RESUMO
BACKGROUND: There are no population-level studies assessing 18F-fluciclovine (fluciclovine) utilization of Positron emission tomography/computed tomography (PET/CT) for biochemically recurrent prostate cancer (PC). We assessed fluciclovine PET/CT in the Veterans Affairs Health Care System. METHODS: Of 1153 men with claims suggesting receipt of fluciclovine PET/CT, we randomly reviewed charts of 300 who indeed underwent fluciclovine PET/CT. The primary outcome was fluciclovine PET/CT result (positive or negative). Comparison among groups stratified by androgen deprivation therapy (ADT) (yes vs. no) and prostate-specific antigen (PSA) (≤1 vs. >1 ng/mL) at imaging were performed. Logistic regression tested associations between PSA, ADT receipt, and race with fluciclovine PET/CT positive imaging. RESULTS: Fluciclovine PET/CT positivity rate was 33% for patients with PSA 0-0.5 ng/mL, 21% for >0.5-1.0, 54% for >1.0-2.0, and 66% for >2.0 (p < 0.01). A 59% positivity rate ocurred in patients treated with concurrent ADT versus 37% in those not on ADT (p < 0.01). White were more likely to have a positive scan versus Black patients (55% vs. 38%; p = 0.02). Patients whose primary treatment was radical prostatectomy had a lower positivity rate (33%) versus those treated with radiotherapy (55%) (p < 0.001). On multivariable logistic regression, PSA > 1 ng/mL (all men odds ratio [OR]: 4.06, 95% confidence interval [CI]: 2.07-7.96; men on ADT only OR: 4.42, 95% CI: 1.73-11.26) and use of ADT (OR: 3.94, 95% CI: 1.32-11.75), and White (all men OR: 2.22, 95% CI: 1.20-4.17) predicted positive fluciclovine PET/CT. CONCLUSION: This real-world study assessing 18F-fluciclovine PET/CT performance in an equal access health care system confirms higher detection rates than traditional imaging methods, but positivity is highly influenced by PSA at time of imaging. Additionally, patients currently receiving ADT have at least four times higher likelihood of a positive scan, showing that scan positivity isn't negatively affected by ADT status in this study. Finally, White men were more likely to have a positive scan, the reasons for which should be explored in future studies.
RESUMO
OBJECTIVE: To examine the association of anesthesiologist sex on postoperative outcomes. BACKGROUND: Differences in patient postoperative outcomes exist, depending on whether the primary surgeon is male or female, with better outcomes seen among patients treated by female surgeons. Whether the intraoperative anesthesiologist's sex is associated with differential postoperative patient outcomes is unknown. METHODS: We performed a population-based, retrospective cohort study among adult patients undergoing one of 25 common elective or emergent surgical procedures from 2007 to 2019 in Ontario, Canada. We assessed the association between the sex of the intraoperative anesthesiologist and the primary end point of the adverse postoperative outcome, defined as death, readmission, or complication within 30 days after surgery, using generalized estimating equations. RESULTS: Among 1,165,711 patients treated by 3006 surgeons and 1477 anesthesiologists, 311,822 (26.7%) received care from a female anesthesiologist and 853,889 (73.3%) from a male anesthesiologist. Overall, 10.8% of patients experienced one or more adverse postoperative outcomes, of whom 1.1% died. Multivariable adjusted rates of the composite primary end point were higher among patients treated by male anesthesiologists (10.6%) compared with female anesthesiologists (10.4%; adjusted odds ratio 1.02, 95% CI: 1.00-1.05, P =0.048). CONCLUSIONS: We demonstrated a significant association between sex of the intraoperative anesthesiologist and patient short-term outcomes after surgery in a large cohort study. This study supports the growing literature of improved patient outcomes among female practitioners. The underlying mechanisms of why outcomes differ between male and female physicians remain elusive and require further in-depth study.

PURPOSE: To compare disease-free survival (DFS), overall survival (OS), and adverse events (AEs) among muscle-invasive urothelial carcinoma (MIUC) patients receiving adjuvant immune checkpoint inhibitors (ICIs) versus placebo/observation following radical surgery. METHODS: This was a systematic review/meta-analysis of all published phase 3 randomized controlled trials. MEDLINE, EMBASE, and Cochrane were searched from inception until April 4, 2024. Pooled hazard ratios (HR) and relative risks (RR), plus confidence intervals (CI), were generated using frequentist random-effects modeling. RESULTS: Three trials were identified: IMvigor010, CheckMate 274, and AMBASSADOR. In the overall cohort, adjuvant ICIs significantly improved DFS by 23% (HR = 0.77, 95% CI = 0.65-0.90). No DFS benefit was observed in patients with upper tract disease (HR = 1.19, 95% CI = 0.86-1.64). The highest magnitude of DFS benefit was observed among patients who had received prior neoadjuvant chemotherapy (HR = 0.69) and pathologic node-positive disease (HR = 0.75). A similar DFS benefit was observed irrespective of tumor PD-L1 status. Pooled OS demonstrated a 13% non-significant benefit (HR = 0.87, 95% CI = 0.75-1.01). Grade ≥ 3 immune-mediated AEs occurred in 8.6% and 2.1% of ICI and placebo/observation patients, respectively (RR = 4.35, 95% CI = 1.02-18.5). AEs leading to treatment discontinuation occurred in 14.3% and 0.9% of patients, respectively. CONCLUSION: Adjuvant ICIs confer a DFS benefit following radical surgery for MIUC, particularly among node-positive patients and those who received prior neoadjuvant chemotherapy. The lack of benefit for upper tract disease suggests that alternate adjuvant approaches, including chemotherapy, should be considered for these patients. Tumor PD-L1 status is not a predictive biomarker, highlighting the need for biomarkers in this setting.

BACKGROUND: We previously showed that within an equal-access health system, race was not associated with the time between prostate cancer (PC) diagnosis and radical prostatectomy (RP). However, in the more recent time-period of the study (2003-2007), Black men had significantly longer times to RP. We sought to revisit the question in a larger study population with more contemporary patients. We hypothesized that time from diagnosis to treatment would not differ by race, even after accounting for active surveillance (AS) and the exclusion of men at very low to low risk of PC progression. METHODS: We analyzed data from 5885 men undergoing RP from 1988 to 2017 at eight Veterans Affairs Hospitals from SEARCH. Multiple linear regression was used to compare time from biopsy to RP and to examine the risk of delays (>90 and >180 days) between races. In sensitivity analyses we excluded men deemed to have initially chosen AS based on having >365 days from biopsy to RP and men at very low to low PC risk for progression according to National Comprehensive Cancer Network Clinical Practice Guidelines. RESULTS: At biopsy, Black men (n = 1959) were younger, had lower body mass index, and higher prostate specific antigen levels, (all p < 0.02), compared to White men (n = 3926). Time from biopsy to RP was longer in Black men (mean days: 98 vs. 92; adjusted ratio of mean number of days, 1.07 [95% confidence interval: 1.03-1.11], p < 0.001); however, there were no differences in delays >90 or >180 days after adjusting for confounders (all p ≥ 0.286). Results were similar following the exclusion of men potentially under on AS and at very low and low risk. CONCLUSIONS: In an equal-access healthcare system, we did not find evidence of clinically relevant differences in time from biopsy to RP in Black versus White men.

PURPOSE: Obesity and smoking have been associated with poor prostate cancer (PC) outcomes. We investigated associations between obesity and biochemical recurrence (BCR), metastasis, castrate resistant-PC (CRPC), PC-specific mortality (PCSM), and all-cause mortality (ACM) and examined if smoking modified these associations. METHODS: We analyzed SEARCH Cohort data from men undergoing RP between 1990 and 2020. Cox regression models were used to estimate hazard ratios (HRs) and 95% confidence intervals (CIs) for associations between body mass index (BMI) as a continuous variable and weight status classifications (normal: 18.5 ≤ 25 kg/m2; overweight: 25-29.9 kg/m2; obese: ≥ 30 kg/m2) and PC outcomes. RESULTS: Among 6,241 men, 1,326 (21%) were normal weight, 2,756 (44%) overweight and 2159 (35%) obese; 1,841 (30%) were never-smokers, 2,768 (44%) former and 1,632 (26%) current-smokers. Among all men, obesity was associated with non-significant increased risk of PCSM, adj-HR = 1.71; 0.98-2.98, P = 0.057, while overweight and obesity were inversely associated with ACM, adj-HR = 0.75; 0.66-0.84, P < 0.001 and adj-HR = 0.86; 0.75-0.99, P = 0.033, respectively. Other associations were null. BCR and ACM were stratified for smoking status given evidence for interactions (P = 0.048 and P = 0.054, respectively). Among current-smokers, overweight was associated with an increase in BCR (adj-HR = 1.30; 1.07-1.60, P = 0.011) and a decrease in ACM (adj-HR = 0.70; 0.58-0.84, P < 0.001). Among never-smokers, BMI (continuous) was associated with an increase in ACM (adj-HR = 1.03; 1.00-1.06, P = 0.033). CONCLUSIONS: While our results are consistent with obesity as a risk factor for PCSM, we present evidence of effect modification by smoking for BCR and ACM highlighting the importance of stratifying by smoking status to better understand associations with body weight.

This is a summary of existing systematic reviews comparing robotic assisted radical cystectomy (RARC) with open radical cystectomy (ORC). Our aim was to compare operative approaches with respect to perioperative, postoperative, oncologic, and health-related quality of life (QOL) outcomes. We performed a systematic review of MEDLINE, Medline-in-Process and Medline Epubs Ahead of Print, and the Cochrane Library on 22 February 2022. We included reviews of adult patients with bladder cancer undergoing RARC or ORC for muscle invasive or high-risk non-muscle invasive bladder cancer. Nonrandomized studies were excluded to minimize confounding and selection bias. The GRADE approach was used to determine the confidence in estimates. We assessed the quality of identified systematic reviews using AMSTAR 2 checklist. Six well-conducted, systematic reviews and meta-analyses were included. RARC was consistently associated with lower estimated blood loss (EBL) and transfusion rates, and longer operative time. There was inconsistent evidence for the impact of RARC on hospital length of stay (LOS). There was no significant difference in overall complication rate or major complication rate, or oncologic outcomes between groups. Comparison of QOL outcomes between studies was limited by statistical and methodological heterogeneity. RARC is associated with improvement in EBL and transfusion risk. There does not appear to be differences in oncologic outcomes or complications between approaches. Prospective studies are needed to assess the impact of diversion type, technique, and recovery pathways on patient outcomes and to assess the impact of operative approach on cost and patient-reported QOL.

OBJECTIVES: To synthesise available data regarding the disease-free survival (DFS) benefit of adjuvant immune checkpoint inhibitors (ICIs) for patients with renal cell carcinoma (RCC) and evaluate the overall safety profile of ICIs in this setting. MATERIALS AND METHODS: We utilised PubMed, Embase, and relevant conference proceedings to identify phase III randomised controlled trials comparing adjuvant ICIs vs placebo/observation for RCC. The primary outcome of interest was DFS. Variables for subgroup analyses were programmed death-ligand 1 (PD-L1) expression, sarcomatoid features, nephrectomy type, and disease-risk category. Secondary outcomes included Grade ≥3 adverse events (AEs), immune-related AEs, and treatment discontinuation due to AEs. All outcomes were analysed using random-effects models owing to inter-study heterogeneity. RESULTS: Among the four included studies, one demonstrated a significant DFS benefit. There was considerable clinical and statistical heterogeneity (I2 = 64%) due to differences in inclusion criteria and interventions. While pooled results across the four studies did not demonstrate a significant benefit in DFS overall (hazard ratio [HR] 0.85, 95% confidence interval [CI] 0.69-1.04) there was significant benefit among patients with positive PD-L1 expression (HR 0.72, 95% CI 0.55-0.94) and sarcomatoid features (HR 0.59, 95% CI 0.38-0.91). CONCLUSION: The evidence base to date regarding ICIs as adjuvant therapy in RCC is mixed - conclusions are limited by considerable heterogeneity between studies. However, pooled analyses suggest that patients with positive PD-L1 expression or sarcomatoid features are most likely to benefit from adjuvant immunotherapy.

OBJECTIVE: To assess, the effect of darolutamide (a structurally distinct androgen receptor inhibitor) on urinary and bowel symptoms, using data from the phase III ARAMIS trial (NCT02200614) that showed darolutamide significantly reduced the risk of metastasis and death versus placebo. PATIENTS AND METHODS: Patients with non-metastatic castration-resistant prostate cancer (nmCRPC) were randomised 2:1 to darolutamide (n = 955) or placebo (n = 554). Local symptom control was assessed by first prostate cancer-related invasive procedures and post hoc analyses of time to deterioration in quality of life (QoL) using total urinary and bowel symptoms, and individual questions for these symptoms from the European Organisation for Research and Treatment of Cancer Quality of Life Questionnaire Prostate Cancer Module subscales and Functional Assessment of Cancer Therapy-Prostate prostate cancer subscale. Prostate-specific antigen (PSA) responses were correlated with urinary and bowel adverse events (AEs). RESULTS: Fewer patients receiving darolutamide (4.7%) versus placebo (9.6%) underwent invasive procedures, and time to first procedure was prolonged with darolutamide (hazard ratio 0.42, 95% confidence interval 0.28-0.62). Darolutamide significantly (P < 0.01) delayed worsening of QoL for total urinary and bowel symptoms versus placebo, mostly attributed by individual symptoms of urinary frequency, associated pain, and interference with daily activities. AEs of urinary retention and dysuria were less frequent with darolutamide, and greater PSA response (≥90%, ≥50% and <90%, <50%) among darolutamide-treated patients was associated with lower incidences of urinary retention (2.2%, 4.2%, 5.1%) and dysuria (0.5%, 3.2%, 5.1%), respectively. CONCLUSIONS: Darolutamide demonstrated a positive impact on local disease recurrence and symptom control in patients with nmCRPC, delayed time to deterioration in QoL related to urinary and bowel symptoms, and a favourable safety profile showing similar incidence of urinary- and bowel-related AEs compared with placebo.

OBJECTIVES: To compare radiographic progression-free survival (rPFS), overall survival (OS), and treatment-emergent adverse events (TEAEs) among patients with metastatic castrate-resistant prostate cancer (mCRPC) receiving a combination of first-line poly(adenosine diphosphate-ribose) polymerase inhibitors (PARPi) plus androgen receptor axis-targeted agents (ARAT) vs placebo/ARAT. MATERIALS AND METHODS: We conducted a systematic review/meta-analysis of all published Phase III randomised controlled trials using EMBASE, MEDLINE, and Cochrane (inception until 6 June 2023). Published full-text manuscripts and conference abstracts were inclusion eligible. Study selection/data extraction were independently performed by two authors. The Cochrane Risk-of-Bias 2 Tool was used, and certainty of evidence assessed using the Grading of Recommendations, Assessment, Development, and Evaluations framework. Pooled hazard ratios (HRs) and relative risks, with corresponding confidence intervals (CIs), were generated using random-effects models. RESULTS: Three trials were identified: PROpel, MAGNITUDE, and TALAPRO-2. Compared to placebo/ARAT, the PARPi/ARAT combination was associated with a 35% rPFS improvement in the overall cohort (HR 0.65, 95% CI 0.56-0.76), with 68%, 45%, and 26% improvements in the BReast CAncer gene 1/gene 2 (BRCA1/2)-mutated (BRCA1/2m; P < 0.001), homologous recombination repair-mutated (HRRm; P < 0.001), and non-HRRm cohorts (P = 0.003), respectively. OS data maturity ranged from 31% to 48%, with overall cohort OS data unavailable from MAGNITUDE. The PROpel/TALAPRO-2 pooled analysis demonstrated a 16% OS improvement in the overall cohort (HR 0.84, 95 CI 0.72-0.98; P = 0.02). OS in the HRRm (HR 0.76, 95% CI 0.61-0.95) and the BRCA1/2m cohorts (HR 0.53, 95% CI 0.18-1.56) were improved, with a higher effect magnitude compared to the overall cohort. This combination was associated with a 45% relative risk increase in Grade ≥3 TEAEs, including 6.22-fold for Grade ≥3 anaemia (31.9% vs 4.9%). CONCLUSIONS: The addition of PARPi to ARAT in the first-line mCRPC setting is associated with rPFS benefits across subgroups, with the greatest magnitude of benefit in BRCA1/2m patients. OS benefits remain inconsistent irrespective of HRRm status, with significant increases in Grade ≥3 TEAEs, particularly anaemia. Currently, we suggest this combined approach be selectively offered to HRRm patients, preferentially BRCA1/2m.

PURPOSE: To determine prostate cancer (PCa) and other-cause mortality rates in low- and favorable intermediate-risk (FIR) active surveillance (AS) patients. METHODS: The SEER Prostate with Watchful Waiting database was used to identify men diagnosed with NCCN low or FIR PCa, between 2010 and 2015, managed with AS. FIR patients were subdivided into three subgroups, based on their intermediate risk factor: grade group two (GG2), PSA 10-20 ng/ml or cT2b-c disease. Cumulative incidence function curves with other-cause mortality as the competing risk were utilized. Predictors of PCa mortality were assessed using multivariable regression analysis with semi-parametric proportional hazards modeling. RESULTS: Among 70,871 patients, 48,127 (67.9%) had low and 22,744 (32.1%) had FIR disease. Median patient age was 64.0 years, and median PSA was 5.70 ng/ml. Median follow-up was 49.0 months. There were 166 (0.2%) PCa and 3,176 (4.48%) other-cause mortalities. The 5-year mortality rates in the low and FIR cohorts overall were 0.29% and 0.28%, respectively (p = 0.64). Within the FIR cohort, the corresponding rates were highest in the PSA 10-20 ng/ml subgroup at 0.73%, followed by 0.32% for GG2 FIR and 0.052% for cT2b-c FIR disease (p < 0.001). Older age at diagnosis (sHR 2.38, p = 0.006), Medicaid insurance (sHR: 2.58, p < 0.001), low socioeconomic (sHR 1.39, p = 0.032), and non-married statuses (sHR: 2.58, p < 0.001) were associated with increased PCa mortality. CONCLUSION: Intermediate-term PCa mortality rates in FIR PCa patients are non-significantly different to those with low-risk PCa. However, there is significant within-group heterogeneity, with PCa mortality rates significantly higher in the PSA 10-20 subgroup.

PURPOSE OF REVIEW: Metastatic prostate cancer remains universally lethal. Although de-novo metastatic prostate cancer was historically managed with systemic therapy alone, local therapies are increasingly utilized in the early treatment of the disease, particularly in patients with oligometastatic prostate cancer (OMPC). OMPC represents an intermediate stage between clinically localized and widespread metastatic disease. Diseases classified within this stage present an opportunity for localized targeting of the disease prior to progression to widespread metastases. The purpose of this review is to discuss the contemporary and emerging local therapies for the treatment of OMPC. RECENT FINDINGS: To date, there are three utilized forms of local therapy for OMPC: cryoablation, radiation therapy, and cytoreductive prostatectomy. Cryoablation can be utilized for the total ablation of the prostate and has shown promising results in patients with OMPC either in combination with ADT or with ADT and systemic chemotherapy. Radiation therapy along with ADT has demonstrated improvement in progression-free survival. The STAMPEDE Arm G, PEACE-1, and the HORRAD clinical trials have investigated radiation therapy for mPCa compared to standard of care versus systemic therapy with varying results. Cytoreductive radical prostatectomy (CRP) in conjunction with ADT has also been proposed in the management of OPMC with promising results from case-control and retrospective studies. Currently there are larger controlled trials investigating CRP for OPMC including the SIMCAP, LoMP, TRoMbone, SWOG 1802, IP2-ATLANTA, g-RAMPP, and FUSCC-OMPCa trials. Given the novel nature of local treatments for OPMC, treatment selection is still controversial and requires long-term follow-up and randomized clinical trials to aid patient and clinician decision making.

AIM: While high estimated glomerular filtration rate (eGFR) has been associated with increased overall mortality, its effect on postoperative outcomes is relatively understudied. We sought to investigate the association between high eGFR and 30-day postoperative outcomes using a multi-specialty surgical cohort. METHODS: Using the National Surgical Quality Improvement Program database, we selected adult for whom eGFR could be calculated using the 2021 Chronic Kidney Disease Epidemiology Collaboration equation. Based on sex-specific distributions of eGFR stratified by age quintiles, we classified patients into low (<5th percentile), normal (5-95th percentile) and high eGFR (>95th percentile). The primary outcome was a composite of any 30-day major adverse outcomes, including: death, reoperation, cardiac arrest, myocardial infarction and stroke. Secondary outcomes included 30-day infectious complications, venous thromboembolism (VTE), bleeding requiring transfusion, prolonged length of stay and unplanned readmission. After matching for demographic differences, comorbidity burden and operative characteristics, logistic regression models were used to evaluate the association between extremes of eGFR and the outcomes of interest. RESULTS: Of 1 668 447 patients, 84 115 (5.07%) had a high eGFR. High eGFR was not associated with major adverse outcomes (odds ratio [OR] 1.00 [95% confidence interval (CI): 0.97, 1.03]); however, it was associated with reoperation (OR 1.04 [95% CI: 1.00,1.08]), infectious complications (OR 1.14 [95% CI: 1.11, 1.16]), VTE (OR 1.15 [95% CI: 1.09, 1.22]) and prolonged length of stay (OR 1.19 [95% CI: 1.16, 1.21]). CONCLUSION: Our findings support an association between high eGFR and adverse 30-day postoperative outcomes.

BACKGROUND: Follicle stimulating hormone (FSH) is a pituitary hormone that helps regulate testosterone homeostasis. Although it is generally accepted that FSH levels increase with LHRH-agonist therapy for prostate cancer (PC), the specific impact of FSH levels on risk of PC diagnosis is largely unknown. The objective of this study was to perform a population-level analysis to assess the association between FSH levels and PC diagnosis. METHODS: All men (n = 386,018) who had a pre-PC diagnosis FSH level and complete data were identified within the Veterans Affairs Health System between 1999 and 2018. The association between FSH level and time from FSH test to PC diagnosis was tested using stratified Cox proportional hazards models. Multivariable models were adjusted for age, year, race, body mass index, and Charlson comorbidity index. Due to nonproportional hazards over time, time to PC was modeled separately: ≤4 years after an FSH test and >4 years following an FSH test. RESULTS: Median age at first FSH level was 64 years (interquartile range [IQR]: 54-72), median year of FSH was 2010 (IQR: 2005-2014), and 70% of the cohort was white. Median follow-up was 76 months (IQR: 38-126) during which 17,519 men (4.5%) were diagnosed with PC. On multivariable analysis, in the first 4 years after FSH test, there was no association between FSH and time to PC diagnosis. Starting from 4 years after FSH test, on multivariable analysis, a higher FSH level was associated with lower risk of PC with continuous modeling, but found no association with log continuous and categorical modeling. CONCLUSIONS: In this population-level study among male veterans receiving an FSH test for an unknown clinical indication, associations between FSH levels and PC risk were inconsistent and likely driven by selection bias and confounding variables. Future studies should consider different study designs.

BACKGROUND: Smaller prostates have been linked to unfavorable clinical characteristics and poor short-term outcomes following radical prostatectomy (RP). We examined the relation between prostate weight at RP and prostate cancer (PC) outcomes post-RP. METHODS: Men in the SEARCH cohort undergoing RP between 1988 and 2017 (N = 6242) were studied for PC-specific mortality (PCSM) as the primary outcome, and for biochemical recurrence (BCR), castration-resistant PC (CRPC) and metastasis as secondary outcomes. Hazard ratios (HR) and 95% confidence intervals (CI) were determined for associations between prostate weight and outcomes using Fine-Gray competing risk regression multivariable analyses. Sensitivity analyses were also carried out following exclusion of: (i) men with extreme prostate weights (<20 g and ≥100 g); and (ii) men with elevated prostate specific antigen (PSA) levels. RESULTS: Median values for age, pre-RP PSA and prostate weight were 63 years, 6.6 ng/ml, and 42.0 g, respectively. During a median follow-up of 7.9 years, 153 (3%) died from PC, 2103 (34%) had BCR, 203 (3%) developed CRPC, and 289 (5%) developed metastases. Prostate weight was not associated with PCSM in the main analyses (multivariable HR = 1.43; 95% CI: 0.87-2.34) or in sensitivity analyses. Prostate weight was inversely associated with BCR in the main analyses (multivariable HR = 0.70; 95%CI: 0.61-0.79) which was unchanged in sensitivity analyses. HRs for prostate weight and CRPC and metastasis were elevated but statistical significance was not attained. Similar results were observed in sensitivity analyses. CONCLUSIONS: Inconsistent results for prostate weight and short-term vs longer-term outcomes highlight the need to better understand the complex biology leading to prostate size and the relevance of prostate size as a predictor of PC outcomes.

OBJECTIVE: The aim of this study was to examine the effect of surgeon-anesthesiologist sex discordance on postoperative outcomes. SUMMARY BACKGROUND DATA: Optimal surgical outcomes depend on teamwork, with surgeons and anesthesiologists forming two key components. There are sex and sex-based differences in interpersonal communication and medical practice which may contribute to patients' perioperative outcomes. METHODS: We performed a population-based, retrospective cohort study among adult patients undergoing 1 of 25 common elective or emergent surgical procedures from 2007 to 2019 in Ontario, Canada. We assessed the association between differences in sex between surgeon and anesthesiologists (sex discordance) on the primary endpoint of adverse postoperative outcome, defined as death, readmission, or complication within 30âdays following surgery using generalized estimating equations. RESULTS: Among 1,165,711 patients treated by 3006 surgeons and 1477 anesthesiologists, 791,819 patients were treated by sex concordant teams (male surgeon/male anesthesiologist: 747,327 and female surgeon/female anesthesiologist: 44,492), whereas 373,892 were sex discordant (male surgeon/female anesthesiologist: 267,330 and female surgeon/male anesthesiologist: 106,562). Overall, 12.3% of patients experienced >1 adverse postoperative outcomes of whom 1.3% died. Sex discordance between surgeon and anesthesiologist was not associated with a significant increased likelihood of composite adverse postoperative outcomes (adjusted odds ratio 1.00, 95% confidence interval 0.97-1.03). CONCLUSIONS: We did not demonstrate an association between intraoperative surgeon and anesthesiologist sex discordance on adverse postoperative outcomes in a large patient cohort. Patients, clinicians, and administrators may be reassured that physician sex discordance in operating room teams is unlikely to clinically meaningfully affect patient outcomes after surgery.

OBJECTIVES: To determine the geographic distribution of muscle-invasive bladder cancer mortality according to race in the United States (US). African Americans (AAs) have up to two times the risk of bladder cancer mortality compared to Caucasians. Bladder cancer mortality increases exponentially once it invades the muscle. Geographic heterogeneity in bladder cancer mortality according to race remains to be determined. DESIGN: Analysis of Surveillance, Epidemiology, and End Results (SEER)-Medicare data for 6,044 patients aged 66-85 diagnosed with clinical stage T2-T4 N0M0 bladder cancer from 1 January 2002 to 31 December 2011. Fine and Gray-competing risks regression models were used to assess the association of race with bladder cancer-specific mortality (BCSM) according to tumor registry. RESULTS: Out of 6,044 patients, 5,408 (89.5%) were Caucasian, 352 (5.82%) were non-Hispanic AA, 85 (1.4%) were Hispanic, and 199 (3.29%) were other. Of the 18 registries, AAs with bladder cancer were largely concentrated in Louisiana (19%), New Jersey (17.9%), and Georgia (17.6%). New Jersey was the only registry where AAs had increased risk of BCSM than Caucasians and only for stage T2 disease: (AHR, 1.74; 95% CI 1.22-2.47, p = 0.002). According to treatment, AAs in New Jersey had worse BCSM than Caucasians when they underwent radical cystectomy (AHR, 2.05; 95% CI 1.26-3.35, p = 0.0039) and radiotherapy or chemotherapy alone (AHR, 1.55; 95% CI 1.03-2.35, p = 0.0367). CONCLUSIONS: We observed geographic variation in bladder cancer mortality which impacted only one registry with one of the largest population of AAs. These findings support further investigation into the social determinants of race (i.e., socioeconomic status and distance to healthcare facility) and culturally centered healthcare decision making which may drive these results.

PURPOSE: To systematically review the literature to investigate racial disparities among bladder cancer clinical trial enrollees. METHODS: A systematic review was conducted using Ovid, MEDLINE® to identify clinical trials between 1970 and 2020. Articles were reviewed and were included if they assessed race in their outcomes reporting among bladder cancer patients enrolled in clinical trials. The review was conducted in accordance with the PRISMA statement. RESULTS: We identified 544 clinical trials meeting our initial search criteria, with only 24 (4.4%) studies reporting racial demographic data. Enrollees were largely Caucasian (81-98%), with a strikingly small proportion of enrolled patients consisting of African-Americans (2-8%) and Hispanics (2-5%). Only one of the studies reported results on the efficacy and safety/tolerability of the tested treatment separately for racial groups and performed analyses stratified by race. CONCLUSION: Race is poorly studied in bladder cancer clinical trials. Trial cohorts may not reflect multicultural populations. The potential association between race and efficacy, safety or tolerability of the tested interventions is unknown. Given the up to twofold increase in bladder cancer-specific death among African-Americans, further research is needed to address the impact of race in clinical trials, while encompassing socioeconomic factors and disease risk factor exposures.

PURPOSE: There are limited data regarding the effect of treatment delays on important long-term outcomes among men with intermediate/high-risk prostate cancer (PC). MATERIALS AND METHODS: We identified 3,962 men with intermediate/high-risk disease from the SEARCH cohort treated with radical prostatectomy (RP) from 1988 to 2018. Cox proportional hazard models assessed the association between time from biopsy to RP (up to 1 year) and time to castration-resistant PC (CRPC), metastasis and all-cause mortality. Interaction terms were used to test for effect modification by risk group. RESULTS: Of the 3,962 men, 167 developed CRPC, 248 developed metastases and 884 died after a median followup of 85 months. Longer delays between biopsy and RP were associated with a decreased risk of CRPC (adjusted HR=0.88, 95% CI: 0.80-0.98, p=0.02), independent of D'Amico risk group (interaction p >0.05). In men with intermediate and high-risk disease, we found no statistically significant association between length of time to RP and risk of developing metastases (p=0.5 and 0.9, respectively) or all-cause mortality (p=0.1 and 0.1, respectively). CONCLUSIONS: Among men with intermediate and high-risk PC, we found no statistically significant increased risk of adverse long-term outcomes, including CRPC, metastasis and death, for men who had treatment delays up to 1 year following PC diagnosis.

PURPOSE: We aimed to compare patient-reported mental health outcomes for men undergoing treatment for localized prostate cancer longitudinally over 5 years. MATERIALS AND METHODS: We conducted a prospective population-based analysis using the Comparative Effectiveness Analysis of Surgery and Radiation (CEASAR) study. Patient-reported depressive symptoms (Centers for Epidemiologic Studies Depression [CES-D]) and domains of the Medical Outcomes Study 36-item Short Form survey evaluating emotional well-being and energy/fatigue were assessed through 5 years after treatment with surgery, radiotherapy (with or without androgen deprivation therapy) and active surveillance. Regression models were adjusted for outcome-specific baseline function, demographic and clinicopathological characteristics, and treatment approach. RESULTS: A total of 2,742 men (median [quartiles] age 64 [59-70]) met inclusion criteria. Baseline depressive symptoms, as measured by the CES-D, were low (median 4, quartiles 1-8) without differences between groups. We found no effect of treatment modality on depressive symptoms (p=0.78), though older age, poorer health, being unmarried and baseline CES-D score were associated with declines in mental health. There was no clinically meaningful association between treatment modality and scores for either emotional well-being (p=0.81) or energy/fatigue (p=0.054). CONCLUSIONS: This prospective, population-based cohort study of men with localized prostate cancer showed no clinically important differences in mental health outcomes including depressive symptoms, emotional well-being, and energy/fatigue according to the treatment received (surgery, radiotherapy, or surveillance). However, we identified a number of characteristics associated with worse mental health outcomes including: older age, poorer health, being unmarried, and baseline CES-D score which may allow for early identification of patients most at risk of these outcomes following treatment.

We conducted a cross-sectional analysis of ClinicalTrials.gov-registered oncology randomized controlled trials between September 2019 and December 2021 to identify predictors of trial suspensions. The dataset included 1,183 oncology trials, of which 384 (32.5%) were suspended. COVID-19 accounted for 47 (12.2%) suspensions. Trials that were single center- or US-based had higher odds of COVID-19 (ORs: 3.85 and 2.48, 95% CIs: 1.60-11.50 and 1.28-4.93, respectively) or any-reason suspensions (ORs: 2.33 and 2.04, 95% CIs: 1.46-3.45 and 1.40-2.76, respectively). Phase two (OR 1.27), three (OR 6.45) and four trials (OR 11.5) had increased odds of COVID-19 suspensions, compared to phase one trials.
