#2985 Peptide Receptor Radionuclide Therapy (PRRT) Outcome Prediction in Neuroendocrine Tumors (NET): Could Radiomic Features Analysis of 68Ga-DOTATOC PET/CT Have a Roll?

Introduction: The PRRT is an effective treatment for NET, but the selection of a good candidate is a very important step.

#2939 Prognostic Evaluation for Gastroenteropancreatic NEC: AJCC or ENETS Staging Classification or Others?

Introduction: For poorly-differentiated gastroenteropancreatic neuroendocrine carcinoma (GEP-NEC), American Joint Committee on Cancer (AJCC) recommends to use a classification different from that for well-differentiated neuroendocrine tumor. However, this is not adopted by European Neuroendocrine Tumor Society (ENETS) staging classification.

#2920 Mutation Spectrums Analysis of Colorectal Adenocarcinoma and Neuroendocrine Neoplasm Based on Same Genetic Background to Reveal Tumorigenesis

Introduction: The tumorigenesis of neuroendocrine neoplasm (NEN) are still ambiguous. The therapies of NENs in colon or rectum refer to adenocarcinomas (AC) when tumor metastasis, but the response was unsatisfactory which inspired us to explore the mutation difference.

#2823 Peptide Receptor Radionuclide Therapy in Rectal Neuroendocrine Tumours

Introduction: Neuroendocrine tumours (NETs) arising from the rectum are more common in the Asian population. Current treatment options include somatostatin analogues, chemotherapy, and more recently, peptide-receptor radionuclide therapy (PRRT). Peptide receptor radionuclide therapy (PRRT) has been shown to be effective in the treatment of advanced gastroenteropancreatic (GEP) tumours with minimal adverse effects. Studies have also suggested that rectal NETs show good response to PRRT, better than GEP NETs.
