Retrospective analysis of somatostatin receptors expression in cohort of thoracic neuroendocrine neoplasms with immunohistochemistry method or PET/CT Ga68 DOTA-TATE
Introduction:
Somatostatin receptors (SSTRs) expression in cohort of thoracic neuroendocrine neoplasms (NENs) is still not fully described. We attempted to evaluate the SSTR expression by IHC and PET/CT with Ga68 DOTA-TATE, as well as the sensitivity of both methods.

18F-FDG PET/CT-avid discordant volume as a biomarker in patients with gastroenteropancreatic neuroendocrine neoplasms – A multicentre study
Introduction:
Dual 18F-FDG and 68Ga-DOTATATE PET/CT is emerging as a powerful technique to predict tumor biology. Whilst the presence of discordant disease (FDG avid/DOTA non-avid) predicts poor prognosis, it remains unknown whether the volume of discordant disease is also a significant predictor.

Analysis of Discordance between Biopsy Grade and Surgical Pathology Grade in Resected PanNEN Patients
Introduction:
In PanNEN cases, treatment strategies are decided by tumor localization, volume and grade. In unresectable or metastatic cases, tumor grade is determined by biopsy specimen obtained from EUS-FNA and diagnostic accuracy of biopsy according to WHO classification 2017 is important for decision making of treatment.
