A 76-year-old man with bone metastases of prostate cancer diagnosed a year ago was admitted for relief of bone pain (visual analogue scale: 90%) most markedly in cervical spine and upper extremities due to skeletal metastases. His serum prostate specific antigen level was markedly increased (351 ng/ml). After documentation of sufficient tracer uptake in multiple bone metastases on whole-body 99...
effectiveness and complications of 188re-hedp in palliative treatment of diffuse skeletal metastases
introduction: bone metastases are the most common cause of cancer-related pain in various primary malignant tumors, most often, breast and prostate. 188re-hydroxyethylidene diphosphonate (188re-hedp) is a new and less expensive bone seeking radiopharmaceutical with favorable physical characteristics of the radionuclide such as short half life of 16.9h, maximal β energy of 2.1 mev with a 15% γ-c...
BACKGROUND: A study for pain relief therapy with 188Re-HEDP was done in patients with bone metastases secondary to breast and prostate cancer. MATERIALS AND METHODS: Patients received 1.3 or 2.2 GBq, in single or multiple doses. Platelets, white and red cells were evaluated during 11 weeks. Pharmacokinetic characterization was done from blood and urine samples for 5 patients along 24 hours. Uri...
The use of 188Re from an alumina-based 188W/188Re generator has been investigated for antibody radiolabeling. It was found that, with simple labeling techniques, 188Re can be used immediately after elution. The direct radiolabeling of intact antibodies with 188Re is described. Lyophilized antibody preparations have been reconstituted with 188Re taken directly from the generator at specific acti...
Liposomal doxorubicin (Lipo-DOX) has been widely and successfully used in chemotherapy for breast cancer patients. Since our previous studies found that 188Rhenium (188Re)-N,N-bis (2-mercaptoethyl)-N',N'-diethy-lethylenediamine (BMEDA)-labeled pegylated liposomes (188Re-liposomes) have radiotherapeutic potential in a colon cancer model, and little information is available to make a comparison o...
OBJECTIVE To investigate the role of 188Re in human sodium iodide symporter (hNIS) theranostic gene-mediated human glioma imaging and therapy in model mice. METHODS The human glioma cell line U87 was transfected with recombinant lentivirus encoding the hNIS gene under the control of cytomegalovirus promoter (U87-hNIS). The uptake and efflux of 188Re were determined after incubating the cells ...
The trihydroxamate bifunctional chelating agent (BCA), trisuccin, has been shown to be a potential ligand for radiolabeling of monoclonal antibodies (MAbs) with rhenium radioisotopes, through an indirect postconjugation approach. The use of this trihydroxamate BCA made it possible to prepare stable BCA-MAb conjugates in pure form that could be radiolabeled with carrier-free 188Re. The anti-TAG-...
Human head and neck squamous cell carcinoma (HNSCC) is usually treated by surgical resection with adjuvant radio-chemotherapy. In this study, we examined whether the radiopharmaceutical 188Re-liposome could suppress the growth of HNSCC followed by an investigation of molecular mechanisms. The orthotopic HNSCC tumor model was established by human hypopharyngeal FaDu carcinoma cells harboring mul...
188Re (Rhenium) is easily obtained from an in-house 188W/188Re generator that is similar to the current 99Mo/99mTc generator, making it very convenient for clinical use. This characteristic makes this radionuclide a promising candidate as a therapeutic agent. Polyethylenimine (PEI) is a cationic polymer and has been used as a gene delivery vector. Positively charged materials interact with cell...
