Biopsy Gleason Score

Introduction: The discrepancy between prostate biopsy and prostatectomy Gleason scores is common. We investigate the predictive value of prostate biopsy features for predicting Gleason score (GS) upgrading in patients with biopsy Gleason scores ≤6 who underwent radical retropubic prostatectomy (RRP). Our aim was to determine predictors of GS upgrading and to offer guidance to clinicians in determining the therapeutic option.Methods: We performed a retrospective study of patients who underwent RRP for clinically localized prostate cancer at 2 major centres between January 2007 and March 2013. All patients with either abnormal digital examination or elevated prostate-specific antigen at screening underwent transrectal ultrasound-guided prostate biopsy. Variables were evaluated among the patients with and without GS upgrading. Our study limitations include its retrospective design, the fact that all subjects were Turkish and the fact that we had a small sample size.Results: In total, 321 men had GS ≤6 on prostate biopsy. Of these, 190 (59.2%) had GS ≤6 concordance and 131 (40.8%) had GS upgrading from ≤6 on biopsy to 7 or higher at the time of the prostatectomy. Independent predictors of pathological upgrading were prostate volume <40 cc (p < 0.001), maximum percent of cancer in any core (p = 0.011), and >1 core positive for cancer (p < 0.001).Conclusions: When obtaining an extended-core biopsy scheme, patients with small prostates (≤40 cc), greater than 1 core positive for cancer, and an increased burden of cancer are associated with increased risk of GS upgrading. Patients with GS ≤6 on biopsy with these pathological parameters should be carefully counselled on treatment decisions.

Introduction: We have seen an increased risk of infectious complications following transrectal ultrasound-guided prostate biopsy (TRUS-PB). Fluoroquinolone (FQ) antibiotics are common for prophylaxis prior to TRUS-PB. We evaluate whether increasing FQ resistance correlates with increased incidence of post-biopsy infectious complications at our institution.Methods: We conducted a retrospective chart and electronic health record review on 927 patients who underwent TRUS-PB between January and July of 2012 in Calgary, Alberta, Canada. We prospectively collected the following variables: age, pre-biopsy prostate-specific antigen, and date of biopsy. We documented presentation to an emergency department within 30 days of TRUS-PB for infectious and non-infectious complications.Results: Of the 927 patients, 58 patients (6.3%) were admitted to the emergency department due to post-TRUS-PB complications within 30 days post-biopsy. The most common infectious complications were sepsis in 21 patients (2.2%), followed by urinary tract infection (UTI) in 9 (0.9%), and prostatitis in 4 (0.4%). We found that 83% of the septic episodes and 66.6% of the UTIs were attributed to ciprofloxacin resistant Escherichia coli (E. coli). The incidence of non-infectious complications was as follows: urinary retention in 12 (1.2%), hematuria in 9 (0.9%), and rectal bleeding in 8 (0.8%).Conclusion: Our results suggest an increased incidence of infectious complications caused by FQ resistant organisms following TRUS-PB. This finding could be attributed to increasing community resistance to ciprofloxacin. The current antimicrobial prophylactic regimen needs to be re-evaluated, and a novel approach may need to be considered.

Background: Needle biopsy of the prostate is a diagnostic method for prostate cancer which is a relatively safe method with low risk of serious complications. The evidences regarding the occurrence of erectile dysfunction following prostate biopsy are controversial. Herein, we aimed at determining the rate of erectile dysfunction in those undergoing transrectal ultrasound-guided prostate biopsy. Method: All candidates for prostate biopsy were enrolled. The International Index of Erectile Function-5 was completed 1 m before and 1, 3, and 6 months after ultrasound-guided prostate biopsy by each patient for erectile dysfunction. Patients with a previous history of erectile dysfunction which due to a positive pathology had received any type of treatment were excluded from the study. Results: Eighty patients with the mean age of 64.8 years, the mean prostate-specific antigen level of 11.64 ng/dL, and the mean prostate volume of 62.43 cc were included. The prostate biopsy result was positive in 38.8% of the cases. No significant relationship was found between erectile dysfunction and prostate-specific antigen level, prostate volume, and the pathology result (P = 0.320, 0.509, and 0.131). The mean questionnaire score 1 month before and after the biopsy was 23 and 18, respectively; it demonstrated a significant difference (P < 0.001). The same score was 17 and 14.5 three and six months after biopsy. The mean score 1 m before and 3 m after biopsy also revealed a significant difference (P < 0.001). Conclusion: Transrectal ultrasound-guided needle biopsy of the prostate causes progressive erectile dysfunction in these patients. This relationship is not affected by the biopsy result, prostate volume, or the prostate-specific antigen level.

Biopsy Gleason Score

Background: Biopsy Gleason score (GS), in combination with other clinical parameters, is important to take a therapeutic decision for patients with diagnosis of localized prostate cancer. However, preoperative GS is often upgraded after a radical prostatectomy. Increasing the amount of tissue in prostate biopsy may be a way to avoid this issue. We evaluate the influence of a larger biopsy needle size on the concordance between biopsy and pathological GS.Methods: We analyzed paired biopsies and prostatectomy specimens from 104 cases of men with clinically localized prostate cancer. At the time of prostate biopsy, the patients were prospectively randomized into two needle groups (16-Gauge [G] and 18G) using a 1:1 ratio. GS concordance was estimated performing kappa statistic testing, overall concordance rate and risk to under grade biopsy GS=6. A logistic regression analysis was performed to evaluate the patients’ characteristics as possible risk factors.Results: The overall concordance between prostate biopsy and pathological GS was 76.9% and 75.6% (p = 0.875) and the k values were 0.821 and 0.811 (p = 0.424), respectively, for 16G and 18G needle study groups. The risk to undergrade a biopsy GS=6 was 21.1% and 15.4% (p = 0.709) using a 16G and 18G needle, respectively. Age, prostate-specific antigen, prostate volume and needle calibre were not independently associated with a higher risk of GS discordance.Conclusions: Needle size does not affect the concordance between biopsy and pathological GS. Although GS is not the only way to determine treatment, it is still an unresolved urological issue.

Objectives: To estimate the ratio between urinary prostate specific antigen (uPSA) and tumor volume after prostate biopsy. Methods: From 2000 to July 2008, uPSA concentration was determined in 60 patients with clinically organ-confined prostate cancer (PCa). All patients underwent six-area transrectal ultrasound (TRUS) - guided biopsy, with at least 12 biopsy cores. Single pathologist determined tumor grade (G), Gleason score (GS), the percentage of tumor infiltration (% TI) and the percentage of positive cores (% PC) in all biopsy cores. Additionally, relative tumor-biopsy volume (RTV) was calculated by multiplying % PC, % TI and prostate ultrasound- derived volume (Vol). Forty-one patients underwent retropubic radical prostatectomy (RRP), while 19 patients underwent radiation therapy. Results: Average uPSA was 308.6+311.9 ng/ml (range 0.06-988 ng/ml), average PSA was 9.7+ 5.5 ng/ml (range 1.2-24.3 ng/ml), tumor grade 1.7+ 0.8, Gleason score 5.2 + 1.3, the percentage of tumor infiltration 27.6+21.8 %, and the percentage of positive cores, 52.2+30.7 %. Average RTV was 6.3+ 8.4 ml (0.29-56 ml). All patients were divided in two groups: I, with RTV 4 ml and II, with RTV = 4 ml. The patients with RTV 4 ml had lower G (1.4 0.6 vs. 2.1+0.8, p=0.0002), lower GS (4.5+1 vs. 5.8+1.3, p=0.003) and higher uPSA (389.4+340.8 vs. 193.1 +229.7, p=0.014). There were no differences in serum PSA levels between the groups. Conclusion: Relative tumor-biopsy volume (RTV) is useful parameter in the preoperative assessment of tumor volume. Patients with higher RTV had significantly higher G and GS. However, these patients had significantly lower uPSA. This phenomenon could be the consequence of compromised PSA drainage from the peripheral zone of the prostate, caused by the tumor.

Abstract BACKGROUND Transrectal ultrasound-guided prostate biopsy (TRUS) is a standard procedure for prostate cancer diagnosis. Because prostate cancer is a multifocal disease in many patients, multiple sampling (n ≥ 10) is required, which may bear the risk of systemic spread of cancer cells. DESIGN Using the standardized CellSearch® system that allows for the detection of single epithelial cell adhesion molecule-positive circulating tumor cells (CTCs) in blood, we investigated whether prostate biopsy is associated with release of prostatic tumor cells into the circulation. Peripheral blood was obtained before and within 30 min after performing prostate biopsy from 115 men with increased serum prostate-specific antigen. RESULTS The number of CTCs significantly increased after biopsy in men with histologically confirmed prostate cancer (odds ratio, 7.8; 95% CI, 4.8–12.8), whereas no biopsy-related changes could be detected in men without confirmed prostate cancer. Multivariable analysis showed that biopsy-related increase of CTCs was significantly correlated with a worse progression-free survival (hazard ratio, 12.4; 95% CI, 3.2–48.6) within the median follow-up of 41 months. CONCLUSIONS Prostate biopsies may lead to a tumor-associated release of CTCs into the blood circulation. Larger confirmatory trials with longer follow-up periods are required before any change in clinical practice can be recommended.
