Abstract
PURPOSE To explore and identify the relevant clinical and pathological predictors leading to biopsy Gleason score upgrading (GSU) in cognitive fusion targeted biopsy (COG-TB) in Chinese patients. METHODS Clinical and pathological information of 496 patients who underwent COG-TB and radical prostatectomy (RP) in our hospital from January 2020 to September 2023 were retrospectively compiled and analyzed. In this study, we screened valuable predictors through univariable and multivariable logistic regression analyses and then constructed predictive models. We draw nomograms to visualize the predictive models. In addition, the discriminatory power of the model was assessed using receiver operating characteristic (ROC) curves. Finally, calibration curves and decision curve analysis (DCA) were used to evaluate the predictive power of the model and the net benefits it could deliver. RESULTS Out of the 496 patients eligible for the study, 279 had a consistent Gleason score (GS) on biopsy and postoperative GS, 191 experienced GSU, and 26 experienced downgrading. Significant associations for GSU were identified for five risk factors through multivariable logistic regression analyses, which included age, prostate volume, BMI, tumor percentage in biopsy tissue, and tumor location. Our model had excellent discriminatory power through ROC analysis. Calibration curves and DCA showed that our model was well calibrated and provided certain benefits for patient treatment decisions. CONCLUSION Age, prostate volume, BMI, tumor percentage in biopsy tissue, and tumor location are risk indicators for predicting GSU in COG-TB. Our prediction model is more suitable for Chinese patients and can assist in accurately evaluating biopsy GS and developing effective treatment plans.

Abstract
Objective: The Gleason score is an essential factor for making decisions about prostate cancer management and its prognosis. Thus, we conducted this research to discover the histologic-grading accuracy of needle biopsy specimens, and to identify preoperative clinical and pathological factors that predict upgrading and downgrading from biopsy to radical prostatectomy specimen. Patients and methods: This study was performed on 570 patients who were referred to the medical centers affiliated with Shiraz University of Medical Sciences and underwent radical prostatectomy from 2013 to 2017. Concordance was evaluated between the Gleason score of needle biopsy and radical prostatectomy specimens. Predictors of upgrades and downgrades were assessed in univariate and multivariate logistic regression analyses. Results: Scores were the same in 50% of cases, downgraded in 26%, and upgraded in 24%. The variables predicting a Gleason score upgrade were higher Prostate specific antigen level, larger tumors, and older age. Lower tumor volume, lower Prostate specific antigen, and low maximum percentage of cancer in cores were predictors of downgrading from Gleason score>6 to ⩽6. Also, Body mass index>30, smaller tumor size, and negative lymph nodes were predictors of downgrading from Gleason score>7 to 7. Conclusion: The correlation between biopsy and Radical prostatectomy Gleason scores was only 50%. After dividing them into the new grading groups, this coordination increased by only 5.6%. Physicians need to consider possible limitations of the Gleason score of biopsy and factors that can be predictive of upgrading to high-risk prostate cancer before making treatment decisions.

Abstract
PURPOSE Accurate assessment of Gleason grade is essential to guiding prostate cancer management. Not all healthcare systems have universal access to prostate MRI. We investigated whether transperineal (TP) prostate biopsies provide more accurate Gleason grading than transrectal (TR) biopsies in MRI-naïve patients. METHODS Consecutive patients undergoing TP and TR systematic prostate needle biopsies from 2011 to 2018 were analysed. Patients who underwent radical prostatectomy (RP) within 180 days of biopsies were included. Patients undergoing MRI prior to biopsies were excluded. Pathological concordance, incidence of Gleason upgrading, and correlation coefficients among biopsies and RP Gleason grade were compared. A sub-analysis for concordance in anterior prostate tumours was conducted. RESULTS 262 patients were included (112 TP; 150 TR), the median age was 63 years, and median time from biopsy to RP was 68 days. Concordance with RP histology for TP was 65% compared to 49% for TR (p = 0.011). Biopsy technique predicted RP concordance independent of the number of cores. Gleason upgrading occurred following 24% of TP versus 33% of TR biopsies. In anterior and apical tumours, upgrading occurred in 19% of TP biopsies and 38% of TR biopsies (p = 0.027). CONCLUSION This study suggests TP approach to prostate biopsies result in improved histological grade accuracy in men whom MRI is not available, even after controlling for number of cores. TP approach also resulted in less upgrading for lesions in the anterior and apical prostate compared to TR.

Abstract
PURPOSE To assess the upstaging/upgrading rates of low-risk prostate cancer (PCa) according to the biopsy scheme used (systematic (SB), targeted biopsies (TB), or both) in the setting of positive pre-biopsy MRI. PATIENTS AND METHODS We included 143 consecutive men fulfilling the Toronto University active surveillance (AS) criteria who underwent a pre-biopsy positive MRI, a combination of SB and software-based fusion TB, and a radical prostatectomy, in two expert centres. The primary endpoints were the pathological upgrading and upstaging rates. Overall unfavourable disease (OUD) was defined by any pT3-4 and/or pN1 and/or ≥ GG 3. RESULTS Using TB alone would have missed 21.7% of cancers including 16.7% of ≥ GG 3. The use of TB was significantly associated with a lower risk of ≥ Grade Group (GG) 3 disease (p < 0.006) in RP specimens. Combination of SB and TB lowered this risk by 39%, compared with TB alone. The biopsy scheme did not affect the upstaging rates which were substantial even in case of combination scheme (from 37 to 46%). OUD was detected in approximately 50% of cases. The presence of high grade on TB was the only independent predictive factor for both ≥ GG 2 (p = 0.015) and ≥ GG 3 (p = 0.023) in RP specimens. CONCLUSIONS High grade on TB biopsies represented the major predictor of upgrading. Combination of SB and TB better defined the sub-group of patients having the lowest risk of reclassification, compared with TB or SB alone. The risk of non-organ-confined disease remained high, and could not be accurately predicted by MRI or systematic/targeted biopsy features.

Abstract
Background A new prostate cancer (PCa) prognostic grading system [Gleason groups (GGs)] has been proposed based on the contemporary Gleason scores (GSs), which has five simplified prognostic categories. The objective of this study was to evaluate the agreement between the GGs of prostate biopsy and radical prostatectomy specimens and to identify predictive factors for upgrading GGs. Methods A total of 5339 cases of RP notified to the Prostate Cancer Outcomes Registry, Victoria, Australia over 6 years (2009–2014) from 46 hospitals, were included. The upgrading was evaluated using the new PCa prognostic grading system, the International Society of Urologic Pathology grade groups, which has five prognostic categories. GG 1 is GS ≤ 6, GG 2 is GS 3 + 4 = 7, GG 3 is GS 4 + 3 = 7, GG 4 is GS 8, and GG 5 is GS 9 and 10. Predictors of upgrading were assessed using univariate and multivariate models. Results The GG of prostate biopsies and RP specimens were concordant in 54.5% of cases, while 31.1% were upgraded and 14.3% were downgraded. Longer time interval between biopsy and RP [44–99 days: odds ratio (OR) = 1.3, 95% confidence interval (CI) = 1.1–1.6; > 99 days: OR = 3.0, 95% CI = 2.4–3.8), and RP performed in a metropolitan hospital (biopsy in a regional hospital: OR = 2.2, 95% CI = 1.6–3.2, biopsy in a metropolitan hospital: OR = 1.7, 95% CI = 1.2–2.2) were significant predictors of GG upgrading. Patients who were diagnosed by transperineal biopsy compared to transrectal ultrasound (OR = 0.6, 95% CI = 0.5–0.8) and higher percentage of positive biopsy cassettes (25–62.5%: OR = 0.7, 95% CI = 0.6–0.8, > 62.5: OR = 0.6, 95% CI = 0.5–0.8) were significantly associated with less likelihood of upgrade. Conclusion The lack of concordance among hospitals may be attributable to the specialist expertise of the pathologist. Expert review of specimens may help to overcome this discordance. Clinicians should consider clinical parameters and potential limitations of the GG at biopsy when making treatment decisions with regard to PCa.

Abstract
INTRODUCTION We analyzed whether expansion of existing active surveillance (AS) protocols to include men with biopsy Gleason score (GS) 3+4 prostate cancer (PCa) would significantly alter pathologic and biochemical outcomes of potential candidates of AS. METHODS Among patients who underwent radical prostatectomy at our center between 2006 and 2013, we identified 577 patients (group A) who preoperatively fulfilled at least one of 6 different AS criteria. Also, we identified 217 patients (group B) with biopsy GS 3+4 but fulfilled non-GS criteria from at least one of 6 AS criteria. Designating group C as expanded group incorporating all patients in group A and B, we compared risk of unfavorable disease (pathologic GS ≥ 4+3 and/or pathologic T stage ≥ pT3a) and biochemical recurrence (BCR)-free survival between groups. RESULTS Rates of unfavorable disease were not significantly different between patients of group A and C who met AS criteria from 5 institutions (all p>0.05), not including University of Toronto (p < 0.001). Also BCR-free survivals were not significantly different between patients in group A and C meeting each of 6 AS criteria (all p > 0.05). Among group B, PSAD > 0.15 ng/mL/cm3 (p = 0.011) and tumor length of biopsy GS 3+4 core > 4 mm (p = 0.007) were significant predictors of unfavorable disease. When these two criteria were newly applied in defining group B, rates of unfavorable disease in group A and B was 15.6% and 14.7%, respectively (p = 0.886). CONCLUSION Overall rate of pathologically aggressive PCa harbored by potential candidates for AS may not be increased significantly with expansion of criteria to biopsy GS 3+4 under most contemporary AS protocols. PSAD and tumor length of biopsy GS 3+4 core may be useful predictors of more aggressive disease among potential candidates for AS with biopsy GS 3+4.

Abstract
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.

Abstract
PURPOSE It is debated whether treatment delay worsens oncologic results in localized prostate cancer (PCa). Few studies have focused on the role of a delay between the time of biopsy and the time of surgery. Thus, we aimed to investigate the effect of the time period between biopsy and surgery on Gleason score upgrading (GSU). MATERIALS AND METHODS A total of 290 patients who underwent radical retropubic prostatectomy in Ankara Training and Research Hospital were included in the study. The biopsy Gleason score, age, total prostate-specific antigen (PSA) value, prostate volumes, and PSA density (PSAD) were analyzed in all patients. The patients were divided into two groups: patients with GSU (group 1) and patients without GSU (group 2). Variables having a p-value of ≤0.05 in the univariate analysis were selected and then evaluated by use of multivariate logistic regression models. Results were considered significant at p<0.05. RESULTS GSU occurred in 121 of 290 patients (41.7%). The mean age of the patients was 66.0±7.2 years in group 1 and 65.05±5.60 years in group 2 (p=0.18). The mean PSA values of groups 1 and 2 were 8.6±4.1 and 8.8±4.3 ng/dL, respectively. The mean prostate volumes of groups 1 and 2 were 43.8±14.1 and 59.5±29.8 mL, respectively. The PSAD of group 1 was significantly higher than that of group 2 (0.20 vs. 0.17, p=0.003). The mean time to surgery was shorter in group 2 (group 1, 52.2±22.6 days; group 2, 45.3±15.5 days; p=0.004). According to the logistic regression, time from biopsy to surgery is important in the prediction of GSU. CONCLUSIONS We suggest that the time period between biopsy and surgery is a significant factor that affects GSU in patients with clinically localized PCa.

Abstract
PURPOSE Gleason score from biopsy specimens is important for prostate cancer (PCa) risk stratification and influences treatment decisions. Gleason score upgrading (GSU) between biopsy and surgical pathology specimens has been reported as high as 50 % and presents a challenge in counseling low-risk patients. While recent studies have investigated predictors of GSU, populations in these studies have been largely Caucasian. We report our analysis of predictors of GSU in a large urban African-American population. METHODS A total of 959 patients with D'Amico low-risk prostate cancer underwent radical prostatectomy at Georgetown University or Washington Hospital Center between January 2005 and July 2012. Race, age, PSA, body mass index (BMI), cancer of the prostate risk assessment (CAPRA) score, and transrectal ultrasound (TRUS) biopsy characteristics (percent of biopsy cores showing adenocarcinoma, highest percent of biopsy core involved with cancer, and measured TRUS prostate volume) were analyzed with both univariate and multivariate analyses to identify significant predictors of GSU while controlling for clinical parameters. RESULTS Of the 959 cases, 288 (30.0 %) were upgraded on final pathologic specimen with approximately 38 % (133/355) of African-American patients experiencing GSU. BMI (P = 0.02), percent positive biopsy cores (P < 0.01) and percent of core involved with cancer (P < 0.01), increasing CAPRA score, and serum PSA were independent predictors of GSU on both uni- and multivariate regression analyses. African Americans had a 73 % increase in the incidence of GSU over other races. CONCLUSION More than a quarter of low-risk prostate cancer patients were upgraded on final pathology in our series. Higher BMI, serum PSA, CAPRA score, percent of cores positive, and percent of cores involved were independent predictors of GSU. Individuals with those clinical parameters may harbor occult high-grade disease and should be carefully counseled on treatment decisions.

Upgrading and downgrading of prostate cancer from biopsy to radical prostatectomy: incidence and predictive factors using the modified Gleason grading system and factoring in tertiary grades. Eur Urol 2012; 61:1019-24. [PMID: 22336380 DOI: 10.1016/j.eururo.2012.01.050] [Citation(s) in RCA: 501] [Impact Index Per Article: 41.8] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/09/2011] [Accepted: 01/31/2012] [Indexed: 11/17/2022]
Abstract
BACKGROUND Prior studies assessing the correlation of Gleason score (GS) at needle biopsy and corresponding radical prostatectomy (RP) predated the use of the modified Gleason scoring system and did not factor in tertiary grade patterns. OBJECTIVE To assess the relation of biopsy and RP grade in the largest study to date. DESIGN, SETTING, AND PARTICIPANTS A total of 7643 totally embedded RP and corresponding needle biopsies (2004-2010) were analyzed according to the updated Gleason system. INTERVENTIONS All patients underwent prostate biopsy prior to RP. MEASUREMENTS The relation of upgrading or downgrading to patient and cancer characteristics was compared using the chi-square test, Student t test, and multivariable logistic regression. RESULTS AND LIMITATIONS A total of 36.3% of cases were upgraded from a needle biopsy GS 5-6 to a higher grade at RP (11.2% with GS 6 plus tertiary). Half of the cases had matching GS 3+4=7 at biopsy and RP with an approximately equal number of cases downgraded and upgraded at RP. With biopsy GS 4+3=7, RP GS was almost equally 3+4=7 and 4+3=7. Biopsy GS 8 led to an almost equal distribution between RP GS 4+3=7, 8, and 9-10. A total of 58% of the cases had matching GS 9-10 at biopsy and RP. In multivariable analysis, increasing age (p<0.0001), increasing serum prostate-specific antigen level (p<0.0001), decreasing RP weight (p<0.0001), and increasing maximum percentage cancer/core (p<0.0001) predicted the upgrade from biopsy GS 5-6 to higher at RP. Despite factoring in multiple variables including the number of positive cores and the maximum percentage of cancer per core, the concordance indexes were not sufficiently high to justify the use of nomograms for predicting upgrading and downgrading for the individual patient. CONCLUSIONS Almost 20% of RP cases have tertiary patterns. A needle biopsy can sample a tertiary higher Gleason pattern in the RP, which is then not recorded in the standard GS reporting, resulting in an apparent overgrading on the needle biopsy.

Abstract
OBJECTIVES Gleason score is important for prostate cancer (CaP) risk stratification and prognostication but has a significant rate of upgrading. We examined the effect of prostate size and age on upgrading of Gleason 6 CaP. MATERIALS AND METHODS A retrospective review was performed of patients with Gleason 6 CaP who underwent radical prostatectomy from 2001 through 2010. Preoperative clinical and pathologic variables were assessed to determine association with risk of upgrading at prostatectomy. RESULTS A total of 1,836 patients were identified with Gleason 6 on prostate biopsy. Upgrading was observed in 543 (29.6%) patients with a final Gleason score of 3+4 in 463 (25.2%), 4+3 in 49 (2.7%), and 8-10 in 31 (1.7%). On univariate logistic regression, age, prostate weight, and PSA were significant predictors of Gleason score upgrading and remained significant on multiple logistic regression. Prostate weight was inversely related to risk of upgrading. To further explore this effect, we performed multiple logistic regression to examine risk of Gleason 6, 7, or 8-10 disease in 2,493 patients with Gleason 6-10 at prostatectomy. After controlling for age and PSA, there was a progressively increased risk of Gleason 6, 7, and 8-10 disease with decreasing prostate weight. CONCLUSIONS Older age, higher PSA, and smaller prostate gland size are associated with increased risk of Gleason score upgrading. The inverse relationship of prostate weight to risk of Gleason upgrading may be related to increased high-grade disease in smaller glands.

Abstract
PURPOSE Low-risk prostate cancer patients clinically eligible for active surveillance can also be managed surgically. We evaluated the pathologic outcomes for this cohort that was treated by radical prostatectomy and devised nomograms to predict patients at risk of upgrading and/or upstaging. MATERIALS AND METHODS Seven hundred and fifty patients treated by radical prostatectomy from Jan 2005 to the present fulfilled conventional active surveillance criteria and formed the study cohort. Preoperative data on standard clinicopathologic parameters were available. The radical prostatectomy specimens were graded and staged, and any upgrading to Gleason sum >6 or upstaging to ≥pT3 ('worsening prognosis') were noted. Multivariable logistic regression models were used to develop predictive nomograms. RESULTS Of the 750 patients, 303 (40.4%) patients were either upgraded or upstaged. Multivariable analysis found that preoperative PSA, number of positive cores, and prostate volume were significantly predictive of worsening prognosis and formed the nomogram criteria. CONCLUSIONS Of patients deemed eligible for active surveillance based on conventional criteria, 40.4% have worse prognostic factors after radical prostatectomy. Current active surveillance criteria may be too relaxed, and the use of nomograms which we have devised, may aid in counseling primary prostate cancer patients considering active surveillance as their therapy of choice.

Abstract
We investigated the clinical significance of large difference (≥ 2 points) between biopsy-derived (bGS) and post-prostatectomy Gleason scores (pGS). At 14 medical centers in Korea, 1,582 men who underwent radical prostatectomy for prostate cancer were included. According to the difference between bGS and pGS, the patients were divided into three groups: A (decreased in pGS ≥ 2, n = 30), B (changed in pGS ≤ 1, n = 1,361; control group), and C (increased in pGS ≥ 2, n = 55). We evaluated various clinicopathological factors of prostate cancer and hazards for biochemical failure. Group A showed significantly higher mean maximal percentage of cancer in the positive cores (max%) and pathological T stage than control. In group C, the number of biopsy core was significantly smaller, however, tumor volume and max% were significantly higher and more positive biopsy cores were presented than control. Worse pathological stage and more margin-positive were observed in group A and C than in control. Hazard ratio for biochemical failure was also higher in group A and C (P = 0.001). However, the groups were not independent factors in multivariate analysis. In conclusion, large difference between bGS and pGS shows poor prognosis even in the decreased group. However it is not an independent prognostic factor for biochemical failure.

Abstract
Prostate cancer is a major health problem as it continues to be the most frequently diagnosed cancer in men in the Western world. While improved early detection significantly decreased mortality, prostate cancer still remains the second leading cause of cancer-related death in Western men. Understanding the mechanisms of prostate cancer initiation and progression should have a significant impact on development of novel therapeutic approaches that can help to combat this disease. The recent explosion of novel high-throughput genetic technologies together with studies in animal models and human tissues allowed a comprehensive analysis and functional validation of the molecular changes. This chapter will summarize and discuss recently identified critical genetic and epigenetic changes that drive prostate cancer initiation and progression. These discoveries should help concentrate the efforts of drug development on key pathways and molecules, and finally translate the knowledge that is gained from mechanistic studies into effective treatments.

Abstract
The clinical significance of atypical glands suspicious for malignancy (atypia) on prostate biopsy is unclear. We studied a cohort of 139 patients with atypia who underwent repeat prostate biopsy. We analyzed clinical and pathological variables that may be associated with cancer on repeat biopsy. Cancer was diagnosed in 41 (29%) of patients with atypia: 26 of 41 (66%) were Gleason 6, 20% were Gleason 7 and 7% were Gleason 8 (Gleason < 6 not reported). There were no significant associations of age, race, family history, PSA, PSA density (PSAd), number of previous biopsies or time to repeat biopsy with cancer diagnosis. In multivariate regression, histological inflammation was associated with an 85% decreased probability of cancer on repeat biopsy (odds ratio; OR 0.15; 95% confidence interval; CI 0.04-0.57; P=0.04). Radical prostatectomy was performed in 14 of 41 (34%) patients with cancer; 6 (43%) were Gleason sum ≥7, 3 (21%) were pT3a and 1 (7%) had lymph node metastases. In conclusion, inflammation was independently associated with a significantly decreased risk of cancer on repeat biopsy. However, some patients with initial atypia have higher-risk prostate cancer. Additional studies are needed to elucidate these associations.

Abstract
OBJECTIVE To examine the rate of Gleason sum upgrading (GSU) from a sum of 6 to a Gleason sum of ≥7 in patients undergoing radical prostatectomy (RP), who fulfilled the recommendations for low dose rate brachytherapy (Gleason sum 6, prostate-specific antigen ≤10 ng/mL, clinical stage ≤T2a and prostate volume ≤50 mL), and to test the performance of an existing nomogram for prediction of GSU in this specific cohort of patients. METHODS The analysis focused on 414 patients, who fulfilled the European Society for Therapeutic Radiation and Oncology and American Brachytherapy Society criteria for low dose rate brachytherapy (LD-BT) and underwent a 10-core prostate biopsy followed by RP. The rate of GSU was tabulated and the ability of available clinical and pathological parameters for predicting GSU was tested. Finally, the performance of an existing GSU nomogram was explored. RESULTS The overall rate of GSU was 35.5%. When applied to LD-BT candidates, the existing nomogram was 65.8% accurate versus 70.8% for the new nomogram. In decision curve analysis tests, the new nomogram fared substantially better than the assumption that no patient is upgraded and better than the existing nomogram. CONCLUSIONS GSU represents an important issue in LD-BT candidates. The new nomogram might improve patient selection for LD-BT and cancer control outcome by excluding patients with an elevated probability of GSU.
