The sufficiency of 6 core sextant prostate biopsy in patients with prostate specific antigen (PSA) values over 20 ng/mL

Abstract

Objective: In this study, we aimed to investigate sufficiency of 6 core prostate biopsy in patients with PSA levels elevated above 20 ng/mL. Materials and methods: The medical record of the patients who received prostate biopsy at our institution between August 2011 to August 2016 who had serum total PSA values above 20 ng/mL, were reviewed retrospectively. In this study, we included 40 patients who received 6 core prostate biopsy and 40 patients who received 12 core prostate biopsy. A total number of 80 patients were enrolled in this study. Patients were divided into two groups, a 6 core biopsy group and a 12 core biopsy group. These groups are compared according to age, total PSA, prostate volume and final pathological diagnosis.Results: Based on final pathological diagnosis, 2 patients (5%) had benign pathology and 38 patients (95%) had PCa in both group 1 and 2. The cancer detection rate in both groups was 95%. Although there were higher values of mean age, mean total PSA, and mean prostate volume in group 1, there was no statistically significantly difference at this variables in both groups. Conclusion: Although taking 6 core biopsies is not recently recommended, we proved that 6 core biopsy is adequate for patients with PSA values above 20 ng/mL.
