Indications of prostate biopsy are high serum prostate specific antigen (PSA) value and or abnormal digital rectal examination (DRE) findings. Although serum PSA value of 4 ng/ml is the most commonly used threshold for recommending prostate biopsy, significant proportion of men harbor prostate cancer even when their serum PSA values are less than 4.0 ng/ml. Therefore present study was designed to determine the performance status of serum PSA in lower cut-off values. This hospital based prospective study was conducted in the Department of Urology of Bangabandhu Sheikh Mujib Medical University (BSMMU) and Comfort Nursing Home Pvt. Ltd, Dhaka from July 2009 to October 2010.
