Targeted radionuclide therapy for neuroendocrine tumours.
نویسنده
چکیده
Evidence supporting the potential contribution of targeted radiotherapy to the management of neuroendocrine tumours is now strong. Acting systemically, this is an effective option for patients with inoperable or multi-site disease. Toxicity is generally low, being limited to reversible myelosuppression and theoretical nephrotoxicity. Prerequisites for treatment success include demonstration of high tumour uptake relative to non-target tissues on quantitative diagnostic radionuclide imaging and stable haematological and biochemical function. In addition to (131)I metaiodobenzylguanidine therapy, which is now well established, there is growing interest in radiolabelled peptide therapy using a range of somatostatin receptor analogues such as (90)Y DOTATOC and (90)Y lanreotide. The results of clinical experience are summarised and the direction for future research is discussed.

Developmental 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 ...
متن کاملTargeted radionuclide therapy for neuroendocrine tumours: principles and application.
Neuroendocrine tumours comprise a group of neoplasms with variable clinical behaviour. Their growth and spread is often very slow and initially asymptomatic, and thus they are often metastatic at the time of diagnosis and incurable by surgery. An exciting therapeutic strategy for cytoreduction, both for stabilisation of tumour growth and inhibition of hormone production, is the use of targeted ...
متن کاملNew medical strategies for midgut carcinoids.
Patients with well-differentiated neuroendocrine tumours of the gastrointestinal tract often present with metastases and hormonal symptoms. These patients can be palliated by interventional tumour reduction and medical treatment with somatostatin analogues; no effective chemotherapy is available. Radionuclide therapy via somatostatin receptors is one new therapeutic alternative. The recognition...
متن کاملOptimising structural imaging of neuroendocrine tumours in the molecular imaging age
Aim To provide an educational update on structural imaging appearances of neuroendocrine tumours (NET), in the age of molecular imaging. PET/CT with Ga-68 DOTA-TATE and F-18 fluorodeoxyglucose (FDG) is providing new understanding of neuroendocrine tumours including patterns and heterogeneity of disease. This is also providing new insights of structural imaging findings including CT and MRI. It ...
