Large-scale validation study of an improved semiautonomous urine cytology assessment tool: AutoParis-X. Cancer Cytopathol 2023; 131:637-654.

Abstract
BACKGROUND Adopting a computational approach for the assessment of urine cytology specimens has the potential to improve the efficiency, accuracy, and reliability of bladder cancer screening, which has heretofore relied on semisubjective manual assessment methods. As rigorous, quantitative criteria and guidelines have been introduced for improving screening practices (e.g., The Paris System for Reporting Urinary Cytology), algorithms to emulate semiautonomous diagnostic decision-making have lagged behind, in part because of the complex and nuanced nature of urine cytology reporting. METHODS In this study, the authors report on the development and large-scale validation of a deep-learning tool, AutoParis-X, which can facilitate rapid, semiautonomous examination of urine cytology specimens. RESULTS The results of this large-scale, retrospective validation study indicate that AutoParis-X can accurately determine urothelial cell atypia and aggregate a wide variety of cell-related and cluster-related information across a slide to yield an atypia burden score, which correlates closely with overall specimen atypia and is predictive of Paris system diagnostic categories. Importantly, this approach accounts for challenges associated with the assessment of overlapping cell cluster borders, which improve the ability to predict specimen atypia and accurately estimate the nuclear-to-cytoplasm ratio for cells in these clusters. CONCLUSIONS The authors developed a publicly available, open-source, interactive web application that features a simple, easy-to-use display for examining urine cytology whole-slide images and determining the level of atypia in specific cells, flagging the most abnormal cells for pathologist review. The accuracy of AutoParis-X (and other semiautomated digital pathology systems) indicates that these technologies are approaching clinical readiness and necessitates full evaluation of these algorithms in head-to-head clinical trials.

Large-scale longitudinal comparison of urine cytological classification systems reveals potential early adoption of The Paris System criteria. J Am Soc Cytopathol 2022; 11:394-402.

Abstract
INTRODUCTION Urine cytology is used to screen for urothelial carcinoma in patients with hematuria or risk factors (eg, smoking, industrial dye exposure) and is an essential clinical triage and longitudinal monitoring tool for patients with known bladder cancer. However, urine cytology is semisubjective and thus susceptible to issues including specimen quality, interobserver variability, and "hedging" towards equivocal ("atypical") diagnoses. These factors limit the predictive value of urine cytology and increase reliance on invasive procedures (cystoscopy). The Paris System for Reporting Urine Cytology (TPS) was formulated to provide more quantitative/reproducible endpoints with well-defined criteria for urothelial atypia. TPS is often compared to other assessment techniques to justify its adoption. TPS results in decreased use of the atypical category and better reproducibility. Previous reports comparing diagnoses pre- and post-TPS have not considered temporal differences between diagnoses made under prior systems and TPS. By aggregating across time, studies may underestimate the magnitude of differences between assessment methods. MATERIALS AND METHODS We conducted a large-scale longitudinal reassessment of urine cytology using TPS criteria from specimens collected from 2008 to 2018, prior to the mid-2018 adoption of TPS at an academic medical center. RESULTS Findings indicate that differences in atypical assignment were largest at the start of the period and these differences progressively decreased towards insignificance just prior to TPS implementation. CONCLUSIONS This finding suggests that cytopathologists had begun to utilize the quantitative TPS criteria prior to official adoption, which may more broadly inform adoption strategies, communication, and understanding for evolving classification systems in cytology.

Abstract
CONTEXT Surveillance of the urethra and management of urethral recurrence (UR) after radical cystectomy (RC) is an area with poor evidence. OBJECTIVE We aimed to summarize the available evidence and provide clinicians with practical recommendations on how to prevent and manage UR after RC for bladder cancer. EVIDENCE ACQUISITION The MEDLINE and EMBASE databases were searched during September 2021 for studies evaluating UR after RC. The primary endpoint was oncologic outcomes for patients who experienced UR depending on different surveillance and management approaches. EVIDENCE SYNTHESIS Forty-three studies were included in the quantitative synthesis. According to the currently available literature, a tight-knitted surveillance protocol should be implemented for males treated with RC and nonorthotopic neobladder diversion as well as patients with prostatic involvement, tumor multifocality, bladder neck involvement, and concomitant carcinoma in situ. A survival benefit of a prophylactic urethrectomy has been reported only in patients at very high risk for UR based on clinical factors. Surveillance protocols were highly heterogeneous and poorly documented among included studies. Patients whose UR was diagnosed based on clinical symptoms had a poor prognosis. Only limited data were available on the comparative effectiveness of watchful waiting after RC versus clinical symptom screening as part of a follow-up strategy. However, the use of regular cytology and/or urethroscopy seems useful in select patients at high risk for UR. Despite limited data on the optimal management of UR, urethra-sparing approaches (transurethral resection of UR) seem to be an option for Ta (only) recurrences; a salvage urethrectomy with or without chemotherapy should be the standard for all others. CONCLUSIONS Based on the currently available literature, we have proposed an algorithm to guide the decision-making process to help identify and treat UR after RC. Given the lack of evidence on how to deal with UR and surveil patients at risk for UR, this study may invigorate research in this area of unmet need. PATIENT SUMMARY Early diagnosis and tailored management of urethral recurrence could help improve oncologic outcomes in these patients.

Abstract
Intravesical instillation therapy is increasingly recognized as one of the most common clinical treatment strategies for bladder cancer. However, the antitumor efficacy of chemotherapy drugs is still limited due to their rapid clearance by periodic urination. To circumvent this issue, a drug-loaded thin film comprising the self-assembly of tannic acid (TA) and ferric ions (Fe3+) was in situ fabricated on the bladder wall in vivo. As expected, the TA@Fe film with adjustable thickness could effectively prolong the residence time of anticancer drugs in the bladder and realize sustained release of anticancer drugs. Together with the antibacterial properties, the TA@Fe film enabled improved chemotherapeutic efficacy. Moreover, the TA@Fe film caused no adverse effects on bladder function, demonstrating the in vivo biocompatibility. In addition, the T2 contrast effect of Fe3+ was employed to real-time monitor the disassembly of the TA@Fe film and the ensuing drug release process by magnetic resonance imaging. We believe that the TA@Fe-based drug delivery platform with enhanced retention in the bladder would be of great potential for treating various bladder diseases.

Abstract
We aimed to conduct a systematic review and meta-analysis assessing the incidence and risk factors of urethral recurrence (UR) as well as summarizing data on survival outcomes in patients with UR after radical cystectomy (RC) for bladder cancer. The MEDLINE and EMBASE databases were searched in February 2021 for studies of patients with UR after RC. Incidence and risk factors of UR were the primary endpoints. The secondary endpoint was survival outcomes in patients who experienced UR. Twenty-one studies, comprising 9,435 patients, were included in the quantitative synthesis. Orthotopic neobladder (ONB) diversion was associated with a decreased probability of UR compared to non-ONB (pooled OR: 0.44, 95% CI: 0.31-0.61, P < 0.001) and male patients had a significantly higher risk of UR compared to female patients (pooled OR: 3.16, 95% CI: 1.83-5.47, P < 0.001). Among risk factors, prostatic urethral or prostatic stromal involvement (pooled HR: 5.44, 95% CI: 3.58-8.26, P < 0.001; pooled HR: 5.90, 95% CI: 1.82-19.17, P = 0.003, respectively) and tumor multifocality (pooled HR: 2.97, 95% CI: 2.05-4.29, P < 0.001) were associated with worse urethral recurrence-free survival. Neither tumor stage (P = 0.63) nor CIS (P = 0.72) were associated with worse urethral recurrence-free survival. Patients with UR had a 5-year CSS that varied from 47% to 63% and an OS - from 40% to 74%; UR did not appear to be related to worse survival outcomes. Male patients treated with non-ONB diversion as well as patients with prostatic involvement and tumor multifocality seem to be at the highest risk of UR after RC. Risk-adjusted standardized surveillance protocols should be developed into clinical practice after RC.

Abstract
Purpose Patients frequently undergo radical cystectomy and urinary diversion for treatment of bladder cancer. However, they remain at risk of urethral recurrence (UR). Studies have determined various risk factors leading to urethral recurrence. However, no publications have weighed the predictive values of these factors. Materials and Methods Studies published between 1971 and 2016 were retrieved from PubMed, EMBASE and MEDLINE. We used STATA software (Version 12.0) to estimate the pooled risk ratio. Results Twenty-five publications with 9498 patients were included. Overall, male patients, especially those with concomitant carcinoma in situ, superficial or intravesical bladder cancer, non-orthotopic diversion, prostatic involvement, bladder neck involvement, positive urethral margins or multifocal bladder cancer were at higher risk of urethral recurrence. The overall risks of recurrence, reported as risk ratios, varied widely. Among all 25 studies, 118 (60.2%) cases in 9 studies were diagnosed through routine follow-up. Another 82 (40.8%) patients in 11 studies first reported symptomatic abnormalities. Prognoses were worse for patients with symptomatic recurrence. Urethral cytology was the most common diagnostic method. Treatment after UR was reported for 272 cases in 14 publications, and 190 patients underwent urethrectomy and 52 underwent urethra-sparing treatments. Outcomes after UR were described in 12 studies reporting 180 cases, and 41 patients were alive through the end of follow-up and 65 patients died of bladder cancer. Conclusions UR following radical cystectomy for bladder cancer was closely related to risk factors. Precautions, strict follow-up protocols and rational therapies were critical to patients with high risks of urethral recurrences.

Abstract
Introduction: The incidence, treatment, and outcome of urethral recurrence (UR) after radical cystectomy (RC) for muscle-invasive bladder cancer with orthotopic neobladder in women have rarely been addressed in the literature. Patients and Methods: A total of 12 patients (median age at recurrence: 60 years) who experienced UR after RC with an orthotopic neobladder were selected for this study from a cohort of 456 women from participating institutions. The primary clinical and pathological characteristics at RC, including the manifestation of the UR and its treatment and outcome, were reviewed. Results: The primary bladder tumors in the 12 patients were urothelial carcinoma in 8 patients, squamous cell carcinoma and adenocarcinoma in 1 patient each, and mixed histology in 2 patients. Three patients (25%) had lymph node-positive disease at RC. The median time from RC to the detection of UR was 8 months (range 4-55). Eight recurrences manifested with clinical symptoms and 4 were detected during follow-up or during a diagnostic work-up for clinical symptoms caused by distant metastases. Treatment modalities were surgery, chemotherapy, radiotherapy, and bacillus Calmette-Guérin urethral instillations. Nine patients died of cancer. The median survival after the diagnosis of UR was 6 months. Conclusions: UR after RC with an orthotopic neobladder in females is rare. Solitary, noninvasive recurrences have a favorable prognosis when detected early. Invasive recurrences are often associated with local and distant metastases and have a poor prognosis.

Abstract
Transitional cell carcinoma can develop as a multifocal tumor in the urinary system, especially in the bladder. Here, we report a 69-year-old man who had undergone transurethral resection for bladder tumor and had urethral recurrence that presented as a perineal mass 2 years after treatment. However, he had obtained normal cystoscopy, ultrasonography and computed tomography results at follow-up examinations.

Abstract
OBJECTIVE To report a retrospective study evaluating the management of superficial urethral recurrence after ileal neobladder construction in patients with bladder cancer. PATIENTS AND METHODS In 77 consecutive patients with ileal neobladder after radical cystectomy for invasive bladder cancer, urethral recurrence was evaluated and transurethral resection (TUR) used as an initial treatment for superficial urethral recurrence. Urethrectomy with urinary re-diversion was performed when further recurrence developed. RESULTS Four patients (5%) presented with a superficial urethral recurrence and all four were treated by TUR as initial therapy. One patient has had no evidence of recurrence after initial TUR, although the other three patients were later treated with salvage urethrectomy due to repeated urethral recurrence. As a result, the stage of urethral recurrence advanced from pTa to pT1-pT2 in two of the three patients. For urinary re-diversion, one patient had a conversion from a Studer pouch to an ileal conduit, using the afferent limb, and the other two were converted from a Hautmann pouch to a continent reservoir using the Appe-Mainz procedure. There was no evidence of metastasis or local recurrence in any of the four patients. CONCLUSION Urethral preservation at initial therapy for superficial recurrence might be reasonable, and sequential urethrectomy after attempted urethral preservation might be strategically feasible. Urinary re-diversion from a neobladder to a catheterizable continent reservoir using the appendix would be a good choice and maintains the quality of life.

Abstract
PURPOSE OF REVIEW Radical cystectomy remains the gold-standard therapy for invasive bladder cancer. Management of the urethra before, during, and after cystectomy, however, is still not standardized. Herein, the rationale for different management algorithms is given. RECENT FINDINGS The literature remains inconsistent regarding the best diagnostic and therapeutic management of the urethra before and during cystectomy as well as afterwards. The risk of urethral recurrence may in fact be lower after orthotopic urinary diversion, but the evidence for this and other recommendations comes from retrospective series. Urethral recurrence, although uncommon, continues to have a poor prognosis, and the optimal follow-up regimen is unclear. The importance of lifelong follow-up is unquestioned. SUMMARY Risk factors for urethral involvement/recurrence can be determined before, during, and after radical cystectomy. The best way to diagnose and predict who will recur, however, is still unknown, as is the optimal follow-up regimen and treatment for the remnant urethra. The type of urinary diversion may in fact influence disease recurrence, as it also affects possible therapy for patients with recurrence.
