Prednisolone in the treatment of severe malignant hypercalcaemia in metastatic breast cancer: a randomized study.
To determine the effect of prednisolone on severe hypercalcaemia in women with metastatic breast cancer, 30 patients with serum ionized calcium above 1.60 mmol l-1 (reference range 1.15-1.35 mmol l-1) entered a randomized trial. Performance status before entry to the trial and survival time after hypercalcaemia were also noted. All patients received 4 l of isotonic saline daily and 80 mg intravenous furosemide three times daily for 2 d; thereafter they received 3 l of isotonic saline daily and 80 mg furosemide twice daily for 6 d. Fifteen patients were randomized to receive prednisolone, 25 mg orally, three times daily for 8 d. Serum ionized calcium decreased significantly in both groups, but most markedly in the prednisolone group. The median difference was 0.28 mmol l-1 (95% confidence interval (CI), 0.09-0.52) on day 4 and 0.21 mmol l-1 (95% CI, 0.12-0.44) on day 8. In seven prednisolone-treated patients serum ionized calcium normalized, compared to none in the control group (Fisher's exact test; P = 0.028). No severe adverse effects were observed. Prior to detection of hypercalcaemia all patients were severely immobilized, primarily due to bone pain. Only 10 patients were still living after 3 months. Prednisolone, furosemide and rehydration is superior to furosemide and rehydration alone in severely hypercalcaemic patients with metastatic breast cancer in whom immobilization appears to be an early warning sign of life-threatening hypercalcaemia. The short survival time was not influenced by prednisolone.
