Rationale: Increased attention to cancer care has instigated altered systems for screening, diagnosis, and management of various types of cancer, such as in the prostate. While such systems very likely have improved the quality of cancer care, they also result in the altered use of specific services, such as magnetic resonance imaging (MRI). Aims and Objective: To study the change in the use of prostate MRI in the Norwegian health care system from 2013 to 2021 and to investigate some reasons for and potential implications of this change. Method: Data from the Norwegian Health Economics Administration (HELFO), The Cancer Registry of Norway and Cause‐of‐death registry at the Norwegian Institute of public health and the health registry of Vestfold Hospital Trust were used for descriptive statistical analysis. Results: The number of MRIs of the prostate increased threefold from 2013 to 2021, representing an extra cost of 2 million USD in 2020. The incidence of prostate cancer was stable at about 5000 cases per year, corresponding to 178 per 100,000 men, indicating no increased overdiagnosis. However, the clinical staging has changed substantially during this period, indicating stage and grade migration. The number of negative biopsies was reduced, and there are three MRIs per reduced negative biopsy. The number of persons on active surveillance increased during the period. However, these changes are partly independent of the increase in the number of MRIs. Conclusion: There was a substantial increase in the number of prostate MRIs and thus an increase in costs. This appears to have contributed to the reduction of negative biopsies, improved staging and increased active surveillance. However, as these effects are partly independent of the increase in MRIs, we need to document the outcomes for patients from prostate MRIs as their opportunity costs are substantial.

Purpose: To describe the predictive value of information on previous benign biopsy for the outcome of MRI-targeted biopsies. Methods: An exploratory analysis was conducted using data from a prospective, multicenter, paired diagnostic study of 532 men undergoing diagnostics for prostate cancer during 2016–2017. All men underwent 1.5 T MRI; systematic prostate biopsies; and MRI-targeted biopsies to MRI lesions with Prostate Imaging Reporting and Data System version 2, PI-RADS ≥ 3. The main outcome was numbers of detected prostate cancer characterized by grade group (GG) where GG ≥ 2 defined clinically significant cancer (csPCa). Results: Men with previous biopsies had significantly more often negative MRI (26% vs. 17%, p < 0.05) compared to men without previous biopsies. Men with previous biopsies showed higher rates of benign biopsies (41% vs. 26%, p < 0.05) and lower rates of GG2 (17% vs. 30%, p < 0.05) and GG ≥ 3 (5% vs. 10%, p < 0.05) cancer. Biopsy-naïve men had higher proportions of highly suspicious MRI lesions (PIRADS 5; p < 0.05) and a higher proportion of significant cancer in those lesions (p = 0.05). In multivariate regression analysis, a previous benign prostate biopsy was associated with less than half the odds of csPCa (OR 0.38; 95% CI 0.20–0.71). Conclusion: In this large prospective multicenter trial, we showed that men with a previous prostate biopsy had higher proportions of MRIs without lesions and lower proportion of highly suspicious lesions than biopsy-naïve men. Further, biopsy-naïve men showed higher detection of clinically significant cancer when using MRI-targeted biopsies. Also, in the era of MRI-targeted biopsy strategies, biopsy history should be carefully considered in biopsy decisions. Trial registration: NCT02788825 (ClinicalTrials.gov).

The Danish Prostate Cancer Registry and a local Norwegian registry at Innlandet Hospital Trust are two exceptions, converting SNOMED coding or structured digital formulas in the clinical workflow to registry data [[5]]. The medical record has during ages served as the main documentation of medical practice and is still mandatory for practicing doctors in most countries. [Extracted from the article]

Background: Older men (aged ≥75 years) with high risk, non‐metastatic prostate cancer (PCa) are increasingly treated with curative therapy (surgery or radiotherapy). However, it is unclear if curative therapy prolongs life and improves health‐related quality of life (HRQoL) in this age group compared to conservative therapy, which has evolved considerably during the last decade. Study Design: The Scandinavian Prostate Cancer Group (SPCG) 19/Norwegian Get‐Randomized Research Group‐Prostate (GRand‐P) is a randomised, two‐armed, controlled, multicentre, phase III trial carried out at study centres in Norway, Denmark, Finland, and Sweden. Endpoints: The primary endpoints are overall survival and HRQoL (burden of disease scale, European Organisation for the Research and Treatment of Cancer [EORTC] Elderly Cancer patients). Secondary endpoints are PCa‐specific survival, metastasis‐free survival, role‐functioning scale (EORTC quality of life questionnaire 30‐item core), urinary irritative/obstructive scale (26‐item Expanded Prostate Cancer Index Composite [EPIC‐26]), bowel scale (EPIC‐26), intervention‐free survival, PCa morbidity, use of secondary and tertiary systemic therapies, mean quality‐adjusted life‐years (QALYs), and mean total healthcare costs. Patients and Methods: A total of 980 men (aged ≥75 years) with non‐metastatic, high‐risk PCa will initially be screened with Geriatric 8 (G8) health status screening tool and Mini‐COG© brief cognitive test. Participants identified by G8 as 'fit' or 'frail' will be randomised (ratio 1:1) to either immediate curative therapy (radiotherapy or prostatectomy) or conservative therapy (endocrine therapy or observation). Participants who are unable or unwilling to participate in randomisation will be enrolled in a separate observation group. Randomised patients will be followed for 10 years. Trial Registration: Ethics approval has been granted in Norway (457593), Denmark (H‐22051998), Finland (R23043) and Sweden (Dnr 2023‐05296‐01). The trial is registered on Clinicaltrials.org (NCT05448547). [ABSTRACT FROM AUTHOR]

The aim of this study was to give a collective overview on all available data sources on bladder cancer patients in the Nordic countries including the amount of detail and coverage. National representatives from five Nordic countries were asked to fill out a questionnaire on available information regarding bladder cancer patients from databases in their respective countries. Additional information was retrieved from descriptions of the relevant registries. Non-muscle invasive bladder cancer: from all countries, information on stage and grade at transurethral resection of the bladder (TURB) could be retrieved. Details on procedures (TURB, instillation therapy, photodynamic diagnosis, and perioperative instillation) were varying within different databases. Muscle invasive bladder cancer: in all Nordic countries, detailed information on cystectomy patients could be retrieved but with variable registration of complications. Completeness of available information on oncological treatment (radiation, chemotherapy, and immunotherapy) were varying. Oncological outcome: Information on overall survival was available in all countries whereas recurrence-free survival and cancer-specific survival were available for some but not all patients depending on treatment modality. Despite limitations, we found that it was possible to retrieve detailed information on diagnostics, treatment, and outcome for most aspects of bladder cancer in the Nordic countries on a population based, non-selected patient cohort.

Objective: To present a code-driven, electronic database for patients TrEated with robotic-assisted radiCaL prostAtectomy (TECLA), developed at Innlandet Hospital (IH), Trust, Norway, for research, local quality control and to deliver data to the National Cancer Registry of Norway (CRN). Clinical data are directly extracted from the structured documentation in the electronic medical record (EMR). Materials and methods: The urological department at IH treats about 200 patients with robotic-assisted radical prostatectomy (RARP) annually. All consenting patients registered with the procedure code for RARP are included in TECLA. Clinical data are obtained automatically from the EMR, by structured forms. Patient-reported outcome and experience measures (PROMs and PREMs) are filled in by the patients on an iPad or a smartphone. Results: The basic construct of TECLA is presented. From August 2017 to June 2018, 200 men were treated with RARP, of which 182 (91%) provided consent for inclusion in the register. Of these, 97% completed the PROM survey before treatment and 91% at 3 months follow-up. PREMs were completed by 78%. All clinical variables for the hospital stay and for the 6-week follow-up were more than 95% complete. Conclusion: This entirely electronic surgical quality register is easy to use, both for patients and clinicians, and has a high capture rate. The data collection is linked to the clinicians' workflow, without double data entry, so entering data does not add any extra work. The register design can be used by other hospitals for various surgical procedures. [ABSTRACT FROM AUTHOR]

Aim Mortality among patients with bladder cancer is usually reported to be higher for women than men, but how the risk differs and why remain largely unexplained. We also described gender-specific differences in survival for patients with bladder cancer and estimated to what extent they can be explained by differences in T-stage distribution at the first diagnosis. Methods The present study comprised all 15,129 new cases of histologically verified invasive and non-invasive urothelial carcinoma of the urinary bladder diagnosed between 1997 and 2011 as registered in the Cancer Registry of Norway. Gender-specific excess mortality risk rates and risk ratios were calculated based on a flexible parametric relative survival model adjusting for T-stage and age, allowing the effect of gender to vary over time. We also present gender-specific relative survival curves for different T-stage patterns adjusted for age. Results Risk rates were significantly higher for women than men up to 2 years after bladder cancer diagnosis, particularly for muscle-invasive cancers. Thereafter, risk rates appeared to be higher in men. Adverse T-Stage distribution in women explained half of the unfavourable survival difference in female patients 2 years after diagnosis. Conclusion The common view of worse bladder cancer prognosis in women than in men needs to be revised. Norwegian women have a less favourable prognosis solely within the first 2 years after diagnosis, particularly when diagnosed with a muscle-invasive tumour; parts of this discrepancy can be attributed to more severe initial diagnoses in women.

Objective: In comparable men with non-metastatic prostate cancer, radical prostatectomy (RP), radiotherapy (RAD) and active surveillance (AS) are treatment options with similar survival rates, but different side-effects. Healthcare professionals consider pretreatment shared decision making (SDM) to be an essential part of medical care, though the patients' view about SDM is less known. In this article, we explore prostate cancer (PCa) patients' SDM wish (SDMwish), and experiences (SDMexp). Material and methods: This is a registry-based survey performed by the Cancer Registry of Norway (2017-2019). One year after diagnosis, 5,063 curatively treated PCa patients responded to questions about their pre-treatment wish and experience regarding SDM. Multivariable analyses identified factors associated with SDM. Statistical significance level: p < 0.05. Results: Overall, 78% of the patients wished to be involved in SDM and 83% of these had experienced SDM. SDMwish and SDMexp was significantly associated with decreasing age, increasing education, and living with a partner. Compared with the RP group, the probability of SDMwish and SDMexp was reduced by about 40% in the RAD and the AS groups. Conclusion: Three of four curatively treated PCa wanted to participate in SDM, and this wish was met in four of five men. Younger PCa patients with higher education in a relationship, and opting for RP, wanted an active role in SDM, and experienced being involved. Effective SDM requires the responsible physicians' attention to the individual patients' characteristics and needs. [ABSTRACT FROM AUTHOR]

Active surveillance (AS) is standard of care for patients with low-risk prostate cancer (PCa), but its feasibility in intermediate-risk patients is controversial. We compared outcomes of low- and intermediate-risk patients managed with multiparametric magnetic resonance imaging (mpMRI)-supported AS in a community hospital. Of the 433 patients enrolled in AS between 2009 and 2016, 358 complied with AS inclusion criteria (Cancer of the Prostate Risk Assessment (CAPRA) score ≤ 5, Gleason grade group (GGG) ≤ 2, clinical stage ≤ cT2 and prostate-specific antigen (PSA) ≤ 20 ng/ml) and discontinuation criteria (histological-, PSA-, clinical- or radiological disease reclassification). Of the 358 patients, 177 (49%) were low-risk and 181 (51%) were intermediate-risk. Median follow-up was 4.2 years. The estimated 5-year treatment-free survival (TFS) was 56% (95% confidence interval [CI] 51–62%). Intermediate-risk patients had significantly shorter TFS compared with low-risk patients (hazard ratio 2.01, 95% CI 1.47–2.76, p < 0.001). There were no statistically significant differences in the rate of adverse pathology, biochemical recurrence-free survival and overall survival between low- and intermediate-risk patients. Two patients developed metastatic disease and three died of PCa. These results suggest that selected patients with intermediate-risk PCa may be safely managed by mpMRI-supported AS, but longer follow-up is necessary. [ABSTRACT FROM AUTHOR]

Background: Lymphovascular invasion (VI) is an established prognostic marker for many cancers including bladder cancer. There is a paucity of data regarding whether the prognostic significance of lymphatic invasion (LVI) differs from blood vessel invasion (BVI). The aim was to examine LVI and BVI separately using immunohistochemistry (IHC), and investigate their associations with clinicopathological characteristics and prognosis. A secondary aim was to compare the use of IHC with assessing VI on standard HAS (hematoxylin-azophloxine-saffron) sections without IHC. Methods: A retrospective, population –based series of 292 invasive bladder cancers treated with radical cystectomy (RC) with curative intent at Vestfold Hospital Trust, Norway were reviewed. Traditional histopathological markers and VI based on HAS sections were recorded. Dual staining using D2–40/CD31 antibodies was performed on one selected tumor block for each case. Results: The frequency of LVI and BVI was 32 and 28%, respectively. BVI was associated with features such as higher pathological stages, positive regional lymph nodes, bladder neck involvement and metastatic disease whereas LVI showed weaker or no associations. Both BVI and LVI independently predicted regional lymph node metastases, LVI being the slightly stronger factor. BVI, not LVI predicted higher pathological stages. BVI showed reduced recurrence free (RFS) and disease specific (DSS) survival in uni-and multivariable analyses, whereas LVI did not. On HAS sections, VI was found in 31% of the cases. By IHC, 51% were positive, corresponding to a 64% increased sensitivity in detecting VI. VI assessed without IHC was significantly associated with RFS and DSS in univariable but not multivariable analysis. Conclusions: Our findings indicate that BVI is strongly associated with more aggressive tumor features. BVI was an independent prognostic factor in contrast to LVI. Furthermore, IHC increases VI sensitivity compared to HAS. [ABSTRACT FROM AUTHOR]

Objective. Hexaminolevulinate (HAL) is an optical imaging agent used with fluorescence cystoscopy (FC) for the detection of non-muscle-invasive bladder cancer (NMIBC). Guidelines from the European Association of Urology (EAU) and a recent, more detailed European expert consensus statement agree that HAL-FC has a role in improving detection of NMIBC and provide recommendations on situations for its use. Since the publication of the EAU guidelines and the European consensus statement, new evidence on the efficacy of HAL-FC in reducing recurrence of NMIBC, compared with white light cystoscopy (WLC), have been published. Material and methods. To consider whether these new trials have an impact on the expert guidelines and on clinical practice (e.g. supporting existing recommendations or providing evidence for a change or expansion of practice), a group of bladder cancer experts from Denmark, Finland, Norway and Sweden met to address the following questions: What is the relevance of the new data on HAL-FC for clinical practice in managing NMIBC? What impact do the new data have on European guidelines? How could HAL-FC be used in clinical practice? and What further information on HAL-FC is required to optimize the management of NMIBC? Results and conclusions. This article reports the outcomes of the discussion at the Nordic expert panel meeting, concluding that, in line with European guidance, HAL-FC has an important role in the initial detection of NMIBC and for follow-up of patients to assess tumour recurrence after WLC. It provides practical advice, with an algorithm on the use of this diagnostic procedure for urologists managing NMIBC. [ABSTRACT FROM AUTHOR]

Background: Cancer patient pathways (CPPs) were implemented in 2015 to reduce waiting time, regional variation in waiting time, and to increase the predictability of cancer care for the patients. The aims of this study were to see if the national target of 70% of all cancer patients being included in a CPP was met, and to identify factors associated with CPP inclusion.Methods: All patients registered with a colorectal, lung, breast or prostate cancer diagnosis at the Cancer Registry of Norway in the period 2015-2016 were linked with the Norwegian Patient Registry for CPP information and with Statistics Norway for sociodemographic variables. Multivariable logistic regression examined if the odds of not being included in a CPP were associated with year of diagnosis, age, sex, tumour stage, marital status, education, income, region of residence and comorbidity.Results: From 2015 to 2016, 30,747 patients were diagnosed with colorectal, lung, breast or prostate cancer, of whom 24,429 (79.5%) were included in a CPP. Significant increases in the probability of being included in a CPP were observed for colorectal (79.1 to 86.2%), lung (79.0 to 87.3%), breast (91.5 to 97.2%) and prostate cancer (62.2 to 76.2%) patients (p < 0.001). Increasing age was associated with an increased odds of not being included in a CPP for lung (p < 0.001) and prostate cancer (p < 0.001) patients. Colorectal cancer patients < 50 years of age had a two-fold increase (OR = 2.23, 95% CI: 1.70-2.91) in the odds of not being included in a CPP. The odds of no CPP inclusion were significantly increased for low income colorectal (OR = 1.24, 95%CI: 1.00-1.54) and lung (OR = 1.52, 95%CI: 1.16-1.99) cancer patients. Region of residence was significantly associated with CPP inclusion (p < 0.001) and the probability, adjusted for case-mix ranged from 62.4% in region West among prostate cancer patients to 97.6% in region North among breast cancer patients.Conclusions: The national target of 70% was met within 1 year of CPP implementation in Norway. Although all patients should have equal access to CPPs, a prostate cancer diagnosis, older age, high level of comorbidity or low income were significantly associated with an increased odds of not being included in a CPP.

Abstract Background More specific diagnostic for prostate cancer is needed to decrease overdetection and number of diagnostic procedures. Objective To assess the performance of combining a blood-based biomarker panel and magnetic resonance imaging (MRI)-targeted biopsies for prostate cancer detection. Design, setting, and participants We used a prospective, multicenter, paired diagnostic study design. A total of 532 men aged 45–74 yr referred for prostate cancer workup were included during 2016–2017. Intervention Participants underwent blood sampling for analysis of the Stockholm3 test including protein biomarkers, genetic polymorphisms, and clinical variables; 1.5 T MRI; systematic prostate biopsies; and MRI-targeted biopsies to lesions with Prostate Imaging Reporting and Data System version 2 ≥3. Outcome measurements and statistical analysis The main outcome was numbers of detected prostate cancer characterized by grade group (GG) and the number of performed biopsies using relative sensitivity (RS). Results and limitations Median prostate-specific antigen was 6.3 ng/ml, and mean age was 63.9 yr. Targeted and systematic biopsies detected 170 and 162 GG ≥2 tumors, respectively (RS 1.05; 95% confidence interval [CI] 0.96–1.14). Compared with performing systematic biopsies on all men, performing targeted and systematic biopsies only on men with >10% risk of GG ≥2 cancer, as predicted by the Stockholm3 test, required 62% (95% CI 58–66) of the biopsy procedures and detected 58% (95% CI 48–70) of GG 1 disease, with increased sensitivity for GG ≥2 detection (RS 1.10; 95% CI 1.02–1.17). Performing only targeted biopsies in men with elevated Stockholm3 test altered these results only slightly. Compared with performing systematic and targeted biopsies on all men, performing this only for men with an elevated Stockholm3 test decreased detection of GG ≥2 cancer slightly (RS 0.92; 95% CI 0.88–0.95). Limitations include lacking knowledge of true disease prevalence. Conclusions These findings provide evidence that strategies combining the blood-based Stockholm3 test and MRI-targeted biopsies can be used to inform biopsy decision making. Patient summary In this study, 532 men coming for prostate cancer workup underwent blood sampling, and both traditional and magnetic resonance imaging/fusion-guided prostate biopsies. We report that performing targeted biopsies only in men with an elevated risk as assessed by the Stockholm3 test saved biopsies, decreased overdetection, and maintained the number of detected high-grade cancers. Take Home Message In this prospective, multicenter study, a strategy of performing magnetic resonance imaging/fusion biopsies in men with an elevated risk of prostate cancer, as assessed by the Stockholm3 test, saved biopsy procedures, decreased detection of low-grade tumors, and maintained sensitivity to detect high-grade cancer.

Objective: This study aimed to determine the level of misattribution of prostate cancer deaths in Norway based on the county of Vestfold in the years 2009-2014. Materials and methods: The study included 328 patients registered as dead from prostate cancer (PCD; part I of death certificate), 126 patients with prostate cancer as other significant condition at death (OCD; part II of death certificate) and 310 patients who died with a diagnosis of prostate cancer not registered on the death certificate (PC-DCneg) in Vestfold County in 2009-2014. The complete cohort with patients’ names and dates of birth was provided by the Norwegian Institute of Public Health and the Norwegian Cancer Registry. The true cause of death of all patients was evaluated based on patient journals. Results: Over-reporting of prostate cancer deaths in the PCD group was 33% while under-reporting in the OCD and PC-DCneg groups was 19% and 5%, respectively. The correlation between registered and observed causes of death was 0.81 (95% confidence interval 0.78-0.83). Misattribution of prostate cancer deaths increased significantly with patient age and decreasing Gleason score. Conclusions: Prostate cancer mortality statistics in Norway are relatively accurate for patients aged <75 years at death. However, overall accuracy of cause of death assignment is significantly reduced by misattribution among older patients (> 75 years), who represent the large majority of prostate cancer deaths. Over-reporting of prostate cancer deaths among elderly people may not be an exclusively Norwegian phenomenon and may affect prostate cancer mortality statistics in other countries.

Background: The high degree of genomic diversity in cancer represents a challenge for identifying objective prognostic markers. We aimed to examine the extent of tumour heterogeneity and its effect on the evaluation of a selected prognostic marker using prostate cancer as a model.Methods: We assessed Gleason Score (GS), DNA ploidy status and phosphatase and tensin homologue (PTEN) expression in radical prostatectomy specimens (RP) from 304 patients followed for a median of 10 years (interquartile range 6-12). GS was assessed for every tumour-containing block and DNA ploidy for a median of four samples for each RP. In a subgroup of 40 patients we assessed DNA ploidy and PTEN status in every tumour-containing block. In 102 patients assigned to active surveillance (AS), GS and DNA ploidy were studied in needle biopsies.Results: Extensive heterogeneity was observed for GS (89% of the patients) and DNA ploidy (40% of the patients) in the cohort, and DNA ploidy (60% of the patients) and PTEN expression (75% of the patients) in the subgroup. DNA ploidy was a significant prognostic marker when heterogeneity was taken into consideration. In the AS cohort we found heterogeneity in GS (24%) and in DNA ploidy (25%) specimens.Conclusions: Multi-sample analysis should be performed to support clinical treatment decisions.

Background: Cancer patient pathways (CPPs) were implemented in Norway to reduce unnecessary waiting times, regional variations, and to increase the predictability of cancer care for the patients. This study aimed to determine if 70% of cancer patients started treatment within the recommended time frames, and to identify potential delays.Methods: Patients registered with a colorectal, lung, breast, or prostate cancer diagnosis at the Cancer Registry of Norway in 2015-2016 were linked with the Norwegian Patient Registry and Statistics Norway. Adjusting for sociodemographic variables, multivariable quantile (median) regressions were used to examine the association between place of residence and median time to start of examination, treatment decision, and start of treatment.Results: The study included 20 668 patients. The proportions of patients who went through the CPP within the recommended time frames were highest among colon (84%) and breast (76%) cancer patients who underwent surgery and lung cancer patients who started systemic anticancer treatment (76%), and lowest for prostate cancer patients who underwent surgery (43%). The time from treatment decision to start of treatment was the main source of delay for all cancers. Travelling outside the resident health trust prolonged waiting time and was associated with a reduced odds of receiving surgery and radiotherapy for lung and rectal cancer patients, respectively.Conclusions: Achievement of national recommendations of the CCP times differed by cancer type and treatment. Identified bottlenecks in the pathway should be targeted to decrease waiting times. Further, CPP guidelines should be re-examined to determine their ongoing relevance. [ABSTRACT FROM AUTHOR]

Objective. This study aimed to assess the prevalence of positive surgical margins (PSM) and urinary incontinence (UI) in relation to surgeons' annual radical prostatectomy (RP) volume. Material and methods. This national study prospectively assessed 521 preoperatively continent patients with prostate cancer (PCa), scheduled for RP by surgeons with high (>50), medium (20-50) or low annual volume (<20) at 14 urological departments in Norway. Patients responded to UI questions from the Expanded Composite Prostate Cancer Index (EPIC-50) before and 1 year after RP. UI was defined as 'use of pad(s)' and/or 'a moderate or severe urinary leakage problem (ULP)'. Preoperative prediction of PSMs and UI was explored in multivariate regression analyses with the following independent variables: surgeons' annual RP volume, type of hospital (university versus community), patient's health, sociodemographic features and PCa characteristics. Results. Based on histopathological reports, the overall PSM rate was 26%, with differences between the high- (18%), medium- (28%) and low-volume (44%) groups. Increasing PSM rates were predicted by surgeons belonging to the low- and medium-volume categories, prostate-specific antigen> 10 µg/l, Gleason score >7, patient age >65 years and <12 years of education. At 1-year follow-up 40% reported UI, without significant differences between the volume groups. Only 46% of those who used pad(s) experienced ULP. UI was predicted by clinical category ≥T2 and community type of hospital, but not by surgeons' annual RP volume. Conclusions. Preoperative counselling should take into account the relationship between surgeon's annual RP volume and PSM rate and the current knowledge about UI and ULP. [ABSTRACT FROM AUTHOR]
