Body composition between obstructive and non-obstructive bladder cancer: A retrospective study

Background: Body composition measurement during cancer follow-up would increase its role in improving nutritional status. Using a CT scan for nutritional evaluation with scheduled cancer screening or follow-up would add other useful information to help the physician gain a better understanding of the patient’s nutritional status, especially in adipose tissue. Objective: To evaluate the correlation of measured adipose tissue and skeletal muscle between obstructive and non-obstructive uropathy in bladder cancer on a CT scan. Background: Body composition measurement during cancer follow-up would increase its role in improving the nutritional status.

Objective: To compare the measured adipose tissue and the skeletal muscle between obstructive and non-obstructive uropathy in bladder cancer on a CT scan. Materials and Methods: A total of 69 patients, who underwent a CT scan of the abdomen including the pelvis before surgery and/or chemotherapy between January 2013 and December 2022, were enrolled. Analyses of the volume of visceral adipose tissue (VAT), subcutaneous adipose tissue (SAT), and skeletal muscle tissue (SMT) calculated based on CT images were performed. Results: There was significantly lower VAT (p = 0.012) in the obstructive group than in the non-obstructive group. SAT, SMT, age, weight, height, BMI, and tumor size were not significantly different between both groups. Conclusion: In patients with bladder cancer, those with obstructive uropathy showed lower VAT than non-obstructive uropathy.
