Reliability, validity, and change thresholds of the NCCN/FACT Bladder Symptom Index (NFBlSI-18) in patients with advanced urothelial cancer.

BACKGROUND: The NCCN/FACT Bladder Symptom Index-18 (NFBlSI-18) is a bladder cancer-specific instrument. We aimed to psychometrically evaluate the reliability and validity of NFBlSI-18 and estimate change thresholds for total, disease-related symptoms-physical (DRS-P), DRS-emotional (DRS-E), and function/well-being (F/WB) scales in patients with locally advanced/metastatic urothelial cancer (la/mUC). METHODS: JAVELIN Bladder 100 trial data were analyzed. Anchors to evaluate validity included: 5-level EuroQoL-5D utility index (EQ-5D-5L UI), visual analog scale (VAS), Eastern Cooperative Oncology Group (ECOG) performance status, and number of symptoms. Responsiveness to change was tested by anchoring to time to tumor progression (TTP), best overall response (BOR), and differences in means between ECOG categories to estimate meaningful between-group differences. Meaningful within-group change thresholds were estimated using receiver operating characteristic curve analysis, anchoring to change in EQ-5D-5L UI. Significant within-individual patient change thresholds were estimated with reliable and likely change indexes. RESULTS: Correlations with EQ-5D-5L UI and VAS ranged from 0.53 to 0.73. Standardized effect sizes were >0.20. Compared with patients with TTP of ≥6 months, patients with TTP of >0-2 and 3-5 months had larger declines; results for BOR were similar. Thresholds (points) for meaningful between-group differences were: total, 6-11; DRS-P, 3-6; and DRS-E and F/WB, 1. Thresholds (points) for meaningful within-group worsening were: total, 4; and DRS-P, 3, and for significant individual change they were: total, 3-9; DRS-P, 2-6; DRS-E, 1-3; and F/WB, 2-4. CONCLUSIONS: NFBlSI-18 exhibited evidence of reliability, validity, and responsiveness to assess quality of life in studies of la/mUC, and change thresholds are established for future studies. PLAIN LANGUAGE SUMMARY: The NCCN/FACT Bladder Symptom Index-18 (NFBlSI-18) is a questionnaire used to assess quality of life for people with advanced bladder cancer. People with advanced bladder cancer who took part in the JAVELIN Bladder 100 study completed the NFBlSI-18 when they joined the study and after each treatment with avelumab maintenance or best supportive care. This study showed that NFBlSI-18 is suitable for capturing bladder cancer symptoms and is able to detect important changes in a person's quality of life over time. This study also provides thresholds for changes in NFBlSI-18 scores, which will be useful for future studies.

Reevaluating the role of platinum-based chemotherapy in the evolving treatment landscape for patients with advanced urothelial carcinoma.

Platinum-based chemotherapy has been the standard first-line (1L) treatment for advanced urothelial carcinoma (UC) for decades, based on the proven efficacy and established safety profiles of cisplatin- and carboplatin-based regimens. With the emergence of novel regimens, it is important to reevaluate and contextualize the role of 1L platinum-based chemotherapy. Platinum-based chemotherapy followed by avelumab 1L maintenance in patients without disease progression following platinum-based chemotherapy was established as a standard 1L regimen based on the JAVELIN Bladder 100 phase III trial. More recently, the EV-302 phase III trial showed the superiority of 1L enfortumab vedotin (EV) + pembrolizumab versus platinum-based chemotherapy, and the Checkmate 901 phase III trial showed the superiority of 1L nivolumab + cisplatin/gemcitabine versus cisplatin/gemcitabine alone. These 2 regimens have now been included as standard 1L options in treatment guidelines for advanced UC. EV + pembrolizumab is now the preferred 1L treatment, and in locations where EV + pembrolizumab is not available or individual patients are not considered suitable, recommended options are platinum-based chemotherapy followed by avelumab maintenance or nivolumab + cisplatin-based chemotherapy. In this review, we discuss current treatment options for advanced UC recommended in guidelines, practical considerations with platinum-based chemotherapy, the role of avelumab 1L maintenance, recent phase III trials of EV + pembrolizumab and nivolumab + cisplatin/gemcitabine, safety profiles of recommended 1L treatments, and second-line treatment options.

Treatment of Non-Metastatic Muscle-Invasive Bladder Cancer: AUA/ASCO/SUO Guideline (2017; Amended 2020, 2024).

PURPOSE: Although representing approximately 25% of patients diagnosed with bladder cancer, muscle-invasive bladder cancer (MIBC) carries a significant risk of death that has not significantly changed in decades. Increasingly, clinicians and patients recognize the importance of multidisciplinary collaborative efforts that take into account survival and quality of life concerns. This guideline provides a risk-stratified, clinical framework for the management of muscle-invasive urothelial bladder cancer. METHODOLOGY/METHODS: In 2024, the MIBC guideline was updated through the AUA amendment process in which newly published literature is reviewed and integrated into previously published guidelines in an effort to maintain currency. The amendment allowed for the incorporation of additional literature released since the previous 2020 amendment. The updated search gathered literature from May 2020 to November 2023. This review identified 3739 abstracts, of which 46 met inclusion criteria.When sufficient evidence existed, the body of evidence was assigned a strength rating of A (high), B (moderate), or C (low) for support of Strong, Moderate, or Conditional Recommendations. In the absence of sufficient evidence, additional information is provided as Clinical Principles and Expert Opinions. RESULTS: Updates were made regarding neoadjuvant/adjuvant chemotherapy, radical cystectomy, pelvic lymphadenectomy, multi-modal bladder preserving therapy, and future directions. Further revisions were made to the methodology and reference sections as appropriate. CONCLUSIONS: This guideline seeks to improve clinicians' ability to evaluate and treat patients with MIBC based on currently available evidence. Future studies will be essential to further support or refine these statements to improve patient care.

Feasibility, Acceptability, and Outcomes of a Mobile Health Tool for Radical Cystectomy Recovery.

PURPOSE: Postoperative education and symptom tracking are essential following cystectomy to reduce readmission rates and information overload. To address these issues, an internet-based tool was developed to provide education, alerts, and symptom tracking. We aimed to evaluate the tool's feasibility, acceptability, and impact on complication and readmission rates. MATERIALS AND METHODS: Thirty-three eligible patients over 18 years old scheduled for cystectomy were enrolled. Patients were asked to use the mobile health (mHealth) tool daily for the first 2 weeks, then less frequently up to 90 days after discharge. Descriptive statistics were used to summarize study variables. Feasibility was defined as at least 50% of patients using the tool once a week, and acceptability as patient satisfaction of > 75%. RESULTS: Use of the mHealth tool was feasible, with 90% of patients using it 1 week after discharge, but engagement declined over time to 50%, with technological difficulties being the main reason for nonengagement. Patient and provider acceptability was high, with satisfaction > 90%. Within 90 days, 36% experienced complications after discharge and 30% were readmitted. Engagement with the mHealth application varied but was not statistically associated with readmission (P = .21). CONCLUSIONS: The study showed that the electronic mobile health intervention for patients undergoing cystectomy was feasible, acceptable, and provided valuable educational content and symptom management. Future larger studies are needed to determine the tool's effectiveness in improving patient outcomes and its potential implementation into routine clinical care.

A Proposal for Standardization of Early Outcomes Following Robot-Assisted Radical Cystectomy (RARC): RARC Tetrafecta.

BACKGROUND: Currently, there is no dedicated tool to record the early outcomes of robot-assisted radical cystectomy (RARC), and existing criteria for longer-term outcomes require a minimum of 3 months for assessment. However, early evaluation is essential to prevent future morbidity and mortality, especially in surgeries with a high risk of complications in the short term. We propose a comprehensive approach to report early RARC outcomes and investigate the influence of surgeon experience on these results. PATIENTS AND METHODS: We retrospectively analyzed the outcomes of patients who underwent RARC for bladder cancer between April 2009 and April 2020. The cohort was divided chronologically into three groups: patients 1-60 in group 1, 61-120 in group 2, and 121-192 in group 3. Patients with yields of ≥ 16 lymph nodes (LN), negative soft tissue surgical margins, absence of transfusion, and absence of major complications at 30 days were regarded as attaining the RARC tetrafecta. RESULTS: Of the 192 included patients, 93 (48.4%) achieved RARC tetrafecta, with the proportion increasing with surgical experience from 41.7% in group 1 to 55.6% in group 3. Age [odds ratio (OR) 0.947; 95% confidence interval (CI) 0.924-0.970; P = 0.021], LN yield (OR 1.432; 95% CI 1.139-1.867; P = 0.001), and greater surgical experience with RARC (> 120 patients; OR 2.740; 95% CI 1.231-6.100; P = 0.014) were significantly associated with the achievement of RARC tetrafecta. CONCLUSIONS: RARC tetrafecta could be a comprehensive method for reporting early outcomes in patients undergoing RARC, with improvements aligned with the surgeon's experience.

Immune checkpoint gene signature assesses immune infiltration profiles in bladder cancer and identifies KRT23 as an immunotherapeutic target.

BACKGROUND: In the past few decades, researchers have made promising progress, including the development of immune checkpoint inhibitors (ICIs) in the therapy of bladder cancer (BLCA). Existing studies mainly focus on single immune checkpoint inhibitors but lack relevant studies on the gene expression profiles of multiple immune checkpoints. METHODS: RNA-sequencing profiling data and clinical information of BLCA patients and normal human bladder samples were acquired from the Cancer Genome Atlas and Gene Expression Omnibus databases and analyzed to identify different expression profiles of immune checkpoint genes (ICGs) after consensus clustering analysis. Based on the 526 intersecting differentially expressed genes, the LASSO Cox regression analysis was utilized to construct the ICG signature. RESULTS: According to the expression of ICGs, BLCA patients were divided into three subtypes with different phenotypic and mechanistic characteristics. Furthermore, the developed ICG signature were independent predictors of outcome in BLCA patients, and was correlated with the immune infiltration, the expression of ICGs and chemotherapeutic effect. CONCLUSIONS: This study systematically and comprehensively analyzed the expression profile of immune checkpoint genes, and established the ICG signature to investigate the differences in ICGs expression and tumor immune microenvironment, which will help risk stratification and accelerate precision medicine. Finally, we identified KRT23 as the most critical model gene, and highlighted KRT23 as a potential target to enhance immunotherapy against BLCA.

The optimal number of induction chemotherapy cycles in clinically lymph node-positive bladder cancer.

OBJECTIVE: To investigate the optimal number of induction chemotherapy cycles needed to achieve a pathological response in patients with clinically lymph node-positive (cN+) bladder cancer (BCa) who received three or four cycles of induction chemotherapy followed by consolidative radical cystectomy (RC) with pelvic lymph node dissection. PATIENTS AND METHODS: We included 388 patients who received three or four cycles of cisplatin/gemcitabine or (dose-dense) methotrexate, vinblastine, doxorubicin, and cisplatin (MVAC), followed by consolidative RC for cTanyN1-3M0 BCa. We compared pathological complete (pCR = ypT0N0) and objective response (pOR = yp ≤T1N0) between treatment groups. Predictors of pCR and/or pOR were assessed using uni- and multivariable logistic regression analysis. The secondary endpoints were overall (OS) and cancer-specific survival (CSS). We evaluated the association between the number of induction chemotherapy cycles administered and survival outcomes on multivariable Cox regression. RESULTS: Overall, 101 and 287 patients received three or four cycles of induction chemotherapy, respectively. Of these, 72 (19%) and 128 (33%) achieved pCR and pOR response, respectively. The pCR (20%, 18%) and pOR (40%, 31%) rates did not differ significantly between patients receiving three or four cycles (P > 0.05). The number of cycles was not associated with pCR or pOR on multivariable logistic regression analyses. The 2-year OS estimates were 63% (95% confidence interval [CI] 0.53-0.74) and 63% (95% CI 0.58-0.7) for patients receiving three or four cycles, respectively. Receiving three vs four cycles was not associated with OS and CSS on uni- or multivariable Cox regression analyses. CONCLUSION: Pathological response and survival outcomes did not differ between administering three or four induction chemotherapy cycles in patients with cN+ BCa. A fewer cycles (minimum three) may be oncologically sufficient in patients with cN+ BCa, while decreasing the wait for definitive local therapy in those patients who end up without a response to chemotherapy. This warrants further validation.

Impact of the extent of lymph node dissection on survival outcomes in clinically lymph node-positive bladder cancer.

OBJECTIVE: To determine the oncological impact of extended pelvic lymph node dissection (ePLND) vs standard PLND (sPLND) during radical cystectomy (RC) in clinically lymph node-positive (cN+) bladder cancer (BCa). PATIENTS AND METHODS: In this retrospective, multicentre study we included 969 patients who underwent RC with sPLND (internal/external iliac and obturator lymph nodes) or ePLND (sPLND plus common iliac and presacral nodes) with or without platin-based peri-operative chemotherapy for cTany N1-3 M0 BCa between 1991 and 2022. We assessed the impact of ePLND on recurrence-free survival (RFS) and the distribution of recurrences (locoregional and distant recurrences). The secondary endpoint was overall survival (OS). We performed propensity-score matching using covariates associated with the extent of PLND in univariable logistic regression analysis. The association of the extent of PLND with RFS and OS was investigated using Cox regression models. RESULTS: Of 969 cN+ patients, 510 were 1:1 matched on propensity scores. The median (interquartile range [IQR]) time to recurrence was 8 (4-16) months, and median (IQR) follow-up of alive patients was 30 (13-51) months. Disease recurrence was observed in 104 patients in the ePLND and 107 in the sPLND group. Of these, 136 (27%), 47 (9.2%) and 19 patients (3.7%) experienced distant, locoregional, or both distant and locoregional disease recurrence, respectively. When stratified by the extent of PLND, we did not find a difference in recurrence patterns (P > 0.05). ePLND improved neither RFS (hazard ratio [HR] 0.91, 95% confidence interval [CI] 0.70-1.19; P = 0.5) nor OS (HR 0.78, 95% CI 0.60-1.01; P = 0.06) compared to sPLND. Stratification by induction chemotherapy did not change outcomes. CONCLUSION: Performing an ePLND at the time of RC in cN+ patients improved neither RFS nor OS compared to sPLND, regardless of induction chemotherapy status. Pretreatment risk stratification is paramount to identify ideal candidates for RC with ePLND as part of a multimodal treatment approach.

Trimodal therapy vs radical cystectomy in patients with muscle-invasive bladder cancer: a systematic review and meta-analysis of comparative studies.

OBJECTIVE: To perform a systematic review and meta-analysis of trials comparing trimodal therapy (TMT) and radical cystectomy (RC), evaluating differences in terms of oncological outcomes, quality of life, and costs. MATERIALS AND METHODS: In July 2023, a literature search of multiple databases was conducted to identify studies analysing patients with cT2-4 N any M0 muscle-invasive bladder cancer (MIBC; Patients) receiving TMT (Intervention) compared to RC (Comparison), to evaluate survival outcomes, recurrence rates, costs, and quality of life (Outcomes). The primary outcome was overall survival (OS). Secondary outcomes were cancer-specific survival (CSS) and metastasis-free survival (MFS). Hazard ratios (HRs) were used to analyse survival outcomes according to different treatment modalities and odds ratios were used to evaluate the likelihood of receiving each type of treatment according to T stage. RESULTS: No significant difference in terms of OS was observed between RC and TMT (HR 1.07, 95% confidence interval [CI] 0.81-1.4; P = 0.6), even when analysing radiation therapy regimens ≥60 Gy (HR 1.02, 95% CI 0.69-1.52; P = 0.9). No significant difference was observed in CSS (HR 1.12, 95% CI 0.79-1.57, P = 0.5) or MFS (HR 0.88, 95% CI 0.66-1.16; P = 0.3). The mean cost of TMT was significantly higher than that of RC ($289 142 vs $148 757; P < 0.001), with greater effectiveness in terms of cost per quality-adjusted life-year. TMT ensured significantly higher general quality-of-life scores. CONCLUSION: Trimodal therapy appeared to yield comparable oncological outcomes to RC concerning OS, CSS and MFS, while providing superior patient quality of life and cost effectiveness.

Robotic-assisted radical cystectomy with cutaneous ureterostomies: a contemporary multicenter analysis.

BACKGROUND: Robotic-assisted radical cystectomy (RARC) offers decreased blood loss during surgery, shorter hospital length of stay, and lower risk for thromboembolic events without hindering oncological outcomes. Cutaneous ureterostomies (UCS) are a seldom utilized diversion that can be a suitable alternative for a selected group of patients with competing co-morbidities and limited life expectancy. OBJECTIVE: To describe operative and perioperative characteristics as well as oncological outcomes for patients that underwent RARC + UCS. METHODS: Patients that underwent RARC + UCS during 2013-2023 in 3 centers (EU = 2, US = 1) were identified in a prospectively maintained database. Baseline characteristics, pathological, and oncological outcomes were analyzed. Descriptive statistics and survival analysis were performed using R language version 4.3.1. RESULTS: Sixty-nine patients were included. The median age was 77 years (IQR 70-80) and the median follow-up time was 11 months (IQR 4-20). Ten patients were ASA 4 (14.5%). Nine patients underwent palliative cystectomy (13%). The median operation time was 241 min (IQR 202-290), and the median hospital stay was 8 days (IQR 6-11). The 30-day complication rate was 55.1% (grade ≥ 3a was 14.4%), and the 30-day readmission rate was 17.4%. Eleven patients developed metastatic recurrence (15.9%), and 14 patients (20.2%) died during the follow-up period. Overall survival at 6, 12, and 24 months was 84%, 81%, and 73%, respectively. CONCLUSIONS: RARC + UCS may offer lower complication and readmission rates without the need to perform enteric anastomosis, it can be considered in a selected group of patients with competing co-morbidities, or limited life expectancy. Larger prospective studies are necessary to validate these results.

Peri- and post-operative outcomes of robot-assisted radical cystectomy after the implementation of the EAU guidelines recommendations for collecting and reporting complications at a high-volume referral center.

PURPOSE: No studies relied on a standardized methodology to collect postoperative complications after robot-assisted radical cystectomy (RARC). The aim of our study was to evaluate peri- and post-operative outcomes of patients undergoing RARC adhering to the European Association of Urology (EAU) recommendations for reporting surgical outcomes and using a long postoperative follow-up. MATERIALS AND METHODS: 246 patients who underwent RARC with intracorporal urinary diversion at a single tertiary referral center with a postoperative follow-up ≥ 1 year for survivors. Postoperative outcomes were collected prospectively by interviews done by medical doctors. Complications were scored using the Clavien-Dindo classification (CD), grouped by type and severity (severe: CD score ≥ 3). We described peri- and post-operative outcomes and complication chronological distribution. RESULTS: Overall, 16 (6.5%) and 225 patients (91%) experienced intraoperative and postoperative complications, respectively. Moreover, 139 (57%) experienced severe complications. The most common any-grade and severe complications were infectious (72%) and genitourinary (35%), respectively. Overall, 52% of complications (358/682) occurred within 10 days from surgery, and 51% of severe complications (106/207) occurred within 35 days. However, 13% of complications (90/682) and 28% of severe complications (59/207) occurred 3 months after surgery. The earliest complications were fever of unknown origins and paralytic ileus (median time-to-complication [mTTC]: 4 days), the latest complications were urinary tract infection (mTTC: 40 days) and hydronephrosis/ureteral obstruction (mTTC: 70 days). CONCLUSIONS: The rate of postoperative complications after RARC is > 90% when a standardized collection method and a long follow-up is implemented. These results should be used to identify potential areas of improvement and for preoperative patient counseling.

A phase 2 pilot study of water irrigation after transurethral resection of bladder tumor (WATIP) demonstrating safety, feasibility and activity.

PURPOSE: Non-muscle-invasive bladder cancer (NMIBC) can recur, partly due to seeding of free tumour cells after transurethral resection of bladder tumour (TURBT). Intravesical chemotherapy post-TURBT can reduce the risk but is used infrequently and inconsistently due to cost, complexity and side effects. The objective of this study was to prospectively assess continuous bladder irrigation using water, which may be a safer and easier alternative with comparable effectiveness. METHODS: WATIP was a prospective, single-arm phase 2 study of water irrigation during and for at least 3 h after TURBT for bladder tumours noted on imaging or flexible cystoscopy. Participants were assessed clinically for adverse effects and with blood tests within 24 h for sodium, haemoglobin and lactate dehydrogenase. The primary endpoints were safety (defined as < 10% adverse events of CTCAE grade ≥ 3), and feasibility (defined as the intervention being delivered as planned in > 90% of cases) and secondary endpoint was recurrence-free rates (RFR). RESULTS: Water irrigation was delivered as planned in 29 (97%) of 30 participants (median age 67 years, 25 (83%) males). The only adverse event (grade 2) was clot retention in one (3.3%) participant. Water irrigation significantly reduced urothelial cell counts in catheter effluent over time, unlike saline irrigation which did not. RFR was 56.2% (9/16 participants with low-risk NMIBC) at first cystoscopy (median interval 108 days) and 62.5% (5/8 evaluable low-risk NMIBC) at 12 months. CONCLUSION: Water irrigation during and after TURBT is feasible and safe. Prospective assessment of its effect on NMIBC recurrence compared to post-TURBT intravesical chemotherapy is needed before recommending its use in routine clinical practice.

Induction and maintenance of sequential intravesical gemcitabine/docetaxel for intermediate and high-risk non-muscle invasive bladder cancer with different dosage protocols.

INTRODUCTION: The combination of sequential intravesical gemcitabine and docetaxel (Gem/Doce) chemotherapy has been considered a feasible option for BCG (Bacillus Calmette-Guérin) treatment in non-muscle invasive bladder cancer (NMIBC), gaining popularity during BCG shortage period. We seek to determine the efficacy of the treatment by comparing Gem/Doce induction alone vs induction with maintenance, and to evaluate the treatment outcomes of two different dosage protocols. METHODS: A bi-center retrospective analysis of consecutive patients treated with Gem/Doce for NMIBC between 2018 and 2023 was performed. Baseline characteristics, risk group stratification (AUA 2020 guidelines), pathological, and surveillance reports were collected. Kaplan-Meier survival analysis was performed to detect Recurrence-free survival (RFS). RESULTS: Overall, 83 patients (68 males, 15 females) with a median age of 73 (IQR 66-79), and a median follow-up time of 18 months (IQR 9-25), were included. Forty-one had an intermediate-risk disease (49%) and 42 had a high-risk disease (51%). Thirty-seven patients (45%) had a recurrence; 19 (23%) had a high-grade recurrence. RFS of Gem/Doce induction-only vs induction + maintenance was at 6 months 88% vs 100%, at 12 months 71% vs 97%, at 18 months 57% vs 91%, and at 24 months 31% vs 87%, respectively (log-rank, p < 0.0001). Patients who received 2 g Gemcitabine with Docetaxel had better RFS for all-grade recurrences (log-rank, p = 0.017). However, no difference was found for high-grade recurrences. CONCLUSION: Gem/Doce induction with maintenance resulted in significantly better RFS than induction-only. Combining 2 g gemcitabine with docetaxel resulted in better RFS for all-grade but not for high-grade recurrences. Further prospective trials are necessary to validate our results.

Factors affecting the non-publication of clinical trials of prevalent urological cancer.

OBJECTIVES: Clinical trials (CTs) are critical in understanding and managing cancer. However, despite being completed, CT results are often unpublished, compromising the ability to glean useful information from them. This study aimed to evaluate factors influencing the non-publication of urological oncology clinical trials. METHODOLOGY: We conducted a comprehensive search of ClinicalTrials.gov to identify CTs focused on urological cancers completed between 2000 and 2020. We used the National Clinical Trial (NCT) identifier number to check whether the trial was published. RESULTS: 9,145 oncology CTs were conducted between 2000 and 2020, of which 8.39% (n = 767) focused on urological cancers, and 47.2% (n = 362) of these trials remained unpublished. Univariable analysis revealed that trials with a sample size of less than 50 and phase 4 were significantly associated with non-publication p < 0.001. In contrast, trials involving triple masking, a higher number of agents, and those conducted in High-Income Countries were associated with a higher likelihood of publication p < 0.05. Multivariable analysis demonstrated that trials enrolling more than 50 patients and employing three or more agents, along with triple and quadruple masking, had higher odds of being published (OR = 1.62; 95%CI (1.22-2.16), 1.89; 95%CI (1.10-3.27), 3.04; 95%CI (1.44-6.44), 5.62; 95%CI (1.72-18.37), and 5.41; 95%CI (1.76-16.67), p < 0.05, respectively). However, trials conducted in low-middle-income Countries had lower odds of publication (OR = 0.26; 95%CI (0.08-0.87), p = 0.02). CONCLUSION: We found that almost one-half (47.2%) of all completed urologic oncology clinical trials are not published in a PubMed-indexed journal. This non-publication rate represents a significant loss of scientific knowledge and progress. We identified several key variables including sample size.

Enfortumab vedotin following platinum-based chemotherapy and immune checkpoint inhibitors for advanced urothelial carcinoma: response, survival and safety analysis from a multicentre real-world Japanese cohort.

OBJECTIVE: Real-world evidence regarding enfortumab vedotin for unresectable or metastatic urothelial carcinoma is scarce, particularly in Japan. We investigated real-world data focusing on patient background, previous treatments, response, survival and adverse events in patients receiving enfortumab vedotin. METHODS: A multicentre database was used to register 556 patients diagnosed with metastatic urothelial carcinoma from 2008 to 2023; 34 patients (6.1%) treated with enfortumab vedotin were included. Best radiographic objective responses were evaluated using the Response Evaluation Criteria in Solid Tumors (v1.1) during treatments. Overall survival and progression-free survival were estimated (Kaplan-Meier method). Toxicities were reported according to the Common Terminology Criteria for Adverse Events, version 5.0. The relative dose intensity, which could impact oncological outcomes, was calculated. RESULTS: The median number of enfortumab vedotin therapy cycles was 5. The best objective response to enfortumab vedotin was partial response, stable disease and progressive disease in 19 (56%), 5 (15%) and 10 (29%) patients, respectively. The median overall survival and progression-free survival after the first enfortumab vedotin dose were 16 and 9 months, respectively. No significant relationship was observed between survival outcomes after enfortumab vedotin initiation and the enfortumab vedotin relative dose intensity. The median overall survival from first-line platinum-based chemotherapy initiation was 42 months. Twenty-six (76%) patients experienced any grade of enfortumab vedotin-related toxicities; eight (24%) experienced Grades 3-4 toxicities, the most common being skin toxicity (any grade, 47%; Grades 3-4, 12%). CONCLUSIONS: Here, we report real-world evidence for enfortumab vedotin therapy in Japan. Tumour responses and safety profiles were comparable with those of clinical trials on this novel treatment.

Comparisons of in-hospital fee and surgical outcomes between robot-assisted, laparoscopic, and open radical cystectomy: a Japanese nationwide study.

OBJECTIVE: To evaluate in-hospital fees and surgical outcomes of robot-assisted radical cystectomy (RARC), laparoscopic radical cystectomy (LRC) and open radical cystectomy (ORC) using a Japanese nationwide database. METHODS: All data were obtained from the Diagnosis Procedure Combination database between April 2020 and March 2022. Basic characteristics and perioperative indicators, including in-hospital fees, were compared among the RARC, LRC and ORC groups. Propensity score-matched comparisons were performed to assess the differences between RARC and ORC. RESULTS: During the study period, 2931, 1311 and 2435 cases of RARC, LRC and ORC were identified, respectively. The RARC group had the lowest in-hospital fee (median: 2.38 million yen), the shortest hospital stay (26 days) and the lowest blood transfusion rate (29.5%), as well as the lowest complication rate (20.9%), despite having the longest anesthesia time (569 min) among the three groups (all P < 0.01). The outcomes of LRC were comparable with those of RARC, and the differences in these indicators between the RARC and ORC groups were greater than those between the RARC and LRC groups. In propensity score-matched comparisons between the RARC and ORC groups, the differences in the indicators remained significant (all P < 0.01), with an ~50 000 yen difference in in-hospital fees. CONCLUSIONS: RARC and LRC were considered to be more cost-effective surgeries than ORC due to their superior surgical outcomes and comparable surgical fees in Japan. The widespread adoption of RARC and LRC is expected to bring economic benefits to Japanese society.

Caregiver experiences of caring for family members with urostomy: a qualitative study.

OBJECTIVE: In China, bladder tumors rank first for morbidity and mortality among urological and reproductive system tumors. Total radical cystectomy plus urinary flow conversion is the gold standard for the treatment of muscle-layer invasive bladder cancer. With an increasing number of radical cystectomies each year, the number of patients living with urostomy is growing. After discharge, primary care of urostomy patients is given at home, and high demands are placed on home caregivers due to issues of privacy and the complexity of replacing the urostomy device. This research explored the challenges faced by the family caregivers of urostomy patients. METHODS: We used descriptive qualitative research methods to conduct interviews with twenty-five family caregivers of patients with urostomy. Survey subjects were from five general hospitals. All interviews were recorded, transcribed, and analyzed using thematic analysis. RESULTS: Three critical challenges were identified-confusion, family crisis, and struggle psychology. Within these three themes, six sub-themes were constructed by coders. They were knowledge and skill deficiency, strong insecurities and uncertainties, role conflict, economic burden, emotional overwhelmed and calm acceptance. CONCLUSION: Family caregivers play a critical role in patient care, and especially in urostomy care. Caregiving is associated with significant challenges that hinder the family caregiver's ability to effectively care for the patient, further diminishing the caregiver's quality of life. Therefore, healthcare professionals should consider the challenges faced by family caregivers and take measures to obviate them through education, preparation, and support.

Comparative evaluation of reproductive organ-preserving versus standard radical cystectomy in female: a meta-analysis and systematic review of perioperative, oncological, and functional outcomes.

BACKGROUND: To evaluate the perioperative, oncological, and functional outcomes of reproductive organ-preserving radical cystectomy (ROPRC) compared to standard radical cystectomy (SRC) in the treatment of female bladder cancer. METHODS: A systematic search was conducted in November 2023 across several scientific databases. We executed a systematic review and cumulative meta-analysis of the primary outcomes of interest, adhering to the PRISMA and AMSTAR guidelines. The study was registered in PROSPERO (CRD42024501522). RESULTS: The meta-analysis included 10 studies with a total of 2015 participants. ROPRC showed a significant reduction in operative time and postoperative fasting period compared to SRC (MD - 45.69, 95% CI - 78.91 ~ - 12.47, p = 0.007, and MD - 0.69, 95% CI - 1.25 ~ - 0.13, p = 0.02, respectively). Functional outcomes, both daytime continence rate (OR 4.94, 95% CI 1.53 ~ 15.91, p = 0.008) and nighttime continence rate (OR 5.91, 95% CI 1.94 ~ 18.01, p = 0.002), and sexual function measured by the Female Sexual Function Index (MD 5.72, 95% CI 0.19 ~ 11.26, p = 0.04), were significantly improved in the ROPRC group. There were no significant differences between ROPRC and SRC in terms of estimated blood loss, length of hospital stay, overall postoperative complications, minor complications or major complications. Oncologically, both procedures showed comparable outcomes with no significant differences in positive surgical margins, tumor recurrence rates, overall survival, cancer-specific survival, recurrence-free survival, or progression-free survival. CONCLUSIONS: ROPRC is a viable and effective alternative to SRC in female bladder cancer patients, offering enhanced functional outcomes and similar oncological safety. These findings suggest that ROPRC can improve the quality of life in female bladder cancer patients without compromising the efficacy of cancer treatment.

Prevalence of diabetes and hospitalization due to poor glycemic control in people with bladder cancer or renal cell carcinoma in Sweden.

BACKGROUND: Bladder cancer (BC) and Renal cell carcinoma (RCC) are the most common urogenital cancers among both sexes, with a yearly global incidence of around 500 000 each. Both BC and RCC have been linked to diabetes. Poor glycemic control (malglycemia) is a serious consequence of diabetes and a possible consequence of systemic treatments used in BC and RCC. The objective of this study was to investigate the prevalence of diabetes and use of hospital-based care for malglycemia in people with BC or RCC. METHODS: This Swedish retrospective population-based register study used national health-data registers for longitudinal data on cancer incidence covering 15 years, use of hospital-based health care, and filled prescriptions of outpatient medications. Study endpoints included co-prevalence of diabetes in individuals with BC/RCC, healthcare resource utilization due to malglycemia, use of systemic corticosteroids, and changes in diabetes management for people with concomitant type 2 diabetes. RESULTS: We identified 36,620 and 15,581 individuals diagnosed with BC and RCC, respectively, between 2006 and 2019. The proportion of individuals registered with diabetes was 24% in BC and 23% in RCC. An association between BC/RCC and poor glycemic control was found, although the number of malglycemic events in hospital-based care were few (65/59 per 1000 individuals with diabetes and BC/RCC respectively with at least one event). An earlier switch to insulin-based diabetes management was observed in BC/RCC compared to matched individuals with type 2 diabetes but no cancer. The results also indicated an association between steroid treatment and poor glycemic control, and that systemic corticosteroids were more common among people with BC/RCC compared to diabetes controls. CONCLUSION: The high prevalence of diabetes and increased use of systemic corticosteroid treatment observed in this large national study highlights the need for specific clinical management, risk-assessment, and monitoring of individuals with BC/RCC and diabetes.

Difference of oncological efficacy between two immune checkpoint inhibitors following first-line platinum-based chemotherapy in patients with unresectable, metastatic, advanced urothelial carcinoma: a multicenter real-world Japanese cohort.

BACKGROUND: Maintenance avelumab is currently recommended for patients with unresectable and/or metastatic (mUC) achieving at least stable disease (SD) on first-line platinum-based chemotherapy (1L-CT). Pembrolizumab is an alternative therapeutic avenue for this patient cohort in clinical practice. We investigated real-world data, focusing on the correlation between response to 1L-CT and oncological efficacy of subsequent immune checkpoint inhibitor (ICI) therapy with avelumab or pembrolizumab. METHODS: A multicenter database registered 626 patients with mUC diagnosed from 2008-2023; among these, 175 receiving 2-6 cycles of 1L-CT followed by ICI therapy. Patients were categorized based on response to 1L-CT using the Response Evaluation Criteria in Solid Tumors (v1.1). Objective response rate on ICI, progression to ICI-free survival (ICI-PFS), and overall survival from start of 1L-CT were compared between avelumab-treated and pembrolizumab-treated patients in each response subgroup. RESULTS: ICI-PFS was significantly longer in patients achieving partial response on 1L-CT and subsequently receiving pembrolizumab compared to those receiving avelumab. Notably, patients achieving SD on 1L-CT and subsequently receiving pembrolizumab manifested significantly higher objective response rate (14% and 41%, respectively) and prolonged ICI-PFS relative to those receiving avelumab. In contrast, overall survival did not delineate difference between patients treated with avelumab versus pembrolizumab. Similar findings were discerned in the subanalysis of patients having favorable SD (tumor shrinkage, from - 29 to 0%) and unfavorable SD (tumor enlargement, from + 1 to + 19%) on 1L-CT. CONCLUSIONS: Our study provides real-world evidence regarding difference of oncological efficacy between maintenance avelumab and subsequent pembrolizumab in patients with mUC who achieved partial response or SD on 1L-CT.
