Defining aggressive prostate cancer: a geospatial perspective.

BACKGROUND: Spatial analysis can identify communities where men are at risk for aggressive prostate cancer (PCan) and need intervention. However, there are several definitions for aggressive PCan. In this study, we evaluate geospatial patterns of 3 different aggressive PCan definitions in relation to PCan-specific mortality and provide methodologic and practical insights into how each definition may affect intervention targets. METHODS: Using the Pennsylvania State Cancer Registry data (2005-2015), we used 3 definitions to assign "aggressive" status to patients diagnosed with PCan. Definition one (D1, recently recommended as the primary definition, given high correlation with PCan death) was based on staging criteria T4/N1/M1 or Gleason score ≥ 8. Definition two (D2, most frequently-used definition in geospatial studies) included distant SEER summary stage. Definition three (D3) included Gleason score ≥ 7 only. Using Bayesian spatial models, we identified geographic clusters of elevated odds ratios for aggressive PCan (binomial model) for each definition and compared overlap between those clusters to clusters of elevated hazard ratios for PCan-specific mortality (Cox regression). RESULTS: The number of "aggressive" PCan cases varied by definition, and influenced quantity, location, and extent/size of geographic clusters in binomial models. While spatial patterns overlapped across all three definitions, using D2 in binomial models provided results most akin to PCan-specific mortality clusters as identified through Cox regression. This approach resulted in fewer clusters for targeted intervention and less sensitive to missing data compared to definitions that rely on clinical TNM staging. CONCLUSIONS: Using D2, based on distant SEER summary stage, in future research may facilitate consistency and allow for standardized comparison across geospatial studies.

Examining Obesity and Its Association With Burn Injury: A Secondary Analysis of the Transfusion Requirement in Burn Care Evaluation Study.

INTRODUCTION: Literature examining the connection between obesity and burn injuries is limited. This study is a secondary analysis of a multicenter trial data set to investigate the association between burn outcomes and obesity following severe burn injury. MATERIALS AND METHODS: Body mass index (BMI) was used to stratify patients as normal weight (NW; BMI 18.5-25), all obese (AO; any BMI>30), obese I (OI; BMI 30-34.9), obese II (OII; BMI 35-39.9), or obese III (OIII; BMI>40). The primary outcome examined was mortality. Secondary outcomes included hospital length of stay (LOS), number of transfusions, injury scores, infection occurrences, number of operations, ventilator days, intensive care unit LOS, and days to wound healing. RESULTS: Of 335 patients included for study, 130 were obese. Median total body surface area (TBSA) was 31%, 77 patients (23%) had inhalation injury and 41 patients died. Inhalation injury was higher in OIII than NW (42.1% versus 20%, P = 0.03). Blood stream infections (BSI) were higher in OI versus NW (0.72 versus 0.33, P = 0.03). Total operations, ventilator days, days to wound healing, multiorgan dysfunction score, Acute Physiology and Chronic Health Evaluationscore, hospital LOS, and intensive care unit LOS were not significantly affected by BMI classification. Mortality was not significantly different between obesity groups. Kaplan-Meier survival curves did not significantly differ between the groups (χ2 = 0.025, P = 0.87). Multiple logistic regression identified age, TBSA, and full thickness burn as significant independent predictors (P < 0.05) of mortality; however, BMI classification itself was not predictive of mortality. CONCLUSIONS: No significant association between obesity and mortality was seen after burn injury. Age, TBSA, and percent full- thickness burn were independent predictors of mortality after burn injury, while BMI classification was not.

Preference Elicitation and Treatment Decision-Making Among Men Diagnosed With Prostate Cancer: Randomized Controlled Trial Results of Healium.

BACKGROUND: Elicitation of patients' preferences is an integral part of shared decision-making, the recommended approach for prostate cancer decision-making. Existing decision aids for this population often do not specifically focus on patients' preferences. Healium is a brief interactive web-based decision aid that aims to elicit patients' treatment preferences and is designed for a low health literate population. OBJECTIVE: This study used a randomized controlled trial to evaluate whether Healium, designed to target preference elicitation, is as efficacious as Healing Choices, a comprehensive education and decision tool, in improving outcomes for decision-making and emotional quality of life. METHODS: Patients diagnosed with localized prostate cancer who had not yet made a treatment decision were randomly assigned to the brief Healium intervention or Healing Choices, a decision aid previously developed by our group that serves as a virtual information center on prostate cancer diagnosis and treatment. Assessments were completed at baseline, 6 weeks, and 3 months post baseline, and included decisional outcomes (decisional conflict, satisfaction with decision, and preparation for decision-making), and emotional quality of life (anxiety/tension and depression), along with demographics, comorbidities, and health literacy. RESULTS: A total of 327 individuals consented to participate in the study (171 were randomized to the Healium intervention arm and 156 were randomized to Healing Choices). The majority of the sample was non-Hispanic (272/282, 96%), White (239/314, 76%), married (251/320, 78.4%), and was on average 62.4 (SD 6.9) years old. Within both arms, there was a significant decrease in decisional conflict from baseline to 6 weeks postbaseline (Healium, P≤.001; Healing Choices, P≤.001), and a significant increase in satisfaction with one's decision from 6 weeks to 3 months (Healium, P=.04; Healing Choices, P=.01). Within both arms, anxiety/tension (Healium, P=.23; Healing Choices, P=.27) and depression (Healium, P=.001; Healing Choices, P≤.001) decreased from baseline to 6 weeks, but only in the case of depression was the decrease statistically significant. CONCLUSIONS: Healium, our brief decision aid focusing on treatment preference elicitation, is as successful in reducing decisional conflict as our previously tested comprehensive decision aid, Healing Choices, and has the added benefit of brevity, making it the ideal tool for integration into the physician consultation and electronic medical record.

Outcomes of Lymph Node Dissection in Nephroureterectomy in the Treatment of Upper Tract Urothelial Carcinoma: Analysis of the ROBUUST Registry.

PURPOSE: We sought to evaluate outcomes of lymph node dissection (LND) in patients with upper tract urothelial carcinoma. MATERIALS AND METHODS: We performed a multicenter retrospective analysis utilizing the ROBUUST (for RObotic surgery for Upper Tract Urothelial Cancer Study) registry for patients who did not undergo LND (pNx), LND with negative lymph nodes (pN0) and LND with positive nodes (pN+). Primary and secondary outcomes were overall survival (OS) and recurrence-free survival (RFS). Multivariable analyses evaluated predictors of outcomes and pathological node positivity. Kaplan-Meier analyses (KMAs) compared survival outcomes. RESULTS: A total of 877 patients were analyzed (LND performed in 358 [40.8%]/pN+ in 73 [8.3%]). Median nodes obtained were 10.2 for pN+ and 9.8 for pN0. Multivariable analyses noted increasing age (OR 1.1, p <0.001), pN+ (OR 3.1, p <0.001) and pathological stage pTis/3/4 (OR 3.4, p <0.001) as predictors for all-cause mortality. Clinical high-grade tumors (OR 11.74, p=0.015) and increasing tumor size (OR 1.14, p=0.001) were predictive for lymph node positivity. KMAs for pNx, pN0 and pN+ demonstrated 2-year OS of 80%, 86% and 42% (p <0.001) and 2-year RFS of 53%, 61% and 35% (p <0.001), respectively. KMAs comparing pNx, pN0 ≥10 nodes and pN0 <10 nodes showed no significant difference in 2-year OS (82% vs 85% vs 84%, p=0.6) but elicited significantly higher 2-year RFS in the pN0 ≥10 group (60% vs 74% vs 54%, p=0.043). CONCLUSIONS: LND during nephroureterectomy in patients with positive lymph nodes provides prognostic data, but is not associated with improved OS. LND yields ≥10 in patients with clinical node negative disease were associated with improved RFS. In high-grade and large tumors, lymphadenectomy should be considered.

Risk Factors for Intravesical Recurrence after Minimally Invasive Nephroureterectomy for Upper Tract Urothelial Cancer (ROBUUST Collaboration).

PURPOSE: Intravesical recurrence (IVR) after radical nephroureterectomy (RNU) for upper tract urothelial carcinoma (UTUC) has an incidence of approximately 20%-50%. Studies to date have been composed of mixed treatment cohorts-open, laparoscopic and robotic. The objective of this study is to assess clinicopathological risk factors for intravesical recurrence after RNU for UTUC in a completely minimally invasive cohort. MATERIALS AND METHODS: We performed a multicenter, retrospective analysis of 485 patients with UTUC without prior or concurrent bladder cancer who underwent robotic or laparoscopic RNU. Patients were selected from an international cohort of 17 institutions across the United States, Europe and Asia. Univariate and multiple Cox regression models were used to identify risk factors for bladder recurrence. RESULTS: A total of 485 (396 robotic, 89 laparoscopic) patients were included in analysis. Overall, 110 (22.7%) of patients developed IVR. The average time to recurrence was 15.2 months (SD 15.5 months). Hypertension was a significant risk factor on multiple regression (HR 1.99, CI 1.06; 3.71, p=0.030). Diagnostic ureteroscopic biopsy incurred a 50% higher chance of developing IVR (HR 1.49, CI 1.00; 2.20, p=0.048). Treatment specific risk factors included positive surgical margins (HR 3.36, CI 1.36; 8.33, p=0.009) and transurethral resection for bladder cuff management (HR 2.73, CI 1.10; 6.76, p=0.031). CONCLUSIONS: IVR after minimally invasive RNU for UTUC is a relatively common event. Risk factors include a ureteroscopic biopsy, transurethral resection of the bladder cuff, and positive surgical margins. When possible, avoidance of transurethral resection of the bladder cuff and alternative strategies for obtaining biopsy tissue sample should be considered.

The Balance between Open and Robotic Training among Graduating Urology Residents-Does Surgical Technique Need Monitoring?

PURPOSE: A minimum number of index procedures is required for graduation. Without thresholds for surgical technique, it is unclear if robotic and open learning is balanced. We assessed the distribution of robotic and open surgeries performed by residents upon graduation. MATERIALS AND METHODS: Voluntary Accreditation Council for Graduate Medical Education resident case logs from 11 institutions were de-identified and trends in robotic and open major surgeries were compared using Wilcoxon rank sum and 2-sample t-tests. RESULTS: A total of 89,199 major cases were recorded by 209 graduates from 2011 to 2017. The median proportion of robotic cases increased from 2011 to 2017 in reconstruction (4.7% to 15.2%), oncology (27.5% to 54.2%) and pediatrics (0% to 10.9%) (all values p <0.001). Robotic and open cases remained most divergent in reconstruction, with a median of 12 robotic (IQR 9-19) to 70 open cases (IQR 55-106) being performed by residents in 2017. Similar observations occurred in pediatrics. In oncology the number of robotic procedures superseded that of open in 2016 and rose to a median of 148 robotic (IQR 108-214) to 121 open cases (IQR 90-169) in 2017, with the driver being robotic prostatectomy. Substantial differences in surgical technique were observed between institutions and among graduates from the same institution. CONCLUSIONS: Although robotic volume is increasing, the balance of surgical technique and the pace of change differ in reconstruction, oncology and pediatrics, as well as among individual institutions and graduates themselves. This raises questions about whether more specific guidelines are needed to ensure equity and standardization in training.

Hospital-specific antibiograms and antibiotic prophylaxis for prostate biopsies: a reexamination of AUA recommendations.

INTRODUCTION: To assess whether standard American Urological Association (AUA) and other recommendations for prostate biopsy prophylaxis provide sufficient coverage of common urinary organisms responsible for post biopsy infections by comparing local antibiograms in Philadelphia-area hospitals. MATERIALS AND METHODS: De-identified culture results derived from antibiograms were collected from six academic and community hospitals in the Philadelphia region. Analysis specifically focused on four major bacterial causes of urinary tract infection following prostate biopsy (Escherichia coli (E. coli), Klebsiella pneumoniae, Proteus mirabilis and Enterococcus faecalis) along with commonly recommended antibiotics including fluoroquinolones (FQ's), trimethoprim/sulfamethoxazole, ceftriaxone, and gentamicin. RESULTS: Bacterial sensitivities to each antibiotic across institutions showed variation in E.coli sensitivities to FQs (p < 0.001), trimethoprim/sulfamethoxazole (p < 0.001), ceftriaxone (p < 0.001) and gentamicin (p < 0.001). Klebsiella pneumoniae and Proteus mirabilis exhibited similar variations. Sensitivity comparisons for Enterococcus faecalis was unable to be performed due to absent or incomplete data across institutions. CONCLUSION: Institutional antibiograms vary within our regional hospitals. Standardized recommendations for commonly used antibiotic prophylaxis such as fluoroquinolones may be inadequate for peri-procedural prostate biopsy prophylaxis based on local resistance patterns. Valuable information about the potential effectiveness of antibiotic prophylaxis for prostate biopsies can be found in local institutional antibiograms, and should be consulted when considering antibiotic prophylaxis for prostate biopsy procedures.

Active Surveillance as Initial Management of Newly Diagnosed Prostate Cancer: Data from the PURC.

PURPOSE: We describe contemporary active surveillance utilization and variation in a regional prostate cancer collaborative. We identified demographic and disease specific factors associated with active surveillance in men with newly diagnosed prostate cancer. MATERIALS AND METHODS: We analyzed data from the PURC (Pennsylvania Urologic Regional Collaborative), a cooperative effort of urology practices in southeastern Pennsylvania and New Jersey. We determined the rates of active surveillance among men with newly diagnosed NCCN® (National Comprehensive Cancer Network®) very low, low or intermediate prostate cancer and compared the rates among participating practices and providers. Univariate and multivariable analyses were used to identify factors associated with active surveillance utilization. RESULTS: A total of 1,880 men met inclusion criteria. Of the men with NCCN very low or low risk prostate cancer 57.4% underwent active surveillance as the initial management strategy. Increasing age was significantly associated with active surveillance (p <0.001) while adverse clinicopathological variables were associated with decreased active surveillance use. Substantial variation in active surveillance utilization was observed among practices and providers. CONCLUSIONS: More than 50% of men with low risk disease in the PURC collaborative were treated with active surveillance. However, substantial variation in active surveillance rates were observed among practices and providers in academic and community settings. Advanced age and favorable clinicopathological factors were strongly associated with active surveillance. Analysis of regional collaboratives such as the PURC may allow for the development of strategies to better standardize treatment in men with prostate cancer and offer active surveillance in a more uniform and systematic fashion.

African-American men with prostate cancer have larger tumor volume than Caucasian men despite no difference in serum prostate specific antigen.

INTRODUCTION: Prior studies suggest that among men with low grade prostate cancer, African Americans (AA) produce less prostate-specific antigen (PSA) than Caucasians. We investigated racial differences in PSA, PSA density (PSAD), and tumor volume among men with prostate cancer, regardless of tumor grade. These racial differences, if present, would suggest that AA men may benefit from different screening, surveillance, and treatment regiments compared to Caucasians. MATERIALS AND METHODS: We identified men from our institutional prostate cancer database that underwent radical prostatectomy between 2012 and 2015. Clinicopathologic parameters were compared by race. Multivariable linear regression was then performed to identify factors associated with PSA, PSAD, and tumor volume, adjusting for race, age, body mass index, and pathologic parameters. RESULTS: A total of 255 men were included in the analysis, including 182 (71.4%) Caucasian and 73 (28.6%) AA. PSA (10.2 versus 8.1, p = 0.13) and PSAD (0.23 versus 0.22, p = 0.73) did not differ significantly between AA and Caucasian men. In contrast, tumor volume was significantly greater in AA men (13.4 versus 9.6 grams, p = 0.01). In multivariable linear regression analysis, AA race was not associated with PSA (p = 0.80) or PSAD (p = 0.41), but was significantly associated with increased tumor volume (p < 0.01). CONCLUSIONS: AA men who underwent radical prostatectomy in this analysis had larger tumor volume than Caucasian men despite having similar PSA levels. This association suggests that prostate cancers in AA men may produce less PSA than in Caucasian men. These findings have implications for prostate cancer screening and treatment, as PSA may underestimate the presence or extent of cancer in AA men.

Spontaneous passage of ureteral stones in patients with indwelling ureteral stents.

INTRODUCTION: To determine rates of spontaneous ureteral stone passage in patients with indwelling ureteral stents, and to identify factors associated with the spontaneous passage of stones while a ureteral stent is in place. MATERIALS AND METHODS: From our institutional database, we identified patients who underwent ureteroscopic procedures for stone disease between January 1, 2013 and March 1, 2015. We compared the rates of spontaneous stone passage between patients who had previously undergone ureteral stent placement and those who had not. In patients with indwelling stents, multivariate logistic regression was performed to identify factors associated with spontaneous stone passage. RESULTS: A total of 194 patients met inclusion criteria. Spontaneous stone passage rates were similar in the stented (17/119, 14%) and non-stented (15/75, 20%) groups (p = 0.30). In bivariate analysis of stented patients, smaller stone size (p < 0.001) and distal stone location (p = 0.01) were significantly associated with spontaneous stone passage. Multivariate logistic regression analysis of stented patients showed that only small stone size was significantly associated with the likelihood of stone passage (p = 0.01), whereas stent duration, stone location, and stone laterality were not. CONCLUSIONS: A small, but clinically significant percentage of ureteral stones pass spontaneously with a ureteral stent in place. Small stone size is associated with an increased likelihood of spontaneous passage in patients with indwelling stents. These findings may help to identify patients who can potentially avoid additional surgical procedures for definitive stone removal after ureteral stent placement.

Do Ultrasensitive Prostate Specific Antigen Measurements Have a Role in Predicting Long-Term Biochemical Recurrence-Free Survival in Men after Radical Prostatectomy?

PURPOSE: In this study we evaluate an ultrasensitive prostate specific antigen assay in patients with prostate cancer after radical prostatectomy to predict long-term biochemical recurrence-free survival. MATERIALS AND METHODS: A total of 754 men who underwent radical prostatectomy and had an undetectable prostate specific antigen after surgery (less than 0.1 ng/ml) were studied. Prostate specific antigen was measured in banked serum specimens with an ultrasensitive assay (Hybritech® PSA, Beckman Coulter Access® 2) using a cutoff of 0.01 ng/ml. Prostate specific antigen was also measured in 44 men after cystoprostatectomy who had no pathological evidence of prostate cancer with the Hybritech assay and with the Quanterix AccuPSA™ assay. RESULTS: Of the 754 men 17% (131) experienced biochemical recurrence (median 4.0 years). Those men without biochemical recurrence (83%, 623) had a minimum of 5 years of followup (median 11). Prostate specific antigen was less than 0.01 ng/ml in 93.4% of men with no biochemical recurrence, whereas 30.5% of men with biochemical recurrence had a prostate specific antigen of 0.01 ng/ml or greater. On multivariate analysis postoperative prostate specific antigen at a 0.01 ng/ml cutoff, pathological stage and Gleason score, and surgical margins were significant independent predictors of biochemical recurrence risk. Kaplan-Meier estimates for mean biochemical recurrence-free survival were 15.2 years (95% CI 14.9-15.6) for prostate specific antigen less than 0.01 ng/ml and 10.0 years (95% CI 8.4-11.5) for prostate specific antigen 0.01 ng/ml or greater (p <0.0001). Biochemical recurrence-free rates 11 years after surgery were 86.1% (95% CI 83.2-89.0) for prostate specific antigen less than 0.01 ng/ml and 48.9% (95% CI 37.5-60.3) for prostate specific antigen 0.01 ng/ml or greater (p <0.0001). Prostate specific antigen concentrations in 44 men after cystoprostatectomy were all less than 0.03 ng/ml, with 95.4% less than 0.01 ng/ml. CONCLUSIONS: In men with a serum prostate specific antigen less than 0.1 ng/ml after radical prostatectomy a tenfold lower cutoff (0.01 ng/ml) stratified biochemical recurrence-free survival and was a significant independent predictor of biochemical recurrence, as were pathological features. Prostate specific antigen concentrations in men without pathological evidence of prostate cancer suggest that a higher prostate specific antigen concentration (0.03 ng/ml) in the ultrasensitive range may be needed to define the detection threshold.

Complications of Minimally Invasive Surgery and Their Management.

Minimally invasive surgery, including both traditional laparoscopic and robot-assisted laparoscopic approaches, has increasingly become the standard of care for urologic abdominal and pelvic surgery. This is a comprehensive review of the contemporary literature regarding complications of laparoscopic and robotic urologic surgery. The review highlights pertinent studies with the goal of providing the minimally invasive urologic surgeon with an up-to-date overview of general and procedure-specific complications and their management.

An exploratory analysis of the impact of area-level exposome on geographic disparities in aggressive prostate cancer.

Numbers of aggressive prostate cancer (aPC) cases are rising, but only a few risk factors have been identified. In this study, we introduce a systematic approach to integrate geospatial data into external exposome research using aPC cases from Pennsylvania. We demonstrate the association between several area-level exposome measures across five Social Determinants of Health domains (SDOH) and geographic areas identified as having elevated odds of aPC. Residential locations of Pennsylvania men diagnosed with aPC from 2005 to 2017 were linked to 37 county-/tract-level SDOH exosome measures. Variable reduction processes adopted from neighborhood-wide association study along with Bayesian geoadditive logistic regression were used to identify areas with elevated odds of aPC and exposome factors that significantly attenuated the odds and reduced the size of identified areas. Areas with significantly higher odds of aPC were explained by various SDOH exposome measures, though the extent of the reduction depended on geographic location. Some areas were associated with race (social context), health insurance (access), or tract-level poverty (economics), while others were associated with either county-level water quality or a combination of factors. Area-level exposome measures can guide future patient-level external exposome research and help design targeted interventions to reduce local cancer burden.

Appropriateness of Imaging for Low-Risk Prostate Cancer-Real World Data from the Pennsylvania Urologic Regional Collaboration (PURC).

Imaging for prostate cancer defines the extent of disease. Guidelines recommend against imaging low-risk prostate cancer patients with a computed tomography (CT) scan or bone scan due to the low probability of metastasis. We reviewed imaging performed for men diagnosed with low-risk prostate cancer across the Pennsylvania Urologic Regional Collaborative (PURC), a physician-led data sharing and quality improvement collaborative. The data of 10 practices were queried regarding the imaging performed in men diagnosed with prostate cancer from 2015 to 2022. The cohort included 13,122 patients with 3502 (27%) low-risk, 2364 (18%) favorable intermediate-risk, 3585 (27%) unfavorable intermediate-risk, and 3671 (28%) high-risk prostate cancer, based on the AUA guidelines. Amongst the low-risk patients, imaging utilization included pelvic MRI (59.7%), bone scan (17.8%), CT (16.0%), and PET-based imaging (0.5%). Redundant imaging occurred in 1022 patients (29.2%). There was variability among the PURC sites for imaging used in the low-risk patients, and iterative education reduced the need for CT and bone scans. Approximately 15% of low-risk patients had staging imaging performed using either a CT or bone scan, and redundant imaging occurred in almost one-third of men. Such data underscore the need for continued guideline-based education to optimize the stewardship of resources and reduce unnecessary costs to the healthcare system.

Gender-based Disparity Exists in the Surgical Experience of Female and Male Urology Residents.

OBJECTIVE: To determine if a discrepancy exists in the number and type of cases logged between female and male urology residents. MATERIALS AND METHODS: ACGME case log data from 13 urology residency programs was collected from 2007 to 2020. The number and type of cases for each resident were recorded and correlated with resident gender and year of graduation. The median, 25th and 75th percentiles number of cases were calculated by gender, and then compared between female and male residents using Wilcoxon rank sum test. RESULTS: A total of 473 residents were included in the study, 100 (21%) were female. Female residents completed significantly fewer cases, 2174, compared to male residents, 2273 (P = .038). Analysis by case type revealed male residents completed significantly more general urology (526 vs 571, P = .011) and oncology cases (261 vs 280, P = .026). Additionally, female residents had a 1.3-fold increased odds of logging a case in the assistant role than male residents (95% confidence interval: 1.27-1.34, P < .001). CONCLUSION: Gender-based disparity exists within the urology training of female and male residents. Male residents logged nearly 100 more cases than female residents over 4years, with significant differences in certain case subtypes and resident roles. The ACGME works to provide an equal training environment for all residents. Addressing this finding within individual training programs is critical.

Expanded criteria to identify men eligible for active surveillance of low risk prostate cancer at Johns Hopkins: a preliminary analysis.

PURPOSE: At our institution the eligibility criteria used to enroll patients in active surveillance are clinical stage T1, prostate specific antigen density less than 0.15 ng/ml, biopsy Gleason score 6 or less, 2 or fewer positive biopsy cores and 50% or less involvement of any biopsy core. We hypothesized that these criteria may be excessively strict, precluding many men from active surveillance. MATERIALS AND METHODS: We studied pathological outcomes in men treated with radical prostatectomy between 1995 and 2012 who met 4 or more of the 5 active surveillance criteria. Outcomes included a definition of significant tumor (pathological Gleason 7 or greater, or nonorgan confined). We compared adverse pathology rates between men who met all 5 vs 4 of 5 active surveillance criteria. RESULTS: Of 8,261 men 1,890 (22.9%) met all active surveillance eligibility criteria and 2,133 (25.8%) met 4. Men with values exceeding prostate specific antigen density and biopsy Gleason criteria were at increased risk for adverse pathological outcomes. Clinical stage greater than T1 was not associated with adverse pathological findings. The risk of significant tumors in men with clinical stage T2 lesions, 3 or fewer positive biopsy cores and less than 60% core involvement was comparable to that of men who met all active surveillance criteria. CONCLUSIONS: Prostate specific antigen density greater than 0.15 ng/ml and biopsy Gleason score 7 or greater are strongly associated with adverse pathological findings at radical prostatectomy. Our findings suggest that active surveillance criteria should be expanded to include men with clinical stage T2 lesions and a greater number of positive biopsy cores of low grade. Based on these preliminary findings, we are in the process of reassessing active surveillance eligibility criteria using more detailed pathological analysis.

The Use of Dissemination and Implementation to Improve Multimodal Analgesia in Head and Neck Surgery.

OBJECTIVES: To optimize the delivery of multimodal analgesia to patients undergoing major head and neck oncologic surgeries. METHODS: Pilot study included patients enrolled to receive either scheduled acetaminophen and as-needed opioids (control group) or scheduled acetaminophen, gabapentin, ketorolac, and as-needed opioids (experimental group). RCT, a hybrid type 1 effectiveness-implementation pragmatic trial, was designed to test the effectiveness of the intervention. Arm A received scheduled acetaminophen and as-needed opioids. Arm B received scheduled gabapentin, ketorolac, a regional nerve block at the free tissue donor site, scheduled acetaminophen and as-needed opioids. RESULTS: Pilot: Thirty-one patients undergoing major head and neck surgery were enrolled. Mean MMEs administered in control group (n = 15) was 251.60 mg (SD = 224.57 mg); mean MMEs in Experimental group (n = 16) was 195.78 mg (SD = 131.08 mg), p = 0.401. LOS was 8.0 days in control versus 7.0 days in experimental group (p = 0.054). RCT: Interim analysis for safety and futility was planned during trial's design after 30 patients (n = 14 Arm A, and n = 16 Arm B). Mean MMEs administered were 135.1 mg in Arm A, (SD = 86.0 mg) versus mean MME of 51.3 mg in Arm B (SD = 43.3 mg, (p < 0.05)). Given clear superiority results, the trial was prematurely terminated. Functional pain scores, LOS, and complications were similar between the arms (p > 0.05). Variability of mean MME was compared before and after implementation of the management protocols: SD in RCT#1 was 181.46 mg versus 124.6 mg in RCT#2. CONCLUSION: Multimodal analgesia significantly reduced the need for opioids in patients undergoing major head and neck surgery.
