- 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.

- Objective To assess 90-day postoperative mortality after robot-assisted laparoscopic radical prostatectomy (RARP) and retropubic radical prostatectomy (RRP) using nationwide population-based registry data. Patients and Methods We conducted a cohort study using the National Prostate Cancer Register of Sweden, including 22 344 men with localized prostate cancer of clinical stage T1-T3, whose prostate-specific antigen levels were <50 mu g/mL and who had undergone primary radical prostatectomy in the period 1998-2012. Vital status was ascertained through the Total Population Register. The rates for 90-day postoperative mortality were analysed using logistic regression analysis, and comparisons of 90-day mortality with the background population were made using standardized mortality ratios (SMRs). Results Of the 14 820 men who underwent RRP, 29 (0.20%) died, and of the 7 524 men who underwent RARP, 10 (0.13%) died. Mortality in the cohort during the 90-day postoperative period was lower than in an age-matched background population: SMR 0.57 (95% confidence interval [CI] 0.39-0.75). There was no statistically significant difference in 90-day mortality according to surgical method: RARP vs RRP odds ratio (OR) 1.14; 95% CI 0.46-2.81. Postoperative 90-day mortality decreased over time: 2008-2012 vs 1998-2007 OR 0.44; 95% CI 0.21-0.95, mainly because of lower mortality after RARP. Conclusion The 90-day postoperative mortality rates were low after RARP and RRP and there was no statistically significant difference between the methods. Given the long life expectancy among men with low-and intermediate-risk prostate cancer, very low postoperative mortality is a prerequisite for RP, which was fulfilled by both RRP and RARP. The selection of healthy men for RP is highlighted by the lower 90-day mortality after RP compared with the background population.

- 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.

- Objective To investigate how much Gleason pattern 3 cancer prostate biopsy specimens may contain without an increased risk of undetected more aggressive cancer, compared with the risk for cancers fulfilling the National Comprehensive Cancer Network (NCCN) criteria for very low-risk prostate cancer. Patients and Methods We identified 1286 men aged <70 years in the National Prostate Cancer Register of Sweden who underwent primary radical prostatectomy (RP) for stage T1c or T2 prostate cancer with Gleason pattern <= 3 only, prostate-specific antigen (PSA) level of <10 ng/mL and a PSA density of <0.15 ng/mL/mL. The association between the extent of cancer in the biopsies (the number and proportion of positive cores and the total cancer length in the cores in millimetres) and the likelihood of Gleason pattern 4-5 in the RP specimen was analysed with logistic regression. Results In all, 438 (34%) of the 1286 men had Gleason pattern 4-5 in the RP specimen. Increasing number and proportion of positive biopsy cores, as well as increasing biopsy cancer length were both significantly associated with increased risk of upgrading at RP in univariable analysis, but in multivariable analysis only biopsy cancer length remained significant. The 684 men with stage T1c and < 8 mm cancer had similar risk of upgrading regardless of whether the number of positive biopsy cores was 1-2 or 3-4 (28% vs 27% risk); upgrading was more common among the remaining men (40%, P < 0.01). Conclusions Men aged < 70 years with stage T1c prostate cancer and 3-4 biopsy cores with Gleason pattern 3 are not more likely to have undetected Gleason pattern 4-5 cancer than men with 1-2 cores with cancer, provided that the total biopsy cancer length is < 8 mm. We propose that the definition of very low-risk prostate cancer is widened accordingly.

- OBJECTIVE: To evaluate long-term urinary, sexual and bowel functional outcomes after prostate cancer treatment at a median follow-up of 12 years (IQR 11-13).PATIENTS AND METHODS: In this nationwide, population-based study, we identified from the National Prostate Cancer Register, Sweden, 6,003 men diagnosed with localized prostate cancer (clinical local stage T1-2, any Gleason score, prostate specific antigen < 20 ng/mL, NX or N0, MX or M0) between 1997 and 2002 who were ≤70 years at diagnosis. 1,000 prostate cancer-free controls were selected, matched for age and county of residence. Functional outcomes were evaluated with a validated self-reported questionnaire.RESULTS: Responses were obtained from 3,937/6,003 cases (66%) and 459/1,000 (46%) controls. Twelve years post diagnosis, at a median age of 75 years, the proportion of cases with adverse symptoms was 87% for erectile dysfunction or sexually inactive, 20% for urinary incontinence and 14% for bowel disturbances. The corresponding proportions for controls were 62%, 6% and 7%, respectively. Men with prostate cancer, except those on surveillance, had an increased risk of erectile dysfunction, compared to control men. Radical prostatectomy was associated with increased risk of urinary incontinence (odds ratio; OR 2.29 [95% CI 1.83-2.86] and radiotherapy increased the risk of bowel dysfunction (OR 2.46 [95% CI 1.73-3.49]) compared to control men. Multi-modal treatment, in particular including androgen deprivation therapy (ADT), was associated with the highest risk of adverse effects; for instance radical prostatectomy followed by radiotherapy and ADT was associated with an OR of 3.74 [95 CI 1.76-7.95] for erectile dysfunction and OR 3.22 [95% CI 1.93-5.37] for urinary incontinence.CONCLUSION: The proportion of men who suffer long-term impact on functional outcomes after prostate cancer treatment was substantial.

- Objectives To investigate how well the Gleason score in diagnostic needle biopsies predicted the Gleason score in a subsequent radical prostatectomy (RP) specimen before and after the 2005 International Society of Urological Pathology (ISUP) revision of Gleason grading, and if the recently proposed ISUP grades 1-5 (corresponding to Gleason scores 6, 3 + 4, 4 + 3, 8 and 9-10) better predict the RP grade. Patients and Methods All prostate cancers diagnosed in Sweden are reported to the National Prostate Cancer Register (NPCR). We analysed the Gleason scores and ISUP grades from the diagnostic biopsies and the RP specimens in 15 598 men in the NPCR who: were diagnosed between 2000 and 2012 with clinical stage T1-2 M0/X prostate cancer on needle biopsy; were aged <= 70 years; had serum PSA concentration of < 20 ng/mL; and underwent a RP < 6 months after diagnosis as their primary treatment. Results Prediction of RP Gleason score increased from 55 to 68% between 2000 and 2012. Most of the increase occurred before 2005 (nine percentage points; P < 0.001); however, when adjusting for Gleason score and year of diagnosis in a multivariable analysis, the prediction of RP Gleason score decreased over time (odds ratio [OR] 0.98; P < 0.002). A change in the ISUP grades would have led to a decreasing agreement between biopsy and RP grades over time, from 68% in 2000 to 57% in 2012, with an OR of 0.95 in multivariable analysis (P < 0.001). Conclusion Agreement between biopsy and RP Gleason score improved from 2000 to 2012, with most of the improvement occurring before the 2005 ISUP grading revision. Had ISUP grades been used instead of Gleason score, the agreement between biopsy and RP grade would have decreased, probably because of its separation of Gleason score 7 into ISUP grades 2 and 3 (Gleason score 3 + 4 vs 4 + 3).

- BACKGROUND: Men have a higher risk of death from COVID-19 than women and androgens facilitate entrance of the SARS-CoV-2 virus into respiratory epithelial cells. Thus, androgen deprivation therapy may reduce infection rates and improve outcomes for COVID-19. In the spring of 2020, Sweden was highly affected by COVID-19. The aim was to estimate the impact of androgen deprivation therapy on mortality from COVID-19 in men with prevalent prostate cancer by comparing all-cause mortality in the spring of 2020 to that in previous years.PATIENTS AND METHODS: Using the Prostate Cancer data Base Sweden all men with prostate cancer on March 1 each year in 2015-2020 were followed until June 30 the same year. Exposure to androgen deprivation therapy was ascertained from filled prescriptions for bicalutamide monotherapy, gonadotropin-releasing hormone agonists (GnRH), or bilateral orchidectomy.RESULTS: A total of 9,822 men died in March-June in the years 2015-2020, of whom 5,034 men were on androgen deprivation therapy. There was an excess mortality in 2020 vs previous years in all men. The crude relative mortality rate ratio for 2020 vs 2015-2019 was 0.93 (95% confidence interval (CI) 0.83 to 1.04) in men on GnRH, and 0.90 (95% CI 0.78 to 1.05) in men on bicalutamide monotherapy. After multivariable adjustment these ratios were attenuated to 1.00 (95% CI 0.89 to 1.12) and 0.97 (95% CI 0.84 to 1.12), respectively. When restricting the analysis to the regions with the highest incidence of COVID-19 or to the time period between 2 April to 10 June when mortality in 2020 was increased >30% compared to previous years, the results were similar to the main analysis.CONCLUSIONS: In this large national population-based cohort of men with prevalent prostate cancer, there was no clear evidence in support for an effect of androgen deprivation therapy on COVID-19 mortality.

- BACKGROUND: Androgens facilitate entrance of the severe acute respiratory syndrome coronavirus 2 into respiratory epithelial cells, and male sex is associated with a higher risk of death from corona virus disease (COVID-19). Androgen deprivation therapy (ADT) could possibly improve COVID-19 outcomes.METHODS: In a case-control study nested in the Prostate Cancer data Base Sweden (PCBaSe) RAPID 2019, we evaluated the association between ADT and COVID-19 as registered cause of death in men with prostate cancer. Each case was matched to 50 controls by region. We used conditional logistic regression to adjust for confounders and also evaluated potential impact of residual confounding.RESULTS: We identified 474 men who died from COVID-19 in March-December 2020. In crude analyses, ADT exposure was associated with an increased risk of COVID-19 death (odds ratio [OR] 5.05, 95% CI: 4.18-6.10); however, the OR was substantially attenuated after adjustment for age, comorbidity, prostate cancer characteristics at diagnosis, recent healthcare use, and indicators of advanced cancer (adjusted OR 1.25, 95% CI: 0.95-1.65). If adjustment has accounted for at least 85% of confounding, then the true effect could be no more than a 5% reduction of the odds for COVID-19 death.CONCLUSIONS: The increased mortality from COVID-19 in men with prostate cancer treated with ADT was mainly related to high age, comorbidity, and more advanced prostate cancer. There was no evidence to support the hypothesis that ADT is associated with improved COVID-19 outcomes.

Tidskriftsartikel (refereegranskat)abstract
- Androgen deprivation therapy (ADT) has been hypothesized to protect against COVID-19, but previous observational studies of men with prostate cancer on ADT have been inconsistent regarding mortality risk from coronavirus disease 2019 (COVID-19). Using data from the Prostate Cancer data Base Sweden (PCBaSe), we identified a cohort of 114 547 men with prevalent prostate cancer on the start of follow-up in February 2020, and followed them until 16 December 2020 to evaluate the association between ADT and time to test positive for COVID-19. Among men testing positive for COVID-19, we used regression analyses to estimate the association between ADT and risk of COVID-19-related hospital admission/death from any cause within 30 days of the positive test. In total, 1695 men with prostate cancer tested positive for COVID-19. In crude analyses, exposure to ADT was associated with a 3-fold increased risk of both testing positive for COVID-19 infection and subsequent hospital admission/death. Adjustment for age, comorbidity and prostate cancer risk category substantially attenuated the associations: HR 1.3 (95% CI: 1.1-1.5) for testing positive for COVID-19, and OR 1.4 (95% CI: 1.0-1.9) for risk of subsequent hospital admission/death. In conclusion, although these results suggest increased risks of a positive COVID-19 test, and COVID-19-related hospital admission/death in men on ADT, these findings are likely explained by confounding by old age, cancer-associated morbidity and other comorbidities being more prevalent in men on ADT, rather than a direct effect of the therapy.
