Peptide Receptor Radionuclide Therapy and clinical associations with renal and hematological toxicities and survival in patients with neuroendocrine tumors: an analysis from two U.S. medical centers.

Purpose: Renal and hematological toxicity are side effects and dose-limiting factors of Peptide Receptor Radionuclide Therapy (PRRT). We aimed to assess the changes in renal and hematological function and associations with survival in neuroendocrine tumor (NET) patients treated with PRRT.

Methods: A retrospective cohort of 448 NET patients treated with either Lu-DOTATATE or Y-DOTATOC were followed for changes of renal and hematological function.

Liver Resection for Gastroenteropancreatic Neuroendocrine Tumors with Extrahepatic Disease.

: Although survival outcomes for neuroendocrine liver metastases (NETLM) are improved with liver-direct therapies (LDT), including hepatic debulking and nonsurgical trans-arterial embolization, the benefit is less established in the setting of concurrent extrahepatic disease (EHD). We performed a population-based study to characterize the rates of LDT being performed for NETLM with EHD patients and whether LDT is associated with survival outcomes. : Patients with NETLM and EHD were identified using the California Cancer Registry database merged with data from the California Office of Statewide Health Planning and Development between 2000 and 2012.

Liver-Directed Therapy in Neuroendocrine Neoplasms Metastatic to Both Liver and Bone.

Bone metastases from gastroenteropancreatic neuroendocrine neoplasms (GEPNENs) have been associated with poor prognosis, but it is unclear whether patients with concurrent bone metastases who receive liver-directed therapy (LDT) would derive survival benefit. The California Cancer Registry dataset, merged with data from the California Office of Statewide Health Planning and Development, was used to perform a retrospective study of GEPNENs metastatic to both liver and bone between 2000 and 2012. A total of 203 patients were identified.

Baicalein activates 5' adenosine monophosphate-activated protein kinase, inhibits the mammalian target of rapamycin, and exhibits antiproliferative effects in pancreatic neuroendocrine tumors in vitro and in vivo.

Background: The mammalian target of rapamycin inhibition has been shown to prolong progression-free survival in patients with pancreatic neuroendocrine tumors. The natural compound baicalein indirectly inhibits the mammalian target of rapamycin, but it is unknown if baicalein exhibits such effects at physiologically achievable concentrations or exhibits synergy.

Methods: Pancreatic neuroendocrine tumor cell lines were cultured with baicalein, everolimus, and/or a synthetic 5' adenosine monophosphate-activated protein kinase activating agent alone and in combination.
