title: [Relationship of body mass index with cancer detection in prostate biopsy].
abstract: OBJECTIVE
  To investigate the relationship of body mass index with cancer detection on prostate biopsy.
  
  
  METHODS
  A total of 168 patients undergoing a prostate biopsy were divided into obese and non-obese groups by BMI ≥ 25 or < 25. Then the differences of prostate-specific antigen (PSA) level, prostate volume, prostate cancer detection rate and pathology result between two groups.
  
  
  RESULTS
  The obese group had a higher rate of cancer detection than the non-obese group [67.1% (51/76) vs 48.9% (45/92), P < 0.05]. Logistics regression analysis showed that BMI ≥ 25 had a positive correlation with cancer detection on biopsy.
  
  
  CONCLUSIONS
  Body mass index can raise the risk of prostate cancer on biopsy.
