Integrated analysis of glucose, lipid, and urea metabolism in patients with bladder cancer. Impact of tumor stage.

Objective: The aim of the study was to characterize the metabolic changes in non-weight-losing patients with cancer of the bladder and to investigate the effect of tumor stage. The kinetics of glucose, glycerol, and urea metabolism were assessed in 22 weight-stable patients with non-metastatic bladder cancer (tumor stage p T2, n = 14) and 10 patients with benign uterine myoma (controls).

Methods: The kinetics of glucose, glycerol, and urea metabolism were assessed by [6,6-(2)H(2)]glucose, [1,1,2,3,3-(2)H(5)]glycerol, and [(15)N(2)]urea.
