Efficacy and safety of ibandronate in the treatment of opioid-resistant bone pain associated with metastatic bone disease: a pilot study.

Purpose: Bone metastases are associated with severe and sometimes intractable pain, compromising patient quality of life (QOL). This open-label pilot study investigated the effects of short-term intensive treatment with intravenous (i.v.

Cytostatic and apoptotic effects of bisphosphonates on prostate cancer cells.

Background: Bisphosphonates are potent inhibitors of bone resorption frequently used for breast cancer and myeloma-induced bone disease. Zoledronic acid has been recently shown to also reduce skeletal morbidity from prostate cancer.

Methods: We have investigated the biological effects of bisphosphonates on PC-3 cell survival (MTT assay and DNA content).

Response to alendronate in osteoporotic women previously treated with pamidronate.

Introduction: Different bisphosphonates have been shown to increase bone mineral density (BMD) and reduce the risk of fracture in osteoporotic patients. It is unclear how shifting from a treatment with one bisphosphonate to another will influence the evolution of BMD and bone turnover.

Methods: In the present study, we followed BMD (DXA, Hologic QDR1000) of the lumbar spine (BMDL) and of the total hip (BMDH), bone alkaline phosphatase (Ostase, Hibritech), and urinary collagen cross links (pyridinoline, deoxypyridinoline, Biorad) in 39 patients treated with IV pamidronate (60 mg/3 months) since at least 2 years and who were shifted to oral alendronate (10 mg/day, n=18) or left to IV pamidronate (n=21) for 2 more years.
