[Analysis of 18 breast cancer patients with hypercalcemia].
A total of 91 breast cancer patients died of advanced and recurrent breast cancer at the Osaka Teishin Hospital from 1986 to 1996. There were 18 cases (19.8%) among them showing hypercalcemia (serum corrected Ca > or = 11.0 mg/dl). These 18 cases were analyzed to determine the incidence of hypercalcemia and to find a more effective treatment. All these patients had multiple bone metastases during their clinical course, and six patients (33.3%) had pathologic bone fracture just before the occurrence of hypercalcemia. Their common symptoms were general fatigue, gastrointestinal symptoms, renal dysfunction or neurological symptoms. There was no definitive correlation between clinical signs and serum calcium values. Among various therapies, the use of pamidronate disodium (Aredia) in combination with hydration, steroid and calcitonin was found to be the most effective treatment for hypercalcemia. The survival time from the diagnosis of hypercalcemia in the patients undergoing treatment with Aredia was significantly better than without it (p < 0.01). This suggests that Aredia should be effective and useful for advanced breast cancer patients with hypercalcemia.
