Social Vulnerability and Receipt of Neoadjuvant Chemotherapy in Patients Undergoing Radical Cystectomy for Bladder Cancer.

To evaluate the association between a population-level measure of social determinants of health, the Centers for Disease Control and Prevention Social Vulnerability Index (SVI), and receipt of neoadjuvant chemotherapy in patients with muscle-invasive bladder cancer (MIBC) undergoing radical cystectomy. We queried our institutional database for patients with nonmetastatic MIBC treated with radical cystectomy between 2000 and 2022. Patients were assigned an SVI via ZIP code of residence and grouped into quintiles of SVI (i.e. least vulnerable to most vulnerable). Multivariable logistic regression was performed to evaluate the association between SVI and receipt of neoadjuvant chemotherapy, adjusting for age, race, gender, and cancer stage. A sub-analysis was performed to evaluate the association between subthemes of SVI (socioeconomic status, household composition/disability, race/ethnicity/language, and housing/transportation) and receipt of neoadjuvant chemotherapy. Of the 978 patients identified, 490 (50.1%) received neoadjuvant chemotherapy. Patients that received neoadjuvant chemotherapy had a lower SVI, were younger, and had >cT2 stage (all, p<0.05). The most vulnerable patients had lower odds of receiving neoadjuvant chemotherapy (OR 0.61, 0.39 - 0.95) compared to the least vulnerable patients. Analysis of subthemes of SVI demonstrated similar associations by socioeconomic status (OR 0.56, 0.36 - 0.86) and household composition/disability (OR 0.57, 0.33 - 0.99). Adverse social determinants of health, or social vulnerability, is associated with suboptimal and disparate utilization of neoadjuvant chemotherapy in patients with MIBC undergoing radical cystectomy. Strategies for identifying vulnerable populations may allow for more targeted interventions that would improve equity in bladder cancer care.

Long term outcomes and impact on renal function following radical cystectomy.

To assess clinical, oncological outcomes and impact on renal function in patients who underwent the radical cystectomy with pelvic lymphadenectomy for muscle invasive and high risk non-muscle invasive transitional cell carcinoma of urinary bladder without evidence of non-regional lymph nodes and distant metastasis. With curative intent total 156 patients underwent radical cystectomy with pelvic lymphadenectomy from January 2015 to December 2022. Total 132/156 patients had primary transitional cell carcinoma of bladder. Thirty patients, presented with obstructive nephropathy, operated after stabilization of renal function. Pre-operatively and post-operatively eGFR calculated using modified diet in renal disease formula. In present study 114 (86.36%) patients had high grade TCC, 70 (53.02%) patients had organ confined disease. Nodal extension seen in 74 (56.06%) patients. Perioperative mortality noted in 36 (27.2%) patients. The overall survival and recurrence free survival (RFS) over 5 years was 66.67 and 45.45%. RFS was significantly related to pathological stage, nodal status, histological-grade, positivity of surgical margin and time of surgery from diagnosis. Total 92/132 (69.7%) patients had recurrence. Pelvic recurrence in 10/92 (10.87%) whereas 82/92 (89.13%) patients had distant recurrence. Pre-operatively mean creatinine was 2.6 mg/dl and mean eGFR was 38.9 ml/h in patients who presented with obstructive nephropathy after stabilization of renal function. Post-operatively in 46/132 (34.8%) patients had improvement in eGFR while 86/132 (65.2%) patients had deterioration of eGFR over 62 months of median follow up. Radical cystectomy provides good overall survival outcomes. Pre-operative eGFR has significant impact on post-operative renal function in long term.

The prognostic value of perioperative platelet and leukocyte values in patients undergoing radical cystectomy: a prospective long-term cohort study.

Studies assessing the impact of preoperative and first-day postoperative values of leukocytes, thrombocytes, and platelet/leukocyte ratio (PLR) after radical cystectomy (RC) are sparse. We aimed to assess the impact of these factors on long-term survival after RC. An analysis of patients undergoing open RC from 2004 to 2023 at our center was performed. Leukocytosis was defined as ≥8,000 leukocytes/μL and thrombocytosis as ≥400,000 thrombocytes/μL. Similarly, the cutoff for PLR was set at 28. A multivariable Cox regression analysis was performed to assess the role of leukocytosis, thrombocytosis and PLR on long-term survival after RC. For all analyses hazard ratios (HRs) with the corresponding 95% confidence intervals (CIs) were estimated. A total of 1,817 patients with a median age of 70 years (IQR: 62-77) were included. Overall, 804 (44%), 175 (10%), and 1,296 (71%) patients presented with leukocytosis, thrombocytosis, and PLR ≥28 preoperatively. Accordingly, 1,414 (78%), 37 (2%), and 249 (14%) patients presented with leukocytosis, thrombocytosis, and PLR ≥28 on the first day after RC. At a median follow-up of 26 months (IQR: 8-68) after RC, 896 (49%) patients died. In the multivariate Cox regression analysis after adjusting for major perioperative risk factors, only preoperative leukocytosis (HR: 1.3, 95%CI: 1.1-1.6, p=0.01), as well as both preoperative and first-day thrombocytosis (HR: 2.1, 95%CI: 1.5-2.9 and HR: 2.8, 95%CI: 1.6-5.1, p&lt;0.001, accordingly) were associated with worse overall survival. PLR should not be used as a prognostic marker for survival after RC. On the contrary, preoperative leukocytosis, as well as preoperative and first-day thrombocytosis should raise awareness among clinicians performing RC, since they were independently associated with worse survival after RC.

Ninety Days complications rate in patients undergoing radical cystectomy with enhanced recovery protocol

Bladder cancer is a carcinoma of the urothelial, or “umbrella,” cells that line the lumen of the urinary bladder. Technically, urothelial carcinoma includes tumors of the bladder, upper urinary tract (renal pelvis and ureters), and proximal urethra. Bladder cancer accounts for approximately 90% to 95% of urothelial carcinoma; bladder cancer comprises 75% pure urothelial carcinoma and 25% “variant” histology, adding complexity to the management of this disease. Bladder cancer can be categorized in several way, almost all bladder cancers originate in the urothelium, which is a 3- to 7-cell mucosal layer within the muscular bladder. Squamous cell carcinoma of the bladder can involve multiple sites; however, the lateral wall and trigone are more commonly involved by this tumor. All small cell carcinomas of the urinary system identified so far have been located in the urinary bladder, most commonly in the dome and vesical lateral wall. Radical cystectomy is a crucial surgical technique in managing MIBC, high-risk NMIBC, and treatment-refractory NMIBC. Despite a high perioperative mortality rate (5-10%), it now carries a 1-2% mortality rate due to improvements in surgical technique, intensive care medicine evolution, and antibiotic availability.

Migration of double-J ureteral stent in patients with ureteroileal anastomosis stricture undergoing radical cystectomy and orthotopic neobladder: Analysis risk factors of stent migration.

The objective was to evaluate the incidence and degree of double-J ureteral stent (DJUS) migration. Additionally, we aimed to investigate the risk factors associated with stent migration in the orthotopic neobladder group. In this retrospective study, 61 consecutive patients were included; 35 patients (45 DJUS placements) underwent radical cystectomy with orthotopic neobladder and 26 patients (35 DJUS placements) underwent urinary bladder without cystectomy between July 2021 and March 2023. All the patients were treated with a DJUS for ureteric strictures. The technical success rate was 100% in each group. The DJUS migration was significantly higher in the orthotopic neobladder group, with 22 of 45 cases (48.9%), compared to the urinary bladder group, which had 4 of 35 cases (11.4%) (P ≤ .001). Among the patients in the orthotopic neobladder group who experienced DJUS migration, stent dysfunction occurred in 18 cases (81.8%), which was statistically significant (P = .003). Multivariate logistic regression analysis revealed that only the size of the DJUS was significantly and positively associated with migration (odds ratio:10.214, P = .010). DJUS migration can easily occur in patients undergoing radical cystectomy and orthotopic neobladder, and smaller stent sizes are associated with a higher incidence of migration.

Systematic Review: Seventy-Seven Cases of Signet Ring Cell Adenocarcinoma of the Bladder

Background: Signet ring cell adenocarcinoma (SRCC) of the bladder is a rare and aggressive histological subtype of bladder cancer. Due to its infrequency, the understanding of its clinical behaviour, treatment strategies, and outcomes remains limited, being primarily derived from isolated case reports and series. Objective: To systematically review and analyse the available literature on SRCC of the bladder, emphasizing its clinical characteristics, diagnostic approaches, treatment modalities, and outcomes. Material and Methods: A comprehensive search was conducted across PubMed, Embase, and Medline following the PRISMA guidelines, including case reports, case series, observational studies, and clinical trials reporting on bladder SRCC. Results: We included 38 articles reporting on 77 patients, primarily males (79.2%), with a median age of 64 years. The most common presenting symptoms were haematuria (64.8%) and lower urinary tract symptoms (46.3%). All the diagnoses were based on histopathological examination of bladder tissue samples and immunohistochemistry. Mixed histological types of bladder cancer were found in 20.7% of cases, most commonly urothelial carcinoma (61.1%). The treatments varied, with 53.2% of patients undergoing radical cystectomy, 24.7% receiving radiotherapy, and 16.9% receiving chemotherapy. The five-year survival rates were 9.4%. Conclusion: Bladder SRCC presents aggressively, with varied treatment strategies; however, radical cystectomy appears to be the optimal means of surgical management for organ-confined disease. The overall survival rate is low, highlighting the need for further research to understand and manage this rare bladder cancer variant. All patients should undergo evaluation to exclude extravesical primaries. This systematic review contributes to a better understanding of this disease and may guide clinical management strategies.

Perioperative complications and oncological outcomes of open versus robotic-assisted radical cystectomy: a propensity score-matched study.

To conduct a comparative effectiveness analysis between robot-assisted radical cystectomy (RARC) and open approach (ORC). A retrospective cohort study was conducted involving all patients undergoing radical cystectomy and urinary diversion for invasive bladder cancer at our institution from 2010 to 2018. Of a total 296 patients, we matched ORC and RARC cases based on age, BMI, Charlson comorbidity index, pathological TN staging of the tumor, prior radiotherapy, and type of diversion. The perioperative complications and oncological outcomes were compared. Eighty-nine patients were matched in the ORC and RARC groups. The median operative time was longer in RARC group (430min) than that of ORC group (372min) (p = 0.03); however, the median estimated blood loss (EBL) was significantly lower in RARC group (500ml) than that of ORC (700ml) (p < 0.0001). The median length of hospital stay (LOS) was significantly reduced in the RARC group (7days) compared to the ORC group (8days) (p = 0.02). There were no significant differences between both groups in 30- and 90-day postoperative complications (p = 0.3 and p = 0.2, respectively). A total of 68 deaths (38.2%) were observed, of which 36 (40.4%) were in ORC group while 32 (36%) were in RARC group (p = 0.5). The results were comparable in both groups regarding 5-year survival rate and cancer-specific survival (p = 0.3 and p = 0.1, respectively). RARC showed better perioperative outcomes in the form of less EBL and shortened LOS compared to ORC group. However, both RARC and ORC provide similar postoperative oncologic control, in terms of similar positive surgical margins, cancer-specific rates, and 5-year survival rates.

Change in the neutrophil-lymphocyte ratio may predict early recurrence in operated bladder cancer.

Recurrence develops in 50% of operated bladder cancer patients. It is important to detect recurrence in advance, and there is no prognostic reliable biomarker for bladder cancer. The aim of this study is to show that changes in hematological parameters before radiological imaging can predict recurrence. We performed a retrospective cohort study of patients undergoing radical cystectomy for urothelial carcinoma of the bladder identified using our institutional database (2010-2022). Disease-free survival (DFS) was evaluated as relapse or death due to any cause. Kaplan-Meier analysis was used for DFS according to the follow-up period. DFS was calculated in two groups neutrophil-lymphocyte ratio (NLR)<3 and NLR≥3. Log-rank test was used for comparison between groups and p<0.05 was considered statistically significant. In the study, 91 patients were examined. The median age was 61.0 (34-79). 57.1% of the patients were T (1-2) and 42.9% were T (3-4). The lymph node (LN) was negative in 78% and positive in 22%. Median follow-up time and DFS were 53.4 months and 54%, respectively. The median NLR was 2.8 (0.8-8.7). For DFS, there was a significant difference according to age, T stage, and LN status (p: 0.048, 0.019, and 0.040). There was no significant difference in the NLR in terms of DFS at the time of diagnosis (p: 0.654). In follow-ups; While there was no difference in the NLR for DFS 12 months before recurrence (p: 0.231), there was a significant difference 6 months before the relapse and at the time of recurrence (p: 0.023 and 0.031). The change in the NLR before radiological recurrence in bladder cancer is significant in predicting recurrence. Prospective and multi-center research is needed to confirm our findings.

Association of preoperative sarcopenia with the long-term prognosis of patients with bladder cancer undergoing radical cystectomy

PurposeThis retrospective study aimed to assess the correlation between preoperative sarcopenia and long-term oncologic outcomes in patients undergoing radical cystectomy for bladder cancer.MethodsWe included 528 patients who underwent radical cystectomy for bladder cancer between 2000 and 2010 at Asan Medical Center, Seoul, Korea. Preoperative skeletal muscle mass was quantified by analyzing computed tomography images at the third lumbar vertebra. Sarcopenia was defined based on the skeletal muscle index. We evaluated various clinical and pathological factors to analyze the association between sarcopenia and long-term oncologic outcomes.ResultsThe median follow-up time was 104 months. Sarcopenia was identified in 37.9% of the patients. Although no significant differences were observed in traditional pathological factors between the sarcopenic and non-sarcopenic groups, sarcopenia was significantly associated with worse oncologic outcomes. Compared to the non-sarcopenic groups, the sarcopenic group had lower overall survival rates (52.0% vs. 67.1% at 5 years, 35.5% vs. 52.7% at 10 years) and higher cancer-specific mortality (63.3% vs. 74.3% at 5 years, 50.7% vs. 67.4% at 10 years). Multivariable Cox regression analysis demonstrated that sarcopenia was an independent predictor of cancer-specific survival (hazard ratio: 1.49, 95% confidence interval: 1.11–2.01, p = 0.008), alongside body mass index, tumor stage, lymph node metastasis, and lymphovascular invasion.ConclusionSarcopenia was significantly associated with poor cancer-specific survival in patients undergoing radical cystectomy for bladder cancer. Detecting sarcopenia may assist in preoperative risk stratification and long-term management after radical cystectomy.

The Association Between Duration of Antibiotics and Infectious Complications Following Radical Cystectomy: Analysis of the 2019-2021 NSQIP Database

ObjectivesTo identify the impact of the duration of peri-operative antibiotics on infectious complications following radical cystectomy. MethodsThe National Surgical Quality Improvement Project (NSQIP) targeted database was queried for patients undergoing radical cystectomy from 2019-2021. Baseline patient characteristics were collected. Antibiotic duration was classified as <24 hours (short), 24-72 hours (intermediate) or >72 hours (long). Infectious complication data was collected including surgical site infection (SSI), urinary tract infection (UTI), organ space infection, pneumonia, sepsis, and clostridium difficile infection up to 30 days after surgery. Univariate and multivariable analyses were performed to compare duration of antibiotic therapy to infectious outcomes. ResultsOf the 4,363 patients who underwent radical cystectomy, 3,250(74%), 827(19%) and 286(6.6%) received short, intermediate, and long duration of peri-operative antibiotics respectively. Infectious complication occurred in 954(22%) patients, including 227(5.2%) SSI, 280(6.4%) UTI, 268(6.1%) organ space infection, 87(2%) pneumonia, and 378(8.7%) sepsis. Clostridium difficile infection occurred in 89(2%) patients. On multivariable analysis, there was no significant difference in overall infectious complication rates with long duration antibiotics. However, intermediate duration of antibiotics in open surgery was associated with a decreased risk of SSI (OR 0.58; 95%CI 0.37-0.91) compared to those treated with short term antibiotics. ConclusionsDespite guideline recommendations, 26% of patients in this database received >24 hours of peri-operative antibiotics without decreased risk of overall infectious complication. An intermediate course of antibiotics decreased risk of SSI in open surgery compared to the guideline recommend <24-hour course. Greater education regarding antibiotic stewardship and further studies investigating infectious complications are warranted.

Predictors of persistent opioid use in bladder cancer patients undergoing radical cystectomy: A SEER-Medicare analysis

PurposeTo evaluate patient and provider characteristics that predict persistent opioid use following radical cystectomy for bladder cancer including non-opioid naïve patients. MethodsPatients undergoing cystectomy between July 2007 and December 2015 were identified using the SEER-Medicare database. Opioid exposure was identified before and after cystectomy using Medicare Part D data. Multivariable analyses were used to identify predictors of the primary outcomes: persistent opioid use (prescription 3–6 months after surgery) and postoperative opioid prescriptions (within 30 days of surgery). Secondary outcomes included physician prescribing practices and rates of persistent opioid use in their patient cohorts. ResultsA total of 1,774 patients were included; 29% had prior opioid exposure. Compared to opioid-naïve patients, non-opioid naïve patients were more frequently younger, Black, and living in less educated communities. The percentage of persistent postoperative use was 10% overall and 24% in non-opioid naïve patients. Adjusting for patient factors, opioid naïve individuals were less likely to develop persistent use (OR 0.23) while a 50-unit increase in oral morphine equivalent per day prescribed following surgery nearly doubled the likelihood of persistent use (OR 1.98). Practice factors such as hospital size, teaching affiliation, and hospital ownership failed to predict persistent use. 29% of patients filled an opioid prescription postoperatively. Opioid naïve patients (OR 0.13) and those cared for at government hospitals (OR 0.59) were less likely to fill an opioid script along with those residing in the Northeast. Variability between physicians was seen in prescribing practices and rates of persistent use. ConclusionsNon-opioid naïve patients have higher rates of post-operative opioid prescription than opioid-naïve patients. Physician prescribing practices play a role in persistent use, as initial prescription amount predicts persistent use even in non-opioid naïve patients. Significant physician variation in both prescribing practices and rates of persistent use suggest a role for standardizing practices.

Nomogram for predicting postoperative ileus after radical cystectomy and urinary diversion: a retrospective single-center study

Objective To predict the incidence of postoperative ileus in bladder cancer patients after radical cystectomy. Methods We retrospectively analyzed the perioperative data of 452 bladder cancer patients who underwent radical cystectomy with urinary diversion at the Second Hospital of Tianjin Medical University between 2016 and 2021. Univariate and multivariate logistic regression were used to identify the risk factors for postoperative ileus. Finally, a nomogram model was established and verified based on the independent risk factors. Results Our study revealed that 96 patients (21.2%) developed postoperative ileus. Using multivariate logistic regression analysis, we found that the independent risk factors for postoperative ileus after radical cystectomy included age > 65.0 years, high or low body mass index, constipation, hypoalbuminemia, and operative time. We established a nomogram prediction model based on these independent risk factors. Validation by calibration curves, concordance index, and decision curve analysis showed a strong correlation between predicted and actual probabilities of occurrence. Conclusion Our nomogram prediction model provides surgeons with a simple tool to predict the incidence of postoperative ileus in bladder cancer patients undergoing radical cystectomy.

Parastomal Hernia Following Ileal Conduit: Incidence, Risk Factors, and Health-Related Quality of Life.

The purpose of this study was to measure the incidence of parastomal hernia (PH) after radical cystectomy and ileal conduit. Secondary aims were the identification of risk factors for PH and to compare the health-related quality of life (QOL) between patients with and without PH. Retrospective review of medical records combined with cross-sectional administration of the QOL instrument and telephone follow-up. The study sample comprised 219 patients who underwent radical cystectomy and ileal conduit for urothelial cancer between February 2014 and December 2018. The study setting was Peking University First Hospital (Beijing, China). Demographic and pertinent clinical data, including development of PH, were gathered via the retrospective review of medical records. Participants were also asked to complete the traditional Chinese language version of the City of Hope Quality of Life-Ostomy Questionnaire (C-COH). Multiple linear regression analysis was used to identify the effect of PH on C-COH scores. Logistic regression analysis was used to identify risk factors for PH development. At a median follow-up of 34 months (IQR = 21-48), 43 of 219 (19.63%) patients had developed a PH. A body mass index (BMI) indicating overweight (OR = 3.548; 95% CI, 1.562-8.061; P = .002), a prior history of hernia (OR = 5.147; 95% CI, 1.195-22.159; P = .028), and chronic high abdominal pressure postdischarge (CHAP-pd) (OR = 3.197; 95% CI, 1.445-7.075; P = .004) were predictors of PH after operation. There was no significant difference between C-COH scores of patients with or without PH. No significant differences were found when participants with PH were compared to those without PH on 4 factors of the C-COH: physical scores (β= .347, P = .110), psychological scores (β= .316, P = .070), spiritual scores (β=-.125, P = .714), and social scores (β= .054, P = .833). Parastomal hernia is prevalent in patients undergoing radical cystectomy and ileal conduit urinary diversion. Overweight, hernia history, and CHAP-pd were predictors of PH development. No significant differences in QOL were found when patients with PH were compared to those without PH.

Impact of Preoperative Plasma Potassium Levels on Oncological Outcomes, Major Complications, and 30-Day Mortality in Bladder Cancer Patients Undergoing Radical Cystectomy

Introduction and ObjectivesWe examined the impact of preoperative plasma potassium levels (PPLs) on outcomes in patients undergoing radical cystectomy (RC) for urothelial carcinoma of the bladder (UCB), hypothesizing that potassium imbalances might influence outcomes. Patients and MethodsIn this retrospective study, 501 UCB patients undergoing RC from 2009 to 2017 at a tertiary center were analyzed. Blood samples collected a week prior to surgery defined normal and abnormal PPL based on institutional standards. We assessed overall survival (OS), cancer-specific survival (CSS), recurrence-free survival (RFS), postoperative complications, 30-day mortality, and non-organ confined disease. Kaplan-Meier estimates, Cox proportional hazards, logistic regression, and decision curve analyses (DCA) were employed. Results63 (13%) patients had abnormal preoperative PPLs, with 50 (10%) elevated and 13 (2.5%) decreased. In a 59 months median follow-up, 152 (31%) had disease recurrence, 197 (39%) died from any cause, and 119 (24%) from UCB. Multivariable cox regression analyses adjusting for perioperative parameters demonstrated abnormal PPL was associated with worse OS (HR=1.9, P=0.009), CSS (HR=2.8, P<0.001) and RFS (HR=2.1; P=0.007). Elevated preoperative PPLs also demonstrated significant associations with adverse outcomes in OS, CSS, and RFS (all P<0.05). In multivariable logistic regression analyses, abnormal and elevated PPLs were not associated with 30-day mortality, major 30-day postoperative complications, positive nodal disease, pT3/4 stage, and non-organ confined disease (all P>0.05). ConclusionAbnormal and elevated preoperative PPLs correlate with adverse oncologic outcomes in UCB patients treated with RC. Pending external validation, preoperative PPLs might be a cost-effective, easily obtainable supplemental biomarker for enriching accuracy of outcome prediction in this highly variable maladie.

Longitudinal Tumor-informed Circulating Tumor DNA Status Predicts Disease Upstaging and Poor Prognosis for Patients Undergoing Radical Cystectomy

Background and objectiveDecision-making on the use of neoadjuvant and adjuvant treatment for patients with bladder cancer undergoing radical cystectomy (RC) currently depends on assessment of clinical and pathological features, which lack sensitivity. Circulating tumor DNA (ctDNA) has emerged as a possible novel prognostic biomarker in the field. Our aim was to assess whether ctDNA status before RC is predictive of pathological and oncological outcomes. We also evaluated the dynamic changes in ctDNA status after RC in relation to recurrence-free survival (RFS). MethodsWe analyzed data for patients who underwent RC during 2021–2023 for whom prospective tumor-informed ctDNA analyses were conducted before and after RC. RFS was evaluated using the Kaplan-Meier method. Predictors for disease recurrence were assessed using Cox proportional-hazards models. Pathological outcomes associated with detectable ctDNA before RC were assessed in univariable and multivariable regression analyses. Key findings and limitationsWe included 112 patients in the analysis. Median follow-up was 8 mo (interquartile range 4–13). ctDNA was detected before RC in 59 patients (53%) and was associated with poor RFS (log-rank p < 0.0001). Detectable ctDNA before RC was associated with poor outcomes regardless of clinical stage (<cT2 vs ≥cT2) and receipt of neoadjuvant therapy. Multivariable analyses revealed that detectable ctDNA before RC was associated with a higher risk of nodal disease (odds ratio 5.4, 95% confidence interval [CI] 1.9–18.2; p = 0.003) and locally advanced disease (odds ratio 3.6, 95% CI 1.5–9; p = 0.005). Cox regression analyses showed that detectable ctDNA before RC (hazard ratio 4.5, 95% CI 1–19; p = 0.04) and detectable ctDNA at the minimal residual disease window (hazard ratio 9.9, 95% CI 2.6–37; p < 0.001) were predictive of disease recurrence. Conclusions and clinical implicationsDetectable ctDNA before definitive therapy with RC is predictive of nodal involvement, locally advanced disease, and disease recurrence in patients with bladder cancer. ctDNA status holds promise for improving clinical staging and augmenting current decision-making tools. Patient summaryWe found that for patients with bladder cancer undergoing radical cystectomy, a test to show the presence of tumor DNA in blood before surgery was able to predict the risk of disease relapse and adverse pathology. Use of this assay could help in decision-making by clinicians and patients for optimal personalized treatment of this disease.

Cumulative incidence and risk factors for recurrence of upper tract urothelial carcinoma in patients undergoing radical cystectomy

AbstractObjectivesThis study aimed to evaluate the cumulative incidence of upper tract urothelial carcinoma (UTUC) recurrence and identify its risk factors in patients who underwent radical cystectomy (RC).Patients and methodsWe performed RC on 385 patients between September 2002 and February 2020. After excluding 20 patients—13 with simultaneous nephroureterectomy, 6 with distal ureteral stump positivity and 1 with urachal cancer—365 patients were included in the analysis. To predict UTUC recurrence, we examined the cancer extension pattern in cystectomy specimens and categorized them into three types: cancer located only in the bladder (bladder‐only type), cancer extending to the urethra or distal ureter (one‐extension type) and cancer extending to both the urethra and distal ureter (both‐extension type). We determined hazard ratios for UTUC recurrence for each covariate, including this cancer extension pattern.ResultsOf the 365 patients, 60% had the bladder‐only type, 30% had the one‐extension type and 10% had the both‐extension type. During a median follow‐up period of 72 months for survivors, UTUC recurred in 25 of the 365 patients, with cumulative incidences of 3.7% at 5 years and 8.3% at 10 years. The median interval from cystectomy to recurrence was 65 months (interquartile range: 36–92 months). In the multivariate analysis, the extension pattern was a significant predictor of UTUC recurrence. The hazard ratios for UTUC recurrence were 3.12 (95% confidence interval [CI] = 1.15–8.43, p = 0.025) for the one‐extension type and 5.96 (95% CI = 1.98–17.91, p = 0.001) for the both‐extension type compared with the bladder‐only type.ConclusionsThe cancer extension pattern in cystectomy specimens is predictive of UTUC recurrence. A more extensive cancer extension in cystectomy specimens elevates the risk of subsequent UTUC recurrence. Intensive long‐term monitoring is essential, particularly for patients with the both‐extension type.

Efficacy of the Addition of Robot-assisted Radical Cystectomy with Extracorporeal Urinary Diversion after an Enhanced Recovery Protocol.

It is unclear if robotic radical cystectomy with extracorporeal urinary diversion (eRARC) provides additional benefit when performed along with enhanced recovery after surgery (ERAS). We assessed the additional efficacy of eRARC in terms of perioperative outcomes. We retrospectively assessed 143 patients undergoing radical cystectomy with urinary diversion between June 2010 and December 2021 at a single center. The patients were assigned to three groups: open radical cystectomy (ORC) with conventional recovery after surgery (CRAS) [Group A], ORC with ERAS [Group B], and eRARC with ERAS [Group C]. A propensity score-matched analysis was performed to evaluate how ERAS and eRARC affected outcomes respectively. Meanwhile, multivariable analysis was used to detect the predictors of prolonged length of hospital stay (LOS). The median LOS was shorter after ERAS and eRARC. In the propensity score-matched analysis, ERAS was linked to a significantly shorter median LOS (28.0 vs. 20.0 days, P < .001), but eRARC was not associated with a shorter LOS (19.0 vs. 17.5 days, P = .21). Neither ERAS nor eRARC were connected with a reduce in complication rate. Following multivariable analysis, ERAS was found to be independently associated with shorter LOS (OR=0.23, P < .001), but eRARC demonstrated no such correlation (OR=0.29, P = .096). ERAS had strong association with shorter LOS, although eRARC did not contribute to additional efficacy. Neither ERAS nor eRARC decreased the complication rate.

An in-depth analysis on the effects of body composition in patients receiving neoadjuvant chemotherapy for urothelial cell carcinoma

Introduction: Neoadjuvant chemotherapy (NAC) is the standard of care for patients undergoing radical cystectomy (RC) for muscle-invasive bladder cancer (MIBC); however, NAC can be associated with significant side effects and morbidity in some patients. NAC may contribute to sarcopenia, obesity, and the combination of the two. Our study examined the effects of NAC on body composition and the association between body composition and adverse events. Methods: We created a retrospective database of patients with non-metastatic MIBC receiving NAC prior to RC. The change in skeletal muscle index (SMI) and fat mass index (FMI) was calculated using computed tomography (CT) scans done within three months prior to NAC and after the first two cycles. The association between body composition (sarcopenia, obesity, and sarcopenic obesity) and preoperative adverse events was investigated using a multivariable logistic regression. Changes in body composition were calculated using a paired Student’s t-test. Results: A total of 70 patients were included in our study. There was a mean decrease in SMI of 2.2±3.2 cm2/m2. Adiposity and FMI were unchanged by NAC. Sarcopenic obesity was found to be associated with adverse events among patients receiving NAC in the multivariable analysis. There were a total of 637 preoperative complications with grades 1–2 and 33 complications with grades 3–5. Conclusions: Based on our retrospective cohort study, NAC did not affect obesity and FMI, but there was a significant decrease in SMI. Sarcopenic obesity was associated with increased severity of NAC adverse events. As such, the presence of this factor may help predict tolerance of NAC.

Three ultrasound guided plane blocks for perioperative analgesia in patients undergoing radical cystectomy: a randomized clinical trial

Background &amp;objective: Transmuscular quadratus lumborum plane block (QLPB), paravertebral plane block (PVPB), and erector spinae plane block (ESPB) are three regional anesthesia techniques for management of perioperative pain for surgical procedures on the trunk, including thorax and abdomen. We compared the effectiveness of PVPB, QLPB type III (QL3), and ESPB for perioperative analgesia during radical cystectomy performed for bladder cancer.&#x0D; Methodology: This randomized double-blind trial was performed on 120 patients, aged above 18 years, undergoing radical cystectomy under general anesthesia. Individuals were randomly divided into 3 equal groups: ESPB, PVPB, and QLPB. Blocks were performed under ultrasound guidance preoperatively on each side with 30 ml of 0.25% bupivacaine. Time to perform block and time to the first dose of morphine postoperatively, were noted. Intra-operative hemodynamic data, including MAP and heart rate (HR) were noted every 10 min for an hour, and then at 30 min intervals. Postoperatively, MAP and HR were recorded at 0, 2, 6, 12 and 24 hours. The connection between qualitative factors was investigated using the chi-square test and Fisher's exact test. For the purpose of comparing the groups, one-way ANOVA and the Bonferroni correction were used. A two-tailed P value &lt; 0.05 was considered significant.&#x0D; Results: Time to perform block was substantially reduced in ESPB and QL3 groups compared to PVPB group. Time to the first dose of morphine was substantially delayed in the PVPB group than ESPB and QL3 groups. Total 24 h morphine consumption was substantially lower in the PVPB group than ESPB and QL3 groups. Postoperative visual analog scale measurements were substantially lower at 15 min, 30 min, and 12 h in the PVPB group than ESPB and QL3 groups and at 6 h in the ESPB and QL3 groups than in PVPB group. Postoperative mean arterial blood pressure and heart rate measurements were substantially reduced at 0 and 12 h in the PVPB group than in ESPB and QL3 groups and at 6 h in the ESPB and QL3 groups than in PVPB group.&#x0D; Conclusions: The ultrasound guided paravertebral plane block was superior to quadratus lumborum plane block type III and erector spinae plane block in providing more effective analgesia but with higher time to perform block.&#x0D; Abbreviations: ESPB- Erector Spinae Plane Block; PVPB- Paravertebral Plane Block; QLPB- Quadratus Lumborum Plane Block; QL3- Quadratus Lumborum Plane Block Type III&#x0D; Keywords: Paravertebral Plane Block; Quadratus Lumborum Plane Block; Erector Spinae Plane Block; Ultrasound; Radical Cystectomy&#x0D; Citation: Seif NE, El-Kholy MM, Ali AR, Zalat MM, Elshazly M.

Comparison of PIV and Other Immune Inflammation Markers of Oncological and Survival Outcomes in Patients Undergoing Radical Cystectomy

Inflammation is widely acknowledged as a significant characteristic of cancer, playing a substantial function in both the initiation and advancement of cancers. In this research, we planned to compare pan-immune inflammation markers and other well-known markers (systemic immune inflammation index and neutrophil to lymphocyte ratio) to predict prognosis in individuals treated with radical cystectomy for bladder cancer. Methods: In this retrospective analysis, we focused on preoperative PIV, systemic immune inflammation index (SII), and neutrophil–lymphocyte ratio (NLR) in 193 individuals managed with radical cystectomy for bladder cancer between January 2016 and November 2022. Multivariable logistic regression assessments were performed to assess the predictive capabilities of PIV, SII, and NLR for infiltration of lymph nodes (N), aggressive tumor stage (pT3/pT4), and any non-organ limited disease at the time of RC. Multivariable Cox regression analyses were conducted to assess the predictive impact of PIV on Relapse-free survival (RFS), Cancer-specific survival (CSS), and Overall survival (OS). Results: Our individuals were divided into high PIV and low PIV cohorts using the optimal cut-off value (340.96 × 109/L) based on receiver operating characteristic curve analysis for relapse-free survival. In multivariable preoperative logistic regression models, only SII and PIV correlated with the infiltration of lymph nodes, aggressive disease, and any non-organ confined disease. In multivariable Cox regression models considering presurgical clinicopathological variables, a higher PIV was associated with diminished RFS (p = 0.017) and OS (p = 0.029). In addition, in multivariable Cox regression models for postoperative outcomes, a high PIV correlated with both RFS (p = 0.034) and OS (p = 0.048). Conclusions: Our study suggests that PIV and SII are two very similar markers that may serve as independent and significant predictors of aggressive disease and worse survival impacts on individuals undergoing radical cystectomy for bladder neoplasm.
