RESUMO
PURPOSE OF REVIEW: The standard treatment of patients with metastatic prostate cancer is systemic treatment with androgen-deprivation therapy (ADT). The spectrum-based model of metastatic disease includes the presence of an oligometastatic state, an intermediary between localized and widespread metastatic disease, in which radical local treatment might improve systemic control. Our purpose is to review the literature on metastasis-directed therapy in the treatment of oligometastatic prostate cancer. RECENT FINDINGS: Several prospective clinical trials have reported improvements in ADT-free survival and progression-free survival with metastasis-directed therapy of oligometastatic prostate cancer. Retrospective studies have found improvements in oncologic outcomes for patients with oligometastatic prostate cancer undergoing metastasis-directed therapy, and several recent prospective clinical trials have confirmed these results. Advancements in imaging as well as an understanding of the genomics of oligometastatic prostate cancer may allow for better patient selection for metastasis-directed therapy and the potential for cure in selected patients.

PURPOSE: To review non-opioid based protocols in urologic oncologic surgery and describe our institutional methods of eliminating peri-operative opioids. METHODS: A thorough literature review was performed using PUBMED to identify articles pertaining to reducing or eliminating narcotic use in genitourinary cancer surgery. Studies were analyzed pertaining to protocols utilized in genitourinary cancer surgery, major abdominal and/or pelvic non-urologic surgery. RESULTS: Reducing or eliminating peri-operative narcotics should begin with an institutionalized protocol made in conjunction with the anesthesia department. Pre-operative regimens should consist of appropriate counseling, gabapentin, and acetaminophen with or without a non-steroidal anti-inflammatory medications. Prior to incision, a regional block or local anesthetic should be delivered. Anesthesiologists may develop opioid-free protocols for achieving and maintaining general anesthesia. Post-operatively, patients should be on a scheduled regimen of ketorolac, gabapentin, and acetaminophen. CONCLUSION: Eliminating peri-operative narcotic use is feasible for major genitourinary oncologic surgery. Patients not only have improved peri-operative outcomes but also are at significantly reduced risk of developing long-term opioid use. Through the implementation of a non-opioid protocol, urologists are able to best serve their patients while positively contributing to reducing the opioid epidemic.

PURPOSE: Patients harboring high-grade non-muscle-invasive bladder cancer (NMIBC) experience high rates of both recurrence and progression. Currently, few treatment options besides cystectomy exist for this at-risk population, especially those with BCG-unresponsive disease. The purpose of this review is to present the current status and describe future directions of immunotherapy in NMIBC. METHODS: The PubMed and Google Scholar databases were searched for articles pertaining to immunotherapy in NMIBC. Relevant planned and ongoing clinical trials were identified using www.ClinicalTrials.gov . Published randomized control trials, reviews, other retrospective and prospective studies deemed relevant were used in this review paper. RESULTS: Novel immunotherapies used in the treatment of high-grade NMIBC and BCG-unresponsive disease allow patients more options and have the potential to reduce the need for radical cystectomy. Currently, several options target the programmed death 1 (PD-1)/programmed death ligand 1 (PD-L1) axis as this mechanism of immunotherapy has been shown to be effective in several cancers, including bladder, melanoma, and lung cancers. In addition, other immunotherapy options for the treatment of NMIBC include viral gene therapies, interleukin-15 superagonists, small molecule inhibitors of indoleamine (2,3)-dioxygenase 1, and vaccines. CONCLUSIONS: The current landscape of immunotherapy in bladder cancer is rapidly evolving, with much literature pertaining to muscle-invasive and metastatic disease. However, the implementation of these treatment options in high-grade NMIBC may allow patients to avoid life-altering surgery. Reliable biomarkers for response are needed to further select patients who may benefit from such therapies.

Background: Conventional operative insufflation uses a one-way trocar to handle instruments while maintaining pneumoperitoneum. In 2007, the AirSeal® valveless trocar insufflation system was introduced, which maintains stable pneumoperitoneum while continuously evacuating smoke. Although this device has been validated in adult patients, it has not been extensively validated in the pediatric population. Materials and Methods: A retrospective cohort study of pediatric urology patients aged 0 to 21 who underwent laparoscopic pyeloplasty between March 2016 and October 2021 was performed. Intraoperative physiologic parameters, procedure characteristics, postoperative outcomes, and demographics of each patient in whom either AirSeal insufflation system (AIS) or conventional insufflation system (CIS) was utilized were obtained from hospital records. Data were compared across the AIS and CIS cohorts. The primary outcomes were intraoperative anesthetic and physiologic parameters, including end tidal carbon dioxide, oxygen saturation, body temperature, positive inspiratory pressure, systolic blood pressure, and heart rate. Results: There were no significant differences in the anesthetic and physiologic parameters in the AIS and CIS groups. In addition, no differences in demographics, procedural characteristics, or complication rates were found between the cohorts. Conclusion: The AirSeal valveless trocar insufflation system demonstrates comparable intraoperative anesthetic and physiologic outcomes compared to conventional one-way valve insufflation in pediatric laparoscopic pyeloplasty. Certain surgeon-related qualitative metrics are underappreciated in this study, however, including improved visualization with vigorous suctioning and pressure maintenance with frequent instrument exchanges. Surgeon experience may mask the benefits of these characteristics as it pertains to quantitative surgical outcomes such as estimated blood loss, operative time, and perioperative complications.

PURPOSE: Targeted tyrosine kinase inhibitors (TKIs) and immune-checkpoint inhibitors (ICIs) revolutionized the treatment of metastatic renal cell carcinoma (RCC). Efforts to translate these therapies into the adjuvant setting for local and locoregional RCC have been pursued over the past decade. We sought to provide an updated review of the literature regarding adjuvant therapy in RCC, as well as an analysis of patient characteristics that may portend the most favorable responses. MATERIALS AND METHODS: Using PubMed, Google Scholar, and Wiley Online Library, we reviewed articles between 2000 and 2022. Search terms included "tyrosine kinase inhibitors," "adjuvant," "immunotherapy," and "renal cell carcinoma." The articles included were original and published in English. Information on clinical trials was collected from ClinicalTrials.gov, accessed in June 2022. RESULTS: Landmark trials investigating adjuvant vascular endothelial growth factor (VEGF) inhibitors produced conflicting results, with only a single trial of sunitinib (S-TRAC) resulting in US Food and Drug Administration-approval on the basis of a slightly prolonged progression-free survival (PFS). Subsequent meta-analyses failed to show a benefit for adjuvant VEGF inhibitors. Several trials evaluating ICIs are currently ongoing, with pembrolizumab (KEYNOTE-564) earning US Food and Drug Administration-approval for a prolonged PFS, although overall survival data are not yet mature. Preliminary results from other adjuvant ICI trials have been conflicting. CONCLUSION: There remains a lack of clear benefit for the use of adjuvant VEGF inhibitors in local and locoregional RCC. Adjuvant ICI investigations are ongoing, with promising results from KEYNOTE-564. It remains to be seen if PFS is an adequate surrogate end point for overall survival. Selection of patients at greatest risk for recurrence, and identification of those at greatest risk of rare but serious adverse events, may improve outcomes.

BACKGROUND: Enhanced recovery after surgery (ERAS) has significantly decreased the morbidity associated with radical cystectomy. However, infectious complications including sepsis, urinary tract (UTIs), wound (WIs), and intra-abdominal (AIs) infections remain common. OBJECTIVE: To assess whether intracorporeal urinary diversion (ICUD) and antibiogram-directed antimicrobial prophylaxis would decrease infections after robotic-assisted radical cystectomy (RARC). DESIGN, SETTING, AND PARTICIPANTS: A retrospective analysis was performed of a prospectively maintained database of patients undergoing RARC between 2014 and 2022 at a tertiary care institution, identifying two groups based on adherence to a prospectively implemented modified ERAS protocol for RARC: modified-ERAS-ICUD and antibiogram-directed ampicillin-sulbactam, gentamicin, and fluconazole prophylaxis were utilized (from January 2019 to present time), and unmodified-ERAS-extracorporeal urinary diversion (UD) and guideline-recommended cephalosporin-based prophylaxis regimen were utilized (from November 2014 to June 2018). Patients receiving other prophylaxis regimens were excluded. INTERVENTION: ICUD and antibiogram-directed infectious prophylaxis. OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS: The primary outcome was UTIs within 30 and 90 d postoperatively. The secondary outcomes were WIs, AIs, and sepsis within 30 and 90 d postoperatively, and Clostridioides difficile infection (CDI) within 90 d postoperatively. RESULTS AND LIMITATIONS: A total of 396 patients were studied (modified-ERAS: 258 [65.2%], unmodified-ERAS: 138 [34.8%]). UD via a neobladder was more common in the modified-ERAS cohort; all other intercohort demographic differences were not statistically different. Comparing cohorts, modified-ERAS had significantly reduced rates of 30-d (7.8% vs 15.9%, p = 0.027) and 90-d UTIs (11.2% vs 25.4%, p = 0.001), and 30-d WIs (1.2% vs. 8.7%, p < 0.001); neither group had a WI after 30 d. Rates of AIs, sepsis, and CDI did not differ between groups. On multivariate regression, the modified-ERAS protocol correlated with a reduced risk of UTIs and WIs (all p < 0.01). The primary limitation is the retrospective study design. CONCLUSIONS: Utilization of ICUD and antibiogram-based prophylaxis correlates with significantly decreased UTIs and WIs after RARC. PATIENT SUMMARY: In this study of infections after robotic radical cystectomy for bladder cancer, we found that intracorporeal (performed entirely inside the body) urinary diversion and an institution-specific antibiogram-directed antibiotic prophylaxis regimen led to fewer urinary tract infections and wound infections at our institution.
RESUMO
OBJECTIVES: To identify correlates of survival and perioperative outcomes of upper tract urothelial carcinoma (UTUC) patients undergoing open (ORNU), laparoscopic (LRNU), and robotic (RRNU) radical nephroureterectomy (RNU). METHODS: We conducted a retrospective, multicenter study that included non-metastatic UTUC patients who underwent RNU between 1990-2020. Multiple imputation by chained equations was used to impute missing data. Patients were divided into three groups based on their surgical treatment and were adjusted by 1:1:1 propensity score matching (PSM). Survival outcomes per group were estimated for recurrence-free survival (RFS), bladder recurrence-free survival (BRFS), cancer-specific survival (CSS), and overall survival (OS). Perioperative outcomes: Intraoperative blood loss, hospital length of stay (LOS), and overall (OPC) and major postoperative complications (MPCs; defined as Clavien-Dindo > 3) were assessed between groups. RESULTS: Of the 2434 patients included, 756 remained after PSM with 252 in each group. The three groups had similar baseline clinicopathological characteristics. The median follow-up was 32 months. Kaplan-Meier and log-rank tests demonstrated similar RFS, CSS, and OS between groups. BRFS was found to be superior with ORNU. Using multivariable regression analyses, LRNU and RRNU were independently associated with worse BRFS (HR 1.66, 95% CI 1.22-2.28, p = 0.001 and HR 1.73, 95%CI 1.22-2.47, p = 0.002, respectively). LRNU and RRNU were associated with a significantly shorter LOS (beta -1.1, 95% CI -2.2-0.02, p = 0.047 and beta -6.1, 95% CI -7.2-5.0, p < 0.001, respectively) and fewer MPCs (OR 0.5, 95% CI 0.31-0.79, p = 0.003 and OR 0.27, 95% CI 0.16-0.46, p < 0.001, respectively). CONCLUSIONS: In this large international cohort, we demonstrated similar RFS, CSS, and OS among ORNU, LRNU, and RRNU. However, LRNU and RRNU were associated with significantly worse BRFS, but a shorter LOS and fewer MPCs.
RESUMO
PURPOSE: Hospital readmission is associated with adverse outcomes and increased cost, and as such, has been identified as a metric for surgical quality and a target for shifts in health policy. However, the disposition of patients who undergo radical cystectomy for bladder cancer and the association between discharge locations and readmission rates is poorly understood. Understanding the patterns and characteristics of readmission after radical cystectomy will help inform discharge planning and expectations and may have long-term impacts on quality and cost of care delivery. We hypothesize that patients will have varying readmission rates based on their discharge location. MATERIALS AND METHODS: An observational analysis of the Nationwide Readmissions Database was performed for all patients who underwent elective radical cystectomy in 2016 to 2017. The patients were grouped by the following criteria: whether they were discharged home, home with care, or to a facility. Univariate analysis was performed using the Chi-square test for categorical variables and the Kruskal-Wallis test for continuous variables. A multivariable logistic regression was conducted to evaluate if discharge locations impact patient readmissions at 30- and 90-days. RESULTS: The final dataset included 4,947 patients discharged home with care, 2,127 patients discharged to home or self-care, and 1,232 patients discharged to a facility. Discharge to a facility was strongly associated with higher 30-day (OR 1.49, CI 1.26-1.76) and 90-day readmission rates (OR 1.46, CI 1.23-1.74). Additionally, home health care was strongly associated with increased 30-day readmission rates (OR 1.22, CI 1.08-1.37) relative to routine discharge home. CONCLUSIONS: Our analysis suggests that discharge location independently predicts readmission following RC. Further study with more granular patient- and system-level data may aid in identifying structural characteristics and processes that can reduce readmissions and their associated economic impact, while maintaining quality of care delivered.

Background: Measuring quality of care indicators is important for clinicians and decision making in health care to improve patient outcomes. Objective: The primary objective was to identify quality of care indicators for patients with upper tract urothelial carcinoma (UTUC) and to validate these in an international cohort treated with radical nephroureterectomy (RNU). The secondary objective was to assess the factors associated with failure to validate the pentafecta. Design: We performed a retrospective multicenter study of patients treated with RNU for EAU high-risk (HR) UTUC. Outcome measurements and statistical analysis: Five quality indicators were consensually approved, including a negative surgical margin, a complete bladder-cuff resection, the absence of hematological complications, the absence of major complications, and the absence of a 12-month postoperative recurrence. After multiple imputations and propensity-score matching, log-rank tests and a Cox regression were used to assess the survival outcomes. Logistic regression analyses assessed predictors for pentafecta failure. Results: Among the 1718 included patients, 844 (49%) achieved the pentafecta. The median follow-up was 31 months. Patients who achieved the pentafecta had superior 5-year overall- (OS) and cancer-specific survival (CSS) compared to those who did not (68.7 vs. 50.1% and 79.8 vs. 62.7%, respectively, all p < 0.001). On multivariable analyses, achieving the pentafecta was associated with improved recurrence-free survival (RFS), CSS, and OS. No preoperative clinical factors predicted a failure to validate the pentafecta. Conclusions: Establishing quality indicators for UTUC may help define prognosis and improve patient care. We propose a pentafecta quality criteria in RNU patients. Approximately half of the patients evaluated herein reached this endpoint, which in turn was independently associated with survival outcomes. Extended validation is needed.
RESUMO
Bladder cancer remains a common and insidious disease in the United States. There have been several advances in the understanding of the biology of bladder cancer, novel diagnostic tools, improvements in multidisciplinary care pathways, and new therapeutics for advanced disease over the past few decades. Clinical trials have demonstrated efficacy for new treatments in each disease state, but additional work is needed to advance the effectiveness of bladder cancer care. Real world data provide critical information regarding patterns of care, adverse events, and outcomes helping to bridge the efficacy versus effectiveness gap.

BACKGROUND: Radical cystectomy is standard of care and part of a multidisciplinary approach for long-term survival in patients with muscle-invasive bladder cancer (MIBC) or high-grade non-MIBC. Recent data have suggested that anesthetic technique can affect long-term survival and recurrence in patients undergoing cancer related surgery. METHODS: The records of all patients who underwent robot-assisted radical cystectomy for high-risk non-MIBC or MIBC at a single academic institution from 2014 to 2020 were retrospectively reviewed. Patients were grouped according to whether they received total intravenous (TIVA) or volatile inhalation anesthesia (VIA). Univariable and multivariable cox proportional hazards models were used to compare hazard ratios for distant recurrence. Kaplan-Meier recurrence-free survival curves were constructed from the date of surgery to recurrence. RESULTS: A total of 231 patients were included, of which 126 (55%) received TIVA and 105 (45%) received VIA. Distant recurrence occurred in 8.7% and 26.7% of patients who received TIVA and VIA, respectively (P < 0.001). Kaplan-Meier analysis demonstrated significant improvement in distant recurrence-free survival with TIVA (log-rank P < 0.001). Multivariable analysis revealed a significant increase in recurrence risk with VIA (HR: 3.4, 95%CI: 1.5-7.7, P < 0.01) and increasing tumor pathological stage (pT2, pT3, pT4, all P < 0.05). CONCLUSIONS: The use of volatile inhalation anesthetics during robot-assisted radical cystectomy may be associated with an increased risk of distant recurrence. Further studies will be necessary to validate these findings.

PURPOSE: The implementation of robot-assisted radical cystectomy (RARC) with intracorporeal urinary diversion (ICUD) for management of patients with muscle-invasive or high-risk noninvasive bladder cancer has increased in utilization over the last decade. Here, we seek to describe institutional opioid prescription and utilization patterns following implementation of a nonopioid (NOP) perioperative pain management protocol in patients who received RARC with ICUD. MATERIALS AND METHODS: The records of all patients who underwent RARC that utilized a NOP perioperative pain management protocol at a single academic institution from 2016 to 2020 were retrospectively reviewed. Descriptive statistical analyses were performed. For comparison, we included 74 consecutive patients who received the same NOP protocol with extracorporeal urinary diversion (ECUD). RESULTS: A total of 116 patients who received ICUD were included in our analysis. The median operation time for the ICUD group was 305 minutes (interquartile range [IQR]: 262-352). 12.1% (nâ¯=â¯14) of patients who underwent ICUD required narcotics during inpatient hospitalization. For these patients, the median morphine milligram equivalent requirement was 52.0 (IQR: 7.62-157). Additionally, only 12.1% (nâ¯=â¯14) of patients were prescribed opioids postoperatively at discharge. We identified that within 6 months of surgery only 5 (4.3%) patients required a second narcotic prescription. Furthermore, of patients who did not use mu-opioid blockers, a minority experienced postoperative ileus (15.7%, nâ¯=â¯16). 30- and 90-day all Clavien complication rates for patients were 44.8% (nâ¯=â¯52) and 49.1% (nâ¯=â¯57), respectively. Nineteen (16.4%) patients were readmitted within 30 days of discharge, of which none were pain related. When compared to ECUD, patients who received ICUD experienced similar complication and readmission rates. CONCLUSIONS: The implementation of a NOP protocol for patients undergoing RARC with ICUD allows for both decreased postoperative narcotic use and reduced need for narcotic prescriptions at discharge with acceptable complication and readmission rates.

BACKGROUND: One of the major challenges in orthopedics is to develop implants that overcome current postoperative problems such as osteointegration, proper load bearing, and stress shielding. Current implant techniques such as allografts or endoprostheses never reach full bone integration, and the risk of fracture due to stress shielding is a major concern. To overcome this, a novel technique of reverse engineering to create artificial scaffolds was designed and tested. The purpose of the study is to create a new generation of implants that are both biocompatible and biomimetic. METHODS: 3D-printed scaffolds based on physiological trabecular bone patterning were printed. MC3T3 cells were cultured on these scaffolds in osteogenic media, with and without the addition of Calcitonin Receptor Fragment Peptide (CRFP) in order to assess bone formation on the surfaces of the scaffolds. Integrity of these cell-seeded bone-coated scaffolds was tested for their mechanical strength. RESULTS: The results show that cellular proliferation and bone matrix formation are both supported by our 3D-printed scaffolds. The mechanical strength of the scaffolds was enhanced by trabecular patterning in the order of 20% for compression strength and 60% for compressive modulus. Furthermore, cell-seeded trabecular scaffolds modulus increased fourfold when treated with CRFP. CONCLUSION: Upon mineralization, the cell-seeded trabecular implants treated with osteo-inductive agents and pretreated with CRFP showed a significant increase in the compressive modulus. This work will lead to creating 3D structures that can be used in the replacement of not only bone segments, but entire bones.
