#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.

#4282 A first-in-human phase I trial with antibody drug conjugate ADCT-701 in neuroendocrine tumours and carcinomas

Introduction: Neuroendocrine neoplasms (NENs) consist of neuroendocrine tumours and neuroendocrine carcinomas, which are rare malignancies found in various anatomical sites, including the gastrointestinal tract, pancreatic islets, lungs, and adrenal glands. Poorly differentiated NECs are classified as high-grade carcinomas that bear resemblance to small-cell lung cancer; however, these patients experience a high risk of relapse and demonstrate a limited response to additional systemic therapies. Adrenocortical carcinoma (ACC) is another rare cancer and currently, no targeted therapies have demonstrated significant effectiveness for this condition. Preclinical investigations have indicated that Delta-like non-canonical notch ligand 1 (DLK1) is expressed in various neuroendocrine neoplasms, including ACC, SCLC, neuroblastoma, pheochromocytoma, and paraganglioma.

#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).
