- Background: There are limited prognostic data for locally advanced prostate cancer PCa to guide in the choice of treatment. Objective: To assess mortality in different prognostic categories among men with locally advanced PCa managed with noncurative intent. Design, setting, and participants: We conducted a register-based nationwide cohort study within the Prostate Cancer DataBase Sweden. The entire cohort of locally advanced PCa included 14 908 men. After the exclusion of 2724 (18%) men treated with curative intent, 12 184 men with locally advanced PCa either with local clinical stage T3 or T4 or with T2 with serum levels of prostate-specific antigen (PSA) between 50 and 99 ng/ml and without signs of metastases remained for analysis. Measurements: We followed up the patient cohort in the Cause of Death Register for <= 11 yr and assessed cumulative incidence of PCa -specific death stratified by age and clinical characteristics. Results and limitations: The PCa -specific mortality at 8 yr of follow-up was 28% (95% confidence interval [CI], 25-32%) for Gleason score (GS) 2-6, 41% (95% CI, 38-44%) for GS 7, 52% (95% CI, 47-57%) for GS 8, and 64% (95% CI, 59-69%) for GS 9-10. Even for men aged >85 yr at diagnosis with GS 8-10, PCa was a major cause of death: 42% (95% CI, 37-47%). Men with locally advanced disease and a PSA <4 ng/ml at diagnosis were at particularly increased risk of dying from PCa. One important limitation is the lack of bone scans in 42% of the patient cohort, but results remained after exclusion of patients with unknown metastasis status. Conclusions: The PCa-specific mortality within 8 yr of diagnosis is high in locally advanced PCa, suggesting undertreatment, particularly among men in older age groups. Our results underscore the need for more studies of treatment with curative intent for locally advanced tumors. (C) 2011 European Association of Urology. Published by Elsevier B.V.

- Background: Familial prostate cancer risk estimates are inflated by clinically insignificant low-risk cancer, diagnosed after prostate-specific antigen testing. We provide age-specific probabilities of non-low-and high-risk prostate cancer. Methods: Fifty-one thousand, eight hundred ninety-seven brothers of 32 807 men with prostate cancer were identified in Prostate Cancer data Base Sweden (PCBaSe). Nelson-Aalen estimates with 95% confidence intervals (CIs) were calculated for cumulative, family history-stratified probabilities of any, non-low-(any of Gleason score >= 7, prostate-specific antigen [PSA] >= 10 ng/mL, T3-4, N1, and/or M1) and high-risk prostate cancer (Gleason score >= 8 and/or T3-4 and/or PSA >= 20 ng/mL and/or N1 and/or M1). Results: The population probability of any prostate cancer was 4.8% (95% CI = 4.8% to 4.9%) at age 65 years and 12.9% (95% CI = 12.8% to 12.9%) at age 75 years, of non-low-risk prostate cancer 2.8% (95% CI = 2.7% to 2.8%) at age 65 years and 8.9% (95% CI = 8.8% to 8.9%) at age 75 years, and of high-risk prostate cancer 1.4% (95% CI = 1.3% to 1.4%) at age 65 years and 5.2% (95% CI = 5.1% to 5.2%) at age 75 years. For men with one affected brother, probabilities of any prostate cancer were 14.9% (95% CI = 14.1% to 15.8%) at age 65 years and 30.3% (95% CI = 29.3% to 31.3%) at age 75 years, of non-low-risk prostate cancer 7.3% (95% CI = 6.7% to 7.9%) at age 65 years and 18.8% (95% CI = 17.9% to 19.6%) at age 75 years, and of high-risk prostate cancer 3.0% (95% CI = 2.6% to 3.4%) at age 65 years and 8.9% (95% CI = 8.2% to 9.5%) at age 75 years. Probabilities were higher for men with a stronger family history. For example, men with two affected brothers had a 13.6% (95% CI = 9.9% to 17.6 %) probability of high-risk cancer at age 75 years. Conclusions: The age-specific probabilities of non-low-and high-risk cancer presented here are more informative than relative risks of any prostate cancer and more suitable to use for counseling men with a family history of prostate cancer.

Tidskriftsartikel (refereegranskat)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/cm3 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.

Tidskriftsartikel (refereegranskat)abstract
- Background: Many elderly men with high-risk nonmetastatic prostate cancer (HRnMPCa) do not receive radical treatment, despite the high mortality associated with conservative management. Objective: To investigate how age and comorbidity affect treatment of men with HRnMPCa. Design, setting, and participants: This was an observational nationwide register study during 2001-2012. We identified 19 190 men of <80 yr of age diagnosed with HRnMPCa in the National Prostate Cancer Register of Sweden and 95 948 age-matched men without prostate cancer in the register of the total population. Outcome measurements and statistical analysis: The outcome was the proportion of men with HRnMPCa receiving radical treatment (radical prostatectomy or radiotherapy). Vital status and the Charlson comorbidity index (CCI) were obtained from nationwide registers. The 10-yr survival of men without prostate cancer, stratified by age and CCI, was used as a measure of the life expectancy of the men with prostate cancer. Results and limitations: The proportions receiving radical treatment varied with life expectancy among men younger than 70 yr, whereas use of these treatments did not match the long life expectancy of men in their seventies with CCI 0-1. Only 10% of men aged 75-80 yr with CCI 0 received radical treatment despite 52% probability of 10-yr life expectancy, compared with approximately half of the men younger than 70 yr with a similar life expectancy. The use of radical treatment for HRnMPCa increased with time in all Swedish counties, but a threefold difference between counties remained in 2009-2012 for patients aged 70-80 yr with CCI 0-1. Uncertain external validity is a study limitation, and the impact of physician versus patient preferences on treatment selection could not be assessed. Conclusions: Otherwise healthy men in their seventies with HRnMPCa were less likely to receive radical treatment than younger men with a similar life expectancy, although increasing use of radical treatment was observed during the study period. Our findings highlight the need for improved methods for clinical decision-making, including improved assessment of life expectancy. Patient summary: We performed a nationwide register study that showed that many healthy men in their seventies live for at least another 10 yr. Despite this long life expectancy, men in their seventies with high-risk nonmetastatic prostate cancer were often not treated with radical prostatectomy or radiotherapy, possibly because their life expectancy was underestimated. Our study highlights the need for improved clinical decision-making, which should incorporate an assessment of the patient's life expectancy.

Tidskriftsartikel (refereegranskat)abstract
- Purpose: Prostate cancer among first-degree relatives is a strong risk factor for diagnosis of prostate cancer, and the contribution of heritable factors in prostate cancer etiology is high. We investigated how the concordance of non-low-risk prostate cancer among brothers is affected by their genetic relation.Methods:We identified 4,262 pairs of brothers with prostate cancer in the Prostate Cancer Database Sweden. Their cancers were categorized as low risk (Gleason score 6; clinical stage T1-2, Nx/N0, Mx/M0; and prostate-specific antigen 10 ng/mL) or non-low risk. The odds ratio (OR) for concordance of non-low-risk cancer was calculated with logistic regression for the different types of fraternity (monozygotic twins, dizygotic twins, full brothers, and half-brothers)Results: Among monozygotic twins who both were diagnosed with prostate cancer, the OR for both brothers being in the non-low-risk category was 3.82 (95% CI, 0.99 to 16.72) after adjusting for age and year of diagnosis. Among full brothers, the corresponding adjusted OR was 1.21 (95% CI, 1.04 to 1.39). When the analysis was restricted to brothers who both were diagnosed within 4 years, the results were similar.Conclusion: Non-low-risk prostate cancer has a heritable pattern suggesting shared genetic factors, with the highest concordance among monozygotic twins. Our results suggest that a man whose brother has been diagnosed with a non-low-risk prostate cancer is at a clinically relevant increased risk of developing an aggressive prostate cancer himself.

- Purpose: We investigated whether men with biopsy verified, low grade cancer and a family history of lethal or advanced prostate cancer are at particularly high risk for harboring undetected high grade disease.Materials and Methods: Upgrading and up staging of prostate cancer are common after prostatectomy. In a nationwide population based cohort we identified 6,854 men with low risk prostate cancer who underwent radical prostatectomy. Among these men 1,739 (25%) had a history of prostate cancer in a first-degree relative and 289 (4%) had a first-degree relative with lethal or advanced prostate cancer.Results: Compared to men with no familial occurrence of prostate cancer, the odds ratio for the risk of up staging among men with a familial occurrence of high risk or lethal prostate cancer was 1.06 (95% CI 0.76-1.47). The corresponding odds ratio for upgrading was 1.17 (0.91-1.50).Conclusions: We found no association between family history of prostate cancer and up staging or upgrading after radical prostatectomy.

Tidskriftsartikel (refereegranskat)abstract
- Background: Genetic factors seem to be of greater importance in prostate cancer than in other forms of cancer. Studies have suggested familial concordance in survival, but the extent to which that is due to tumor characteristics is not known. Objective: We hypothesized that a brother of an index case with prostate cancer is at particularly increased risk of prostate cancer with the same tumor differentiation as the index case. Design, setting and participants: We identified 21 930 brothers of index cases with prostate cancer in the Prostate Cancer Data Base Sweden and followed them up for incidence of prostate cancer. Outcome measurements and statistical analysis: The relative risk of Gleason score-specific prostate cancer in the cohort of brothers was estimated by using the standardized incidence ratio (SIR) stratified by Gleason score of the index case. We estimated 95% confidence intervals (CIs) assuming a Poisson distribution. Results and limitations: Among brothers of index cases with Gleason score 8-10 cancer, the SIR was 2.53 (95% CI, 1.97-3.21) for a Gleason score 2-6 cancer and 4.00 (95% CI, 2.63-5.82) for a Gleason score 8-10 cancer. SIR for Gleason score 2-6 cancer among brothers decreased with time since the date of the index cases' diagnoses, whereas the risk of Gleason 8-10 cancer increased over time for brothers of index cases with Gleason 8-10 cancer (p for trend = 0.009). Conclusions: Brothers of men with high-grade prostate cancer are at particularly increased risk of high-grade prostate cancer. Likewise, there is a concordance of less malignant prostate cancers within families. These findings may have direct clinical relevance for counseling men with a family history of prostate cancer.

Tidskriftsartikel (refereegranskat)abstract
- Background: Prostate cancer patients have an increased risk of fractures as a consequence of skeletal metastases and osteoporosis induced by endocrine treatment. Data on incidence of fractures and risks in subgroups of men with prostate cancer are sparse. Our aim with this study is to report the risk of fractures among men with prostate cancer in a nationwide population-based study. Patients and methods: We identified 76,600 Swedish men diagnosed with prostate cancer 1997-2006 in the Prostate Cancer Data Base (PCBaSe) Sweden and compared the occurrence of fractures requiring hospitalisation with the Swedish male population. Results: Only men treated with gonadotropin releasing-hormone (GnRH) agonists or orchiectomy had increased incidence and increased relative risk of fractures requiring hospitalisation. Men treated with GnRH agonists had 9.8 and 6.3/1000 person-years higher incidence of any fracture and hip fracture requiring hospitalisation than the general population. The corresponding increases in incidence for men treated with orchiectomy were 16 and 12/1000 person-years, respectively. Men treated with orchiectomy, GnRH agonists, and antiandrogen monotherapy, had SIR for hip fracture of 2.0 (95% Confidence Interval 1.8-2.2), 1.6 (95% CI 1.5-1.8) and 0.9 (95% CI 0.7-1.1), respectively. Men treated with a curative intent (radical prostatectomy or radiotherapy) or managed with surveillance had no increased risk of fractures. Older men had the highest incidence of fractures while younger men had the highest relative risk. Conclusion: Prostate cancer patients treated with GnRH agonists or orchiectomy have significantly increased risk of fractures requiring hospitalisation while patients treated with antiandrogen monotherapy had no increase in such fractures. In absolute terms the excess risk in men treated with GnRH agonists corresponded to almost 10 extra fractures leading to hospitalisation per 1000 patient-years. Effects on bone density should be considered for men on long-term endocrine treatment. Unwarranted use of orchiectomy and GnRH agonists should be avoided. (C) 2012 Elsevier Ltd. All rights reserved.

- ObjectivesTo assess the use of post radical prostatectomy (RP) urinary incontinence (PPI) surgery and to investigate factors related to its use. MethodsCohort study in Prostate Cancer database Sweden (PCBaSe) of men who underwent primary RP between 1998 and 2012. PPI correction procedures were identified in the Patient Registry. Hazard ratios (HR) and 95% confidence intervals (CIs) of PPI surgeries were estimated. ResultsSeven hundred eighty-two out of 26280 (3%) men underwent PPI surgery at a median time of 3 years after RP. There was an eightfold increase in the absolute number of PPI surgeries during 2000-2014 and a threefold increase in the number per 1000 RPs performed. Factors associated with high use PPI surgery were age >70, HR 1.96 (1.54-2.50), and high hospital RP volume (>100 RPs/year), HR 0.81 (0.66-0.99). There was a 10-fold difference in use of PPI surgery per 1000 RPs between the county with the highest versus lowest use. In a subgroup of men with Patient-Reported Outcome Measures (PROM); severe PPI was reported by 7% of men and 24% of them underwent PPI surgery. ConclusionsThree percent of all men received PPI surgery, with a 10-fold variation among health care providers. Only a quarter of men with severe PPI underwent PPI surgery, suggesting that PPI surgery remains underutilized.
