PURPOSE Cancer pain is the most serious symptom for patients, especially during their terminal phase, when palliative medicine is needed. Our study tried to verify the usefulness of single-shot intravenous administration of Samarium (Sm)-153EDTMP in patients with bone metastases (group-A, N=53, males=25, females=28, age range: 30-69 years), as well as to compare a series of variables, using as ...

BACKGROUND The effect of prior treatment with radiotherapy and/or chemotherapy on the myelotoxicity of samarium lexidronam (Sm 153) in patients with metastatic bone lesions and bone pain was described. METHODS Single-institution retrospective chart review of patients receiving Sm 153. The effect of Sm 153 on peripheral white blood cell (WBC), platelet counts, and change from baseline was calc...

Introduction:Targeted radionuclide therapy (TRT) has been demonstrated to be an effective therapeutic tool in patients with disseminated bone metastasis. TRT is generally performed with a single radionuclide. In this study we investigated the feasibility of combined TRT with a high-energy beta emitter (153Sm) and a low energy beta emitter (177Lu) in wistar...

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 Pain from skeletal metastases represents a major burden of advanced disease from solid tumors. Analgesic medications, bisphosphonates, hormonal agents, cytotoxic chemotherapy, and external beam radiotherapy are all effective treatments. However, patients often suffer from diffuse painful metastases and respond poorly to these standard therapies. Bone-seeking radionuclides can specifi...

Introduction: Bone pain palliation therapy is a mandate in handling end-stage cancer patients. The development of new ligands with higher stability, better pharmacokinetics and lower unwanted tissue uptakes (liver and GI) is still ongoing. Methods: In this work Lu-177 labeled (3-amino-1-hydroxypropane-1,1-di-yl)-bis-(phosphonate) (Lu-pamidronate; LuPAM ), and (3-amino-1-hydroxybutane-1,1-di-yl)...

Introduction: Various bone palliative therapeutic agents have been developed and widely used for bone metastasis such as Sm-EDTMP. In this study, production, quality control and biodistribution studies of a newly developed therapeutic compound have been presented followed by imaging studies in wild-type rodents. Methods: Sm-TTHMP was prepared starting from Sm-SmCl3, prepared by neutron activati...
