Zoledronic acid is prescribed to reduce bone resorption and improve bone remodeling and has recently been used to treat breast cancer. A female patient had bone-metastatic breast cancer complicated by osteonecrosis of the jaw and gingival squamous cell carcinoma (SCC) after receiving zoledronic acid. This 28-year-old patient was diagnosed with HER2-positive invasive breast cancer and underwent ...

PURPOSE Breast cancer patients with bone metastases are commonly treated with chemotherapeutic agents such as doxorubicin and zoledronic acid to control their bone disease. Sequential administration of doxorubicin followed by zoledronic acid has been shown to increase tumor cell apoptosis in vitro. We have therefore investigated the antitumor effects of clinically relevant doses of these drugs ...

BACKGROUND Zoledronic acid is an important osteotropic compound used in combination with anticancer agents to reduce the incidence of hypercalcemia and skeletal morbidity in patients with advanced breast cancer and bone metastases. Ineffectiveness of anticancer drugs during chemotherapy is a frequently observed situation in cancer chemotherapy. The resistance of tumor cells to more than one cyt...

Background. Loss of bone density with androgen deprivation therapy for prostate cancer is well recognized. We assessed the effects of quarterly infusion of zoledronic acid on bone mineral density (BMD) and markers of bone turnover over a one-year period in men receiving gonadotropin-releasing hormone analog (GnRH-a) for prostate cancer. Methods. 41 subjects were randomly assigned to treatment w...

PURPOSE The commercial availability of zoledronic acid, a third generation bisphosphonate, prompted us to evaluate the modifications in angiogenic cytokines levels after a single i.v. infusion of this drug. EXPERIMENTAL DESIGN Thirty consecutive cancer patients with scintigraphic and radiographic evidence of bone metastases were treated with a single infusion of 4 mg of zoledronic acid before...

BACKGROUND Bisphosphonates interfere with the mevalonate pathway and inhibit the prenylation of small GTP-binding proteins such as ras and rap. We hypothesized that zoledronic acid would synergistically inhibit T24 bladder cancer cell growth in combination with fluvastatin and paclitaxel. METHODS Increasing doses of fluvastatin, zoledronic acid, and paclitaxel were investigated as single agen...

Osteonecrosis of the jaw (ONJ) has been associated with the use of pamidronate and zoledronic acid. ONJ was assessed prospectively since July 2003 in 202 patients with multiple myeloma (MM) who received bisphosphonates since April 1995. Fifteen patients (7.4%) developed ONJ. The median time of exposure to bisphosphonates was 39 months for patients with ONJ compared to 28 months (p=0.048) for pa...

BACKGROUND Ovarian suppression plus tamoxifen is a standard adjuvant treatment in premenopausal women with endocrine-responsive breast cancer. Aromatase inhibitors are superior to tamoxifen in postmenopausal patients, and preclinical data suggest that zoledronic acid has antitumor properties. METHODS We examined the effect of adding zoledronic acid to a combination of either goserelin and tam...

Skeletal complications of cancer decrease health-related quality of life. Bisphosphonates can prevent skeletal-related events. We collected resource use data prospectively for 930 patients alongside a multinational trial of zoledronic acid versus pamidronate for patients with metastatic multiple myeloma or breast cancer and > or =1 bone lesion. Country-specific unit costs were assigned to count...
