Prostate-Specific Antigen Screening in Smokers: A Comprehensive Analysis Using a National Behavioral Survey
Cigarette smoking is associated with higher-risk prostate cancer at the time of diagnosis and increased overall and prostate cancer‒specific mortality. Previous studies indicate smokers are less likely to undergo PSA screening. Herein we investigate the association between smoking and PSA screening using a nationally representative US survey. We hypothesize that smokers are less likely to undergo guideline-concordant PSA screening. We performed a cross-sectional analysis of men aged 55 to 69 who responded to the cigarette smoking and PSA screening questions of the 2018 Behavioral Risk Factor Surveillance System survey. Adjusted prevalence and adjusted risk differences were calculated using complex weighted multivariable Poisson regression modeling. We identified 58,996 individuals who qualified for analysis. PSA screening prevalence was 39% (95% CI: 39%-40%) nationally, 42% (95% CI: 41%-44%) for never smokers, 42% (95% CI: 39%-40%) for former smokers, and 27% (95% CI: 25%-29%) for current smokers, including 27% (95% CI: 24%-29%) for daily smokers and 29% (95% CI: 24%-33%) for nondaily smokers. Compared to never smokers, the adjusted relative risk for undergoing PSA screening was 0.81 for current smokers (95% CI: 0.75-0.88, P < .01) and 0.99 for former smokers (95% CI: 0.94-1.03, P = .53). Current smokers are less likely to undergo recommended PSA screening, but former smokers are screened at similar rates as never smokers. As delays in diagnosis may substantially contribute to worse prostate cancer outcomes, targeted interventions to increase screening in this population may yield significant effects.

Diminished Short-Term Efficacy of Reduced-Dose Induction BCG in the Treatment of Non-Muscle Invasive Bladder Cancer
The ongoing Bacillus Calmette-Guérin (BCG) shortage has created challenges for the treatment of non-muscle invasive bladder cancer (NMIBCa). Our objective was to evaluate the efficacy of reduced-dose induction BCG (RD-iBCG) compared to full-dose induction BCG (FD-iBCG) regarding recurrence rates. We hypothesized that patients receiving RD-iBCG may recur at a higher rate compared to those who received FD-iBCG therapy. A retrospective review of all patients with NMIBCa treated with intravesical therapy at our institution between 2015–2020 was conducted. Inclusion criteria consisted of having a diagnosis of AUA intermediate or high-risk NMIBCa with an indication for a six-week induction course of FD or RD-BCG with at least 1 year of documented follow up. The data were censored at one year. Propensity score matching for age, sex, tumor pathology, and initial vs. recurrent disease was performed. The primary endpoint was bladder cancer recurrence, reported as recurrence-free survival. A total of 254 patients were reviewed for this study. Our final cohort was 139 patients after exclusion. Thirty-nine percent of patients had HGT1 disease. 38.6% of patients receiving RD-BCG developed a recurrence of bladder cancer within a one-year follow-up as compared to 33.7% of patients receiving FD therapy. After propensity matching, this value remained statistically significant (p = 0.03). In conclusion, RD-iBCG for NMIBCa is associated with a significantly greater risk of recurrence than full-dose induction therapy, suggesting that RD-iBCG may not be equivalent or non-inferior to full-dose administration in the short term.

Role of Hysteropexy in the Management of Pelvic Organ Prolapse
Purpose of Review To discuss considerations for hysteropexy for apical pelvic organ prolapse (POP) and summarize available literature comparing various hysteropexy techniques to analogous procedures involving hysterectomy. Recent Findings Hysteropexy for apical POP has increased in popularity in recent years, although anatomic factors and gynecologic cancer risk must be taken into account. Native tissue hysteropexy options include the LeFort colpocleisis, sacrospinous hysteropexy, and uterosacral hysteropexy. Although vaginal mesh was banned by the Food and Drug Administration in 2019, abdominal mesh sacrohysteropexy done either open or laparoscopically remains an option in the USA. Overall, short-term prolapse outcomes appear to be comparable between uterus-sparing approaches and hysterectomy, with less blood loss and shorter operating room time observed with the uterine-sparing approaches, although long-term outcome data remains variable and limited. Summary Uterine-sparing apical POP repair may be offered to appropriate patients without certain risk factors, although longer-term data will be required to evaluate durability.
