To relieve pain associated with multiple bone metastases radiopharmaceutical method of treatment is of great importance--the use of beta-emission isotope of strontium chloride-89 (metastron). Passing through the human skeletal system, strontium-89 accumulates in areas of high mineral density, which is it typical for osteoblastic metastases. In our institution in the frames of a randomized trial in 90 patients with metastatic hormone-resistant prostate cancer it was carried out systemic radiotherapy with strontium-89 chloride as a stage of complex treatment...

We report a case of tumor regression of multiple bone metastases from breast carcinoma after administration of strontium-89 chloride. This case suggests that strontium-89 chloride can not only relieve bone metastases pain not responsive to analgesics, but may also have a tumoricidal effect on bone metastases.

The administration of a radionuclide in unsealed source whose radiation will destroy cells that have selectively accumulated product is called radiometabolic therapy. The management of bone pain is a major problem, particularly in cases of breast or prostate where the presence of metastases can remain compatible with long-term survival of cancer patients. In this context, the radiometabolic therapy reduces the pain secondary to bone metastases, in association or not with analgesics. This technique is rarely prescribed as first-line...

BACKGROUND: Although the use of Sr-89 chloride in the treatment of patients with prostate and breast cancer has been widely reported, little information is available about its use for other malignancies. Here, we retrospectively analyzed the clinical profile of Sr-89 chloride in various patients with painful bone metastases. METHODS: Entry criteria were a pathologically proven malignancy, clinically diagnosed multiple bone metastases, and adequate organ function...

INTRODUCTION: Metastron ((89)SrCl(2)) is a radiopharmaceutical currently used for bone pain palliation in several countries since the long half-life of (89)Sr (50.5 days) favors wider distribution than other radioisotopes approved for this application, which have shorter half-lives. Strontium-89 is not ideal for bone pain palliation due to its high energy beta(-) particle emission [E(beta(max))=1.49 MeV] and is also difficult to produce in large quantities. A (170)Tm [T(1/2)=128.4 days, E(beta(max))=968 keV, E(gamma)=84 keV (3...

INTRODUCTION: Bisphosphonates have been used to treat Paget's disease, osteoporosis, and cancer metastases to the bone. The cancer chemotherapeutic potential of a first-generation bisphosphonate, etidronic acid, was evaluated by using MCF-7 human breast cancer cells. METHODS: In vitro cytotoxicity of etidronic acid to MCF-7 cells was estimated on the basis of clonogenicity assays, while cell cycle effects were determined by using flow cytometry. Mutagenicity of etidronic acid was detected by using denaturing high-pressure liquid chromatography analysis of cellular DNA amplified by PCR with primers for exons 5 through 8 of the human p53 gene...

Strontium-89 (Sr-89) alone or with concurrent chemotherapy has a role in the treatment of patients with prostate cancer (PCP). The schedules for repeated doses of Sr-89 or for concurrent chemotherapy is undetermined. The objective of this study was to measure the effective half-life (Te) of Sr-89 using a detector available in a nuclear research facility. Blood and urine samples obtained from PCP treated with Sr-89 (Metastron, Amersham, U.K.) were measured for radioactivity with a High Pure Germanium (HPGe) detector in a gamma spectrometry system (Eurisys, France)...

Spinal cord compression (SCC) is a devastating complication of metastatic cancer. We investigated the potential beneficial effect of two palliative therapies--strontium-89 (Metastron) and the nitrogen-containing bisphosphonate olpadronate--on the incidence of SCC in hormone-refractory prostate cancer (HRPC) metastatic to the skeleton. We retrospectively studied 415 patients with histologically proven prostate cancer who underwent bone scintigraphy at the time of diagnosis and were followed up at the Leiden University Medical Center between 1990 and 1999...

BACKGROUND: In the United States in 2000, 180,400 new cases of prostate carcinoma were expected to occur, with 31,900 men expected to die from this illness. In addition, prostate carcinoma is the cause of over half a million disability-adjusted life-years. This study summarizes the current body of published literature about the economics of prostate carcinoma. METHODS: The authors used a MEDLINE-based literature review for relevant articles from 1990 to the present...

An analysis of prospectively collected data from 75 patients with bone metastases secondary to prostate cancer who were treated with strontium-89 injection in a single centre over a 10-year period, is presented. The surrogate role of markers of disease progression (haemoglobin and prostate specific (PSA) antigen levels; number of bone scan-positive sites), symptomatic factors (analgesic intake; number of painful bone sites) and history of prior external radiotherapy, were analysed to determine whether any parameters had a predictive effect on the success of strontium-89 treatment...

Strontium-89 is a pure beta-emitting radioisotope, a chemical analogue of calcium, and it is therefore avidly concentrated by areas of high osteoblastic activity. Selective uptake and prolonged retention at sites of increased bone mineral turnover provide precise bone lesions targeting. 89Sr chloride (commercialised as Metastron) is typically administered in a single 150 MBq parenteral dose. Its radioactive emission poses very little radioprotection concerns. Overall, studies show pain relief in up to 80% of patients, of which 10 to 40% became effectively pain free...

Although bone pain from osteoblastic metastases can be ameliorated 50% to 80% of the time by use of intravenously or orally administered radiopharmaceuticals, we cannot accurately predict who will or will not respond. The radiopharmaceuticals containing phosphorus-32, strontium-89 (Metastron), rhenium-186, samarium-153 lexidronam (Quadramet), and tin-117m are effective, but we do not know which of these is the most efficacious or the safest. Toxicity includes mild-to-moderate pancytopenia and an occasional brief flare of pain, and treatment of patients with disseminated intravascular coagulation must be avoided because it may predispose the patient to severe thrombocytopenia...

93 patients with hormone refractory metastatic prostate cancer were entered on a prospective study to measure reduction in pain and changes in quality of life (QoL) after the administration of 150 MegaBequerel (MBq) Strontium-89 (Sr-89). QoL was assessed using a validated instrument, the Functional Living Index - Cancer (FLIC) questionnaire. Pain response was measured using the Radiation Therapy Oncology Group scoring system. Overall there was limited QoL improvement over 3 months following Sr-89. However, in the 53 patients (63%) achieving pain responses, QoL did significantly improve within 6 weeks of receiving Sr-89 compared to patients with stable or worsening bone pain, and this was independent of other parameters that might influence QoL outcomes, such as performance status, baseline PSA and extent of skeletal disease (P = 0...

This retrospective study evaluated the toxicity and efficacy of strontium-89 chloride (Metastron, Amersham) in 94 patients with painful bone metastases of prostate cancer (117 injections of 150 MBq) and compared the efficacy of treatment in patients with moderate and extensive bone involvement. The predictive value of flare response with regard to analgesic response was also studied. High-grade leukothrombopenias were observed after only 5% of injections. An improvement in quality of life was obtained in 65% of cases, a decrease in pain in 78% (31% complete response) and a reduction of analgesics in 60%...

Pain palliation with bone-seeking radiopharmaceuticals is an effective and cost-effective management tool in patients with advanced cancer metastatic to bone. Strontium-89 ((89)Sr) (Metastron) and samarium-153 ((153)Sm) EDTMP (Lexidronam) are licensed for use in patients in the United States. Patients with a positive bone scan using technetium 99m methylene diphosphonate ((99m)Tc MDP) are eligible for treatment, and indications and contraindications for use are now well defined. The evidence in the literature now suggests that the radiopharmaceuticals can significantly reduce pain and analgesic requirements, can improve quality of life, can reduce lifetime radiotherapy requirements and management costs, and may slow the progression of painful metastatic lesions...
