Background: Gastroenteropancreatic neuroendocrine tumors (GEP-NETs), which frequently develop metastatic disease, represent an estimated 70% of NETs. There are limited treatment options with current standard therapies for well-differentiated aggressive grade 2 and grade 3 (Ki-67 index 15−55%) GEP-NETs; however, these may include somatostatin analogues; peptide receptor radionuclide therapy (PRRT); molecular targeted therapies (everolimus or sunitinib); chemotherapy; and ...

Background: Poorly differentiated neuroendocrine carcinoma (NEC) is an aggressive malignancy comprising both pulmonary and extrapulmonary primary sites. NEC includes both small cell lung cancer (SCLC) and large cell neuroendocrine carcinoma (LCNEC), as well as other neuroendocrine carcinomas arising from any primary organ. The optimal systemic therapy beyond first line platinum and etoposide is not established. There is a critical need to improve upon the median survival in th...

Background: Gastroenteropancreatic neuroendocrine tumors (GEP-NETs) represent an estimated 70% of NETs. GEP-NETs frequently develop metastatic disease with limited treatment options. For well-differentiated high grade 2 and 3 GEP-NETs, current therapies include peptide receptor radionuclide therapy (PRRT), somatostatin analogues, chemotherapy, cytoreduction, and molecular targeted therapies (everolimus, sunitinib). PRRT uses radiolabeled somatostatin analogues to selectively t...

Background: Peptide receptor radionuclide therapy (PRRT) is a form of targeted systemic radiopharmaceutical therapy that has been approved for treatment of somatostatin receptor-positive gastroenteropancreatic neuroendocrine tumors. Persistent hematologic dysfunction is a recognized potential long-term toxicity after PRRT, including the development of hematologic malignancies and persistent cytopenias. Therapy-related myeloid neoplasms (t-MN) are a well-recognized entity that ...
