Peripheral Blood Biomarkers of Systemic Inflammation May Be Prognostic in Metastatic Gastroenteropancreatic Neuroendocrine Tumour (GEPNET) Patients Following 177Lu-DOTATATE (LuTate) Abstract #1893

Introduction: LuTate is a treatment for well-differentiated NETs with adequate somatostatin receptor expression. Prognostic biomarkers in this population are lacking. Neutrophil-to-lymphocyte ratio (NLR) is prognostic in the majority of solid tumours but is reported to have less value in indolent well-differentiated NETs.
Aim(s): To investigate the prognostic impact of NLR, lymphocyte-to-monocyte ratio (LMR) and platelet-to-lymphocyte ratio (PLR) in patients (pts) with advanced GEPNET.
Materials and methods: We identified pts with well-differentiated GEPNETs who received LuTate for progressive disease or refractory hormonal syndrome. The relationship between baseline biomarkers, histological grade and progression free survival (PFS)/overall survival (OS) was analysed using multivariate regression models. Progression was defined as new or enlarging lesions on 68Ga-DOTATATE PET/CT.

#1879 A Hybrid Clinical Molecular Nomogram Accurately Predicts Survival in PRRT Treated GEP-NETs
Introduction: Clinical assessment has limited prognostic ability. Mathematical tools –nomograms- that incorporate multiple parameters are more effective. Novel transcriptomic data has added value in defining NET biology in tissue and blood. A blood multigene expression analysis test is effective as a molecular prognostic marker for PFS.

#1787 Towards Personalizing PRRT with [177Lu]-Dotatate to Minimise Renal Toxicity in Neuroendocrine Tumour Patients
Introduction: The kidney is a dose-limiting organ in [177Lu]-Dotatate PRRT (Lutate) and thus renal function is an important prescribing consideration for NET patients. The effect of baseline renal function on kidney absorbed dose is unclear.

Introduction: Bulky disease from NET is an adverse prognostic factor for response to 177Lu-DOTA-octreotate (LuTate) PRCRT. 90Y-DOTA-octreotate (YTate) has more penetrating particulate emissions.
