Associations of volumetric whole-body F-FDG PET/CT parameters with the CA 19-9 level and haemogram parameters in pancreatic adenocarcinoma.

Objective: The present study compared metabolic and volumetric fluorine-18-fluorodeoxyglucose (F-FDG) positron emission tomography/computed tomography (PET/CT) parameters [metabolic tumour volume (MTV), total lesion glycolysis (TLG), and maximum standardized uptake value (SUVmax)] with carbohydrate antigen (CA) 19-9 tumour marker levels and haemogram parameters [(neutrophil-lymphocyte ratio, mean platelet volume (MPV), and platelet-lymphocyte ratio] as prognostic and diagnostic markers of pancreatic cancer.

Material And Methods: A total of 66 patients who underwent F-FDG PET/CT in our nuclear medicine clinic between February 2017 and March 2019, and had a diagnosis of pancreatic adenocarcinoma, were included in this retrospective study. The enrolled patients had not been administered steroids or operated on.
