#4593 Excellent response to Ac-225 DOTATATE therapy in a patient with small cell lung cancer

Introduction: Peptide receptor radionuclide therapy (PRRT) is a validated treatment for patients with NETs overexpressing somatostatin receptors (SSTR). IHC analysis indicates that up to 50% of small cell lung cancer (SCLC) tumours are SSTR2 positive and thus can be targeted by SSR imaging and PRRT. Therapy with α-emitting radionuclides, such as Ac225, may offer several advantages over β-emitters by having higher energy transfer and more effective cancer cell death.

#4244 Cell-free DNA (cfDNA) methylation profiling for minimally invasive cancer detection in patients with Extra-Pulmonary NeuroEndocrine Carcinoma (EP-NEC)

Introduction: Robust biomarkers to aid clinical management of patients (pts) with EP-NEC are lacking. cfDNA methylation profiling has shown higher sensitivity/specificity than cfDNA genome profiling in diagnosing and classifying various cancers, including Small Cell Lung Cancer (SCLC).

#4150 Uncovering the role of netrins and DCC (deleted in colorectal cancer) in pancreatic neuroendocrine neoplasms (PNEN) tumorigenesis

Introduction: DCC functions as a tumor suppressor and is altered in various tumors, including neuroendocrine neoplasms. Netrin (NTN)-1 serves as the primary ligand for DCC. Operating as a dependence receptor, DCC induces apoptosis without NTN and promotes cell survival in its presence. In some cancers like small cell lung cancer and neuroblastoma, upregulation of NTN-3 rather than NTN-1 has been observed. However, the precise involvement of NTNs and DCC in PNEN remains unclear.
