“…There was no statistical difference in cancer detectability between the TP 14-core biopsy (86%; 243/783) and the TR 12-core biopsy (82%; 231/783) (P = 0.51). As we reported in the preliminary studies [14,15], cancer detection rates of the TP 14-core biopsy and the TR 12-core biopsy were significantly lower than that of the 3D26 biopsy (P = 0.032 and P = 0.005, respectively). Among the 283 cancers, 40 (14%) cancers had positive cores solely in the TR 12 sampling sites (TP-TR + cancers), 52 (19%) solely in the TP 14 sampling sites (TP + TR-cancers) and the remaining 191 (67%) in both TP and TR sites (TP + TR + cancers).…”

“…14,15 In the TP 14-core biopsy, 12 cores were taken from the peripheral zone (A1, A2, P1, P2, AL and PL sites) and 2 from the transition zone (TZ) as reported elsewhere. 7 The TR 12-core biopsy is composed of the conventional parasagittal sextant 6-core (pa, pm and pb sites) biopsy 16 and far-lateral sextant 6-core (la, lm and lb sites) biopsy as described previously.…”

“…7 The TR 12-core biopsy is composed of the conventional parasagittal sextant 6-core (pa, pm and pb sites) biopsy 16 and far-lateral sextant 6-core (la, lm and lb sites) biopsy as described previously. 1,14,15 The biopsy was performed using an 18-gauge biopsy needle driven by an automatic Magnum Biopsy gun (C R Bard , Inc., Covington, GA) under local, spinal or general anesthesia in 3 (0.4%), 541 (69%), and 239 (31%) men, respectively. With the patient in the lithotomy position, the prostate gland was imaged with an ultrasound machine (ALOKA SSD-2000, Aloka, Tokyo, Japan) equipped with both a biplanar 5/7.5 MHz transrectal probe (ALOKA UST-672) and an end-fire 5 MHz transrectal probe (ALOKA UST-670P-5).…”

“…We have demonstrated that, as far as the cancer detection rate is concerned , the three-dimensional combination of TP and TR approaches outperforms the single TP or TR approach at a given number of biopsy cores either in the initial 14 or in the repeated biopsy setting. 15 These results suggest that it might be better to take both the TP and the TR approaches into consideration in the exploration of the optimal biopsy protocol.…”

Aim:To establish whether extended transrectal (TR) and extended transperineal (TP) biopsies are equivalent in detecting prostate cancer. Methods: Due to an elevated prostate-specific antigen (PSA) greater than 2.5 ng/mL or abnormal digital rectal examination findings, 783 men underwent a transrectal ultrasound-guided three-dimensional 26-core biopsy, a combination of TR 12-core and TP 14-core biopsies. Using recursive partitioning, the best combination of sampling sites that gave the highest cancer detection rate at a given number of biopsy cores was selected either with a TR or a TP approach. The cancer detection rate and characteristics of detected cancers were compared between the TP 14-core and the TR 12-core biopsies and between selected subset biopsy schemes. Results: Prostate cancer was detected in 283 of the 783 men (36%). There was no statistical difference in cancer detection rate or in the characteristics of detected cancers between TP 14-core and TR 12-core biopsies. As far as the best combination of sampling sites was selected , there was no statistical difference in cancer detection rates or in the characteristics of detected cancers between the TP and the TR subset biopsy schemes up to 12 cores. TP and TR biopsies performed equally, regardless of a history of negative biopsy, a digital rectal examination finding, the PSA level or the prostate volume. Conclusions: We demonstrated for the first time that extended TP biopsy is as effective as its TR counterpart in detecting cancer and the characteristics of detected cancers, as far as sampling sites are selected to maximize the cancer detection rate.

“…1,2,[8][9][10] Although transperineal biopsy has several advantages over transrectal biopsy including a better sampling from the apico-anterior peripheral zone, [11][12][13] a lower risk of infection complications and no risk of rectal bleeding, 11 the lack of an established local anesthetic method prevents it from becoming the standard.…”

Abstract:We developed a local anesthetic procedure for three-dimensional 26-core prostate biopsy (3D26PBx), a combination of transperineal 14-core biopsy (TP14PBx) and transrectal 12-core biopsy (TR12PBx). At first, a periapical triangle, confined by the levator ani, the rhabdosphincter and the external anal sphincter muscle, was made visible by transrectal ultrasound. After administration of 1 mL of 1%-lidocaine into the midline perineal skin 1.5 cm above the anus, we inserted a spinal needle toward the periapical triangle for injection of 1.5-2.0 mL of 1%-lidocaine and performed the TP14PBx. After administration of the periprostatic nerve block with 10 mL of 1%-lidocaine, we performed the TR12PBx. The efficacy of the procedure was evaluated prospectively in 45 consecutive men undergoing the 3D26PBx. The 3D26PBx was completed with just local anesthesia in all patients. The pain levels, assessed by an 11-point visual analog scale, were not different between the TP14PBx and the TR12PBx.

Three-dimensional combination of transrectal and transperineal biopsies for efficient detection of stage T1c prostate cancer

Abstract: We propose a three-dimensional 14-core and a three-dimensional 8-core biopsy as efficient first-time biopsy schemes to detect stage T1c and T2 prostate cancer, respectively.
