Can Cancer Detection Rate Increase When Transrectal Biopsies Taken From The Laterally?

Abstract

Background: Prostate biopsies of the lateral peripheral zone biopsies from the general opinion is that the more cancer is seen. In our study, the incidence of cancer in the lateral peripheral zone biopsies were investigated.

Materials and Methods: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. Results:The average age of the patients was 67.2 ± 10.3 . Total PSA value in patients  was found 13.7 ng / ml. Prostate cancer was detected 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 the rate of 47.7% (10 patients) in patients. Prostate cancer was  more commonly detected in LPZ (p<0,05).

Conclusıons: Prostate biopsies of the LPZ biopsies more commonly cancer is seen. We believe will increase the capture rate for prostate cancer if a sufficient number of biopsies taken from the LPZ.
