Advanced gastric cancer achieving major pathologic regression after chemoimmunotherapy combined with hypofractionated radiotherapy: A case report

Figure 1 Enhanced computed tomography images prior to and after combined treatment. A: Enhanced computed tomography (CT) before any treatment showed a lesion in the gastric wall; B: Enhanced CT after combined treatment revealed that the lesion was apparently decreased in size.

Figure 2 Fluorodeoxyglucose positron emission tomography/computed tomography images prior to and after combined treatment. A: Fluorodeoxyglucose positron emission tomography/computed tomography (FDG PET/CT) prior to any treatment showed a large gastric mass with hypermetabolism, and the lesion was clearly decreased in size and metabolism after combined treatment; B: FDG PET/CT prior to any treatment showed hypermetabolism in the left supraclavicular area, and the lesion was clearly decreased in size and metabolism after combined treatment; C: FDG PET/CT prior to any treatment showed hypermetabolism in the left acetabular area, and the lesion was clearly decreased in size and metabolism after combined treatment.
