Predictive Value of Transrectal Ultrasound in the Diagnosis of Prostate Cancer
Journal Title: International Journal of Contemporary Medicine surgery and Radiology - Year 2018, Vol 3, Issue 3
Abstract
Introduction: Prostate cancer incidence is on the rise worldwide with a significant number of patients being diagnosed with advanced disease. Transrectal ultrasound (TRUS) is increasingly becoming important in the routine evaluation of patients with suspected prostate cancer because of improvements in its technology. The role of TRUS in the detection of suspicious lesions aside from its use in guiding prostate biopsies, has been brought to question by some studies. Thus study was done to correlate TRUS with histopathology of biopsy specimens so as to determine how accurate it is in diagnosing prostate cancer. Material and Methods: Adult male patients in whom digital rectal examination (DRE) findings indicated prostate biopsy underwent TRUS and subsequently had digitally-guided trucut sextant prostate biopsy. TRUS findings were then correlated with histopathology results. Data analysis was conducted using Statistical Package for Social Sciences (SPSS) version 16 and tests of correlation at 95% confidence limit, and p-value of ≤ 0.05 were conducted. Results: Forty five (45) adult male patients with mean age of 68.1 years and modal age group of 61 – 70 year were studied. The mean prostate volume was 88.5±70.0 cm3 . Over 71% of patients had prostate glands with mixed echogenic features distantly followed by isoechoic features (15.6%) (p > 0.01). Nearly 80% of the 32 patients who had mixed echogenic lesions had a histology of prostate cancer while all the patients with hyperechoic lesions had a benign histology. Conclusion: The cancer detection rate of TRUS was found to be 73.3% in this study. TRUS, though not an accurate test is still relevant in the diagnosis of prostate cancer.
