- OBJECTIVE: The incidence of prostate cancer is rising rapidly in Sweden and there is a need to better understand the pattern of diagnosis, tumor characteristics and treatment. MATERIAL AND METHODS: Between 1996 and 2005, all new cases of adenocarcinoma of the prostate gland were intended to be registered in the National Prostate Cancer Register (NPCR). This register contains information on diagnosing unit, date of diagnosis, cause of diagnosis, tumor grade, tumor stage according to the TNM classification in force, serum prostate-specific antigen (PSA) levels at diagnosis and primary treatment given within the first 6 months after diagnosis. RESULTS: In total, 72,028 patients were registered, comprising >97% of all pertinent incident cases of prostate cancer in the Swedish Cancer Register (SCR). During the study period there was a considerable decrease in median age at the time of diagnosis, a stage migration towards smaller tumors, a decrease in median serum PSA values at diagnosis, a decrease in the age-standardized incidence rate of men diagnosed with distant metastases or with a PSA level of > 100 ng/ml at diagnosis and an increase in the proportion of tumors with Gleason score <6. Relatively large geographical differences in the median age at diagnosis and the age-standardized incidence of cases with category T1c tumors were observed. Treatment with curative intent increased dramatically and treatment patterns varied according to geographical region. In men with localized tumors and a PSA level of <20 ng/ml at diagnosis, expectant treatment was more commonly used in those aged > or =75 years than in those aged <75 years. Also, the pattern of endocrine treatment varied in different parts of Sweden. CONCLUSIONS: All changes in the register seen over time are consistent with increased diagnostic activity, especially PSA testing, resulting in an increased number of cases with early disease, predominantly tumors in category T1c. The patterns of diagnosis and treatment of prostate cancer vary considerably in different parts of Sweden. The NPCR continues to be an important source for research, epidemiological surveillance of the incidence, diagnosis and treatment of prostate cancer.

- Background: A challenge in prostate cancer (PCa) management is identifying potentially lethal disease at diagnosis. Inflammation, focal prostatic atrophy, and prostatic intraepithelial neoplasia (PIN) are common in prostate tumor specimens, but it is not clear whether these lesions have prognostic significance. less thanbrgreater than less thanbrgreater thanMethods: We conducted a case-control study nested in a cohort of men diagnosed with stage T1a-b PCa through transurethral resection of the prostate in Sweden. Cases are men who died of PCa (n = 228). Controls are men who survived more than 10 years after PCa diagnosis without metastases (n = 387). Slides were assessed for Gleason grade, inflammation, PIN, and four subtypes of focal prostatic atrophy: simple atrophy (SA), postatrophic hyperplasia (PAH), simple atrophy with cyst formation, and partial atrophy. We estimated OR and 95% CI for odds of lethal PCa with multivariable logistic regression. less thanbrgreater than less thanbrgreater thanResults: Chronic inflammation and PIN were more frequently observed in tumors with PAH, but not SA. No specific type of atrophy or inflammation was significantly associated with lethal PCa overall, but there was a suggestion of a positive association for chronic inflammation. Independent of age, Gleason score, year of diagnosis, inflammation, and atrophy type, men with PIN were 89% more likely to die of PCa (95% CI: 1.04-3.42). less thanbrgreater than less thanbrgreater thanConclusion: Our data show that PIN, and perhaps presence of moderate or severe chronic inflammation, may have prognostic significance for PCa. less thanbrgreater than less thanbrgreater thanImpact: Lesions in tumor adjacent tissue, and not just the tumor itself, may aid in identification of clinically relevant disease.

- Objective To estimate the strength of change in haemoglobin (Hb) concentrations during 1 year of androgen-deprivation therapy (ADT) as a predictor of survival in hormone-naive patients with bone-metastatic (Stage M1b) prostate cancer. Patients and Methods The patients included in this study were taken from the randomised trial (number 5) carried out by the Scandinavian Prostate Cancer Group (SPCG), comparing parenteral oestrogen with total androgen blockade (TAB) in hormone-naive M1b prostate cancer. We identified 597 men where Hb measurements were made at enrolment, as well as at 3, 6 and 12 months of ADT. The time-dependent impact of Hb concentration changes on overall survival (OS) was analysed using multivariate Cox proportional hazards analysis. The 10-year OS according to increase/decrease in Hb concentration for the three treatment periods was demonstrated using Kaplan-Meier curves. Results Multivariate analysis of changes in Hb concentration between baseline and 3 months showed better survival in patients with a decrease in Hb concentration (hazard ratio [HR] 1.42, 95% confidence interval [CI] 1.11-1.80) compared to those with an increase, whilst there was no difference in survival associated with a change in Hb concentration between 3 and 6 months (HR 0.93, 95% CI 0.76-1.12). Contrary to the first 3 months, poorer survival was seen in patients with a decrease in Hb concentration between 6 and 12 months (HR 0.76, 95% CI 0.62-0.92) compared to those with an increase. Conclusions In a large cohort of Scandinavian men with hormone-nave M1b prostate cancer, an increase in Hb concentration between baseline and 3 months of ADT was associated with significantly poorer survival, whereas an increase between 6 and 12 months was associated with better survival. These findings provide new information about patterns of change in Hb concentrations during 12 months of ADT for M1b prostate cancer, and survival. Clinicians should be aware of the prognostic value of Hb concentration changes during ADT in M1b prostate cancer.

Tidskriftsartikel (refereegranskat)abstract
- OBJECTIVE: To evaluate the reliability of cause-of-death diagnoses among prostate cancer patients. MATERIAL AND METHODS: Information from death certificates obtained from the Swedish Death Register was compared with systematically reviewed medical records from the population-based Swedish Regional Prostate Cancer Register, South-East Region. In total, 5675 patients were included who had been diagnosed with prostate cancer between 1987 and 1999 and who had died before 1 January 2003. RESULTS: The proportion of prostate cancer cases classified as having died from prostate cancer was 3% higher in the official death certificates than in the reviewed records [0.03, 95% confidence interval (CI) 0.02 to 0.04]. Overall agreement between the official cause of death and the reviewed data was 86% (95% CI 85 to 87%). A higher accuracy was observed among men with localized disease (88%, 95% CI 87 to 89%), aged 60 years or younger at death (96%, 95% CI 93 to 100%), or who had undergone curative treatment (91%, 95% CI 88 to 95%). This study indicates a relatively high reliability of official cause-of-death statistics of prostate cancer patients in Sweden. CONCLUSION: Mortality data obtained from death certificates may be useful in the evaluation of large-scale prostate cancer intervention programmes, especially among younger patients with localized disease.

- Objective. To compare parenteral estrogen therapy in the form of high-dose polyestradiol phosphate (PEP, Estradurin®) with combined androgen deprivation (CAD) in the treatment of prostate cancer patients with skeletal metastases. The aim of the study was to compare anticancer efficacy and adverse events, especially cardiovascular events. Material and methods. In total, 910 eligible patients with T0-4, NX, M1, G1-3 prostate cancer with an Eastern Cooperative Oncology Group performance status of 0-2 were randomized to treatment with either PEP 240mg i.m. twice a month for 2months and thereafter monthly, or flutamide (Eulexin®) 250mg t.i.d. per os in combination with either triptorelin (Decapeptyl®) 3.75mg i.m. per month or on an optional basis bilateral orchidectomy. Results. At this final evaluation of the trial 855 of the 910 patients were dead. There was no difference between the treatment groups in terms of biochemical or clinical progression-free survival or in overall or disease-specific survival. There was no difference in cardiovascular mortality, but a significant increase in non-fatal cardiovascular events in the PEP arm (p<0.05) predominantly caused by an increase in ischemic heart and heart decompensation events. There were 18 grave skeletal events in the CAD group but none in the PEP group (p=0.001). Conclusions. PEP has an anticancer efficacy equal to CAD and does not increase cardiovascular mortality in metastasized patients, but carries a significant risk of non-fatal cardiovascular events, which should be balanced against the skeletal complications in the CAD group. It is feasible to use Estradurin in the primary or secondary endocrine treatment of metastasized patients without prominent cardiac risk factors and especially those with osteoporosis. © 2008 Taylor & Francis.

- Objective. This study aimed to evaluate prognostic risk factors for cardiovascular events during treatment of metastatic prostate cancer patients with high-dose parenteral polyoestradiol phosphate (PEP, Estradurin (R)) or combined androgen deprivation (CAD) with special emphasis on pretreatment cardiovascular disease. Material and methods. Nine-hundred and fifteen patients with T0-4, Nx, M1, G1-3, hormone- naive prostate cancer were randomized to treatment with PEP 240 mg i.m. twice a month for 2 months and thereafter monthly, or to flutamide (Eulexin (R)) 250 mg per os three times daily in combination with either triptorelin (Decapeptyl (R)) 3.75 mg i.m. per month or on an optional basis with bilateral orchidectomy. Pretreatment cardiovascular morbidity was recorded and cardiovascular events during treatment were assessed by an experienced cardiologist. A multivariate analysis was done using logistic regression. Results. There was a significant increase in cardiovascular events during treatment with PEP in patients with previous ischaemic heart disease (p = 0.008), ischaemic cerebral disease (p = 0.002), intermittent claudication (p = 0.031) and especially when the whole group of patients with pretreatment cardiovascular diseases was analysed together (p andlt; 0.001). In this group 33% of the patients had a cardiovascular event during PEP treatment. In the multivariate analysis PEP stood out as the most important risk factor for cardiac complications (p = 0.029). Even in the CAD group there was a significant increase in cardiovascular events in the group with all previous cardiovascular diseases taken together (p = 0.036). Conclusions. Patients with previous cardiovascular disease are at considerable risk of cardiovascular events during treatment with high-dose PEP and even during CAD therapy. Patients without pretreatment cardiovascular morbidity have a moderate cardiovascular risk during PEP treatment and could be considered for this treatment if the advantages of this therapy, e. g. avoidance of osteopenia and hot flushes and the low price, are given priority.

Tidskriftsartikel (refereegranskat)abstract
- Objective To describe characteristics and quality-of-life (QoL), and to define factors associated with long-term survival in a subgroup of patients with prostate cancer with M1b disease. Patients and Methods The study was based on 915 patients from a prospective randomised multicentre trial (No. 5) by the Scandinavian Prostate Cancer Group, comparing parenteral oestrogen with total androgen blockade. Long-term survival was defined as patients having an overall survival of >= 10 years, and logistic regression models were constructed to identity clinical predictors of survival. QoL during follow-up was assessed using the European Organisation for Research and Treatment of Cancer Quality-of-Life Questionnaire - C30 version 1 (EORTC-C30) ratings. Results In all, 40 (4.4%) of the 915 men survived for >10 years. Factors significantly associated with increased likelihood of surviving for >10 years in the univariate analyses were: absence of cancer-related pain; Eastern Cooperative Oncology Group (ECOG) performance status of <2; negligible analgesic consumption; T-category of 1-2; prostate-specific antigen (PSA) level of <231 mu g/L; and a Soloway score of 1. In the multivariate analyses, ECOG performance status of <2, PSA level of <231 mu g/L, and Soloway score of 1, were all independent predictors of long-term survival. All subscales of the EORTC-C30 were higher in this group than for patients with short survival, but slowly declined over the decade. Conclusion A subgroup of patients with prostate cancer with M1b disease and certain characteristics showed a positive long-term response to androgen-deprivation therapy with an acceptable QoL over a decade or more. Independent predictors of long-term survival were identified as ECOG performance status of <2, limited extent of bone metastases (Soloway score of 1), and a PSA level of <231 mu g/L at the time of enrolment.

- Objective: The aim of this study was to investigate the impact of bone metastasis on survival and quality of life (QoL) in men with hormone-naive prostate cancer. Materials and methods: The study included 900 patients from a randomized trial (No. 5) by the Scandinavian Prostate Cancer Group, comparing parenteral oestrogen with total androgen blockade. Extent of bone metastasis was categorized according to a modified Soloway score: score 1, n=319; score 2, n = 483; and score 3, n = 98 patients. The primary outcome measurements were mean differences in QoL and overall survival. Results: QoL rating scales showed a decrease with increasing extent of bone metastasis (p amp;lt; 0.001). The mean global health status decreased from 64.4 to 50.5 for Soloway score 1 and 3, respectively. Following adjustment for performance status, analgesic consumption, grade of malignancy, alkaline phosphatase, prostate-specific antigen, haemoglobin and global health status, Soloway score 2 and 3 had a 47% [hazard ratio (HR) 1.47, 95% confidence interval (CI) 1.21-1.80] and 78% (HR 1.78 95%, CI 1.32-2.42) increased mortality, respectively, compared to Soloway score 1. Independent predictive factors of mortality were assessed. Conclusions: Patient grouping based on three categories of extent of bone metastasis related to performance status, haemoglobin and global health status at presentation, as independent predictors of mortality, may provide improved accuracy of prognosis.

- OBJECTIVE To identify prognostic factors, and to estimate the long-term disease-specific and annual disease-specific mortality rates of low-risk prostate cancer patients from the early prostate-specific antigen (PSA) era. PATIENTS AND METHODS We studied data extracted from the Southeast Region Prostate Cancer Register in Sweden, on 1300 patients with clinically localized low-risk tumors, T1-2, PSA level amp;lt;= 10 mu g/L and Gleason scores 2-6 or World Health Organization Grade 1, diagnosed 1992-2003. The Cox multivariate regression model was used to evaluate factors predicting survival. Prostate cancer death rates per 1000 person-years were estimated for 4 consecutive follow-up time periods: 0-5, 5-10, 10-15, and 15+ years after diagnosis. RESULTS During the follow-up of overall survivors (mean 10.6 years; maximum 21.8 years), 93 patients (7%) died of prostate cancer. Cancer-specific survival was 0.98 (95% confidence interval [CI] 0.97-0.99), 0.95 (95% CI 0.93-0.96), 0.89 (95% CI 0.86-0.91), and 0.84 (95% CI 0.80-0.88), 5, 10, 15, and 20 years after diagnosis. The 5-year increases in cancer-specific mortality were statistically significant (P amp;lt;. 001). Patients with PSA amp;gt;= 4 mu g/L managed initially with watchful waiting and those aged 70 years or older had a significantly higher risk of dying from their prostate cancer. CONCLUSION The long-term disease-specific mortality of low-risk localized prostate cancer is low, but the annual mortality rate from prostate cancer gradually increases. This indicates that some tumors slowly develop into lethal cancer, particularly in patients 70 years or older with a PSA level amp;gt;= 4 mu g/L. (C) 2016 Elsevier Inc.
