- 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.

- 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.

Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- IntroductionProstate cancer (PCa) is the most common cancer among men in Sweden. The clinical course varies considerably, which makes it difficult to predict the prognosis in the individual case. In order to explore the early as well as the late course of the disease, large study groups and population-based cohorts are necessary.AimsTo explore factors that influence the long-term outcome of men with low-risk tumours in a population-based register, to predict the long-term course, and to assess the mortality rate for men with prostate cancer (Paper I)To analyse long-term outcome and to investigate factors associated with long-term survival in patients with metastases to the skeleton (Paper II)To analyse early androgen deprivation treatment (ADT) failure and to define clinical predictors associated with short survival due to early ADT failure in prostate cancer patients with bone metastases (Paper III)To analyse the prognostic significance of the extent of bone metastases in relation to other pretreatment variables in prostate cancer patients, and to explore the impact of bone metastases on quality-of-life (Paper IV)Material and methodsThe study groups were assembled from The South East Region Prostate Cancer Register (SERPCR), and The Scandinavian Prostate Cancer Group (SPCG) Trial No. 5. In the first study, prognostic factors and long-term disease-specific mortality rates of low-risk prostate cancer patients from the early PSA era were analysed. In the second study, patient-related factors, quality-of-life (QoL) and long-term survival in 915 PCa patients with bone metastases (M1b) under ADT, were analysed. In Study III factors predicting primary failure to respond to ADT were identified. Study IV explored the impact of the extent of bone metastases on survival and QoL for these men.Result and conclusionsThe long-term disease-specific mortality of low-risk localised PCa is low, but the annual mortality rate gradually increases. This indicates that some tumours slowly develop into lethal cancer, particularly in men 70 years or older and with a PSA level ≥ 4 μg/L. From the SPCG Trial No. 5, a subgroup of patients with M1b disease and favourable set of predictive factors survived more than 10 years under ADT with an acceptable QoL. Independent predictors of long-term survival were identified as performance status (PS) < 2, limited extent of bone metastases, and a PSA level < 231 μg/L at the time of enrolment in the trial. However, four independent clinical predictors of early ADT failure could be defined. Men exhibiting these features should be considered for an alternative treatment. Patient grouping based on three categories of extent of bone metastases related to PS, haemoglobin, and QoL 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.

Tidskriftsartikel (refereegranskat)abstract
- Background: There is insufficient information regarding the benefit of treatment with curative intent for men with localised poorly differentiated prostate cancer (PCa). Objective: To evaluate relative survival in men with potentially curable PCa in relation to Gleason score (GS) and treatment as practiced in the community at large. Design, setting, and participants: A population-based study including all men with localised PCa registered in Sweden's National Prostate Cancer Register. Interventions: Hormonal therapy, watchful waiting, and treatment with curative intent. Measurements: The ratio of observed deaths to expected deaths, determined from survival in the general male population of the same age, was assessed using Poisson regression analysis, with GS and treatment as covariates. Interaction between GS and treatment was tested in a multivariate Cox proportional hazard analysis. Results and limitations: A total of 31 903 men with potentially curable tumour (T1-T3, N0/NX, M0/MX, age < 75 yr, and prostate-specific antigen [PSA] < 20 ng/ml) were identified. GS was recorded for 28 454 of these men. Some 19 606 men (60.8%) were treated with curative intent, and 12 645 men (39.2%) were given either hormonal treatment or expectant management. The ratios between observed and expected survival gradually increased for men with GS 10, with GS to 3.3 for men treated conservatively and to 1.4 for men treated with curative intent. There was a significant interaction between GS and treatment, with a relatively greater benefit from treatment with curative intent for men with high-grade tumours. The results have to be interpreted with some caution, as there was no randomisation between the treatment groups. Conclusions: Survival for men with well-differentiated tumours is close to that of the general population, regardless of treatment, but the outcome is dismal for men with poorly differentiated tumours, whichever treatment is applied. Nevertheless, men with poorly differentiated tumours benefit more from curative treatment than do men with well-differentiated tumours.

- Objectives: To assess the value of prostate-specific antigen (PSA) kinetics in predicting survival and relate this to the baseline variables in men with metastatic hormone-refractory prostate cancer (HRPC). Methods: The data from 417 men with HRPC were included in a logistic regression model that included hemoglobin, PSA, alkaline phosphatase, Soloway score, and performance status pain analgesic score at baseline. The posttreatment variables included the PSA level halving time after the start of treatment, PSA level at nadir, interval to nadir, PSA velocity (PSAV), PSA doubling time after reaching a nadir, patient age, and treatment. These variables were added to the baseline model, forming new logistic regression models that were tested for net reclassification improvement. Results: The area under the receiver operating characteristics curve for the baseline model was 0.67. Of all variables related to PSA kinetics, the PSAV was the best predictor. The addition of PSAV to the baseline model increased the area under the receiver operating characteristics curve to 0.81. Only a moderate increase in the area under the receiver operating characteristics curve (0.83) was achieved by combining the baseline model in a multivariate model with PSAV, PSA doubling time, interval to nadir, and patient age at diagnosis of HRPC. Conclusions: The PSAV alone gave a better prediction of survival value than all other PSA kinetics variables. By combining PSAV with the variables available at baseline, a better ground for treatment decision-making in men with HRPC can be achieved.
