Relationship of body mass index with cancer detection in prostate biopsy

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. Conclusion Body mass index can raise the risk of prostate cancer on biopsy.
