  • Gonadotropin-releasing Hormone Agonists, Orchiectomy, and Risk of Cardiovascular Disease Semi-ecologic, Nationwide, Population-based Study
  • 2017
  • Ingår i: European Urology. - 0302-2838 .- 1873-7560. ; 72:6, s. 920-928
  • Tidskriftsartikel (refereegranskat)abstract
    • BACKGROUND: In observational studies, men with prostate cancer treated with gonadotropin-releasing hormone (GnRH) agonists had a higher risk of cardiovascular disease (CVD) compared to men who had undergone orchiectomy. However, selection bias may have influenced the difference in risk.OBJECTIVE: To investigate the association of type of androgen deprivation therapy (ADT) with risk of CVD while minimising selection bias.DESIGN, SETTING, AND PARTICIPANTS: Semi-ecologic study of 6556 men who received GnRH agonists and 3330 men who underwent orchiectomy as primary treatment during 1992-1999 in the Prostate Cancer Database Sweden 3.0.OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS: We measured the proportion of men who received GnRH agonists as primary treatment in 580 experimental units defined by healthcare provider, diagnostic time period, and age at diagnosis. Incident or fatal CVD events in units with high and units with low use of GnRH agonists were compared. Net and crude probabilities were also analysed.RESULTS AND LIMITATIONS: The risk of CVD was similar between units with the highest and units with the lowest proportion of GnRH agonist use (relative risk 1.01, 95% confidence interval [CI] 0.93-1.11). Accordingly, there was no difference in the net probability of CVD after GnRH agonist compared to orchiectomy (hazard ratio 1.02, 95% CI 0.96-1.09). The 10-yr crude probability of CVD was 0.56 (95% CI 0.55-0.57) for men on GnRH agonists and 0.52 (95% CI 0.50-0.54) for men treated with orchiectomy. The main limitation was the nonrandom allocation to treatment, with younger men with lower comorbidity and less advanced cancer more likely to receive GnRH agonists.CONCLUSION: Our data do not support previous observations that GnRH agonists increase the risk of CVD in comparison to orchiectomy.PATIENT SUMMARY: We found a similar risk of cardiovascular disease between medical and surgical treatment as androgen deprivation therapy for prostate cancer.

  • Functional Outcomes and Quality of Life After Radical Prostatectomy Only Versus a Combination of Prostatectomy with Radiation and Hormonal Therapy
  • 2017
  • Ingår i: European Urology. - 0302-2838 .- 1873-7560. ; 71:3, s. 330-336
  • Tidskriftsartikel (refereegranskat)abstract
    • Background: While the optimal use and timing of secondary therapy after radical prostatectomy (RP) remain controversial, there are limited data on patient-reported outcomes following multimodal therapy.Objective: To assess the impact of additional radiation therapy (RT) and/or androgen deprivation therapy (ADT) on urinary continence, potency, and quality of life (QoL) after RP.Design, setting, and participants: Among 13 150 men who underwent RP from 1992 to 2013, 905 received RP + RT, 407 RP + ADT and 688 RP + RT + ADT.Outcome measurements and statistical analyses: Urinary function, sexual function, and overall QoL were evaluated annually using self-administered validated questionnaires. Propensity score-matched and bootstrap analyses were performed, and the distributions for all functional outcomes were analyzed as a function of time after RP.Results and limitations: Patients who received RP + RT had a 4% higher overall incontinence rate 3 yr after surgery, and 1% higher rate for severe incontinence (> 3 pads/24 h) compared to matched RP-only patients. ADT further increased the overall and severe incontinence rates by 4% and 3%, respectively, compared to matched RP + RT patients. RP + RT was associated with an 18% lower rate of potency compared to RP alone, while RP + RT + ADT was associated with a further 17% reduction compared to RP + RT. Additional RT reduced QoL by 10% and additional ADT by a further 12% compared to RP only and RP + RT, respectively. The timing of RT after RP had no influence on continence, but adjuvant compared to salvage RT was associated with significantly lower potency (37% vs 45%), but higher QoL (60% vs 56%). Limitations of our study include the observational study design and potential for selection bias in the treatments received.Conclusions: Secondary RT and ADT after RP have an additive negative influence on urinary function, potency, and QoL. Patients with high-risk disease should be counseled before RP on the potential net impairment of functional outcomes due to multimodal treatment.Patient summary: Men with high-risk disease choosing surgery upfront should be counseled on the potential need for additional radiation and or androgen deprivation, and the potential net impairment of functional outcomes arising from multimodal treatment.

  • Androgen Deprivation Therapies and Changes in Comorbidity : A Comparison of Gonadotropin-releasing Hormone Agonists and Antiandrogen Monotherapy as Primary Therapy in Men with High-risk Prostate Cancer
  • 2019
  • Ingår i: European Urology. - ELSEVIER SCIENCE BV. - 0302-2838 .- 1873-7560. ; 75:4, s. 676-683
  • Tidskriftsartikel (refereegranskat)abstract
    • Background: Some studies suggest that gonadotropin-releasing hormone (GnRH) agonists are associated with higher risk of adverse events than antiandrogens (AAs) monotherapy. However, it has been unclear whether this is due to indication bias.Objective: To investigate rates of change in comorbidity for men on GnRH agonists versus AA monotherapy in a population-based register study.Design, setting, and participants: Men with advanced nonmetastatic prostate cancer (PCa) who received primary AA (n = 2078) or GnRH agonists (n = 4878) and age- and area-matched PCa-free men were selected from Prostate Cancer Database Sweden 3.0. Increases in comorbidity were measured using the Charlson Comorbidity Index (CCI), from 5 yr before through to 5 yr after starting androgen deprivation therapy (ADT).Outcome measures and statistical methods: Multivariable linear regression was used to determine differences in excess rate of CCI change before and after ADT initiation. Risk of any incremental change in CCI following ADT was assessed using multivariable Cox regression analyses.Results and limitations: Men on GnRH agonists experienced a greater difference in excess rate of CCI change after starting ADT than men on AA monotherapy (5.6% per yr, p < 0.001). Risk of any new CCI change after ADT was greater for GnRH agonists than for AA (hazard ratio, 1.32; 95% confidence interval, 1.20-144).Conclusions: Impact on comorbidity was lower for men on AA monotherapy than for men on GnRH agonists. Our results should be confirmed through randomised trials of effectiveness and adverse effects, comparing AA monotherapy and GnRH agonists in men with advanced nonmetastatic PCa who are unsuitable for curative treatment.Patient summary: Hormone therapies for advanced prostate cancer can increase the risk of other diseases (eg, heart disease, diabetes). This study compared two common forms of hormone therapy and found that the risk of another serious disease was higher for those on gonadotropin-releasing hormone agonists than for those on antiandrogen monotherapy.

  • Long-term Distress After Radical Prostatectomy Versus Watchful Waiting in Prostate Cancer : A Longitudinal Study from the Scandinavian Prostate Cancer Group-4 Randomized Clinical Trial
  • 2013
  • Ingår i: European Urology. - 0302-2838 .- 1873-7560. ; 64:6, s. 920-928
  • Tidskriftsartikel (refereegranskat)abstract
    • BACKGROUND:Studies enumerating the dynamics of physical and emotional symptoms following prostate cancer (PCa) treatment are needed to guide therapeutic strategy. Yet, overcoming patient selection forces is a formidable challenge for observational studies comparing treatment groups.OBJECTIVE:To compare patterns of symptom burden and distress in men with localized PCa randomized to radical prostatectomy (RP) or watchful waiting (WW) and followed up longitudinally.DESIGN, SETTING, AND PARTICIPANTS:The three largest, Swedish, randomization centers for the Scandinavian Prostate Cancer Group-4 trial conducted a longitudinal study to assess symptoms and distress from several psychological and physical domains by mailed questionnaire every 6 mo for 2 yr and then yearly through 8 yr of follow-up.INTERVENTION:RP compared with WW.OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS:A questionnaire was mailed at baseline and then repeatedly during follow-up with questions concerning physical and mental symptoms. Each analysis of quality of life was based on a dichotomization of the outcome (yes vs no) studied in a binomial response, generalized linear mixed model.RESULTS AND LIMITATIONS:Of 347 randomized men, 272 completed at least five questionnaires during an 8-yr follow-up period. Almost all men reported that PCa negatively influenced daily activities and relationships. Health-related distress, worry, feeling low, and insomnia were consistently reported by approximately 30-40% in both groups. Men in the RP group consistently reported more leakage, impaired erection and libido, and fewer obstructive voiding symptoms. For men in the WW group, distress related to erectile symptoms increased gradually over time. Symptom burden and distress at baseline was predictive of long-term outlook.CONCLUSIONS:Cancer negatively influenced daily activities among almost all men in both treatment groups; health-related distress was common. Trade-offs exist between physiologic symptoms, highlighting the importance of tailored treatment decision-making. Men who are likely to experience profound long-term distress can be identified early in disease management.

  • The Value of an Extensive Transrectal Repeat Biopsy with Anterior Sampling in Men on Active Surveillance for Low-risk Prostate Cancer : A Comparison from the Randomised Study of Active Monitoring in Sweden (SAMS)
  • 2019
  • Ingår i: European Urology. - ELSEVIER. - 0302-2838 .- 1873-7560. ; 76:4, s. 461-466
  • Tidskriftsartikel (refereegranskat)abstract
    • Background: A systematic repeat biopsy is recommended for men starting on active surveillance for prostate cancer, but the optimal number and distribution of cores are unknown. Objective: To evaluate an extensive repeat transrectal biopsy with anterior sampling in men starting on active surveillance. Design, setting, and participants: Randomised multicentre trial. From 2012 to 2016, 340 Swedish men, aged 40-75 yr, with recently diagnosed low-volume Gleason grade group 1 prostate cancer were included. Intervention: Either an extensive transrectal biopsy with anterior sampling (median 19 cores) or a standard transrectal biopsy (median 12 cores). Outcome measurements and statistical analysis: Primary outcome measure: Gleason grade group >= 2 cancer. Secondary outcomes: Cancer in anteriorly directed biopsy cores and postbiopsy infection. Nonparametric statistical tests were applied. Results and limitations: Gleason grade group >= 2 cancer was detected in 16% of 156 men who had an extensive biopsy and in 10% of 164 men who had a standard biopsy, a 5.7% difference (95% confidence interval [CI]-0.2% to 13%, p = 0.09). There was a strong linear association between prostate-specific antigen (PSA) density and cancer in the anteriorly directed biopsy cores. The odds ratios for cancer in the anteriorly directed cores were for any cancer 2.2 (95% CI 1.3-3.9, p = 0.004) and for Gleason grade group >= 2 cancer 2.3 (95% CI 1.2-4.4, p = 0.015) per 0.1-ng/ml/cm(3) increments. Postbiopsy infections were equally common in the two groups. A limitation is that magnetic resonance imaging was not used. Conclusions: The trial did not support general use of the extensive transrectal repeat biopsy template, but cancer in the anteriorly directed cores was common, particularly in men with high PSA density. The higher the PSA density, the stronger the reason to include anterior sampling at a systematic repeat biopsy. Patient summary: This trial compared two different templates for transrectal prostate biopsy in men starting on active surveillance for low-risk prostate cancer. Cancer was often found in the front part of the prostate, which is not sampled on a standard prostate biopsy. (C) 2019 European Association of Urology. Published by Elsevier B.V. All rights reserved.

  • Prognostic Impact of a 12-gene Progression Score in Non-muscle-invasive Bladder Cancer : A Prospective Multicentre Validation Study
  • 2017
  • Ingår i: European Urology. - 0302-2838 .- 1873-7560. ; 72:3, s. 461-469
  • Tidskriftsartikel (refereegranskat)abstract
    • Background: Progression of non-muscle-invasive bladder cancer (NMIBC) to muscle-invasive bladder cancer (MIBC) is life-threatening and cannot be accurately predicted using clinical and pathological risk factors. Biomarkers for stratifying patients to treatment and surveillance are greatly needed. Objective: To validate a previously developed 12-gene progression score to predict progression to MIBC in a large, multicentre, prospective study. Design, setting, and participants: We enrolled 1224 patients in ten European centres between 2008 and 2012. A total of 750 patients (851 tumours) fulfilled the inclusion and sample quality criteria for testing. Patients were followed for an average of 28 mo (range 0-76). A 12-gene real-time qualitative polymerase chain reaction assay was performed for all tumours and progression scores were calculated using a predefined formula and cut-off values. Outcome measurements and statistical analysis: We measured progression to MIBC using Cox regression analysis and log-rank tests for comparing survival distributions. Results and limitations: The progression score was significantly (p < 0.001) associated with age, stage, grade, carcinoma in situ, bacillus Calmette-Guerin treatment, European Organisation for Research and Treatment of Cancer risk score, and disease progression. Univariate Cox regression analysis showed that patients molecularly classified as high risk experienced more frequent disease progression (hazard ratio 5.08, 95% confidence interval 2.2-11.6; p < 0.001). Multivariable Cox regression models showed that the progression score added independent prognostic information beyond clinical and histopathological risk factors (p < 0.001), with an increase in concordance statistic from 0.82 to 0.86. The progression score showed high correlation (R-2 = 0.85) between paired fresh-frozen and formalin-fixed paraffin-embedded tumour specimens, supporting translation potential in the standard clinical setting. A limitation was the relatively low progression rate (5%, 37/ 750 patients). Conclusions: The 12-gene progression score had independent prognostic power beyond clinical and histopathological risk factors, and may help in stratifying NMIBC patients to optimise treatment and follow-up regimens. Patient summary: Clinical use of a 12-gene molecular test for disease aggressiveness may help in stratifying patients with non-muscle-invasive bladder cancer to optimal treatment regimens.
