Abstract:
Objective
To investigate the characters of resting energy expenditure(REE)of perioperative male gastric cancer patients.
Methods
REE was measured by indirect calorimetry and body composition was measured by dual-energy X-ray absorptiometry(DEXA)in 39 male gastric cancer patients，patients were evaluated by mini nutritional assessment(MNA).
Results
REE of gastric cancer patients was lower than the Basal Energy Expenditure(BEE) estimated on Harris-Benedict Equation, REE was positively correlated with lean body mass(LBM)（r=0.635, P＜0.01）. There were significant difference in REE measured before surgery and LBM among patients with different nutritional status, while no difference was found in REE/LBM. REE measured before surgery was lower than that measured after surgery, while respiratory quotient measured after surgery was lower than that measured before surgery.
Conclusion
Male gastric cancer patients show significant reduction in REE measured before surgery,and the reduction is positively correlated with the loss of LBM.More nutritional substrate in appropriate proportion may be supplied after surgery.
