#4609 External validation of Rachel score: A prognostic tool for lung neuroendocrine tumours

Introduction: Lung NETs are a heterogeneous group of tumours with variegated clinical presentation and course. The histological subtype (TC vs AC) and TNM stage are established prognostic factors. In a previous work by our group, we developed a prognostic model named Rachel score, with a satisfactory ability to predict OS and PFS in this population.

#4462 Clustering of gastroenteropancreatic neuroendocrine neoplasms (GEP-NEN) using machine learning (ML) and comparison with tumour, node, metastasis (TNM) staging: A population-based study using surveillance, epidemiology, and end results (SEER)

Introduction: TNM 8 is the staging system for GEP-NEN, guiding prognosis and treatment. However, it does not include important prognostic factors such as age, sex, race, and morphology.

#4050 PET/CT imaging of the somatostatin receptor with [18F]AlF-NOTA-octreotide PET/CT: Analysis of impact on tumor staging and therapeutic management

Introduction: [18F]AlF-NOTA-octreotide ([18F]AlF-OC) is a promising alternative for [68Ga]Ga-DOTA-somatostatin analogues (SSAs) in PET imaging of the somatostatin receptor (SST).

#4012 14 years of the Czech Neuroendocrine Tumors Registry

Introduction: Czech Cooperative Group for NETs was established on 22 April 2008. It continues with the practices of the Czech Carcinoid Group founded 1998. The Czech Neuroendocrine Registry was started in 2009 as a platform that should facilitate the data based on communication among various specialists treating NETs.
