Figure 1 F-18 fluorodeoxyglucose positron emission tomography/computed tomography images of a gastric cancer patient with diffusely increased F-18 fluorodeoxyglucose uptake of bone marrow. A: Maximum intensity projection; B and C: Coronal and transaxial PET images; D: Transaxial CT image; E: Fused transaxial PET/CT image of a 71-year-old woman with advanced gastric cancer. Focal intensely increased FDG uptake was observed in the primary tumor lesion of stomach with Tmax of 8.36 (arrow). BM of the patient showed increased FDG uptake with BM SUV of 2.36 and BLR of 1.25. The patient underwent total gastrectomy. The cancer recurred 13.4 mo after the treatment and the patient died 18.5 mo after the operation. PET/CT: Positron emission tomography/computed tomography; FDG: F-18 fluorodeoxyglucose; BM: Bone marrow; BLR: BM-to-liver uptake ratio.

Figure 2 F-18 fluorodeoxyglucose positron emission tomography/computed tomography images of a gastric cancer patient with minimally increased F-18 fluorodeoxyglucose uptake of bone marrow. A: Maximum intensity projection; B and C: Coronal and transaxial PET images; D: Transaxial CT image; E: Fused transaxial PET/CT image of a 75-year-old woman with advanced gastric cancer. Focal intensely increased FDG uptake was observed in the primary tumor lesion of stomach with Tmax of 7.57 (arrow). BM SUV and BLR were 1.12 and 0.54, respectively. The patient underwent total gastrectomy. The patient is still alive without cancer recurrence with a follow-up period of 35.5 mo. PET/CT: Positron emission tomography/computed tomography; FDG: F-18 fluorodeoxyglucose; BM: Bone marrow; BLR: BM-to-liver uptake ratio.

Figure 3 Kaplan-Meier survival curves for recurrence-free survival and overall survival. A: Recurrence survival curve according to T stage; B: Overall survival curve according to T stage; C: Recurrence-free survival curve according to BLR; D: Overall survival curve according to BLR. BLR: Bone marrow-to-liver uptake ratio.
