SUMMARY

During the ENETS Conference, the long-awaited results of the phase 3 COMPETE trial were presented, with the comparison of [177Lu]Lu-edotreotide (Peptide Receptor Radionuclide Therapy = PRRT) vs. everolimus in patients with grade 1–2 gastroenteropancreatic neuroendocrine tumours (GEP NET): PRRT outperformed everolimus in terms of objective response rate and also progression-free survival. Also, an update of the phase 2 OCCLURANDOM trial showed the superiority of PRRT vs. sunitinib in a direct comparison between these two treatment modalities. Alpha-PRRT is advancing in the field of NET as a promising treatment option, with the ACTION-1 trial actively recruiting now in Belgium. NET-IMPRESS, a novel methylation-based assay to diagnose and monitor NET patients using liquid biopsies, was rewarded as the most promising basic research project during the conference and will be tested in broader patient populations. Also, the prominent presence of the patient organisations INCA/VZW NET & MEN at ENETS coincides with the rapidly growing field of treatment options in recent years for our patients with NET.

In this report, the most important headlines will be discussed, with comments on the clinical relevance of the different studies.

ESMO NET (Neuroendocrine Tumours) Report 2024: Two breakthrough studies changing the future treatment algorithm of NET

BJMO - volume 19, issue 2, march 2025

SUMMARY

During the ESMO Conference in Barcelona in 2024, two important phase 3 studies in the field of neuro-endocrine tumours (NET) that were presented earlier this year were updated and also published subsequently. The NETTER-2 trial is shifting [177Lu]Lu-DOTATATE Peptide Receptor Radionuclide Therapy (PRRT) to the first-line treatment setting of patients with advanced, well-differentiated grade 2 and grade 3 gastro-enteropancreatic (GEP) NET; the CABINET trial is adding cabozantinib as targeted systemic therapy for previously treated, progressive advanced extrapancreatic and pancreatic NET.

In this report, these two practice-changing NET trials will be discussed in depth, with comments on the clinical relevance and the outstanding questions.

Highlights of the 21st annual European Neuroendocrine Tumour Society (ENETS) Conference

BJMO - 2024, issue 4, june 2024

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.

SUMMARY

The first World NET Forum brought together leading scientists in the neuroendocrine tumour (NET) field to present their cutting-edge research to inspire other scientists and clinicians. This meeting focused mainly on models in NET research, NET tumour biology, as well as therapeutic and diagnostic advances. This article discusses some of the most relevant and promising studies.
