“…Indeed, the apex anterior location is important. In Japan, it was previously reported that most common tumor location was in the apex [17]. In our study, the tumor location was almost equally distributed between apex-anterior and posterior, but the PRM frequency was higher in the anterior.…”

“…The AFMS does not play a role as a landmark or a margin any longer. It is well recognized that carcinoma frequently arises from the anterior apical prostate (Takashima et al 2002). One of the serious problems in radical prostatectomy is the diversity of outcomes, most of which are attributable to surgeon and/or hospital volumes and to pathological diagnosis.…”

“…Takashima et al (13) analyzed the distribution of prostate cancer using computer prostate models constructed from pathologic slides of radical prostatectomy specimens, and found that the distribution rates of prostate cancer in the mid-prostate level and anterior apex were 85.5% and 82.3%, respectively, and most nonpalpable prostate cancer was located in the mid-prostate level and anterior apex. In this study, prostate cancer was located only in the anterior apex in 3 (3.2%) of the 95 patients who were diagnosed with prostate cancer by 6-core biopsy and 12 (25%) of the 48 patients who were diagnosed by 12-core biopsy; 12-core biopsy significantly increased the cancer detection rate.…”

Objective: We compared the safety and efficacy of the 12-core biopsy with those of the conventional systematic 6-core biopsy with PSA levels between 4.1 and 20.0 ng/mL. Materials and Methods: This study included 428 patients who underwent a 6-core biopsy and 128 patients who underwent a 12-core biopsy. Biopsies were performed transrectally under ultrasound guidance. The 12-core biopsy scheme involved obtaining 6 far lateral cores. Results: For patients with PSA level between 4.1 and 10.1 ng/mL, 47 of the 265 patients who underwent 6-core biopsy and 32 of the 91 patients who underwent a12-core biopsy were diagnosed with prostate cancer (p = 0.0006). Among the patients with a PSA level between 10.1 and 20.0 ng/mL, 48 of 163 patients who underwent the 6-core biopsy and 16 of 37 patients who underwent the 12-core biopsy were diagnosed with prostate cancer (p = 0.0606). Three of the 95 patients who were diagnosed with prostate cancer through the 6-core biopsy and 12 of the 48 patients who were diagnosed through the 12-core biopsy had cancer located in the anterior apex. The 12-core biopsy increased the diagnostic rate in the apex (p = 0.001). No statistically significant differences were found in incidence of complications. Conclusion: We concluded that the 12-core biopsy is a safe and more effective procedure for increasing the diagnostic rate of prostate cancer than the 6-core biopsy in patients with PSA level between 4.1 and 10.0 ng/mL, and the most useful anatomical area to be added was found to be cores from the anterior apex.
