Summary

As the number of obesity continues to increase, surgical oncologist pay more attention to the effect of obesity on surgical outcomes and survival of digestive systemin cancers. Body mass index(BMI) is one of the most widely used measurements of obesity. Abdominal fat area (AFA) calculated by computed tomography is popular because of its validity of fat distribution. There is still no consensus which of BMI and AFA could be the more effective measurement and more accurate to evaluate effect of obesity on surgical outcomes and survival. Gastric cancer is one of the most common digestive system cancers, and gastrectomy is the primary therapeutic options.It is important to compare the different measurements(BMI or AFA) to assess obesity and effect on surgical outcome and survival for gastric cancer patients.

Conditions

Interventions

DEVICE

AFA group (successive patients)

The abdominal fat area at the umbilical level was measured using a CT scanner(sango Mount Monitor Wireless Panel; Siemens , Munich, Germany) while the examinee was in a supine position and estimated using a Volume software (fat Pointer; Siemens , Munich, Germany). The imaging conditions were 120 kilovolt and 50 milliampere, using a 5-mm-thick slice.The areas covered by visceral fat software calculated from pixels with densities ranging from-190 to -30 hounsfield unit . No contrast agent is needed.

OTHER

BMI group (successive patients)

The formula for BMI is weight in kilograms divided by height in meters squared (kg/m2). the normal range is usually considered to be 18.5 to 24.9, with less than 18.5 considered underweight, more than 25.0 considered overweight and above 30.0 obese.
