One of the current therapeutic approaches in the treatment of osteoblastic bone metastases uses the affinity of Samarium ((153)Sm) ethylene-diamine-tetramethylene phosphonic acid (EDTMP) for bone areas of bone turnover. As Samarium EDTMP is a beta-emitter, the radiotherapy contributes to osteoblastic bone lesion control over time. To date, the safety and effectiveness of Samarium therapy have n...
radionuclide therapy is widely used as an effective modality in the management of bone pain. the main indication for this treatment is symptomatic bone metastases, confirmed by bone scintigraphy. we present a case of small cell lung cancer (sclc) stage t4n2m1b, with a good metabolic response to systemic therapy and radiotherapy of the primary tumor and locoregional disease, which became metabol...
Developing new bone pain palliation agents is a mandate in handling end-stage cancer patients around the world. Possibly, Lu-177 ethylenediaminetetramethylene phosphonic acid (177Lu-EDTMP) is a therapeutic agent which can be widely used in bone palliation therapy. In this study, 177Lu-EDTMP complex was prepared successfully using synthesized EDTMP ligand and 177LuCl3. Lu-177 chloride was obt...
متاستاز استخوان یک پی آمد مهم ناشی از سرطان هایی هم چون پروستات، سینه، کلیه،کبد و ... می باشد .این سرطان ها به ویژه سرطان سینه و پروستات رابطه تنگاتنگی با درد استخوان دارند. متاستاز استخوان در نتیجه ی یک فرایند مخرب پیچیده بین سلول های سرطانی و سلول های میزبان اتفاق می افتد که منجر به حمله ی سلولی، گسترش غیرطبیعی و تحریک فعالیت سلول های اوستئوبلاست (استخوان ساز) و اوستئوکلاست (استخوان خوار) می ...
introduction: porphyrins are interesting derivatives with low toxicity, tumor avidity and rapid wash-out suggested as potential radiopharmaceuticals in radiolabeled form. in this work we report, synthesis, radiolabeling, quality control, stability, partition coefficient determination and biodistribution studies of 153sm-5,10,15,20-tetrakis(4-methoxyphenyl) porphyrin (153sm-4-mpp) in wild-type r...
OBJECTIVE To assess the therapeutic efficacy and toxicity of samarium-153-ethylenediaminetetramethylene phosphonic acid ((153)Sm-EDTMP) and pamidronate disodium in patients with painful metastatic bone cancer. SUBJECTS AND METHODS Eighteen patients with histopathologically confirmed malignancy and multifocal bone metastases were randomized into two equal groups of 9 patients each. Group A was...
Background: The formalism recommended by Task Group 60 (TG-60) of the American Association of Physicists in Medicine (AAPM) is applicable for β sources. Radioactive biocompatible and biodegradable 153Sm glass seed without encapsulation is a β- emitter with a short half life and delivers a high dose rate to the tumor in the millimeter range. In this work the dosimetry parameters of the ...
Radionuclide therapy is widely used as an effective modality in the management of bone pain. The main indication for this treatment is symptomatic bone metastases, confirmed by bone scintigraphy. We present a case of small cell lung cancer (SCLC) stage T4N2M1b, with a good metabolic response to systemic therapy and radiotherapy of the primary tumor and locoregional disease, which became metabol...
background: owing to its favourable decay characteristics 177lu [t1/2= 6.71 d, eβ(max)= 497 kev] is an attractive radionuclide for various therapeutic applications. ethylene diamine tatramethylene phosphonate (edtmp) is one of the most widely used ligands which form stable complexes with various radionuclides and all the complexes. materials and methods: enriched 176lu2o3 was dissolved in 0.1 n...
