Table 4. Change in body composition over time in patients with GC (n=43).
| Variables | First CT scan | Second CT scan | P-value |
|---|---|---|---|
| SMA (cm2) | 132.1±30.9 | 123.9±29.6 | 0.001 |
| MA (HU) | 34.0±7.2 | 31.7±6.7 | 0.006 |
| VFA (cm2) | 137.8±96.2 | 113.5±86.4 | 0.001 |
| SFA (cm2) | 136.2±76.3 | 119.6±78.7 | 0.002 |
| SMI (cm2/m2) | 48.2±9.6 | 45.3±9.5 | 0.001 |
| VFI (cm2/m2) | 49.8±34.0 | 41.0±30.1 | 0.001 |
Mean interval (± SD) between CT scans: 86.4±29.0 days.
GC = gastric cancer; CT = computed tomography; SMA = skeletal muscle area; MA = muscle radiation attenuation; HU = Hounsfield unit; VFA = visceral fat area; SFA = subcutaneous fat area; SMI = skeletal muscle index; VFI = visceral fat mass index; SD = standard deviation.
