SUMMARY

During the ENETS Conference, the NETTER-2 trial was again in the spotlight and is shifting [177Lu]Lu-DOTATATE PRRT to the first-line treatment setting of patients with advanced, well-differentiated grade 2 and grade 3 gastroenteropancreatic neuroendocrine tumours (NET). Nuclear medicine treatment for NET is now intensively focusing on alpha-emitting peptide receptor radionuclide therapy (PRRT). Adding immunotherapy to angiogenesis inhibition for NET is again a disappointing story, and all eyes are now set on the CAR T-cell technology to stimulate anti-tumour immune responses. Delta-like ligand 3 is an inhibitory Notch ligand selectively and highly expressed on the cell surface of small cell lung cancer and neuroendocrine carcinoma, and appears to be a promising target for bispecific T-cell engager therapy. In this report, the most important headlines will be discussed, with comments on the clinical relevance of the different studies.
