- 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.

- Lifestyle-related risk factors such as hyperglycemia and dyslipidemia have been associated with several cancers. However, studies exploring their link with prostate cancer (PCa) clinicopathological characteristics are sparse and inconclusive. Here, we investigated the associations between serum metabolic markers and PCa clinicopathological characteristics. The study comprised 14,294 men from the Swedish Apolipoprotein MOrtality RISk (AMORIS) cohort who were diagnosed with PCa between 1996 and 2011. Univariate and multivariable logistic regression were used to investigate the relation between glucose, triglycerides and total cholesterol and PCa risk categories, PSA, Gleason score, and T-stage. Mean age at time of PCa diagnosis was 69 years. Men with glucose levels >6.9 mmol/L tend to have PSA<4 mu g/L, while those with glucose levels of 5.6-6.9 mmol/L had a greater odds of PSA>20 mu g/L compared to PSA 4.0-9.9 mu g/L. Hypertriglyceridemia was also positively associated with PSA>20 mu g/L. Hyperglycemic men had a greater odds of intermediate-and high-grade PCa and advanced stage or metastatic PCa. Similarly, hypertriglyceridemia was positively associated with high-grade PCa. There was also a trend toward an increased odds of intermediate risk localized PCa and advanced stage PCa among men with hypertriglyceridemia. Total cholesterol did not have any statistically significant association with any of the outcomes studied. Our findings suggest that high serum levels of glucose and triglycerides may influence PCa aggressiveness and severity. Further investigation on the role of markers of glucose and lipid metabolism in influencing PCa aggressiveness and severity is needed as this may help define important targets for intervention.

- Purpose: Lifestyle-related conditions such as obesity are associated with prostate cancer progression, but the associations with hyperglycemia and dyslipidemia are unclear. This study, therefore, aims to examine the association of glucose, triglycerides, and total cholesterol with prostate cancer death. Methods: From the Swedish AMORIS cohort, we selected 14,150 men diagnosed with prostate cancer between 1996 and 2011 who had prediagnostic measurements of serum glucose, triglycerides, and total cholesterol. Multivariable Cox proportional hazards regressionmodels were used to determine the hazard ratios for death in relation to the aforementioned metabolic markers. Results: Using clinical cut-off points, a non-significant positive association was observed between glucose and prostate cancer death. When compared to those with glucose in the lowest quartile, those in the highest quartile had greater risk of prostate cancer death (HR 1.19; 95% CI 1.02-1.39). However, neither total cholesterol nor triglycerides were associated with prostate cancer death. Glucose and triglycerides were positively associated with overall, cardiovascular, and other deaths. Hypercholesterolemia was only associated with risk of CVD death. Conclusion: Our results suggest that glucose levels may influence prostate cancer survival, but further studies using repeated measurements are needed to further elucidate how glucose levels may influence prostate cancer progression.

- Purpose We examined associations among comorbidity, treatment decisions and mortality in patients with prostate cancer. Materials and Methods A total of 77,536 men diagnosed with prostate cancer between 1997 and 2006 were identified in PCBaSe Sweden from the National Prostate Cancer Register of Sweden. Logistic, Cox and competing risk regression were used to assess associations among Charlson comorbidity index, treatment and mortality. The Charlson comorbidity index was categorized into no (0), mild (1) and severe comorbidity (2+). Results In men with low risk prostate cancer 5,975 of the 13,245 (45.1%) patients without comorbidity underwent radical prostatectomy compared to 256 of the 1,399 (18.9%) men with severe comorbidity. Following adjustment for age and period of diagnosis, radical prostatectomy was less likely to be offered to men with severe comorbidity (OR 0.48, 95% CI 0.41–0.55). In men with high risk prostate cancer, radiotherapy was more common (range 7.7% to 21.3%) than radical prostatectomy (range 3.0% to 11.2%) regardless of comorbidity burden. All cause and competing cause but not prostate cancer specific mortality were increased in men with severe comorbidity (all cause HR 1.99, 95% CI 1.93–2.05; competing cause sHR 2.66, 95% CI 2.56–2.78; prostate cancer specific sHR 0.98, 95% CI 0.93–1.03). The cumulative probability of prostate cancer death given no death from competing causes was significantly higher in men with severe comorbidity in all risk groups (p <0.01). Conclusions Comorbidity affects treatment choices, and is associated with all cause, competing cause and conditional prostate cancer specific mortality. An increased conditional prostate cancer specific mortality in men with severe comorbidity may reflect less aggressive treatment, impaired tumor defense, lifestyle factors and poor general health behavior.

- Background: Outcomes for many cancer forms are associated with socioeconomic status (SES).We investigated if SES was associated with management and mortality in men with high risk prostate cancer.Material and methods: A nation-wide population-based cohort in Prostate Cancer Data Base Sweden (PCBaSe), a merged database including data on incident prostate cancer identified in the National Prostate Cancer Register (NPCR) between 1997 and 2006. High risk PCa was defined as T3 tumour, and/or Gleason score 8–10 and/or PSA 20–50 ng/mL. Use of bone scan, curative treatment, and mortality in relation to SES was assessed by logistic, Cox, and competing risk regression with hazard ratios (HR), sub-distributed HR and 95% confidence intervals (CI) adjusted for co-morbidity, age, calendar period and clinical subgroups.Results: Amongst 17,522 high risk prostate cancer patients, a bone scan was more often performed in higher white-collar than in blue-collar workers (OR 1.30; 95% CI 1.21–1.40). Amongst men without metastases, the likelihood of intention to treat was higher in higher white-collar workers (OR 1.43; 95% CI 1.28–1.57). In men who received curative treatment, the likelihood was higher to undergo radical prostatectomy for higher white-collar patients (OR 1.29; 95% CI 1.10–1.47). In men without metastases, not only overall mortality was lower amongst higher white-collar workers (HR, 0.76; 95% CI 0.60–0.97), but also prostate cancer-specific mortality (sHR 0.70; 95% CI, 0.49–0.99).Conclusions: We conclude that socioeconomic disparities in the management and mortality in men with high risk prostate cancer exist also within the setting of a National Health Care System aiming to provide care on equal terms to all residents.

- Aim: To explore whether the self-reported psychological distress among men with prostate cancer was to the extent that it required psychiatric treatment. Methods: PCBaSe Sweden, a merged database based on the National Prostate Cancer Register including 97% of all prostate cancers registered as well as age-matched controls. We calculated relative risks and 95% confidence intervals to compare risks of psychiatric treatment due to depression, anxiety, and post-traumatic stress disorder controlling for age and socio-economic factors. We used odds ratios to compare use or no use of antidepressants. Findings: In total 72,613 men with prostate cancer and 217,839 men without prostate cancer were included for analyses. Psychiatric hospitalisation due to depression, anxiety and post-traumatic stress disorder were significantly increased (RR 1.29, (95% CI 1.14-1.45), RR 1.42 (95% CI 1.12-1.80) and RR 1.61 (95% CI 1.16-2.24), respectively). However, hospitalisations due to anxiety were only increased in men with more advanced tumours RR 2.28 (95% CI 1.45-3.57). The use of antidepressants was increased for all men with prostate cancer RR 1.65 (95% CI 1.54-1.77) and treatment strategies RR 1.93 (95% CI 1.75-2.13). Interpretation: Men diagnosed with prostate cancer had increased risk of psychiatric treatment for depression, post-traumatic stress disorder and use of antidepressants regardless of risk group and treatment strategy compared to age-matched controls, whilst more advanced prostate cancer was associated with severe anxiety disorders.

- Background Family history is a strong risk factor for prostate cancer. The aim of this study was to investigate whether increased diagnostic activity is related to the incidence of prostate cancer among brothers of men with prostate cancer. Methods Data were from the nationwide population-based Prostate Cancer Database Sweden (PCBaSe Sweden), which includes data from the National Prostate Cancer Register, the Swedish Cancer Register, the Register of the Total Population, the Multi-Generation Register, and the Census database. We investigated the relationship of tumor characteristics, time from diagnosis of the index patient (ie, prostate cancer patients in the National Prostate Cancer Register for whom at least one brother and their father could be identified), calendar period, geographic factors, and socioeconomic status to standardized incidence ratios (SIRs) for prostate cancer among 22 511 brothers of 13 975 index patients in PCBaSe Sweden. Results Brothers of index patients with prostate cancer were at increased risk for a diagnosis of prostate cancer (SIR = 3.1, 95% confidence interval [CI] = 2.9 to 3.3). Risk was higher for T1c tumors (SIR = 3.4, 95% CI = 3.2 to 3.8) than for metastatic tumors (SIR = 2.0, 95% CI = 1.5 to 2.6), and risk of T1c tumors was especially high during the first year after the diagnosis of the index patient (SIR = 4.3, 95% CI = 3.8 to 4.9), compared with the following years (SIR range = 2.8–3.3), and for brothers of index patients who had a higher socioeconomic status (SIR = 4.2, 95% CI = 3.7 to 4.7), compared with brothers of index patients with lower socioeconomic status (SIR = 2.8, 95% CI = 2.4 to 3.2). Conclusions Increased diagnostic activity among men with a family history of prostate cancer appears to contribute to their increased risk of prostate cancer and to lead to detection bias in epidemiological and genetic studies of familial prostate cancer.

- Purpose:Risk of suicide is increased among men with prostate cancer. We investigated this association among men with low-risk cancer, usually detected by prostate specific antigen (PSA)-testing.Patients and Methods:Relative risk (RR) of suicide was calculated by use of Poisson regression analysis within the Prostate Cancer data Base Sweden (PCBaSe) 2.0, a nation-wide, population-based database, comparing 105,736 men diagnosed with prostate cancer between 1997-2009 to 528,658 matched prostate cancer-free men.Results:During the first 6 months after diagnosis, there were 38 suicides among men with prostate cancer; incidence rate 0.73 per 1000 person-years (PY) and 30 suicides in the comparison cohort; 0.11 per 1000 PY, corresponding to a RR of suicide of 6.5 (95% confidence interval (CI) 4.0-10). Risk was highest among men with distant metastases, incidence rate 1.25 per 1000 PY, RR 10 (95% CI 5.1-21) but risk was also increased for men with low-risk tumours, incidence rate difference 0.45 per 1000 PY and RR 5.2 (95% CI 2.3-12) and across categories of socioeconomic status and comorbidity. Eighteen months after diagnosis, risk of suicide had decreased to 0.27 per 1000 PY, RR 1.0 (95% CI 0.68-1.5) for low-risk prostate cancer but remained increased among men with metastases, 0.57 per 1000 PY, RR 1.8 (95% CI 1.1-2.9).Conclusion:Although the increase in absolute risk of suicide was modest, our findings reflect the severe psychological stress that prostate cancer patients may experience after diagnosis. The increased risk of suicide observed in men with prostate cancer, including low-risk, calls for increased awareness.

- Introduction: Novel drugs have been shown to prolong life in men with metastatic prostate cancer (PCa) and castration resistant Pca (CRPC). The aim of Patient-overview Prostate cancer (PPC) is to register and report these treatments and their effect.Material and methods: In PPC, a new part of the National Prostate Cancer Register of Sweden data on start and stop of treatments, imaging, prostate specific antigen, clinical assessment of progression and patient reported outcome measures (PROM) are registered from initiation of hormonal treatment. Data are displayed in a graph to inform clinical decisions for individual patients. For research, data in PPC are linked to PCBaSe with information from NPCR and a number of health care registers.Results: In December 2019, 7 882 men had been registered in PPC out of whom 3 912 had reached the CRPC state. Median time to start of androgen receptor targeted drugs (ART) from start of ADT was 4 years (interquartile range IQR 6) for men with primary ADT, and 9 years (IQR 6) and for men with secondary ADT. Out of all men in PCBaSe with a prescription for ART in 2016-2017, PPC captured 1 480/4 055 (36%). There were small differences between men registered/not registered in PPC for cancer characteristics, primary treatment, comorbidity, and time on ADT before start of ART.Conclusion: In PPC, use and effects of novel therapies for advanced Pca are assessed in a real-life setting. PPC data are used as a decision aid, for quality assurance, and in research.
