Prostate-specific antigen (PSA)-based screening for prostate cancer (PCa) can reduce PCa mortality, but also involves overdetection of low-risk disease with potential adverse effects. We evaluated PCa incidence among men with PSA below 3 ng/mL and no PCa diagnosis at the first screening round of the Finnish Randomized Study of Screening for PCa. Follow-up started at the first screening attendance and ended at PCa diagnosis, emigration, death or the common closing date (December 2016), whichever came first. Cox regression analysis was used to estimate hazard ratios and their confidence intervals (CI). Among men with PSA <3 ng/mL, cumulative PCa incidence was 9.1% after 17.6 years median follow-up. Cumulative incidence was 3.6% among men with baseline PSA 0 to 0.99 ng/mL, 11.5% in those with PSA 1.0 to 1.99 ng/mL and 25.7% among men with PSA 2 to 2.99 ng/mL (hazard ratio 9.0, 95% CI: 7.9-10.2 for the latter). The differences by PSA level were most striking for low-risk disease based on Gleason score and EAU risk group. PSA values <1 ng/mL indicate a very low 20-year risk, while at PSA 2 to 2.99 ng/mL risks are materially higher, with 4- to 5-fold risk for aggressive disease. Using risk-stratification and appropriate rescreening intervals will reduce screening intensity and overdetection. Using cumulative incidence of clinically significant PCa (csPCa) as the criterion, rescreening intervals could range from approximately 3 years for men with initial PSA 2 to 2.99 ng/mL, 6 years for men with PSA 1 to 1.99 ng/mL to 10 years for men with PSA <1 ng/mL. 相似文献

IntroductionErectile dysfunction is common after radical prostatectomy because of damage to the cavernous nerves. Thus, it is important to identify new ways to avoid this problem. For example, statins have shown positive effects on erectile function and may have anti-inflammatory effects that improve recovery after surgery.AimThe aim of this exploratory analysis of a subgroup from ESTO1, a randomized, double-blind, placebo-controlled study, was to evaluate the preoperative use of atorvastatin on erectile function after radical prostatectomy.MethodPatients were randomized to either 80 mg atorvastatin or placebo daily before undergoing radical prostatectomy from study inclusion to the day of surgery. Altogether 118 men with prostate cancer and scheduled for radical prostatectomy were asked to fill out the 5-item version of the International Index of Erectile Function (IIEF-5) questionnaire before surgery and at 3, 6, 9, and 12 months after surgery.Main Outcome MeasurementsThe study was exploratory, with the main outcome being the overall difference between IIEF-5 scores in the 2 groups at 12 months. Several hypotheses generating sub-analyses were conducted.ResultsOverall, 85% filled out the IIEF-5 questionnaire before their operation and 85%, 81%, 78%, and 78% completed it at 3, 6, 9, and 12 months follow-up, respectively. 52% of men had information available at all time points. There were no statistically significant differences between the groups at baseline in either erectile function, comorbidities, or tumor characteristics. The median duration of use of atorvastatin and placebo before surgery was 27 and 25 days, respectively. Preoperative atorvastatin treatment had no statistically significant effect on erectile function after prostatectomy as compared with placebo, although IIEF-5 scores were higher at all time points in the statin arm. Furthermore, atorvastatin treatment compared with placebo improved IIEF-5 scores at 12 months after surgery when the cavernous nerves were at least partially intact bilaterally (P < .04, n = 65); however, after full bilateral or unilateral nerve-sparing, the difference was not statistically significant.Clinical ImplicationShort-term statin treatment did not improve recovery of erectile function after prostatectomy; however, further studies are needed before final conclusions.Strengths & LimitationsThis was a randomized placebo-controlled study. Original ESTO1 study was designed to detect a difference in prostate cancer biomarkers.ConclusionShort-term atorvastatin treatment before radical prostatectomy had no statistically significant effect on the recovery of erectile functions in a non-selected cohort of patients undergoing radical prostatectomy. Further studies will be needed to clarify the role of long-term atorvastatin use before and after prostatectomy.Siltari A, Riikonen J, Fode M, et al.
