Hypocalcemia and hypomagnesemia in cancer patients.
The aim of this study was to evaluate the incidence of hypocalcemia and hypomagnesemia and the relationship between calcium and magnesium serum levels in 82 hospitalized cancer patients, 61 of whom were in the terminal phase of the disease. The frequency of hypocalcemia and hypomagnesemia was 13.4% and 17.1% respectively. The incidence of hypocalcemia in patients with hypomagnesemia was 28.6%, while in those with normal or high magnesium serum levels it was 10.3%. The lowest magnesium serum level was observed in hypocalcemic patients. It may thus be concluded that hypocalcemia and hypomagnesemia are a frequent complication of malignant tumors mostly in the terminal stage of the disease, and that even hypomagnesemia could contribute to the development of tumor-associated hypocalcemia.
