Objective: The objective of our study was to evaluate the detection rate of prostate cancer by digital rectal examination (DRE) and serum prostate-specific antigen (PSA) levels followed by standard 12-core transrectal ultrasound (TRUS)-guided prostate biopsy. Materials and Methods: After screening of patients presenting with lower urinary tract symptoms (LUTS) using DRE and serum PSA level, we enrolled patients for TRUS-guided 12-core prostate biopsy. Indications included PSA level ≥4 ng/ml and/or suspicious DRE findings. A retrospective analysis was done to find out the correlation between suspicious rectal examination and various serum PSA levels in detection of cancer prostate. Results: A total of 847 patients were screened for cancer prostate during our study period (May 2012–February 2020). Among them, 823 patients who underwent prostate biopsy were analyzed. Prostate cancer was detected in 330 cases (40.09%). Mean age of patient (years) with and without prostate cancer was 66.25 ± 9.45 and 64.3 ± 8.96 years, respectively. Median value of serum PSA in patients positive for cancer was 33 ± 260 ng/ml compared to patients without cancer, who had a median value of 9 ± 64 ng/ml (P-value of <0.0001). The detection rate of cancer based on suspicious DRE findings irrespective of PSA was 52.18% (251/481), compared to 45.46% (311/684) using a PSA cut-off of ≥4.0 ng/ml alone. Among 330 patients with positive biopsy, 19 (5.75%) had a PSA level <4 ng/ml and they were identified based on suspicious DRE alone. Conclusion: Suspicious DRE was significantly associated with detection of prostate cancer across all PSA levels. Patients with PSA <4 can harbor prostate malignancy and such cases can be detected by use of DRE in screening of all patients with LUTS.
