Urine Biopsy as Dynamic Biomarker to Enhance Clinical Staging of Bladder Cancer in Radical Cystectomy Candidates. JCO Precis Oncol 2024; 8:e2300362.

Abstract
PURPOSE There is significant interest in identifying complete responders to neoadjuvant chemotherapy (NAC) before radical cystectomy (RC) to potentially avoid removal of a pathologically benign bladder. However, clinical restaging after NAC is highly inaccurate. The objective of this study was to develop a next-generation sequencing-based molecular assay using urine to enhance clinical staging of patients with bladder cancer. METHODS Urine samples from 20 and 44 patients with bladder cancer undergoing RC were prospectively collected for retrospective analysis for molecular correlate analysis from two clinical trials, respectively. The first cohort was used to benchmark the assay, and the second was used to determine the performance characteristics of the test as it correlates to responder status as measured by pathologic examination. RESULTS First, to benchmark the assay, known mutations identified in the tissue (MT) of patients from the Accelerated Methotrexate, Vinblastine, Doxorubicin, Cisplatin trial (ClinicalTrials.gov identifier: NCT01611662, n = 16) and a cohort from University of California-San Francisco (n = 4) were cross referenced against mutation profiles from urine (MU). We then determined the correlation between MU persistence and residual disease in pre-RC urine samples from a second prospective clinical trial (The pT0 trial; ClinicalTrials.gov identifier: NCT02968732). Residual MU status correlated strongly with residual disease status (pT0 trial; n = 44; P = .0092) when MU from urine supernatant and urine pellet were assessed separately and analyzed in tandem. The sensitivity, specificity, PPV, and NPV were 91%, 50%, 86%, and 63% respectively, with an overall accuracy of 82% for this second cohort. CONCLUSION MU are representative of MT and thus can be used to enhance clinical staging of urothelial carcinoma. Urine biopsy may be used as a reliable tool that can be further developed to identify complete response to NAC in anticipation of safe RC avoidance.

Abstract
OBJECTIVE To investigate the diagnostic value of urine cyclic RNA-0071196 (circRNA-0071196) in the patients with bladder urothelial carcinoma (BUC). METHOD The expression of circRNA-0071196 was detected in the urine samples using qRT-PCR from 40 BUC patients and 30 non-UBC patients at our department from December 2018 to September 2021. The expression difference of circRNA-0071196 was compared between the two groups, and the relationship between the expression of circRNA-0071196 in the urine of UBC patients and the clinical pathological characteristics was analyzed. RESULTS (1) The expression of circRNA-0071196 in the urine of BUC group was significantly higher than that in the non-BUC group (P < 0.05). (2) The expression of circRNA-0071196 in the urine of BUC group was not related to age, sex, or lymph node metastasis (P > 0.05). (3) The expression of circRNA-0071196 in the urine of BUC group was related to tumor T stage, tumor grade and muscle invasion. (4) The urine circRNA-0071196 expression effectively distinguished BUC patients from non-BUC patients. CONCLUSION The elevated expression of urine circRNA-0071196 in BUC patients indicates that circRNA-0071196 has promising potential as a non-invasive urinary biomarker for detecting BUC.

Abstract
INTRODUCTION The standard treatment for muscle-invasive bladder cancer (MIBC) is cisplatin-based neoadjuvant chemotherapy (NAC) followed by radical cystectomy or upfront radical cystectomy for cisplatin-ineligible patients. In those who are ineligible for or refuse radical cystectomy, trimodal therapy with chemoradiation is offered. However, with the success of immune checkpoint inhibitors (ICI) and antibody-drug conjugates such as enfortumab vedotin in the metastatic setting, several trials are implementing these drugs in the neoadjuvant setting for cisplatin ineligible patients. Indeed, nivolumab is approved as adjuvant therapy for high-risk muscle-invasive urothelial carcinoma. AREAS COVERED Clinical trials using ICI, ICI/ICI, and ICI/chemotherapy combination therapies in the perioperative setting have been completed. These clinical trials have demonstrated that neoadjuvant ICI are safe and have encouraging pCR, making them promising treatment options. Neoadjuvant enfortumab vedotin alone and in combination with pembrolizumab is also being studied, and preliminarily to have promising activity. ICI is also being combined with radiation therapy (RT) and early data indicate that ICI combined with RT or chemo-RT may be safe with promising activity. EXPERT OPINION Biomarkers are urgently needed to identify appropriate treatment options for individual patients. The use of novel treatment approaches and biomarkers will help shape the future of precision therapy for MIBC and enable bladder preservation.

A Systematic Review of Oncological Outcomes Associated with Bladder-sparing Strategies in Patients Achieving Complete Clinical Response to Initial Systemic Treatment for Localized Muscle-invasive Bladder Cancer. Eur Urol Oncol 2023; 6:251-262. [PMID: 36906510 DOI: 10.1016/j.euo.2023.02.008] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/01/2022] [Revised: 12/14/2022] [Accepted: 02/08/2023] [Indexed: 03/13/2023]
Abstract
CONTEXT Bladder-sparing strategies (BSSs) have been proposed for the treatment of muscle-invasive bladder cancer (MIBC) patients achieving clinical complete response (cCR) to initial systemic treatment to avoid toxicity related to radical cystectomy. OBJECTIVE To systematically review the current literature evaluating oncological outcomes of BSSs in patients achieving cCR to initial systemic treatment for localized MIBC. EVIDENCE ACQUISITION A computerized bibliographic search of the Medline, Embase, and Cochrane databases was performed for all studies reporting oncological outcomes of MIBC patients undergoing either surveillance or radiation therapy after achieving cCR to initial systemic treatment. Using the Preferred Reporting Items for Systematic Reviews and Meta-analyses guidelines, we identified 23 noncomparative prospective or retrospective studies published between 1990 and 2021. The mean bladder and metastatic recurrence rates (range) as well as the mean bladder preservation rate (BPR; range) were calculated, and overall survival (OS) was extracted from included reports. EVIDENCE SYNTHESIS Overall, 16 and seven studies evaluated surveillance (n = 610) and radiation therapy (n = 175) in MIBC patients achieving cCR to initial systemic treatment, respectively. With regard to surveillance, the median follow-up ranged from 10 to 120 mo, with a mean bladder recurrence rate of 43% (0-71%), including 65% of non-muscle-invasive bladder cancer (NMIBC) and 35% of MIBC recurrences. The mean BPR was 73% (49-100%). The mean metastatic recurrence rate was 9% (0-27%), while 5-yr OS rates ranged from 64% to 89%. With regard to radiation therapy, the median follow-up ranged from 12 to 60 mo, with a mean bladder recurrence rate of 15% (0-29%), including 24% of NMIBC, 43% of MIBC, and 33% of unspecified recurrences. The mean BPR was 74% (71-100%). The mean metastatic recurrence rate was 17% (0-22%), while the 4-yr OS rate was 79%. CONCLUSIONS Our systematic review showed that only low-level evidence supports the effectiveness of BSSs in selected patients achieving cCR to initial systemic treatment for localized MIBC. These preliminary findings highlight the need for further prospective comparative research to demonstrate its efficacy. PATIENT SUMMARY We reviewed studies evaluating bladder-sparing strategies in patients achieving complete clinical response to initial systemic treatment for localized muscle-invasive bladder cancer. Based on low-level evidence, we observed that selected patients could benefit from surveillance or radiation therapy in this setting, but prospective comparative research is requested to confirm their efficacy.

Abstract
Recurrence and progression rates vary widely among different histological subtypes of bladder cancer (BC). Normal-appearing mucosa in non-muscle invasive bladder cancer and muscle-invasive bladder cancer in cystoscopy and histopathology is a factor in staging and treatment. Telocytes (TCs) are spindle-shaped cells that connect with other cell types allowing communication though cytoskeletal signaling. They are involved in tissue regeneration and pathogenesis of diseases and cancer. In this study, 12 normal-appearing tissues from urinary bladder with BC, both invasive and non-invasive were evaluated in patients who had either trans-urethral resection of bladder tumor or cystectomy. In each case, cystoscopy, intraoperative inspection, and histopathology all confirmed the absence of cancerous elements. Five patients with neurogenic bladder were used as a control group. Immunohistochemistry revealed that c-Kit + cells were intensively distributed in bladder layers from BC samples, while they were seldom detected in the control group. Ultrastructural examination of reprocessed tissue showed an intense distribution of TCs and telopodes in the submucosa and between smooth muscle cells in BC. Telopodes were numerous, arborizing, and intercommunicating. Whereas TCs and telopodes were scarce in the neurogenic bladder. Also, cancerous tissue had the highest expression level of ezrin protein, and this level gradually decreased as we moved away from the tumor. Our finding of TCs number in normal-appearing tissues in conjunction with ezrin expression may compete invasiveness and possibly a trail to reduce recurrence rates.

Abstract
In the surgical oncology field, the change from a past radical surgery to an organ preserving surgery is a big trend. In muscle-invasive bladder cancer treatment, neoadjuvant chemotherapy (NAC) followed by radical cystectomy (RC) is the standard of care for muscle-invasive bladder cancer (MIBC) patients eligible for cisplatin. There is a growing interest in bladder preserving strategies after NAC because good oncologic outcome has been reported for pathologic complete response (pCR) patients after NAC, and many studies have continued to discuss whether bladder preservation treatment is possible for these patients. However, in actual clinical practice, decision-making should be determined according to clinical staging and there is a gap that cannot be ignored between clinical complete response (cCR) and pCR. Currently, there is a lack in a uniform approach to post-NAC restaging of MIBC and a standardized cCR definition. In this review, we clarify the gap between cCR and pCR at the current situation and focus on emerging strategies in bladder preservation in selected patients with MIBC who achieve cCR following NAC.

Abstract
BACKGROUND: One of the best predictors of positive outcomes in bladder cancer (BC) is pT0 following radical cystectomy (RC). Discordance between clinical and pathologic staging affects decision-making in patients with clinical absence of disease (cT0). OBJECTIVES: We sought to determine whether a restaging transurethral resection of bladder tumor (re-TURBT) improves clinical staging accuracy relative to pathologic stage RC in patients treated with neoadjuvant chemotherapy (NAC) versus those who did not receive NAC. METHODS: We queried our prospectively maintained IRB approved institutional database to identify 129 patients who underwent RC from 2013 to 2019 with a re-TURBT prior to RC. 53 patients were treated with NAC between their initial and re-TURBT and 76 patients were not treated with NAC. RESULTS: The overall upstaging rate from re-TURBT to RC was 34.9% . There was no significant difference in the upstaging rate between the NAC and no-NAC groups - 31.0% vs. 37.0%, respectively. In patients who were cT0 on re-TURBT, the NAC group did not show a significantly greater rate of pathologic clinical CR (pT0) than the no NAC group - 38.5% vs. 37.5%, respectively. Re-TURBT with staging < rT2 as a predictor for absence of MIBC on pathologic staging (<ypT2) did not show a significant difference between the NAC and no NAC group, with a negative predictive value (NPV) of 69.0% and 66.7%, respectively. CONCLUSIONS: Re-TURBT after NAC does not show statistically significant improvement in staging accuracy relative to pathologic stage at RC compared to re-TURBT in patients not treated with NAC.

Abstract
We describe the case of a 71-yr-old woman with locally advanced muscle-invasive bladder cancer and stage III chronic kidney disease due to an obstructed nonfunctional left kidney. She was started on neoadjuvant immunotherapy, but had to stop treatment because of acute worsening of renal function. Radical cystectomy was then performed uneventfully, revealing pT3aN1 urothelial carcinoma of the bladder. Adjuvant chemotherapy in high-risk locally advanced bladder cancer after radical cystectomy currently poses several challenges, especially for cisplatin-ineligible candidates. Recent data on adjuvant immunotherapy trials suggest a disease-free survival advantage for this subgroup of patients. The current and future role of immuno-oncology agents in this setting is discussed. PATIENT SUMMARY: Patients with advanced bladder cancer might benefit from further chemotherapy or immunotherapy following bladder removal, but it is still unclear which patients benefit the most from this strategy. Measurement of biomarkers and scans to show urinary function will probably help in optimising patient selection for this treatment in the near future.

Abstract
PURPOSE OF REVIEW Since the establishment of neoadjuvant chemotherapy as the standard of care for patients with muscle invasive bladder cancer, the pathologic absence of disease, denoted pT0, was found to be predictive of improved overall survival. Accordingly, it has been used in clinical trials as an optimal surrogate outcome measure, even in contemporary nonchemotherapeutic interventions. We review the role of pT0 as a catalyst for change in trial design and its suitability to facilitate more efficient and timely results. In addition, we explore the present and future of cT0, the clinical absence of disease, in defining treatment response and enabling bladder-sparing management options. RECENT FINDINGS The use of pT0 as a surrogate has provided initial results for the efficacy of immunotherapy in the neoadjuvant space. In combination with molecular markers, pT0 has improved our ability to identify treatment responders and its clinical counterpart, cT0, has been integrated into multiple trials to redefine postneoadjuvant chemotherapy management algorithms. SUMMARY The use of pT0 as a surrogate endpoint in bladder cancer trials has improved clinical trial design, defined efficacy of emerging therapeutics, and has the potential to redefine the postneoadjuvant treatment management for patients seeking bladder-sparing options.

Urinary Exosomal Long Noncoding RNA TERC as a Noninvasive Diagnostic and Prognostic Biomarker for Bladder Urothelial Carcinoma. J Immunol Res 2022; 2022:9038808.

Abstract
Purpose Bladder cancer is one of the most common urological malignancies worldwide, and approximately 90% of bladder cancer cases are histologically typed as bladder urothelial carcinoma (BLCA). Exosomes are 30 to 200 nm extracellular vesicles that transport microRNAs, long noncoding RNAs (lncRNAs), mRNAs, circular RNAs, and proteins across tissues and through circulation. Urinary exosomes may contain genetic information from tumor cells. Herein, we explored the clinical significance of urinary exosomal lncRNA telomerase RNA component (TERC) levels to provide an urgently needed diagnostic and prognostic biomarker for BLCA. Materials and Methods In this study, we used RNA-sequencing of samples from four BLCA patients and three healthy controls to identify that TERC was differentially expressed in urinary exosomes. We then used quantitative PCR in different types of clinical samples to validate the biomarker and analyzed results using receiver operating characteristic curves. Results We found that TERC was significantly upregulated in urinary exosomes from BLCA patients compared with those from healthy controls (P < 0.0001). Urinary exosomal TERC showed higher sensitivity (78.65%) and accuracy (77.78%) than existing indicators including nuclear matrix protein-22 and urine cytometry. Using the cut-off value 4.302, the area under the curve for urinary exosomal TERC was 0.836 (95% confidence interval: 0.768–0.891, P < 0.0001). Furthermore, this noninvasive assay could distinguish low-grade and high-grade tumors (P = 0.0153). Conclusions TERC is enriched in urinary exosomes from BLCA patients. Urinary exosomal TERC could become a diagnostic and prognostic biomarker for BLCA that allows clinicians to realize noninvasive detection of BLCA.
