#4251 Upfront Oxaliplatin–Fluoropyrimidine chemotherapy and Somatostatin Analogues (SSA) in advanced well-differentiated G2/G3 gastro-entero-pancreatic neuroendocrine tumors (GEP-NETs)

Introduction: Gastroenteropancreatic neuroendocrine tumors (GEP-NETs) are frequently diagnosed at advanced stage. For well-differentiated somatostatin receptor-positive (SSTR +) NETs, somatostatin analogues (SSAs) are the preferred first-line therapy. However, in patients (pts) with G2/G3 and a high tumor burden, SSA alone might not be enough.

#4220 Risk of bowel ischemia in patients with mesenteric neuroendocrine tumors after treatment with 177Lutetium-DOTATATE

Introduction: 177Lutetium (Lu)-DOTATATE is an effective treatment for metastatic gastroenteropancreatic neuroendocrine tumors (GEP-NETs). However, radiation can cause transient inflammation/swelling of tumors which can result in toxicity. Treatment-related small bowel obstruction associated with mesenteric or peritoneal disease has been described.

#4192 Real-world efficacy and safety of re-treatment with [177Lu] Lu-DOTA-TATE in patients with neuroendocrine tumors (NETs)

Introduction: The established efficacy and safety of [177Lu]-DOTA-TATE in metastatic gastroenteropancreatic neuroendocrine tumors (GEP-NETs) and bronchial NETs (G1, G2) have paved the way for exploration into re-treatment ([177Lu] RR-PRRT) safety and efficacy, an area with limited available data.

#4186 The effect of the Covid-19 pandemic on the body composition of patients with gastroenteropancreatic neuroendocrine tumors using a somatostatin analogue

Introduction: The Covid-19 pandemic and its restrictions had a negative impact on the general population. Due to lockdowns, food intake increased and exercise decreased. This led to weight gain and changes in body composition. Hospitals reviewed patients (pts) remotely. The effect of the Covid-19 pandemic has not been described in pts with gastroenteropancreatic neuroendocrine tumors (GEP-NETs) treated with somatostatin analogue (SSA).
