Background: Pulmonary carcinoid (PC) tumors represent approximately 25% of neuroendocrine tumors (NETs) and about 2% of all lung cancers. Despite the relative prevalence of PCs compared to all NETs, there is only one FDA indicated therapy (everolimus). Since regulatory approvals stem from publications that are often initially presented at scientific meetings, we sought to determine the frequency of presentations including PCs at two major international NET and lung cancer meet...

Background: Advanced small cell lung cancer (SCLC), extra-pulmonary neuroendocrine carcinoma (EP-NEC) and pancreatic adenocarcinoma (PDA) are rapidly progressive cancers characterized by unbridled replication stress. Patients with these malignancies possess dismal prognoses with limited options after initial first-line chemotherapy. These tumors rely on the integrity of DNA damage repair pathways to ensure genomic stability. The ataxia telangiectasia and Rad3-related (ATR) pro...

Background: Patients with advanced pheochromocytoma/paraganglioma (PPGL) or pancreatic neuroendocrine tumor (panNET) are in need of novel targeted therapies. Hypoxia-inducible factor 2α (HIF-2α) is one of the key oncogenic drivers in neuroendocrine tumors. Hypoxia signaling pathway alterations or other mechanisms that stabilize HIFs are common in some PPGLs and panNETs. Belzutifan (MK-6482), a HIF-2α inhibitor, has shown antitumor activity in advanced renal cell...
