#4589 Clinical efficacy of RLT to assess OS and PFS using 177Lu DOTATATE, 90Y DOTATATE, and a mixture of both in patients with advanced, unresectable, progressive rectal NET – A retrospective analysis

Introduction: Retrospective, single-arm, open-label, case series study evaluating the efficacy of different types of radioligand therapy (RLT): 177Lu, 90Y DOTATATE, or mix of both used in advanced, unresectable progressive rectal NETG1/G2.

#4541 Prognosis analysis of metastatic rectal neuroendocrine tumour: Liver-directed trans arterial embolisation may play a pivotal role

Introduction: Rectal neuroendocrine tumour (rNET) is prone to metastasis, and distant metastasis is associated with worse prognosis. However, factors influencing the prognosis of metastatic rNET and the recommended treatments remain controversial.

#4350 Cytoendoscopy for determining the depth of invasion and metastasis of rectal neuroendocrine tumours

Introduction: Rectal neuroendocrine tumours (rNETs) are relatively common submucosal tumours, but even low-grade rNETs can metastasise. The significance of endocytology (EC) in the clinical evaluation of rNETs has not been reported.

#4322 Clinical outcomes of patients with rectal neuroendocrine tumours smaller than 10mm after endoscopic resection

Introduction: Rectal neuroendocrine tumours (r-NETs) generally have a good prognosis, but up to 20% may be misdiagnosed during endoscopy, risking inadequate treatment. Prognosis factors include tumour size, grading, staging, and lymphovascular invasion, with guidelines recommending endoscopic resection for small, low-grade lesions.
