- Abstract
Background: Data on the efficacy and safety of screening for prostate cancer with magnetic resonance imaging (MRI) are needed from studies of follow-up screening., Methods: In a population-based trial that started in 2015, we invited men who were 50 to 60 years of age to undergo prostate-specific antigen (PSA) screening. Men with a PSA level of 3 ng per milliliter or higher underwent MRI of the prostate. Men were randomly assigned to the systematic biopsy group, in which they underwent systematic biopsy and, if suspicious lesions were found on MRI, targeted biopsy, or the MRI-targeted biopsy group, in which they underwent MRI-targeted biopsy only. At each visit, men were invited for repeat screening 2, 4, or 8 years later, depending on the PSA level. The primary outcome was detection of clinically insignificant (International Society of Urological Pathology [ISUP] grade 1) prostate cancer; detection of clinically significant (ISUP grade ≥2) cancer was a secondary outcome, and detection of clinically advanced or high-risk (metastatic or ISUP grade 4 or 5) cancer was also assessed., Results: After a median follow-up of 3.9 years (approximately 26,000 person-years in each group), prostate cancer had been detected in 185 of the 6575 men (2.8%) in the MRI-targeted biopsy group and 298 of the 6578 men (4.5%) in the systematic biopsy group. The relative risk of detecting clinically insignificant cancer in the MRI-targeted biopsy group as compared with the systematic biopsy group was 0.43 (95% confidence interval [CI], 0.32 to 0.57; P<0.001) and was lower at repeat rounds of screening than in the first round (relative risk, 0.25 vs. 0.49); the relative risk of a diagnosis of clinically significant prostate cancer was 0.84 (95% CI, 0.66 to 1.07). The number of advanced or high-risk cancers detected (by screening or as interval cancer) was 15 in the MRI-targeted biopsy group and 23 in the systematic biopsy group (relative risk, 0.65; 95% CI, 0.34 to 1.24). Five severe adverse events occurred (three in the systematic biopsy group and two in the MRI-targeted biopsy group)., Conclusions: In this trial, omitting biopsy in patients with negative MRI results eliminated more than half of diagnoses of clinically insignificant prostate cancer, and the associated risk of having incurable cancer diagnosed at screening or as interval cancer was very low.

- Abstract
MRI retains its ability to reduce the harm of prostate biopsies by decreasing biopsy rates and the detection of indolent cancers in population-based screening studies aiming to find clinically significant prostate cancers. Limitations of low positive predictive values and high reader variability in diagnostic performance require optimisations in patient selection, imaging protocols, interpretation standards, diagnostic thresholds, and biopsy methods. Improvements in diagnostic accuracy could come about through emerging technologies like risk calculators and polygenic risk scores to select men for MRI. Furthermore, artificial intelligence and workflow optimisations focused on streamlining the diagnostic pathway, quality control, and assurance measures will improve MRI variability. CLINICAL RELEVANCE STATEMENT: MRI significantly reduces harm in prostate cancer screening, lowering unnecessary biopsies and minimizing the overdiagnosis of indolent cancers. MRI maintains the effective detection of high-grade cancers, thus improving the overall benefit-to-harm ratio in population-based screenings with or without using serum prostate-specific antigen (PSA) for patient selection. KEY POINTS: • The use of MRI enables the harm reduction benefits seen in individual early cancer detection to be extended to both risk-stratified and non-stratified prostate cancer screening populations. • MRI limitations include a low positive predictive value and imperfect reader variability, which require standardising interpretations, biopsy methods, and integration into a quality diagnostic pathway. • Current evidence is based on one-time point use of MRI in screening; MRI effectiveness in multiple rounds of screening is not well-documented., (© 2024.

- Abstract
Background: A prerequisite before introducing a screening program is that the screening examinations are acceptable to participants., Objective: To evaluate the acceptance and bother of prostate cancer screening examinations., Design, Setting, and Participants: The randomized population-based GÖTEBORG-2 prostate cancer screening trial invited >37 000 men for prostate-specific antigen (PSA) testing followed by magnetic resonance imaging (MRI) in case of elevated PSA and prostate biopsy (targeted and/or systematic) if indicated., Outcome Measurements and Statistical Analysis: Participants were asked to fill out a questionnaire and rate the level of bother associated with each examination (PSA, MRI, and prostate biopsy) on a categorical scale ranging from 1 to 5 (1 = "not at all bothersome" and 5 = "very bothersome"), and to rate their willingness to repeat the examinations, by marking an X on a continuous scale ranging from 0 to 10 (0 = "yes, without any hesitation" and 10 = "no, absolutely not"). Wilcoxon signed rank test was used., Results and Limitations: Compliance with MRI was 96% (1790/1872), compliance with biopsy was 89% (810/907), and the response rate to the questionnaire was 75% (608/810). Men who underwent all examinations (n = 577) responded that biopsy was more bothersome than PSA test (p < 0.001) and MRI (p < 0.001). High levels of bother (≥4 out of 5) were reported by 2% (12/577) for PSA test, 8% (46/577) for MRI, and 43% (247/577) for biopsy. Men were more willing to repeat MRI than biopsy (p < 0.001), but the difference was small (median 0.2 [interquartile range 0.1-0.6] vs 0.5 [0.1-2.0])., Conclusions: Biopsies are more bothersome than MRI, but a large majority of men accept to repeat both examinations if necessary. Omitting biopsy for MRI-negative men and shifting to targeted biopsies only will reduce bother for men participating in prostate cancer screening., Patient Summary: We asked men how bothersome they found the prostate-specific antigen (PSA) test, magnetic resonance imaging (MRI), and prostate biopsies. Biopsies were more bothersome than PSA and MRI, but most men were willing to repeat all procedures if necessary., (Copyright © 2023 The Author(s). Published by Elsevier B.V.

- Abstract
Background: The European Union recently recommended evaluation of the feasibility of organised prostate cancer screening. In Sweden, regional population-based organised prostate cancer testing (OPT) programmes were introduced in 2020., Objective: To describe initial participation rates and diagnostic outcomes., Design, Setting, and Participants: The three most populated Swedish regions invited all men aged 50 yr to OPT by a letter in 2020-2022. Men with prostate-specific antigen (PSA) ≥3 ng/ml were referred for prostate magnetic resonance imaging (MRI). PSA assays differed across regions. Men with Prostate Imaging Reporting and Data System (PI-RADS) 1-3 and PSA density ≥0.15 ng/ml/cm
3 or PI-RADS 4-5 were referred for a biopsy. Data were obtained from the Swedish Register for Organised Prostate Cancer Testing., Outcome Measurements and Statistical Analysis: Overall and regional participation rates, PSA distributions, PI-RADS score distributions, cancer detection, and treatment were evaluated., Results and Limitations: A total of 23 855 (35%) of 68 060 invited men participated; 696 (2.9%) had PSA ≥3 ng/ml, and of them, 306 (44%) had a biopsy indication and 221 (32%) had a biopsy. On biopsy, 93 (42%) had Gleason grade group ≥2 (0.39% of PSA-tested men) and 44 (20%) Gleason grade group 1 cancer. Most men with cancer had treatment with curative intent (70%) or were under active surveillance (28%). Across regions, proportions of men with PSA ≥3 ng/ml ranged from 2.3% to 4.0%, and those with PI-RADS score 4-5 ranged from 12% to 21%. A limitation is that results are applicable only to first testing of men in their early 50s., Conclusions: The OPT programmes are feasible with good compliance to the diagnostic pathway. The use of MRI and PSA density avoided a biopsy for over half of the men with PSA ≥3 ng/ml. Inter-regional differences in diagnostic outcomes show a need for standardisation of the diagnostic pathway's components., Patient Summary: We report the diagnostic outcomes of inviting 68 000 50-yr-old men to organised prostate cancer testing., (Copyright © 2023 The Author(s).

- Abstract
Background: The European Association of Urology guidelines recommend a risk-based strategy for prostate cancer screening based on the first prostate-specific antigen (PSA) level and age., Objective: To analyze the impact of the first PSA level on prostate cancer (PCa) detection and PCa-specific mortality (PCSM) in a population-based screening trial (repeat screening every 2-4 yr)., Design, Setting, and Participants: We evaluated 25589 men aged 55-59 yr, 16898 men aged 60-64 yr, and 12936 men aged 65-69 yr who attended at least one screening visit in the European Randomized Study of Screening for Prostate Cancer (ERSPC) trial (screening arm: repeat PSA testing every 2-4 yr and biopsy in cases with elevated PSA; control arm: no active screening offered) during 16-yr follow-up (FU)., Outcome Measurements and Statistical Analysis: We assessed the actuarial probability for any PCa and for clinically significant (cs)PCa (Gleason ≥7). Cox proportional-hazards regression was performed to assess whether the association between baseline PSA and PCSM was comparable for all age groups. A Lorenz curve was computed to assess the association between baseline PSA and PCSM for men aged 60-61 yr., Results and Limitations: The overall actuarial probability at 16 yr ranged from 12% to 16% for any PCa and from 3.7% to 5.7% for csPCa across the age groups. The actuarial probability of csPCa at 16 yr ranged from 1.2-1.5% for men with PSA <1.0 ng/ml to 13.3-13.8% for men with PSA ≥3.0 ng/ml. The association between baseline PSA and PCSM differed marginally among the three age groups. A Lorenz curve for men aged 60-61 yr showed that 92% of lethal PCa cases occurred among those with PSA above the median (1.21 ng/ml). In addition, for men initially screened at age 60-61 yr with baseline PSA <2 ng/ml, further continuation of screening is unlikely to be beneficial after the age of 68-70 yr if PSA is still <2 ng/ml. No case of PCSM emerged in the subsequent 8 yr (up to age 76-78 yr). A limitation is that these results may not be generalizable to an opportunistic screening setting or to contemporary clinical practice., Conclusions: In all age groups, baseline PSA can guide decisions on the repeat screening interval. Baseline PSA of <1.0 ng/ml for men aged 55-69 yr is a strong indicator to delay or stop further screening., Patient Summary: In prostate cancer screening, the patient's baseline PSA (prostate-specific antigen) level can be used to guide decisions on when to repeat screening. The PSA test when used according to current knowledge is valuable in helping to reduce the burden of prostate cancer., (Copyright © 2023 The Author(s). Published by Elsevier B.V.

- Abstract
Background: Screening for prostate cancer is burdened by a high rate of overdiagnosis. The most appropriate algorithm for population-based screening is unknown., Methods: We invited 37,887 men who were 50 to 60 years of age to undergo regular prostate-specific antigen (PSA) screening. Participants with a PSA level of 3 ng per milliliter or higher underwent magnetic resonance imaging (MRI) of the prostate; one third of the participants were randomly assigned to a reference group that underwent systematic biopsy as well as targeted biopsy of suspicious lesions shown on MRI. The remaining participants were assigned to the experimental group and underwent MRI-targeted biopsy only. The primary outcome was clinically insignificant prostate cancer, defined as a Gleason score of 3+3. The secondary outcome was clinically significant prostate cancer, defined as a Gleason score of at least 3+4. Safety was also assessed., Results: Of the men who were invited to undergo screening, 17,980 (47%) participated in the trial. A total of 66 of the 11,986 participants in the experimental group (0.6%) received a diagnosis of clinically insignificant prostate cancer, as compared with 72 of 5994 participants (1.2%) in the reference group, a difference of -0.7 percentage points (95% confidence interval [CI], -1.0 to -0.4; relative risk, 0.46; 95% CI, 0.33 to 0.64; P<0.001). The relative risk of clinically significant prostate cancer in the experimental group as compared with the reference group was 0.81 (95% CI, 0.60 to 1.1). Clinically significant cancer that was detected only by systematic biopsy was diagnosed in 10 participants in the reference group; all cases were of intermediate risk and involved mainly low-volume disease that was managed with active surveillance. Serious adverse events were rare (<0.1%) in the two groups., Conclusions: The avoidance of systematic biopsy in favor of MRI-directed targeted biopsy for screening and early detection in persons with elevated PSA levels reduced the risk of overdiagnosis by half at the cost of delaying detection of intermediate-risk tumors in a small proportion of patients.

- Abstract
Background: Studies have suggested associations between greater age, increased risk of prostate cancer (PC), and higher Gleason score., Objective: The present study aimed at investigating these associations within the Göteborg-1 randomized, population-based PC screening trial., Design, Setting, and Participants: The screening arm of the Göteborg-1 screening trial comprises 10000 randomly selected men (aged 50-64 yr at randomization) from the Göteborg region of Sweden. Between 1995 and 2014, they were biennially invited to prostate-specific antigen (PSA) testing to an upper age limit of 70 yr (range 67-71 yr). PSA ≥3 ng/ml triggered a prostate biopsy (sextant biopsy 1995-2009, thereafter a ten-core biopsy)., Outcome Measurements and Statistical Analysis: The impact of age on Gleason score, given a screen-detected PC, was investigated with multinomial logistic regression analyses adjusted for year of testing and screening round., Results and Limitations: Overall, 7625 men had at least one PSA test and 1022 men were diagnosed with PC. For men with screen-detected PC, age was associated with the risk of clinically significant PC above and beyond screening round and year of testing (p < 0.001). For each 1-yr increase in age, the risk of being diagnosed with a Gleason score ≥3 + 4 cancer (vs <7) increased by 11% (95% confidence interval [CI] 4.7-17), whereas the risk of being diagnosed with a Gleason score ≥4 + 3 cancer (vs <7) increased by 8.5% (95% CI -1.6 to 20)., Conclusions: The increased risk of a higher Gleason score in older men should be considered when counseling men regarding early diagnosis and treatment for PC., Patient Summary: We found that older age increased both the risk of prostate cancer and the risk of more aggressive prostate cancer., (Copyright © 2022 The Authors.

- Abstract
Purpose: Our goal was to analyze results from 22 years of followup in the Göteborg randomized prostate cancer (PC) screening trial., Materials and Methods: In December 1994, 20,000 men born 1930-1944 were randomly extracted from the Swedish population register and were randomized (1:1) into either a screening group (SG) or to a control group (CG). Men in the SG were repeatedly invited for biennial prostate specific antigen testing up to an average age of 69 years. Main endpoints were PC incidence and mortality (intention-to-screen principle)., Results: After 22 years, 1,528 men in the SG and 1,124 men in the CG had been diagnosed with PC. In total, 112 PC deaths occurred in the SG and 158 in the CG. Compared with the CG, the SG showed a PC incidence rate ratio (RR) of 1.42 (95% CI, 1.31-1.53) and a PC mortality RR of 0.71 (95% CI, 0.55-0.91). The 22-year cumulative PC mortality rate was 1.55% (95% CI, 1.29-1.86) in the SG and 2.13% (95% CI, 1.83-2.49) in the CG. Correction for nonattendance (Cuzick method) yielded a RR of PC mortality of 0.59 (95% CI, 0.43-0.80). Number needed to invite and number needed to diagnose was estimated to 221 and 9, respectively. PC death risk was increased in the following groups: nontesting men, men entering the program after age 60 and men with >10 years of followup after screening termination., Conclusions: Prostate specific antigen-based screening substantially decreases PC mortality. However, not attending, starting after age 60 and stopping at age 70 seem to be major pitfalls regarding PC death risk. more...

- Abstract
Background: Identification of intervention-related deaths is important for an accurate assessment of the ratio of benefit to harm in screening trials., Objective: To investigate intervention-related deaths by study arm in the European Randomized Study of Prostate Cancer Screening (ERSPC)., Design Setting and Participants: ERSPC is a multicenter trial initiated in the 1990s to investigate whether screening on the basis of prostate-specific antigen (PSA) can decrease prostate cancer mortality. The present study included men in the core age group (55-69 yr: screening group n = 112 553, control group n = 128 681) with 16-yr follow-up., Outcome Measurements and Statistical Analysis: Causes of death among men with prostate cancer in ERSPC were predominantly evaluated by independent national committees via review of medical records according to a predefined algorithm. Intervention-related deaths were defined as deaths caused by complications during the screening procedure, treatment, or follow-up. Descriptive statistics were used for the results., Results and Limitations: In total, 34 deaths were determined to be intervention-related, of which 21 were in the screening arm and 13 in the control arm. The overall risk of intervention-related death was 1.41 (95% confidence interval 0.99-1.99) per 10 000 randomized men for both arms combined and varied among centers from 0 to 7.0 per 10 000 randomized men. A limitation of this study is that differences in procedures among centers decreased the comparability of the results., Conclusions: Intervention-related deaths were rare in ERSPC. Monitoring of intervention-related deaths in screening trials is important for assessment of harms., Patient Summary: We investigated deaths due to screening or treatment to assess harm in a trial of prostate cancer screening. Few such deaths were identified., (© 2021 The Author(s).) more...

- Abstract
Background: Reports on possible benefits for continence with nerve-sparing (NS) radical prostatectomy have expanded the indications beyond preservation of erectile function. It is unclear whether NS surgery affects oncological outcomes., Objective: To determine whether the degree of NS during radical prostatectomy influences oncological outcomes., Design Setting and Participants: Of 4003 patients enrolled in a prospective, controlled trial comparing open and robotic radical prostatectomy during 2008-2011, we evaluated 2401 patients who received robotic radical prostatectomy at seven Swedish centres. Patients were followed for 8 yr., Outcome Measurements and Statistical Analysis: Data for recurrence and positive surgical margin status were assessed using validated patient questionnaires, patient interviews, and clinical record forms before and at 3, 12, and 24 mo and 6 and 8 yr after surgery. Cox and logistic regressions were used to model the effect on recurrence and positive surgical margins (PSM), respectively., Results and Limitations: A total of 481 men had PSM and 467 experienced recurrence during follow-up. Median follow-up for men without recurrence was 6.6 yr. There were no statistically significant differences in recurrence rate between degrees of NS. The PSM rate was significantly higher with a higher degree of NS: interfascial NS, odds ratio (OR) 2.32 (95% confidence interval [CI] 1.69-3.16); intrafascial NS, OR 3.23 (95% CI 2.17-4.80). Recurrence rates were higher for patients with pT2 disease and PSM (hazard ratio [HR] 3.32, 95% CI 2.43-4.53) than for patients with pT3 disease without PSM (HR 2.08, 95% CI 1.66-2.62). The lack of central review of pathological specimens is a limitation., Conclusions: A higher degree of NS significantly increased the risk of PSM but did not significantly increase the risk of cancer recurrence. Combined with the known functional benefits of NS surgery, these results underscore the need to identify an individualised balance., Patient Summary: In this report we looked at the effect of a nerve-sparing approach during removal of the prostate on cancer outcomes for patients having robot-assisted surgery at seven Swedish hospitals. We found that a high degree of nerve-sparing increased the rate of cancer positivity at the margins of surgical specimens and that positive surgical margins increased the risk of recurrence of prostate cancer., (© 2021 The Authors.) more...

- Abstract
Background and Objective: Few studies have investigated the association between surgical volume and outcome of robot-assisted radical prostatectomy (RARP) in an unselected cohort. We sought to investigate the association between surgical volume with peri-operative and short-term outcomes in a nation-wide, population-based study group., Methods: 9,810 RARP's registered in the National Prostate Cancer Register of Sweden (2015-2018) were included. Associations between outcome and volume were analyzed with multivariable logistic regression including age, PSA-density, number of positive biopsy cores, cT stage, Gleason score, and extent of lymph node dissection., Results: Surgeons and hospitals in the highest volume group compared to lowest group had shorter operative time; surgeon (OR 9.20, 95% CI 7.11-11.91), hospital (OR 2.16, 95% CI 1.53-3.06), less blood loss; surgeon (OR 2.58. 95% CI 2.07-3.21) hospital (no difference), more often nerve sparing intention; surgeon (OR 2.89, 95% CI 2.34-3.57), hospital (OR 2.02, 95% CI 1.66-2.44), negative margins; surgeon (OR 1.90, 95% CI 1.54-2.35), hospital (OR 1.28, 95% CI 1.07-1.53). There was wide range in outcome between hospitals and surgeons with similar volume that remained after adjustment., Conclusions: High surgeon and hospital volume were associated with better outcomes. The range in outcome was wide in all volume groups, which indicates that factors besides volume are of importance. Registration of surgical performance is essential for quality control and improvement., Competing Interests: RAG has received lecture fees from IPSEN and Astellas.

- Abstract
Background: Vesicourethral anastomotic stenosis is a well-known late complication after open radical retropubic prostatectomy (RRP) with previously reported incidences of 2.7-15%. There are few reports of the incidence after robot-assisted laparoscopic radical prostatectomy (RALP) compared with RRP., Objective: The aim was to compare the risk of developing symptomatic stenosis after RRP and RALP, and to explore potential risk factors and the influence of stenosis on the risk of urinary incontinence., Design, Setting, and Participants: Between 2008 and 2011, 4003 men were included in a prospective trial comparing RRP and RALP at 14 Swedish centres. Clinical data and patient questionnaires were collected before, during, and after surgery., Outcome Measurements and Statistical Analysis: Stenosis was identified by either patients' reports in questionnaires or case report forms. The primary endpoint is reported as unadjusted as well as adjusted relative risks (RRs), calculated with log-binomial regression models. Data on incontinence were analysed by means of a log-binomial regression model, with stenosis as an independent and incontinence as a dependent variable., Results and Limitations: Symptomatic stenosis developed in 1.9% of 3706 evaluable men within 24 mo. The risk was 2.2 times higher after RRP than after RALP (RR 2.21, 95% confidence interval [CI] 1.38-3.53). Overall, urinary incontinence was twice as common in patients who had stenosis (RR 2.01, 95% CI 1.43-2.64)., Conclusions: This large prospective study found an overall low rate of vesicourethral anastomotic stenosis after radical prostatectomy, but the rate was significantly lower after robot-assisted prostatectomy. The risk of stenosis seems to be associated with the number of sutures/takes in the anastomosis, but this was statistically significant only in the RALP group., Patient Summary: We investigated the risk of developing vesicourethral anastomotic stenosis after open and robot-assisted radical prostatectomy. We found that the risk was generally lower than previously reported and lower after robot-assisted radical prostatectomy than after radical retropubic prostatectomy. Urinary incontinence was twice as common in patients with stenosis., (Copyright © 2019 European Association of Urology. Published by Elsevier B.V. All rights reserved.) more...

- Abstract
Objective: To develop and validate a nomogram that identifies men for whom bone scan is unnecessary. Material and methods: The study datasets were derived from the National Prostate Cancer Register (NPCR) of Sweden. All men in the NPCR ≤80 years of age who were diagnosed with intermediate- or high-risk prostate cancer and who had pretreatment bone imaging (
99m Tc MDP scintigraphy, plain x-ray, computed tomography, magnetic resonance imaging, and/or positron emission tomography fused with computed tomography) were included. Men diagnosed from 2015-2016 formed a development dataset and men diagnosed in 2017 formed a validation dataset. Outcome was metastasis on bone imaging as registered in NPCR. Multivariable logistic regression was used to develop a nomogram. Results: In the development dataset 482/5084 men (10%) had bone metastasis, the corresponding percentage in the validation dataset was 282/2554 (11%). Gleason grade group, clinical T stage, and prostate-specific antigen were included in the final model. Discrimination and calibration were satisfactory in both the development (AUC 0.80, 95% CI 0.78-0.82) and validation dataset (AUC 0.80, 95% CI, 0.77-0.82). Compared with using the EAU guidelines' recommendation for selecting men for imaging, using the nomogram with a cut-off at 4% chance of bone metastasis, would have avoided imaging in 519/2068 men (25%) and miss bone metastasis in 10/519 (2%) men in the validation dataset. Conclusion: By use of our nomogram, bone scans of men with prostate cancer can be avoided in a large proportion of men. more...- Published

- Abstract
Objective: We have previously demonstrated protein expression of the extracellular matrix degrading protein ADAMTS5 in the nuclei of urothelial cells in healthy rats. The proteoglycan versican constitutes one of the main substrates for this protease. In this follow up study we investigated a potential co-localization of versican and ADAMTS5 in the urinary bladder wall. Material and Methods: The study was conducted with archive material (paraffin embedded bladder tissue from our previous study, i.e., 8 male Sprague-Dawley rats). Protein expression of versican was investigated by immunohistochemistry. Furthermore, the occurrence of versican mRNA was examined by in-situ hybridization. Results: Positive immunoreactivity for versican was evident in the urothelium but also, weakly, in the detrusor. This expression was localized only in the cytoplasm, leaving the nuclei devoid of reactivity. Interestingly, versican mRNA was only sparsely observed in the urothelial cells. Conclusions: We found by immunohistochemistry that the substrate for ADAMTS5, versican, was localized in the cytosol of urothelial cells. This demonstrates a difference regarding the expression of ADAMTS5, which was emphasized in the nuclei. This could imply an additional, non-enzymatic, function of ADAMTS5 in the urothelium. more...

- Abstract
Introduction: Radical prostatectomy (RP) is a common surgical procedure with a risk of postoperative erectile dysfunction and urinary incontinence. There is a need for data on RP as a basis for quality assurance and benchmarking., Methods: In 2015, prostatectomies in Sweden (PiS) form was implemented in the National Prostate Cancer Register (NPCR) of Sweden with data on pre-, peri- and post-operative variables., Results: Out of all radical prostatectomies performed in 2016 in Sweden, 3096/3881 (80%) were registered in PiS. A total of 2605 (84%) were robot-assisted radical prostatectomy (RARP) and 491 (16%) were RRP (retropubic radical prostatectomy). RARP was performed by 91 surgeons of whom 47% operated more than 25 RP/year; and RRP was performed by 69 surgeons of whom 10% performed more than 25 RP/year. RARP had a longer operative time (median operating time: RARP 155 minutes [IQR 124-190]; RRP 129 minutes [IQR 105-171]; P < .001) but was associated with smaller bleeding (median intraoperative blood loss: RARP 100 mL [IQR 50-200], RRP 700 mL [IQR 500-1100]; P < .001)., Conclusions: We report on a nationwide, population-based register with transparent reporting of data on the performance of radical prostatectomy. These data are needed as a basis for quality assurance with comparisons of results from individual surgeons and hospitals., (© 2019 The Authors.

- Abstract
Background: The European Randomized study of Screening for Prostate Cancer (ERSPC) has previously demonstrated that prostate-specific antigen (PSA) screening decreases prostate cancer (PCa) mortality., Objective: To determine whether PSA screening decreases PCa mortality for up to 16yr and to assess results following adjustment for nonparticipation and the number of screening rounds attended., Design, Setting, and Participants: This multicentre population-based randomised screening trial was conducted in eight European countries. Report includes 182160 men, followed up until 2014 (maximum of 16yr), with a predefined core age group of 162389 men (55-69yr), selected from population registry., Outcome Measurements and Statistical Analysis: The outcome was PCa mortality, also assessed with adjustment for nonparticipation and the number of screening rounds attended., Results and Limitations: The rate ratio of PCa mortality was 0.80 (95% confidence interval [CI] 0.72-0.89, p<0.001) at 16yr. The difference in absolute PCa mortality increased from 0.14% at 13yr to 0.18% at 16yr. The number of men needed to be invited for screening to prevent one PCa death was 570 at 16yr compared with 742 at 13yr. The number needed to diagnose was reduced to 18 from 26 at 13yr. Men with PCa detected during the first round had a higher prevalence of PSA >20ng/ml (9.9% compared with 4.1% in the second round, p<0.001) and higher PCa mortality (hazard ratio=1.86, p<0.001) than those detected subsequently., Conclusions: Findings corroborate earlier results that PSA screening significantly reduces PCa mortality, showing larger absolute benefit with longer follow-up and a reduction in excess incidence. Repeated screening may be important to reduce PCa mortality on a population level., Patient Summary: In this report, we looked at the outcomes from prostate cancer in a large European population. We found that repeated screening reduces the risk of dying from prostate cancer., (Copyright © 2019. Published by Elsevier B.V.) more...

- Abstract
Purpose: We sought to determine long-term outcomes after deferred radical prostatectomy., Materials and Methods: The study population consisted of all 132 men with screening detected prostate cancer who underwent deferred radical prostatectomy from January 1, 1995 to December 31, 2014 after active surveillance in the Göteborg Randomized, Population-based Prostate Cancer Screening Trial. The last date of followup was May 15, 2017. Followup during active surveillance was performed with prostate specific antigen tests every 3 to 6 months and repeat biopsies every 2 to 4 years. Triggers for radical prostatectomy were disease progression based on prostate specific antigen, grade and/or stage, or patient request. Outcomes included adverse pathology findings at radical prostatectomy, defined as Gleason score greater than 3 + 4, extraprostatic extension, positive margins, seminal vesicle invasion and/or N+, whether the index tumor at radical prostatectomy was identified at biopsy and prostate specific antigen relapse-free survival. Kaplan-Meier analysis was performed., Results: Median time from diagnosis to surgery was 1.9 years (IQR 1.2-4.2) and median postoperative followup was 10.9 years (IQR 7.5-14.5). A total of 52 men (39%) experienced at least 1 unfavorable pathology feature at radical prostatectomy. The 10-year prostate specific antigen relapse-free survival was 79.5%. The index tumor was not identified in the diagnostic biopsy in 38 of the 132 men (29%) or at the last repeat biopsy that preceded radical prostatectomy 22 of 105 (21%)., Conclusions: A large proportion of men had unfavorable pathology findings at deferred radical prostatectomy and the index tumor was frequently not identified. There is a clear need for better risk classification and protocols to determine disease progression during active surveillance., (Copyright © 2018 American Urological Association Education and Research, Inc.

- Abstract
Objective: The aim of this study was to investigate whether protein expression of the extracellular matrix-degrading protease ADAMTS5 can be demonstrated in the urinary bladder of healthy rats, and, if so, to determine the localization of this enzyme., Materials and Methods: The experiments were conducted with eight inbred male Sprague-Dawley rats. Immunohistochemistry was used to investigate the expression of ADAMTS5 in the urinary bladder. Negative controls were established by either excluding the primary antibody or applying the antibody after it had been preabsorbed with its immunogenic peptide. Confocal microscopy was used to visualize the distribution of ADAMTS5 in the urinary bladder tissue., Results: Immunoreactivity for ADAMTS5 was demonstrated in the urothelium and in the detrusor. This expression was localized not only in the cytoplasm, but also in the nuclei. Confocal microscopy corroborated these findings., Conclusion: Expression of ADAMTS5 was demonstrated in the cytoplasm as well as in the nuclei of the urothelium and detrusor cells, suggesting that it may play a role at the transcriptional level. more...

- Abstract
Objective: This study examined whether previously reported results, indicating that prostate-specific antigen (PSA) screening can reduce prostate cancer (PC) mortality regardless of sociodemographic inequality, could be corroborated in an 18 year follow-up., Materials and Methods: In 1994, 20,000 men aged 50-64 years were randomized from the Göteborg population register to PSA screening or control (1:1) (study ID: ISRCTN54449243). Men in the screening group (n = 9950) were invited for biennial PSA testing up to the median age of 69 years. Prostate biopsy was recommended for men with PSA ≥2.5 ng/ml. Last follow-up was on 31 December 2012., Results: In the screening group, 77% (7647/9950) attended at least once. After 18 years, 1396 men in the screening group and 962 controls had been diagnosed with PC [hazard ratio 1.51, 95% confidence interval (CI) 1.39-1.64]. Cumulative PC mortality was 0.98% (95% CI 0.78-1.22%) in the screening group versus 1.50% (95% CI 1.26-1.79%) in controls, an absolute reduction of 0.52% (95% CI 0.17-0.87%). The rate ratio (RR) for PC death was 0.65 (95% CI 0.49-0.87). To prevent one death from PC, the number needed to invite was 231 and the number needed to diagnose was 10. Systematic PSA screening demonstrated greater benefit in PC mortality for men who started screening at age 55-59 years (RR 0.47, 95% CI 0.29-0.78) and men with low education (RR 0.49, 95% CI 0.31-0.78)., Conclusions: These data corroborate previous findings that systematic PSA screening reduces PC mortality and suggest that systematic screening may reduce sociodemographic inequality in PC mortality. more...

- Abstract
Background: Active surveillance (AS) has become a well-accepted and widely used treatment strategy., Objective: To assess the long-term safety of AS for men with screen-detected prostate cancer (PCa)., Design, Setting, and Participants: All men with screen-detected PCa who had very low-, low-, or intermediate-risk PCa and were managed with AS (January 1, 1995 to December 31, 2014) in the Göteborg screening trial., Intervention: Prostate-specific antigen tests every 3-12 mo, rebiopsies in cases of clinical progression, and every 2-3 yr in men with stable disease. Triggers for intervention were disease progression (prostate-specific antigen, grade, and/or stage) or patient initiative., Outcomes Measurements and Statistical Analysis: Treatment-free, failure-free, PCa-specific, and overall survival. The Kaplan-Meier method and Cox proportional hazards models were used., Results and Limitations: Four-hundred and seventy-four men were managed with AS (median age at diagnosis 66.0 yr, median follow-up 8.0 yr). Two-hundred and two men discontinued AS and initiated treatment. The 10-yr and 15-yr treatment-free survival was 47% and 34%, respectively. The hazard ratio for the treatment for low- and intermediate-risk PCa, compared with very low risk, was 1.4 (95% confidence interval [CI] 1.01-1.94) and 1.6 (95% CI 1.13-2.25). Fifty-four men failed AS. The 10-yr and 15-year failure-free survival was 87% and 72%, respectively. These estimates were 94% and 88% for the very low-risk group, 85% and 77% for the low-risk group, and 73% and 40% for the intermediate-risk group. The hazard ratio for failure for low- and intermediate-risk PCa, compared with very low-risk, was 2.2 (95% CI 1.05-4.47) and 4.8 (95% CI 2.44-9.33). Six men died from PCa and none had very low-risk PCa. The 10-yr and 15-yr PCa-specific survival was 99.5% and 96%, respectively. These estimates were 100% for the very low-risk group, 100% and 94% for the low-risk group, and 98% and 90% for the intermediate-risk group. No predefined protocol was used., Conclusions: AS is safe for men with very low-risk PCa, but for men with low- and intermediate-risk PCa, AS carries a risk of missing the possibility of being able to cure the cancer. It is questionable whether men who are not in the lowest tumor risk group and who have a long remaining life expectancy are suitable candidates for this strategy., Patient Summary: Long-term results from this study indicate that some men will miss their chance of cure with active surveillance and it is questionable whether active surveillance is a suitable strategy for men who are not in the lowest tumor risk group and who have a very long remaining life expectancy., (Copyright © 2016.

- Abstract
Purpose: We investigated the effect of age and number of screens on the risk of prostate cancer diagnosis., Materials and Methods: Since 1995 the Göteborg randomized population based prostate cancer screening trial has invited men biennially for prostate specific antigen testing, until the upper age limit of 70 years. Men with a prostate specific antigen above the threshold of 2.5 ng/ml were recommended further evaluation including 10-core biopsy (sextant before 2009). The present study comprises 9,065 men born between 1930 and 1943 (1944 excluded due to different screening algorithm). Complete attendees were defined as men who accepted all screening invitations (maximum 3 to 9 invitations). The cumulative incidence of prostate cancer was calculated using standard methods., Results: Of the 3,488 (38%) complete attendees 667 were diagnosed with prostate cancer (followup 1995 to June 30, 2014). At age 70 years there was no significant difference in prostate cancer risk among those who started screening at the age of 52 (9 screens), 55 (7 screens) or 60 (5 screens) years. However, the cumulative risk of prostate cancer diagnosis increased dramatically with age, and was 7.9% at age 60, 15% at age 65 and 21% at age 70 for men who had been screened 4 or more times., Conclusions: There was no clear association between risk of prostate cancer and the number of screens. Starting screening at an early age appears to advance the time of prostate cancer diagnosis but does not seem to increase the risk of being diagnosed with the disease. Age at termination of screening is strongly associated with the risk of being diagnosed with prostate cancer., (Copyright © 2016 American Urological Association Education and Research, Inc.
