Patterns of radiotracer uptake in patients with resectable lung carcinoids undergoing preoperative functional imaging

#3975

Introduction: There is paucity of real-world data on the use of preoperative functional imaging (PFI) in patients (pts) with lung carcinoids (LC), and the association of radiotracer uptake (RU) with histology/outcomes.

Aim(s): To explore PFI use/associations between RU and disease biology/relapse in LC.

Materials and methods: Our database was queried for pts with resected LC undergoing PFI with 68Gallium-DOTATATE positron emission tomography (68Ga PET), somatostatin-receptor scintigraphy (SRS) and non-somatostatin receptor (SSTR) imaging with 18-fluorodeoxyglucose (18F-FDG) PET. RU for SSTR PFI was defined as low (per radiologist and/or Krenning score (KS) ≤2) or high (per radiologist and/or KS>2). RU for 18F-FDG PET was defined as low (Standardized Uptake Values – SUVmax<5) or high (SUVmax ≥5).
