The impact of baseline 18 F-FDG PET-CT on the management and outcome of patients with gastric cancer: a systematic review.

Studies indicated that FDG PET-CT added benefit in gastric cancer staging by detecting more distant metastases, but these studies were generally of low quality and at high risk of bias. Intestinal subtype of gastric adenocarcinoma tended to be more FDG-avid and therefore more distant metastases were subsequently detected.
