Can cancer detection rate increase when transrectal biopsies were taken from the laterally?

Acording to general opinion when biopsy is taken from the prostate’s lateral peripheral zone. More cancer is seen. In our study, the incidence of cancer in the lateral peripheral zone biopsies was investigated. In our study, 93 patients were analyzed retrospectively transrectal prostate biopsy. 12 core biopsies were taken from each patient. Medial peripheral zone (MPZ) and lateral peripheral zone (LPZ) biopsies compared the detection of prostate cancer. The average age of the patients was 67.2±10.3. Total PSA value in patients was found as 13.7 ng/mL. Prostate cancer was detected at the rate of 22.5% (21 patients) in 93 patients. 3 patients (14.3%) had prostate cancer in MPZ and 8 patients (38%) had prostate cancer in LPZ. Prostate cancer was detected at MPZ and LPZ at the rate of 47.7% (10 patients) in patients. Prostate cancer was more commonly detected in LPZ (p<0.05). Prostate biopsies of the LPZ biopsies more commonly cancer is seen. We believe it will increase the capture rate for prostate cancer if a sufficient number of biopsies were taken from the LPZ.
