#4657 Should we use the growth modulation index (GMI) in response assessment in G2 neuroendocrine tumours (NETs)?

Introduction: Grade 2 (G2) neuroendocrine tumours (NETs) exhibit diverse behaviours ranging from indolent to aggressive malignancies. Growth Modulation Index (GMI) is the ratio between time to progression (TTP) with a line of therapy (TTPn) and that of the previous line of therapy (TTPn-1). A GMI value equal to or greater than 1,33 has been suggested as an indicator of clinical effectiveness beyond traditional metrics.

#4611 Management strategies and outcomes for type 1 gastric neuroendocrine tumours measuring > 1cm in diameter

Introduction: Although type 1 gastric neuroendocrine tumours (T1-gNETs) are usually considered indolent diseases, the management and the outcome of tumours >1cm remain not well established.

#4596 Gender and metastatic burden as preoperative predictors of disease progression in patients undergoing surgery for pancreatic neuroendocrine tumours with liver metastases

Introduction: Pancreatic neuroendocrine tumour liver metastases (PanNET LM) are traditionally classified into three types based on their distribution. Surgery is generally considered for patients with type I/II LM, while those with type III LM are typically regarded as unresectable. However, type III PanNET LM encompass a wide range of clinical scenarios, some of which may allow surgical resection in selected cases.

#4591 Efficacy of Trabectedin and Olaparib in homologous repair deficient neuroendocrine neoplasms – A subgroup analysis of the TOP-ART / PMO-1603 trial

Introduction: Genomic alterations resulting in homologous recombination deficiency (HRD) occur in a variety of cancers including neuroendocrine neoplasms (NEN). HRD-positive tumours are sensitive to PARP inhibitors such as olaparib. The DNA minor groove binder trabectedin leads to DNA double strand breaks and PARP activation. The combination of Trabectedin + Olaparib (TrO) may therefore have synergistic effects in HRD-positive tumours.
