GEPNETs UPDATE: Radionuclide therapy in neuroendocrine tumors.

PRRT
Samenvatting
Peptide receptor radionuclide therapy (PRRT) is a promising new treatment modality for inoperable or metastasized gastroenteropancreatic neuroendocrine tumors (GEPNETs) patients. Most studies report objective response rates in 15-35% of patients. Also, outcome in terms of progression free survival (PFS) and overall survival compares very favorably with that for somatostatin analogs, chemotherapy, or new, 'targeted' therapies. They also compare favorably to PFS data for liver-directed therapies. Two decades after the introduction of PRRT, there

Samenvatting
Peptide receptor radionuclide therapy (PRRNT) is a molecularly targeted radiation therapy involving the systemic administration of a radiolabelled peptide designed to target with high affinity and specificity receptors overexpressed on tumours. PRRNT employing the radiotagged somatostatin receptor agonists (90)Y-DOTATOC ([(90)Y-DOTA(0),Tyr(3)]-octreotide) or (177)Lu-DOTATATE ([(177)Lu-DOTA(0),Tyr(3),Thr(8)]-octreotide or [(177)Lu-DOTA(0),Tyr(3)]-octreotate) have been successfully used for the past 15 years to target metastatic or inoperable

Treatment with radiolabelled somatostatin analogues is a promising new tool in the management of patients with inoperable or metastasized neuroendocrine tumours. Symptomatic improvement may occur with (177)Lu-labelled somatostatin analogues that have been used for peptide receptor radionuclide therapy (PRRT). The results obtained with (177)Lu-[DOTA(0),Tyr(3)]octreotate (DOTATATE) are very encouraging in terms of tumour regression. Dosimetry studies with (177)Lu-DOTATATE as well as the limited side effects with additional cycles

Samenvatting
The primary treatment of gastroenteropancreatic neuroendocrine tumors (GEPNETs) is surgery with curative intent or debulking of the tumor mass. In case of metastatic disease, cytoreductive options are limited. A relatively new therapeutic modality, peptide receptor radionuclide therapy (PRRT) with radiolabeled somatostatin analogs, is currently available in a number of mostly European centers. Complete and partial responses obtained after treatment with [90Y-DOTA0,Tyr3]octreotide are in the same range as after treatment with

Quality of life (QOL) is an important outcome in cancer therapy. In this study, we investigated the QOL and symptoms after [(177)Lu-DOTA(0),Tyr(3)]octreotate ((177)Lu-octreotate) therapy in patients with inoperable or metastasized gastroenteropancreatic or bronchial neuroendocrine tumors

Treatment with radiolabeled somatostatin analogs is a promising tool in the management of patients with inoperable or metastasized neuroendocrine tumors. Symptomatic improvement may occur with all (111)Indium-, (90)Yttrium-, or (177)Lutetium-labeled somatostatin analogs used for peptide receptor radionuclide therapy. If kidney protective agents are used, the side-effects are few and mild, and the median duration of the therapy response is 30 and 40 months, respectively. Overall survival is several years from diagnosis. These data compare

Somatostatin receptor imaging with [(111)In-DTPA(0))octreotide has proven its role in the diagnosis and staging of gastroenteropancreatic neuroendocrine tumors. Treatment with radiolabeled somatostatin analogues is a promising new tool in the management of patients with inoperable or metastasized, well-differentiated neuroendocrine tumors. Symptomatic improvement may occur with all (111)In, (90)Y, or (177)Lu-labeled somatostatin analogues that have been used for peptide receptor radionuclide therapy. The results that were obtained with

PURPOSE:
There are few treatment options for patients with metastasized or inoperable endocrine gastroenteropancreatic (GEP) tumors. Chemotherapy can be effective, but the response is usually less than 1 year. Here, we present the results of treatment with a radiolabeled somatostatin analog, [177Lu-DOTA0,Tyr3]octreotate (177Lu-octreotate).
PATIENTS AND METHODS:
One hundred thirty-one patients with somatostatin receptor-positive tumors were treated with up to a cumulative dose of 600 to 800 mCi (22.2 to 29.6

Samenvatting
A new treatment modality for inoperable or metastasized gastroenteropancreatic tumors is the use of radiolabeled somatostatin analogs. Initial studies with high doses of [(111)In-diethylenetriaminepentaacetic acid (DTPA)(0)]octreotide in patients with metastasized neuroendocrine tumors were encouraging, although partial remissions were uncommon. Another radiolabeled somatostatin analog that is used for peptide receptor radionuclide therapy (PRRT) is [(90)Y-1,4,7,10-tetraazacyclododecane-N,N',N'',N'''-tetraacetic acid
