases, hypercalcemia can be associated with neurocognitive dysfunction as well as volume depletion and renal insufficiency or failure. Individual risk of hypercalcemia depends on the underlying type and stage of malignancy.
Why does RCC cause hypercalcemia?
Increased prostaglandins have been reported as a cause for hypercalcemia in patients with RCC by stimulating bone resorption. In these cases, nonsteroidal inflammatory drugs may be effective in reducing calcium by inhibiting prostaglandin production by the tumor.
What is the first line treatment for hypercalcemia?
Intravenous bisphosphonates are the treatment of first choice for the initial management of hypercalcaemia, followed by continued oral, or repeated intravenous bisphosphonates to prevent relapse.

How long can a person live with hypercalcemia?
Unfortunately, cancer-related hypercalcemia has a poor prognosis, as it is most often associated with disseminated disease. Eighty percent of patients will die within a year, and there is a median survival of 3 to 4 months.
