Prostate Biopsy: Which Technique for Which Results at Lomé University Hospital in 2017?

Abstract

Background: Diagnosis of prostate cancer is certified by histology true prostate biopsies. The aim of our study was to evaluate our prostate biopsy method. Material and Methods: It was a prospective study including patients underwent prostate biopsy. Inclusion criteria were prostate specific antigen (PSA) level up to 4ng/ml and/or abnormal prostate at digital rectal examination. Patients who had risk factors of bleeding have been excluded of the study. The preparation before biopsy included antibioprophylaxy (Ciprofloxacine-Tinidazole) and rectal hypertonic cleaning (Normacol*). Twelve cores have been taken in each prostate by transrectal digital-guided way, using Biopty Gun 18 Gauge. Local anesthesia has been done previously by intrarectal application of 20 ml of gel of Lidocaïne. Two other cores were taken into each abnormal area at rectal examination. The follow-up have been done during twelve weeks. Results: Eighty patients of 65 years of age were included. Nine patients had familial history of prostate cancer. PSA levels ranged from 5 to 6400 ng/ml with a median of 26.77 ng/ml ± 11.2. Complications occurred in 11.25% of patients, principally infectious complications which caused death of one patient by septicemia. The rate of cancer detection was 20%. Prostate abnormality at digital rectal examination and the presence of familial history of prostate cancer were not predictive factors of the presence of cancer on cores. Conclusion: Our prostate biopsy method is limited by the lack of ultrasonographic guidance and is at important risk of infectious complications.
