INTRODUCTION: The aim of this study is to verify the predictive role of transrectal ultrasound (TRUS) of prostatic fossa, digital rectal examination (DRE), prostate specific antigen (PSA) and pathological stage after radical prostectomy in the detection of a prostate tumor recurrence at the level of the vesico-urethral anastomosis by means of multiple TRUS biopsies (6-8 cores).MATERIAL AND METHODS: From October 1997, following a radical prostatectomy, 119 consecutive patients (median age: 67.9 years) with a PSA>or=0.2 ng/ml (median PSA: 0.9 ng/ml) underwent DRE and TRUS examinations with a 5.0-7.5 MHz variable frequency end-fire probe (Hitachi Medical System) and an EUB-525 machine. All patients received six TRUS-guided biopsies of the vesico-urethral anastomosis, and 1-2 additional biopsies directed to hypo-echoic or suspicious areas, if detected by TRUS.RESULTS: Biopsies revealed recurrent carcinoma in 50% of patients (60/119). TRUS proved more sensitive than DRE (75% vs. 50%; p=0.01) and, conversely, DRE proved more specific than a TRUS (85% vs. 66%; p=0.03). Cancer was detected in 45% of the 34 patients with a PSAor=2.0 ng/ml (24 patients), TRUS was able to detect every biopsy-proven local recurrence lesion (sensitivity: 100%). Conversely, all patients with a PSA>or=2.0 ng/ml and a negative TRUS had a negative biopsy (negative predictive value: 100%). In a multi-variable logistical analysis, the most predictive parameters determining a positive biopsy rate among those values studied (PSA, DRE, TRUS, positive surgical margins, pathological stage and time to PSA elevation) were TRUS and DRE findings (p=0.003, with an odds ratio of 4.6 and p=0.02, with an odds ratio of 4.1, respectively).CONCLUSION: TRUS and TRUS biopsies utilizing 6-8 cores are efficient tools in the detection of local recurrence after a radical prostatectomy, even with a PSAor=2.0 ng/ml and a negative TRUS, a biopsy of the vesico-urethral anastomosis could be avoided since the negative predictive value is 100%. Cancer recurrence detection seems to be predicted by TRUS and DRE findings, but not by PSA levels, pathological stage, status of the surgical margins or time to PSA elevation.  相似文献

The objective of this paper is to validate prostate specific antigen (PSA) density (PSAD) routine use to enhance PSA specificity in men with normal digital rectal examination and intermediate PSA values. It is a retrospective study of 235 men from a prostate cancer (PCa) screening program. All of them presented PSA values between 4 and 10 ng/ml, normal digital rectal examination, and a transrectal ultrasound (TRUS) guided biopsy available (PSA>/=4 ng/ml as the sole criterion for biopsy). Multivariate analysis failed to demonstrate higher PSAD values in men with PCa. PSAD cutoff points higher than 0.07 ng/ml per cc were considered as unacceptable, with less than 95% sensitivity. When a cutoff point of 0.15 was considered, as many as 30.6% of the cancers were missed. In conclusion we cannot recommend the use of this parameter for the above mentioned purpose.Prostate Cancer and Prostatic Diseases (2001) 4, 146-149.  相似文献

Study Type – Diagnostic (case series)
Level of Evidence 4

OBJECTIVES

To assess the prostate cancer detection rate and predictive factors for prostate cancer after transrectal ultrasonography (TRUS)‐guided transperineal saturation re‐biopsies of the prostate, using a 24‐core scheme.

PATIENTS AND METHODS

We evaluated 143 consecutive patients undergoing TRUS‐guided transperineal saturation re‐biopsy of the prostate using a 24‐core scheme. The inclusion criteria were a previous negative biopsy and a prostate‐specific antigen (PSA) level of ≥10.0 ng/mL, or of 4.0–10.0 ng/mL with a free/total ratio of <20% or an abnormal digital rectal examination or previous high‐grade prostatic intraepithelial neoplasia (HGPIN) or atypical small acinar proliferation (ASAP).

RESULTS

The mean (sd ) age of the patients was 66.5 (6.1) years and the median (interquartile range) PSA level was 9.0 (6.1–12.8) ng/mL. The number of previous biopsies was one in 59% of patients, two in 26% and three or more in 15%. We detected prostate cancer in 26%, ASAP in 5.6% and HGPIN in 2.1%. The cancer detection rate was 47%, 25.5% and 14% for prostate volumes of <40, 40–60 and ≥60 mL, respectively (P = 0.002). On a multivariate analysis the total prostate volume (40–60 vs <40 mL, hazard ratio 5.683; >60 vs <40 mL, hazard ratio 6.965; P = 0.01) was the only significant predictor of prostate cancer at saturation biopsy.

CONCLUSIONS

TRUS‐guided transperineal saturation re‐biopsy of the prostate using a 24‐core scheme resulted in a high cancer detection rate also in patients who had had two or more previous biopsies. The total prostate volume was the only predictor of prostate cancer.  相似文献

Study Type – Diagnostic (exploratory cohort) Level of Evidence 2b What's known on the subject? and What does the study add? Template assisted transperineal biopsy of the prostate has become increasingly popular over the past decade. Several studies have demonstrated that transperineal prostate biopsy (TPB) is associated with an increased rate of cancer detection, increased histological concordance with final prostatectomy samples and an increase in anterior and apical prostate cancers than standard TRUS biopsy. However, interpretation of the literature is difficult due to considerable variation between studies in terms of technique and equipment. We examined a small cohort (n= 40) of patients using a standardized 36 core template assisted TPB technique. We show that utilising this technique is associated with high cancer (68%) detection rate in patients with two previous negative TRUS biopsies. Of patients were found to have anterior gland tumours which would not have been detected by standard TRUS guided biopsy.

OBJECTIVE

? To determine the efficacy and safety of a standardized 36 core template‐assisted transperineal biopsy technique for detecting prostate cancer in patients with previously negative transrectal ultrasonography‐guided prostate biopsies and elevated prostate‐specific antigen (PSA) levels.

PATIENTS AND METHODS

? Between April 2008 to September 2010, a total of 40 patients with a mean (range) age of 63 (49–73) years, a mean (range) elevated PSA level of 21.9 (4.7–87) ng/mL and two previous sets of negative TRUS‐guided prostate biopsies underwent standardized 36 core template‐assisted transperineal prostate biopsies under general anaesthetic as a day case procedure. ? The cancer detection rate and complications for all cases were evaluated.

RESULTS

? In total, 27 of 40 (68%) patients were found to have adenocarcinoma of the prostate, two patients (5.0%) had atypical small acinar proliferation, one had high‐grade prostatic intraepithelial neoplasia (2.5%), four (10%) had chronic active inflammation and six (15%) had benign histology. ? Gleason scores were in the range 6–9, with a median Gleason score of 7. ? There were no cases of urosepsis, urinary tract infections or haematuria. A single patient experienced acute urinary retention, with a subsequent succesful trial without a catheter, and haematospermia was common, although minor.

CONCLUSIONS

? Our standardized 36 core template‐assisted transperineal prostate biopsy technique is safe and associated with a high detection rate of prostate cancer. ? This technique should be considered in patients with elevated PSA levels and previously negative TRUS‐guided prostate biopsies.  相似文献

BACKGROUND: There are currently no prostate cancer screening guidelines specific to the end-stage renal disease (ESRD) population. With this in mind, we evaluated the clinical usefulness of digital rectal examination (DRE), serum total prostate-specific antigen (PSA), prostate-specific antigen density (PSAD) and transrectal ultrasound (TRUS) in predicting prostate cancer in men with ESRD. METHODS: Fifty male ESRD patients age 40 years and older with no prior history of prostate cancer were enrolled in the study. All patients underwent PSA measurement and a DRE followed by a TRUS. PSAD was calculated as the total PSA divided by the prostate volume. Ultrasound-guided prostate biopsies were performed on any patient with 1 or more of the following abnormal findings: a nodule detected on DRE; an abnormal TRUS; PSA > 4.0 ng/ml, or a PSAD > 0.15 ng/ml/cm3. RESULTS: Abnormal findings were detected in 19 patients. Two (4%) had an abnormal DRE, 3 (6%) had PSA > 4.0 ng/ml, 3 (6%) had PSAD > 0.15 ng/ml/cm3 and 16 (32%) had abnormal findings on TRUS. Three patients had 2 abnormal findings and 1 had 3. Of the 15 prostate biopsies performed, 4 (27%) revealed prostate cancer and 3 (20%) high-grade prostatic intraepithelial neoplasm (HGPIN) comprising 8% and 6%, respectively, of the studied population. Of the 4 patients diagnosed with prostate cancer, none had abnormal DRE, 2 (50%) had PSA > 4.0 ng/ml (sensitivity = 66.7% and PPV = 50% (p = 0.236)), 3 (75%) had PSAD > 0.15 ng/ml/cm3 (sensitivity = 100% and PPV = 75% (p < 0.018)), and 3 (75%) had abnormal findings on TRUS (sensitivity = 30% and PPV = 75% (p = 1.000)). CONCLUSION: Routine screening with PSA and DRE does not seem sensitive enough to predict the presence of the disease. Although TRUS detected abnormalities in 16 patients (32%), sensitivity was very low (30%). In our patients, PSAD increased the sensitivity and positive predictive value (PPV) of detecting prostate cancers compared to PSA alone.  相似文献
