Review
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.

Review
This study aims to conduct a systematic review of full economic analyses of robotic-assisted surgery (RAS) in adults' thoracic and abdominopelvic indications. Authors used Medline, EMBASE, and PubMed to conduct a systematic review following the preferred reporting items for systematic reviews and meta-analyses (PRISMA) 2020 guidelines. Fully published economic articles in English were included. Methodology and reporting quality were assessed using standardized tools. Majority of studies (28/33) were on oncology procedures. Radical prostatectomy was the most reported procedure (16/33). Twenty-eight studies used quality-adjusted life years, and five used complication rates as outcomes. Nine used primary and 24 studies used secondary data. All studies used modeling. In 81% of studies (27/33), RAS was cost-effective or potentially cost-effective compared to comparator procedures, including radical prostatectomy, nephrectomy, and cystectomy. Societal perspective, longer-term time-horizon, and larger volumes favored RAS. Cost-drivers were length of stay and equipment cost. From societal and payer perspectives, robotic-assisted surgery is a cost-effective strategy for thoracic and abdominopelvic procedures.Clinical trial registration This study is a systematic review with no intervention, not a clinical trial.

Meta-Analysis Review
OBJECTIVE
To critically review the currently available evidence of studies comparing robot-assisted radical cystectomy (RARC) with open radical cystectomy (ORC).
METHODS
A comprehensive review of the literature from Pubmed, Web of Science and Scopus was performed in April 2014. All relevant studies comparing RARC with ORC were included for further screening. A pooled meta-analysis of all comparative studies was performed and publication bias was assessed by a funnel plot.
RESULTS
Nineteen studies were included for the analysis, including a total of 1779 patients (787 patients in the RARC group and 992 patients in the ORC group). Although RARC was associated with longer operative time (p <0.0001), patients in this group might benefit from significantly lower overall perioperative complication rates within 30 days and 90 days (p = 0.005 and 0.0002, respectively), more lymph node yields (p = 0.009), less estimated blood loss (p <0.00001), lower need for perioperative and intraoperative transfusions (p <0.0001 and <0.0001, respectively), and shorter postoperative length of stay (p = 0.0002). There was no difference between two groups regarding positive surgical margin rates (p = 0.19).
CONCLUSIONS
RARC appears to be an efficient alternative to ORC with advantages of less perioperative complications, more lymph node yields, less estimated blood loss, lower need for transfusions, and shorter postoperative length of stay. Further studies should be performed to compare the long-term oncologic outcomes between RARC and ORC.

Meta-Analysis Review
Survival outcomes after radical cystectomy (RC) for bladder cancer (BCa) have not improved in recent decades; nevertheless, RC remains the standard treatment for patients with localized muscle-invasive BCa. Identification of the patients most likely to benefit from RC only versus a combination with systemic therapy versus systemic therapy first/only and bladder-sparing is needed. This systematic review and meta-analysis pools the data from published studies on blood-based biomarkers to help prognosticate disease recurrence after RC. A literature search on PubMed and Scopus was conducted according to the Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) statement. Articles published before November 2022 were screened for eligibility. A meta-analysis was performed on studies investigating the association of the neutrophil-to-lymphocyte ratio (NLR), the only biomarker with sufficient data, with recurrence-free survival. The systematic review identified 33 studies, and 7 articles were included in the meta-analysis. Our results demonstrated a statistically significant correlation between elevated NLR and an increased risk of disease recurrence (HR 1.26; 95% CI 1.09, 1.45; = 0.002) after RC. The systematic review identified various other inflammatory biomarkers, such as interleukin-6 or the albumin-to-globulin ratio, which have been reported to have a prognostic impact on recurrence after RC. Besides that, the nutritional status, factors of angiogenesis and circulating tumor cells, and DNA seem to be promising tools for the prognostication of recurrence after RC. Due to the high heterogeneity between the studies and the different cut-off values of biomarkers, prospective and validation trials with larger sample sizes and standardized cut-off values should be conducted to strengthen the approach in using biomarkers as a tool for risk stratification in clinical decision-making for patients with localized muscle-invasive BCa.

Meta-Analysis Review
PURPOSE
To perform a comprehensive comparison of overall survival (OS), disease-specific survival (DSS), progression-free survival (PFS), and treatment-related complications between radical cystectomy (RC) and combined modality treatment (CMT-radiation therapy, concurrent chemotherapy, and maximal transurethral resection of bladder tumor) in the setting of muscle-invasive bladder cancer.
METHODS AND MATERIALS
We searched 7 databases (PubMed, Scopus, EMBASE, Proquest, CINAHL, and ClinicalTrials.gov) for randomized, controlled trials and prospective and retrospective studies directly comparing RC with CMT from database inception to March 2016. We conducted meta-analyses evaluating OS, DSS, and PFS with hazard ratios (HRs) and 95% confidence intervals (CIs).
RESULTS
Nineteen studies evaluating 12,380 subjects were selected. For the 8 studies encompassing 9554 subjects eligible for meta-analyses, we found no difference in OS at 5 years (HR 0.96, favoring CMT, 95% CI 0.72-1.29; P=.778) or 10 years (HR 1.02, favoring cystectomy, 95% CI 0.73-1.42; P=.905). No difference was observed in DSS at 5 years (HR 0.83, favoring radiation, 95% CI 0.54-1.28; P=.390) or 10 years (HR 1.17, favoring cystectomy, 95% CI 0.89-1.55; P=.264), or PFS at 10 years (HR 0.85, favoring CMT, 95% CI 0.43-1.67; P=.639). The cystectomy arms had higher rates of early major complications, whereas rates of minor complications were similar between the 2 treatments.
CONCLUSION
Current meta-analysis reveals no differences in OS, DSS, or PFS between RC and CMT. Further randomized, controlled trials are necessary to identify the optimal treatment for specific patients.

Frontiers in Oncology 2023Panurothelial carcinoma is a rare and aggressive malignancy that requires effective treatment strategies to enhance patient outcomes.
BACKGROUND
Panurothelial carcinoma is a rare and aggressive malignancy that requires effective treatment strategies to enhance patient outcomes.
METHODS
We conducted a systematic search of English publications in databases including PubMed, Embase, Cochrane Library, and Web of Science up to May 2023. The quality of the literature was assessed using the Newcastle-Ottawa Scale (NOS) and the Methodological Quality and Synthesis of Case Series and Case Reports tool. Data statistics and analysis were performed using Stata 15.1 software (StataSE, USA).
RESULTS
Six studies involving 339 patients were included in the analysis. Meta-analysis revealed that Simultaneous Radical Cystectomy and Nephroureterectomy had 2-year and 5-year overall survival rates of 68% (95% CI 60%-76%, I = 12.4%, P < 0.001) and 44% (95% CI 36%-53%, I = 0, P < 0.001), respectively. The 2-year and 5-year progression-free survival rates were 91% (95% CI 86%-95%, I = 95%, P < 0.001) and 65% (95% CI 58%-73%, I = 91.5%, P < 0.001), respectively. The 2-year and 5-year cancer-specific survival rates were 73% (95% CI 66%-81%, I = 16.7%, P < 0.001) and 57% (95% CI 49%-66%, I = 0, P < 0.001), respectively. Additionally, the incidence of minor complications was 19% (95% CI 15%-23%, P < 0.01), major complications was 49% (95% CI 34%-63%, P < 0.01), and the intraoperative blood transfusion rate was 53% (95% CI 44%-61%, P < 0.01).
CONCLUSIONS
Simultaneous radical cystectomy and nephroureterectomy represent feasible approaches for the treatment of Panurothelial carcinoma. Nonetheless, a comprehensive assessment of the surgical risks and benefits is imperative, and larger-scale prospective cohort studies are required to validate therapeutic efficacy.

Review
OBJECTIVES
To examine patient and clinicopathological features of malignant urachal neoplasms (MUN) in a population-based cohort, to investigate survival outcomes, and to review the current evidence that exists in the literature.
MATERIAL AND METHODS
The Surveillance, Epidemiology, and End Results database was used to identify microscopically confirmed MUN cases diagnosed between 1988 and 2012. Kaplan-Meier analysis was used to determine median and 5-year overall survival (OS) as well as cancer-specific survival (CSS) rates. Cox proportional hazards model was employed to identify variables independently associated with cancer-specific mortality. A systematic literature review was conducted in line with the PRISMA statement.
RESULTS
A total of 420 patients with MUNs were identified. The majority were white (77.6%) and male patients (59%) who presented with low-grade (62.1%), mucinous, noncystic adenocarcinomas (42.9%). From the cohort, 19%, 15.2%, 29.5%, and 30.5% of the patients presented with American Joint Committee on Cancer Stage I to IV disease, respectively. Cancer-directed surgery was performed in 86.5% of the patients. The most common procedure performed was partial cystectomy (52.4%) followed by local tumor excision (20.7%). Median OS was 57 months (95% CI: 41.6-72.4), and median CSS was 105 months (95% CI: 61.5-148.5). Five-year OS and CSS rates were 51% and 57%, respectively. Grade and stage were independently associated with cancer-specific mortality. Mortality rates did not differ between patients who underwent partial cystectomy and radical cystectomy/exenteration (P = 0.165), even after controlling for tumor stage. A total of 16 studies reporting on 585 patients were systematically reviewed, and relevant outcomes were summarized in the Supplemental material.
CONCLUSIONS
MUNs are usually low-grade, mucinous, noncystic adenocarcinomas diagnosed at advanced stages. Overall, the prognosis is poor, and high-grade and disease stage are independently associated with cancer-specific mortality.

Meta-Analysis
CONTEXT
The complexity of bladder cancer diagnosis and staging results in delays in definitive treatment of muscle-invasive bladder cancer by radical cystectomy.
OBJECTIVE
This systematic review and meta-analyses aim to assess the impact of delays in radical cystectomy.
EVIDENCE ACQUISITION
A systematic review was conducted by searching Medline and Ovid Gateway using protocol-driven search terms in August 2019, with no time limit on the studies included. The identified studies were assessed according to strict criteria and using the Strengthening the Reporting of Observational Studies in Epidemiology (STROBE) checklist and Risk of Bias in Non-randomised Studies-of Interventions (ROBINS-I) tool. Meta-analyses were conducted based on the type of delay. Random-effect models were used whereby the presence of a delay was the exposure variable and overall survival was the outcome of interest, for which pooled hazard ratios were calculated.
EVIDENCE SYNTHESIS
Nineteen studies were eligible for inclusion (17 532 patients), of which 10 were included in the meta-analyses. A longer delay between bladder cancer diagnosis and radical cystectomy resulted in a pooled hazard ratio of 1.34 (95% confidence interval [CI]: 1.18-1.53) for overall death. For a delay between transurethral resection and cystectomy, we found a pooled hazard ratio of 1.18 (95% CI: 0.99-1.41) for overall death. A pooled hazard ratio of 1.04 (95% CI: 0.93-1.16) was calculated for a longer delay between neoadjuvant chemotherapy and radical cystectomy.
CONCLUSIONS
A delay in radical cystectomy after diagnosis was found to have a significantly detrimental effect on overall survival for bladder cancer patients. However, there was huge heterogeneity in how a delay was defined.
PATIENT SUMMARY
In this review, we investigated the effect of a delay in radical treatment on survival. This review highlights the importance of scheduling radical cystectomies in a timely manner whilst monitoring factors such as comorbidities and scheduling, in order to treat patients requiring radical cystectomy without delay.

Review
OBJECTIVES
To determine and summarize the available data on urinary, sexual, and health-related quality-of-life (HRQOL) outcomes after traditional radical cystectomy (RC), reproductive organ-preserving RC (ROPRC) and nerve-sparing RC (NSRC) for bladder cancer (BCa) in female patients.
METHODS
The PubMed, SCOPUS and Web of Science databases were searched to identify studies reporting functional outcomes in female patients undergoing RC and urinary diversion for the treatment of BCa. The outcomes of interest were voiding function (for orthotopic neobladder [ONB]), sexual function and HRQOL. The following independent variables were derived and included in the meta-analysis: pooled rate of daytime and nighttime continence/incontinence, and intermittent self-catheterization (ISC) rates. Analyses were performed separately for traditional, organ- and/or nerve-sparing surgical approaches.
RESULTS
Fifty-three studies comprising 2740 female patients (1201 traditional RC and 1539 organ-/nerve-sparing RC, and 264 nerve-sparing-alone RC) were eligible for qualitative synthesis; 44 studies comprising 2418 female patients were included in the quantitative synthesis. In women with ONB diversion, the pooled rates of daytime continence after traditional RC, ROPRC and NSRC were 75.2%, 79.3% and 71.2%, respectively. The pooled rate of nighttime continence after traditional RC was 59.5%; this rate increased to 70.7% and 71.7% in women who underwent ROPRC and NSRC, respectively. The pooled rate of ISC after traditional RC with ONB diversion in female patients was 27.6% and decreased to 20.6% and 16.8% in patients undergoing ROPRC and NSRC, respectively. The use of different definitions and questionnaires in the assessment of postoperative sexual and HRQOL outcomes did not allow a systematic comparison.
CONCLUSIONS
Female organ- and nerve-sparing surgical approaches during RC seem to result in improved voiding function. There is a significant need for well-designed studies exploring sexual and HRQOL outcomes to establish evidence-based management strategies to support a shared decision-making process tailored towards patient expectations and satisfaction. Understanding expected functional, sexual and quality-of-life outcomes is necessary to allow individualized pre- and postoperative counselling and care delivery in female patients planned to undergo RC.

Review
BACKGROUND
Our understanding of effective perioperative supportive interventions for patients undergoing cystectomy procedures and how these may affect short and long-term health outcomes is limited.
METHODS
Randomised controlled trials involving any non-surgical, perioperative interventions designed to support or improve the patient experience for patients undergoing cystectomy procedures were reviewed. Comparison groups included those exposed to usual clinical care or standard procedure. Studies were excluded if they involved surgical procedure only, involved bowel preparation only or involved an alternative therapy such as aromatherapy. Any short and long-term outcomes reflecting the patient experience or related urological health outcomes were considered.
RESULTS
Nineteen articles (representing 15 individual studies) were included for review. Heterogeneity in interventions and outcomes across studies meant meta-analyses were not possible. Participants were all patients with bladder cancer and interventions were delivered over different stages of the perioperative period. The overall quality of evidence and reporting was low and outcomes were predominantly measured in the short-term. However, the findings show potential for exercise therapy, pharmaceuticals, ERAS protocols, psychological/educational programmes, chewing gum and nutrition to benefit a broad range of physiological and psychological health outcomes.
CONCLUSIONS
Supportive interventions to date have taken many different forms with a range of potentially meaningful physiological and psychological health outcomes for cystectomy patients. Questions remain as to what magnitude of short-term health improvements would lead to clinically relevant changes in the overall patient experience of surgery and long-term recovery.
