UNLABELLED Intensification of the conditioning regimen with a radioactively labeled anti-CD66 antibody is feasible before allogeneic stem cell transplantation. The use of radioimmunotherapy may deliver a significant dose of radiation to the kidneys. We therefore studied the incidence and clinical picture of bone marrow transplantation (BMT) nephropathy in our patients receiving radioimmunothera...

Hepatocellular carcinoma (HCC) is the most common primary liver tumor and one of the fifth most common tumors worldwide. In this article we report the results of in vivo studies of potential anticancer agent "[188Re] rhenium-ImDendrim" derived from [188Re]rhenium-nitro-imidazole-methyl -1,2,3-triazol-methyl-di-(2-pycolyl)amine as radioactive ligand loaded 5th generation poly-L-lysine denrimer (...

Radioisotope-labelled lipiodol has been used in the therapy of liver cancer. Recently a lipiodol solution of 188Re-labelled diaminedithiol (DD) has been reported to show a high uptake in the liver cancer. We synthesized long-chain alkyl DD derivatives to improve their uptake and retention in tissue. As the length of the alkyl chain increased, tissue uptake and retention also increased due to hy...

background: recent pre-clinical and clinical studies indicate that irradiation in the dose range of 15 to 30 gy can reduce rate of restenosis in patients who have undergone an angioplasty. the use of filled balloon with radioactive solution was proposed as one of the possible intravascular irradiation techniques. materials and methods: the monte carlo n-particle transport code (mcnp4b) was used...

BACKGROUND: Radiosynovectomy is a type of radiotherapy used to relieve pain and inflammation from rheumatoid arthritis. In this study, 188-Rhenium (188Re) colloids were characterized by physical and biological methodologies. This was used to assess which parameters of the kit formulation would be the basis in the development of a more effective radiopharmaceutical for synovectomy. Intraarticula...

BACKGROUND The aim of this initial study was to evaluate the clinical and radiological effectiveness of radioembolization (RE) using 188Re-Human Serum Albumin (HSA) microspheres in patients with advanced, progressive, unresectable primary or secondary liver cancers, not suitable to any other form of therapy. MATERIAL/METHODS Overall, we included 13 patients with 20 therapy sessions. Clinical ...

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...

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...

PURPOSE This work aims to develop, validate and optimize the radiolabeling of Starch-Based Microparticles (SBMP) by 188Re and 68Ga in the form of ready-to-use radiolabeling kits, the ultimate goal being to obtain a unique theranostic vector for the treatment of Hepatocellular Carcinoma. METHODS Optimal labeling conditions and composition of freeze-dried kits were defined by monitoring the rad...
