- OBJECTIVE: To investigate the cause-specific mortality in the postoperative period after radical prostatectomy (RP) for prostate cancer (PCa).METHODS: In the National Prostate Cancer Register of Sweden (NPCR), we identified all men who died within 90 days after RP performed 1998-2018 and we assessed cause of death in a chart review. We compared the adjudications of death from our medical record review with those in in the Swedish Cause of Death Registry (CDR).RESULTS: Out of 44 635, 58 (0.13%) men who had undergone RP from 1998 through 2018 died within 90 days after RP. Per medical record review the most common causes of death were cardiac disease (30%) and venous thromboembolic events (VTE; 21%). No men died of metastatic PCa as was first indicated in the CDR. After robot-assisted RP (RARP) or open retropubic RP (RRP), the postoperative mortality was 0.09% (19/21 520) and 0.19% (37/19 635), respectively. The effect off modality was confounded mainly by year of surgery, age at surgery, Charlson Comorbidity Index score and the concomitant pelvic lymph node dissection.CONCLUSION: The validated absolute 90-day mortality after RP was 1.3/1000 during the 21-year study period. Cardiovascular diseases were the most common causes of death after RP. Our validation of the CDR refuted the occurrence of postoperative deaths from metastatic PCa. There were differences in rates and type of mortality between RRP and RARP, but the RARP cohort was more recent than the RRP cohort, which likely explain the differences.

- Objectives: To predict castration-resistant prostate cancer (CRPC) and prostate cancer (Pca) death by use of clinical variables at Pca diagnosis and PSA levels after start of gonadotropin-releasing hormone agonists (GnRH) in men with non-metastatic castration sensitive prostate cancer (nmCSPC).Materials and Methods: PSA values for 1603 men with nmCSPC in the National Prostate Cancer Register of Sweden who received GnRH as primary treatment were retrieved from Uppsala-Örebro PSA Cohort and Stockholm PSA and Biopsy Register. All men had measured PSA before (pre-GnRH PSA) and 3–6 months after (post-GnRH PSA) date of start of GnRH. Unadjusted and adjusted Cox models were used to predict CRPC by PSA levels. PSA levels and ISUP grade were used to construct a risk score to stratify men by tertiles according to risk of CRPC and Pca death.Results: 788 (49%) men reached CRPC and 456 (28%) died of Pca during follow-up. Post-GnRH PSA predicted CRPC regardless of pre-GnRH PSA. CRPC risk increased with higher post-GnRH PSA, HR 4.7 (95% CI: 3.4–6.7) for PSA > 16 ng/mL vs 0–0.25 ng/mL and with ISUP grade, HR 3.7 (95%: 2.5–5.4) for ISUP 5 vs ISUP 1. Risk of Pca death in men above top vs bellow bottom tertile of post-GnRH PSA and ISUP grade was HR 4.1 (95% CI: 3.0–5.5).Conclusion: A risk score based on post-GnRH PSA and ISUP grade could be used for early identification of a target group for future clinical trials on additional therapy to GnRH.

- Objectives The objective of this study is to find clinical variables that predict the prognosis for men with castration-resistant prostate cancer (CRPC) in a Swedish real-life CRPC cohort, including a risk group classification to clarify the risk of succumbing to prostate cancer. This is a natural history cohort representing the premodern drug era before the introduction of novel hormonal drug therapies.Methods PSA tests from the clinical chemistry laboratories serving health care in six regions of Sweden were retrieved and cross-linked to the National Prostate Cancer Registry (NPCR) to identify men with a prostate cancer diagnosis. Through further cross-linking with data sources at the Swedish Board of Health and Welfare, we retrieved other relevant information such as prescribed drugs, hospitalizations, and cause of death. Men entered the CRPC cohort at the first date of doubling of their PSA nadir value with the last value being >2 ng/ml, or an absolute increase of >5 ng/ml or more, whilst on 3 months of medical castration or if they had been surgically castrated (n = 4098). By combining the two variables with the largest C-statistics, “PSA at time of CRPC” and “PSA doubling time,” a risk group classification was created.Rsults PSA-DT and PSA at date of CRPC are the strongest variables associated with PC specific survival. At the end of follow-up, the proportion of men who died due to PC was 57%, 71%, 81%, 86%, and 89% for risk categories one through five, respectively. The median overall survival in our cohort of men with CRPC was 1.86 years (95% CI: 1.79–1.97).Conclusion For a man with castration-resistant prostate cancer, there is a high probability that this will be the main cause contributing to his death. However, there is a significant difference in mortality that varies in relation to tumor burden assessed as PSA doubling time and PSA at time of CRCP. This information could be used in a clinical setting when deciding when to treat more or less aggressively once entering the CRPC phase of the disease.

- Background: Little is known about disease trajectories for men with castration -resistant prostate cancer (CRPC).Objective: To create a state transition model that estimates time spent in the CRPC state and its outcomes.Design, setting, and participants: The model was generated using population -based prostate-specific antigen data from 40% of the Swedish male population, which were linked to nationwide population-based databases. We compared the observed and predicted cumulative incidence of transitions to and from the CRPC state.Outcome measurements and statistical analysis: We measured time spent in the CRPC state and the proportion of men who died of prostate cancer during follow-up by CRPC risk category.Results and limitations: Time spent in the CRPC state varied from 1.1 yr for the highest risk category to 3.9 yr for the lowest risk category. The proportion of men who died from prostate cancer within 10 yr ranged from 93% for the highest risk category to 54% for the lowest. There was good agreement between the model estimates and observed data.Conclusions: There is large variation in the time spent in the CRPC state, varying from 1 yr to 4 yr according to risk category.Patient summary: It is possible to accurately estimate the disease trajectory and duration for men with castration-resistant prostate cancer.(c) 2022 The Authors.
