Targeted Radionuclide Therapy
Targeted radiotherapy is an evolving and promising modality of cancer treatment. The killing of cancer cells is achieved with the use of biological vectors and appropriate radionuclides. Among the many advantages of this approach are its selectiveness in delivering the radiation to the target, relatively less severe and infrequent side effects, and the possibility of assessing the uptake by the...
متن کاملPeptide receptor radionuclide therapy.
On their plasma membranes, cells express receptor proteins with high affinity for regulatory peptides, such as somatostatin. Changes in the density of these receptors during disease, for example, overexpression in many tumors, provide the basis for new imaging methods. The first peptide analogues successfully applied for visualization of receptor-positive tumors were radiolabeled somatostatin a...
متن کاملRadionuclide therapy of hepatocellular carcinoma
Hepatocellular carcinoma (HCC) is a malignant tumour of the hepatocyte. It is a common malignancy worldwide and causes almost half a million deaths annually. Asia is a high risk area. Although surgery (hepatectomy or liver transplantation) is the main form of curative treatment, the majority of patients are not eligible for surgery due to extent of tumour and dysfunction of liver. Radiopharmace...
متن کاملRadionuclide therapy of adrenal tumors.
Adrenal tumors arising from chromaffin cells will often accumulate radiolabeled metaiodobenzylguanidine (MIBG) and thus are amenable to therapy with I-131 MIBG. More recently, therapy studies have targeted the somatostatin receptors using Lu-177 or Y-90 radiolabeled somatostatin analogs. Because pheochromocytoma (PHEO)/paraganglioma (PGL) and neuroblastoma (NB), which often arise from the adren...
متن کاملDevelopmental trends in targeted radionuclide therapy of neuroendocrine tumors
Neuroendocrine tumors (NETs) constitute a heterogeneous group of neoplasms including carcinoids, pancreatic neuroendocrine tumors, pituitary tumors, medullary thyroid carcinoma and phaeochromocytomas. The symptoms and the outcome of NETs differ considerably between patients depending on several factors. By labelling tracers with a radioisotope, the tracer acts as a ...
