Diagnostic Performance of Initial Transperineal Template-guided Mapping Biopsy of the Prostate Gland.

Objectives: To evaluate the utility of transperineal template-guided mapping biopsy (TTMB) of the prostate as an initial means of establishing tissue diagnosis.

Materials And Methods: A total of 191 consecutive patients underwent TTMB of the prostate using an anatomic-based technique with sampling of 24 regions. All patients had elevated prostate-specific antigen on routine screening which was followed by a confirmatory prostate-specific antigen and none had undergone previous biopsy of the prostate.

Transperineal template-guided mapping biopsy as a staging procedure to select patients best suited for active surveillance.

Objectives: Patients with clinically insignificant prostate cancer are candidates for active surveillance. However, uncertainty regarding the true extent of disease limits enthusiasm. In this study, we report our initial findings in patients with transrectal ultrasound (TRUS)-detected clinically insignificant prostate cancer undergoing transperineal template-guided mapping biopsy (TTMB) as a staging procedure.

The incidence of transition zone prostate cancer diagnosed by transperineal template-guided mapping biopsy: implications for treatment planning.

Objectives: To report the incidence of transition zone (TZ) cancer in patients undergoing transperineal template-guided mapping biopsy (TTMB) of the prostate gland.

Methods: Five hundred thirty-nine consecutive patients underwent TTMB by means of an anatomic technique with sampling of 24 defined prostate regions. The position of each biopsy core was recorded in 3 dimensions.

Obesity does not correlate with adverse pathologic findings on transperineal template-guided mapping biopsy of the prostate.

Background: Obesity has correlated with adverse pathologic features on prostate biopsy and may predispose to a higher rate of prostate cancer-related death after radical prostatectomy. In this study, we examine the potential relationship between body mass index (BMI) and histopathologic findings on transperineal template-guided mapping biopsy of the prostate (TTMB).

Methods: From January 2005 to January 2008, 244 consecutive patients underwent TTMB using an anatomic-based technique.

Prebiopsy PSA velocity not reliable predictor of prostate cancer diagnosis, Gleason score, tumor location, or cancer volume after TTMB.

Objectives: To evaluate the effect of prostate-specific antigen (PSA) velocity (PSAV) on prostate cancer diagnosis, Gleason score, tumor location, and cancer volume in men undergoing transperineal template-guided mapping biopsy (TTMB). PSAV has been associated with greater Gleason scores and greater prostate cancer-specific mortality.

Methods: From January 2005 through September 2007, 217 patients underwent TTMB.

The morbidity of transperineal template-guided prostate mapping biopsy.

Objective: To evaluate the effect of transperineal template-guided prostate mapping biopsy (TTMB) on urinary, bowel and erectile function.

Patients And Methods: In all, 129 men had TTMB; a median of 56 biopsy cores were obtained per patient. Tamsulosin (0.

Prostate cancer distribution in patients diagnosed by transperineal template-guided saturation biopsy.

Objectives: To determine the prostate cancer incidence, anatomic distribution, Gleason score profile, and tumor burden in patients diagnosed by transperineal template-guided saturation biopsy (TTSB).

Materials And Methods: One hundred and two patients underwent TTSB; all but one patient had undergone at least one prior negative TRUS biopsy. Criteria for inclusion included an elevated PSA and/or the diagnosis of ASAP or high-grade PIN on prior biopsy.
