Peptide receptor radionuclide therapy (PRRT) is an effective MRT (molecular radiotherapy) treatment, which consists of multiple administrations of a radiopharmaceutical labelled with 177Lu or 90Y. Through sequential functional imaging a patient specific 3D dosimetry can be derived. Multiple scans should be previously co-registered to allow accurate absorbed dose calculations. The purpose of thi...

The purpose of this systematic review was to investigate the effects of therapeutic radiopharmaceuticals in patients with different types of advanced neuroendocrine tumour (NETs). A literature search was carried out in MEDLINE and EMBASE from January 1998 to November 2010. The Cochrane Library (to Issue 10, 2010) and the Standards and Guidelines Evidence Inventory of Cancer Guidelines, includin...

Radionuclides are needed both for nuclear medicine imaging as well as for peptide-receptor radionuclide therapy (PRRT) of neuroendocrine tumors (NET). Imaging is important in the initial diagnostic work-up and for staging NETs. In therapy planning, somatostatin receptor imaging (SRI) is used when treatment is targeted at the somatostatin receptors as with the use of somatostatin analogues or PR...

Neuroendocrine tumours (NETs) are very rare diseases characterised by a high degree of histological and clinical heterogeneity. They can be silent (even producing some hormones) or clinically evident as a result of local growth and/or hormonal production. The diagnostic and therapeutic approach to patients with NETs should be multidisciplinary. A medical oncologist should coordinate a group of ...
