In a retrospective study survival after hypercalcemia in breast cancer patients has been investigated. A group of 72 patients were treated with bisphosphonate APD [3-(amino-1,1-hydroxypropylidene)bisphosphonate] and third-generation amino-containing bisphosphonates between January 1980 and October 1992. A median survival of 4.5 months was found. In a multivariate analysis, four independent prognostic factors for survival have been found: the interval between first relapse and hypercalcemia, sites of metastases at the moment of hypercalcemia, primary treatment, and the level of serum alkaline phosphatase. Patients with a "flare" reaction on tamoxifen treatment and patients with a normal serum alkaline phosphatase level and bone metastases only had a prolonged survival. Hypercalcemia associated with visceral metastases carried a very poor prognosis. The level of serum calcium in this series of patients was no prognostic indicator for survival.
在一项回顾性研究中,对乳腺癌患者高钙血症后的生存情况进行了调查。1980年1月至1992年10月期间,一组72例患者接受了双膦酸盐APD[3-(氨基-1,1-羟基亚丙基)双膦酸盐]和第三代含氨基双膦酸盐治疗。发现中位生存期为4.5个月。在多变量分析中,发现了四个影响生存的独立预后因素:首次复发与高钙血症之间的间隔、高钙血症时的转移部位、初始治疗以及血清碱性磷酸酶水平。他莫昔芬治疗出现“flare”反应的患者以及血清碱性磷酸酶水平正常且仅有骨转移的患者生存期延长。伴有内脏转移的高钙血症预后极差。该系列患者的血清钙水平并非生存的预后指标。
