RESUMO
OBJECTIVE: To analyse the impact of histological discordance of subtypes (subtypes or divergent differentiation [DD]) in specimens from transurethral resection (TUR) and radical cystectomy (RC) on the outcome of the patients with bladder cancer receiving RC. PATIENTS AND METHODS: We analysed data for 2570 patients from a Japanese nationwide cohort with bladder cancer treated with RC between January 2013 and December 2019 at 36 institutions. The non-urinary tract recurrence-free survival (NUTR-FS) and overall survival (OS) stratified by TUR or RC specimen histology were determined. We also elucidated the predictive factors for OS in patients with subtype/DD bladder cancer. RESULTS: At median follow-up of 36.9 months, 835 (32.4%) patients had NUTR, and 691 (26.9%) died. No statistically significant disparities in OS or NUTR-FS were observed when TUR specimens were classified as pure-urothelial carcinoma (UC), subtypes, DD, or non-UC. Among 2449 patients diagnosed with pure-UC or subtype/DD in their TUR specimens, there was discordance between the pathological diagnosis in TUR and RC specimens. Histological subtypes in RC specimens had a significant prognostic impact. When we focused on 345 patients with subtype/DD in TUR specimens, a multivariate Cox regression analysis identified pre-RC neutrophil-lymphocyte ratio and pathological stage as independent prognostic factors for OS (P = 0.016 and P = 0.001, respectively). The presence of sarcomatoid subtype in TUR specimens and lymphovascular invasion in RC specimens had a marginal effect (P = 0.069 and P = 0.056, respectively). CONCLUSION: This study demonstrated that the presence of subtype/DD in RC specimens but not in TUR specimens indicated a poor prognosis. In patients with subtype/DD in TUR specimens, pre-RC neutrophil-lymphocyte ratio and pathological stage were independent prognostic factors for OS.

PURPOSE: The International Bladder Cancer Group designated the subgroup that is resistant to Bacillus Calmette-Guérin (BCG) but does not meet the criteria for BCG-unresponsive NMIBC as "BCG-exposed high-risk NMIBC" to guide optimal trial design. We aimed to investigate the treatment patterns and prognoses of patients with BCG-exposed NMIBC. METHODS: We conducted a retrospective chart review of 3283 patients who received intravesical BCG therapy for NMIBC at 14 participating institutions between January 2000 and December 2019. Patients meeting the criteria for BCG-exposed and BCG-unresponsive NMIBC, as defined by the Food and Drug Administration and International Bladder Cancer Group, were selected. To compare treatment patterns and outcomes, high-risk recurrence occurring more than 24 months after the last dose of BCG was defined as "BCG-treated NMIBC." In addition, we compared prognoses between BCG rechallenge and early cystectomy in patients with BCG-exposed NMIBC. RESULTS: Of 3283 patients, 108 (3.3%), 150 (4.6%), and 391 (11.9%) were classified as having BCG-exposed, unresponsive, and treated NMIBC, respectively. BCG-exposed NMIBC demonstrated intermediate survival curves for intravesical recurrence-free and progression-free survival, falling between those of BCG-unresponsive and treated NMIBC. Among patients with BCG-exposed NMIBC, 48 (44.4%) received BCG rechallenge, which was the most commonly performed treatment, and 19 (17.6%) underwent early cystectomy. No significant differences were observed between BCG rechallenge and early cystectomy in patients with BCG-exposed NMIBC. CONCLUSIONS: The newly proposed definition of BCG-exposed NMIBC may serve as a valuable disease subgroup for distinguishing significant gray areas, except in cases of BCG-unresponsive NMIBC.

OBJECTIVE: To investigate the prevalence of frailty and its effects on cancer-related fatigue and quality of life among patients with prostate cancer. METHODS: In this cross-sectional study, questionnaires were administered to 254 outpatients who visited the Department of Urology at Kagawa University Hospital for prostate cancer; finally, 108 outpatients were analyzed. Frailty, cancer-related fatigue and quality of life were assessed using the G8 screening tool, Japanese version of the Brief Fatigue Inventory and Japanese version of the Short Form 8 Health Survey, respectively. We defined frailty based on a score ≤14 points and divided the patients into frailty and no-frailty groups. We also compared the severity of cancer-related fatigue and quality of life between groups. RESULTS: The prevalence of frailty among 108 outpatients was 63%. Older age correlated with frailty severity (P = 0.0007) but not cancer-related fatigue severity (P = 0.2391). The proportion of patients on treatment or with metastasis was not significantly different between groups. The frailty group had higher cancer-related fatigue severity (P = 0.004) and decreased levels of general activity, mood, walking ability, normal work and enjoyment of life, especially on the Brief Fatigue Inventory subscale. The frailty group had lower physical and mental quality of life than the no-frailty group or general population. CONCLUSIONS: The frailty rate for these patients increased with age, exceeding 60% regardless of the treatment status, and was associated with worsened cancer-related fatigue severity and reduced quality of life. Our study highlights the importance of assessing frailty when selecting treatment, especially in older patients.

OBJECTIVE: Several guidelines recommended that second transurethral resection should be performed in patients with diagnosis of high-risk non-muscle-invasive bladder cancer. However, therapeutic benefits of second transurethral resection before bacillus Calmette-Guérin intravesical instillation were conflicting amongst previous studies. We investigated the prognostic impact of second transurethral resection before bacillus Calmette-Guérin instillation in high-risk non-muscle-invasive bladder cancer patients. METHODS: This retrospective study included 3104 non-muscle-invasive bladder cancer patients who received bacillus Calmette-Guérin instillations between 2000 and 2019 at 31 collaborative institutions. Univariate and multivariate Cox proportional hazards models were used to assess the risk factors of intravesical recurrence, disease progression, cancer-specific mortality and overall mortality. RESULTS: In the entire population, patients undergoing second transurethral resection (33%, 1026/3104) had a lower risk of intravesical recurrence on univariate analysis (hazard ratio 0.85, 95% confidence interval 0.73-0.98, P = 0.027), although it did not remain significant on multivariate analysis (hazard ratio 0.90, 95% confidence interval 0.76-1.07, P = 0.24). Subgroup analysis revealed that, in pT1 patients (n = 1487), second transurethral resection was significantly correlated with a lower risk of intravesical recurrence on multivariate analysis (hazard ratio 0.80, 95% confidence interval 0.64-1.00, P = 0.048), but lower risks of disease progression (hazard ratio 0.75, 95% confidence interval 0.56-1.00, P = 0.049), cancer-specific mortality (hazard ratio 0.54, 95% confidence interval 0.35-0.85, P = 0.007) and overall mortality (hazard ratio 0.73, 95% confidence interval 0.55-0.97, P = 0.027) on univariate analysis. CONCLUSIONS: Second transurethral resection confers accurate pathological staging and could be used to safely select good candidates for intravesical bacillus Calmette-Guérin instillation. We further confirm that second transurethral resection could confer an oncological benefit in pT1 bladder cancer patients treated by bacillus Calmette-Guérin instillation, and so strongly recommend second transurethral resection in this patient population.

BACKGROUND: In the THOR trial (NCT03390504) Cohort 1, erdafitinib demonstrated significantly prolonged overall survival (OS) (median 12.1 versus 7.8 months) and reduced risk of death by 36% (hazard ratio 0.64, P = 0.005) compared with chemotherapy in metastatic urothelial carcinoma (mUC) patients with FGFR alterations who progressed after ≥ 1 prior treatments, including anti-PD-(L)1. There have been no reports of the Japanese subgroup results yet. METHODS: THOR Cohort 1 randomized patients to erdafitinib once daily or docetaxel/vinflunine once every 3 weeks. Primary endpoint was OS. Secondary endpoints included progression-free survival (PFS) and objective response rate (ORR). No specific statistical power was set for this Japanese subgroup analysis. RESULTS: Of 266 patients randomized, 27 (14 erdafitinib; 13 chemotherapy) were Japanese. Baseline characteristics were generally similar between treatments and to the overall population, except for more males, lower body weight, and more upper tract primary tumors among Japanese patients. Compared with chemotherapy, erdafitinib showed improved OS (median 25.4 versus 12.4 months), PFS (median 8.4 versus 2.9 months) and ORR (57.1% versus 15.4%). Any grade treatment-related adverse events (AEs) occurred in all patients from both arms but Grade 3/4 AEs and AEs leading to discontinuation were lower in the erdafitinib arm. No new safety signals were observed in the Japanese subgroup. CONCLUSION: In the Japanese subgroup, erdafitinib showed improved survival and response compared to chemotherapy, with no new safety concerns. These results support erdafitinib as a treatment option for Japanese mUC patients with FGFR alterations, and early FGFR testing after diagnosis of mUC should be considered.
RESUMO
BACKGROUND: To investigate the impact of different urinary diversion (UD) techniques on the peri- and postoperative complications of robot-assisted radical cystectomy (RARC) with ileal conduit. METHODS: We retrospectively analyzed 373 patients undergoing RARC with ileal conduit at 11 institutions in Japan between April 2018 and December 2021. Propensity score weighting was performed to adjust for confounding factors such as age, sex, body mass index, performance status, American Society of Anesthesiologists score, previous abdominal surgery, neoadjuvant chemotherapy, and preoperative high T stage (≥ cT3) and high N stage (≥ cN1). Perioperative complications were then compared among three groups: extracorporeal, intracorporeal, and hybrid urinary diversion (ECUD, ICUD, and HUD, respectively). RESULTS: A total of 150, 68, and 155 patients received ECUD, HUD, and ICUD, respectively. Bowel reconstruction time and UD time were significantly shorter in the ECUD group (p < 0.001), and console time was significantly longer and blood loss was significantly higher in the ICUD group (p < 0.001). For postoperative complications (Clavien-Dindo Classification grade ≥ 3), surgical site infection (p = 0.004), pelvic abscess (p = 0.013), anastomotic urine leak (p = 0.007), and pelvic organ prolapse (p = 0.011) significantly occurred in the ECUD group. For all grades, ileus was more common in the HUD group, whereas anastomotic stricture was more common in the ECUD group compared with the other groups (p < 0.05). CONCLUSIONS: Severe complications did not increase after HUD and ICUD compared with ECUD; however, console time tended to be longer and blood loss was slightly higher during RARC.

BACKGROUND: Enfortumab vedotin is a novel antibody-drug conjugate used as a third-line therapy for the treatment of urothelial cancer. We aimed to elucidate the effect of enfortumab vedotin-related peripheral neuropathy on its efficacy and whether enfortumab vedotin-induced early electrophysiological changes could be associated with peripheral neuropathy onset. METHODS: Our prospective multicenter cohort study enrolled 34 patients with prior platinum-containing chemotherapy and programmed cell death protein 1/ligand 1 inhibitor-resistant advanced urothelial carcinoma and received enfortumab vedotin. The best overall response, progression-free survival, overall survival, and safety were assessed. Nerve conduction studies were also performed in 11 patients. RESULTS: The confirmed overall response rate and disease control rate were 52.9% and 73.5%, respectively. The median overall progression-free survival and overall survival were 6.9 and 13.5 months, respectively, during a median follow-up of 8.6 months. The patients with disease control had significantly longer treatment continuation and overall survival than did those with uncontrolled disease. Peripheral neuropathy occurred in 12.5% of the patients. The overall response and disease control rates were 83.3% and 100%, respectively: higher than those in patients without peripheral neuropathy (p = 0.028 and p = 0.029, respectively). Nerve conduction studies indicated that enfortumab vedotin reduced nerve conduction velocity more markedly in sensory nerves than in motor nerves and the lower limbs than in the upper limbs, with the sural nerve being the most affected in the patients who developed peripheral neuropathy (p = 0.011). CONCLUSION: Our results indicated the importance of focusing on enfortumab vedotin-induced neuropathy of the sural nerve to maximize efficacy and improve safety.

To preserve the bladder without compromising survival, further treatments need to be optimized to prevent the recurrence and progression of non-muscle invasive bladder cancer. In clinical practice, transurethral resection of bladder tumors is essential for bladder cancer management. The primary goal of surgery is to achieve accurate pathological evaluation and complete resection of bladder cancer; high resection quality is required for the procedure. A representative surrogate indicator of the resection quality is the presence of the detrusor muscle in the resection specimen. Therefore, complete visual resection of bladder cancer with a muscle layer is crucial for decreasing the recurrence and progression rates of non-muscle-invasive bladder cancer. However, this procedure is complex and requires sufficient experience and knowledge to be performed thoroughly, safely, and efficiently. Surgical checklists represent an approach to filling the knowledge and experience gaps and improving the quality and safety of surgery. By checking items during transurethral resection, it is expected that the recording of risk factors related to recurrence and progression will improve, the rate of visually complete resection with muscles will increase, and the rate of intravesical recurrence will decrease. The simplicity of checklists is an additional benefit. In recent years, surgical checklists have received increasing attention in order to achieve high-quality resections and reduce disparities between surgeons and institutions. This literature review outlines the evolving treatment strategies for patients with non-muscle-invasive bladder cancer, focusing on surgical checklists for the transurethral resection of bladder tumors.

OBJECTIVES: To assess whether the coronavirus disease (COVID-19) pandemic affected the outcomes of robot-assisted radical prostatectomy (RARP) and urologists' treatment behaviors. METHODS: We retrospectively examined the medical records of 208 patients who had undergone RARP between August 2017 and December 2022. We compared the rate of preoperative androgen deprivation therapy (ADT), waiting period for RARP, patients' baseline characteristics and quality of life (QOL), proportion of adverse pathology on the RARP specimen, rate of Gleason grade group upgrading from biopsy to the RARP specimen, and prostate-specific antigen (PSA) recurrence-free survival between the pre-pandemic and pandemic groups. RESULTS: The rate of preoperative ADT was significantly higher during than before the COVID-19 pandemic (13.7% vs. 1.9%; p = 0.002). The baseline physical and mental QOL scores did not differ significantly between the groups. The proportion of D'Amico low-risk patients was significantly lower (13.6% vs. 1.2%, p = 0.005) and waiting period for RARP was significantly shorter (median 3.5 months vs. 4.0 months, p = 0.016) in the pandemic group than in the pre-pandemic group. There was no significant difference in the proportion of adverse pathology between the groups (p = 0.104); however, the upgrading rate was significantly higher in the pre-pandemic group (p = 0.002). There was no significant difference in PSA recurrence-free survival between the groups (log-rank, p = 0.752). CONCLUSIONS: The COVID-19 pandemic did not adversely affect the oncologic outcomes of RARP and QOL before RARP. However, it caused urologists to increase the use of preoperative ADT and to reserve RARP for higher-risk cases.

OBJECTIVES: To determine the effects of prophylactic urethrectomy (PU) on oncological and perioperative outcomes in patients with bladder cancer (BC) undergoing radical cystectomy (RC). METHODS: This retrospective study analyzed data on 1976 evaluable patients with BC who underwent RC. Patients were drawn from 36 institutions within the Japanese Urological Oncology Group. Oncological outcomes were compared using restricted mean survival times (RMSTs) based on inverse probability of treatment weighting (IPTW)-adjusted Kaplan-Meier curves for non-urinary tract recurrence-free survival (NUTRFS), cancer-specific survival (CSS), and overall survival (OS). Interaction terms within IPTW-adjusted Cox regression models were examined to assess the heterogeneity of treatment effect based on the risk of urethral recurrence (UR). The association between PU, estimated blood loss (EBL), and the incidence of severe postoperative surgical complications (SPSCs) (Clavien-Dindo grade 3 or higher) was analyzed. RESULTS: Of 1976 patients, 1448 (73.3%) received PU. IPTW adjustment was used to balance baseline characteristics between the treatment groups. Within the 107-month window of patient monitoring, PU showed no survival benefits (NUTRFS difference: 0.2 months [95% confidence interval: -6.8 to 7.3]; CSS, 1.2 [-4.9 to 7.3]; OS, 0 [-6.5 to 6.5]). No significant interactions were observed with factors associated with UR, and PU was associated with unfavorable perioperative outcomes (EBL, 1179 mL vs. 983 mL; SPSC, 14.6% vs. 7.0%). CONCLUSIONS: This study showed that (1) PU was not associated with survival in patients with BC undergoing RC, regardless of UR-associated factors, and (2) PU was associated with unfavorable perioperative outcomes.
RESUMO
OBJECTIVE: this study aimed to evaluate the active surveillance continuation period, treatment intervention rate and health-related quality of life in younger patients. METHODS: we prospectively conducted a health-related quality of life survey of patients enrolled in the Prostate Cancer Research International: Active Surveillance-JAPAN study at Kagawa University between January 2010 and December 2020. Health-related quality of life was assessed by mail using a validated Japanese version of the Short-Form 8 Health Survey and Expanded Prostate Cancer Index at active surveillance enrolment and annually thereafter until discontinuation of active surveillance. We divided the patients into two groups, younger (aged <65 years) and older (aged ≥65 years), and compared the two groups. RESULTS: of the 84 patients, 22 were in the younger group. The active surveillance continuation period was shorter in the younger group than in the older group. The 3-year treatment intervention rate was higher in the younger group than in the older group. The majority of the reasons for definitive treatment were related to the protocol, which was similar in both groups (80 versus 76%). The sexual summary scores at active surveillance enrolment were higher in the younger group than in the older group. During active surveillance, the younger group and the older group showed no deterioration in all health-related quality of life scores compared with the scores at the enrolment of active surveillance. CONCLUSIONS: patient-reported health-related quality of life survey indicated that the health-related quality of life of younger Japanese patients was maintained over time during active surveillance, similar to that of older patients.

OBJECTIVE: To conduct a national questionnaire survey of Japanese urologists on active surveillance (AS) for low- and intermediate-risk prostate cancer (PCa). METHODS: A questionnaire was sent to 922 Japanese Urological Association Teaching Base Hospitals. The items included were years of experience as a urologist, sex, workplace, treatment equipment owned, specialty area of daily practice, specialty area of urological cancer, and six hypothetical cases of AS. The cases were categorized by the following Gleason scores: 3 + 3 low risk of PCa, 3 + 4 intermediate risk, and 4 + 3 intermediate risk, with or without comorbidities for each case. Comorbidities were defined as cardiovascular diseases or illnesses warranting anticoagulant therapy. RESULTS: Altogether, 1962 questionnaires were analyzed. Responses were almost equally distributed among all age groups. Workplaces included general hospitals (49.4%), university hospitals (40.3%), and cancer centers (4.2%). Percentages of proposed AS for low risk/no comorbidity, low risk/with comorbidity, intermediate-risk 3 + 4/no comorbidity, intermediate risk 3 + 4/with comorbidity, intermediate risk 4 + 3/no comorbidity, and intermediate risk 4 + 3/with comorbidity were 90.5%, 90%, 39.5%, 48.7%, 15%, and 22%, respectively. Analysis of the correspondents' backgrounds showed that the more the urologists' years of experience, the less they were to advise AS of low-risk patients. In the presence of comorbidities, urologists across all age groups tended to propose AS, even in the same Gleason grade group. Cancer center urologists recommended AS more often than their counterparts at general and university hospitals. CONCLUSIONS: Approximately 40% of urologists proposed AS for intermediate-risk cases, confirming that AS for intermediate-risk patients is being considered in Japan.

OBJECTIVE: This study conducted a national questionnaire survey of Japanese urologists from a treatment perspective for older patients with prostate cancer. METHODS: A questionnaire was distributed to 922 teaching hospitals of the Japanese Urological Association. Questionnaire items included years of urologist experience, gender, workplace, treatment equipment owned, daily specialty practice area, urological cancer specialty, treatment reference items for older adults, upper age limit for radical treatment, medication, and two hypothetical cases of Gleason grade group 2 prostate cancer with or without oligometastasis. RESULTS: In total, 1732 questionnaires were analyzed, with responses evenly distributed across all age groups. Workplaces included general hospitals (49.4%), university hospitals (40.3%), and cancer centers (4.2%). Performance status was the most frequently mentioned treatment-related item, followed by comorbidities and cognitive function. In addition, geriatric assessment was used by only 13.3% of respondents. No upper age limit was found for total prostatectomy, brachytherapy, and external beam radiation. Anti-androgens, androgen receptor-axis-targeted agents, chemotherapy, poly ADP ribose polymerase inhibitors, and immune-checkpoint inhibitors were selected by 6.8%, 35.6%, 47.3%, 89%, 62.8%, 24.7%, 41.9%, and 41.7% of the respondents, respectively. Response rates for administration of hormone therapy for hypothetical cases of Gleason grade group 2 prostate cancer with or without oligometastases were 96.8% and 61.2%, respectively. CONCLUSIONS: Less than 15% of urologists used geriatric assessments. Several responded that they would set age limits for highly invasive radical and systemic therapies.

OBJECTIVE: To investigate the involvement of pretreatment C-reactive protein (CRP) and neutrophil-to-lymphocyte ratio (NLR) in the prognosis of patients who underwent intravesical bacillus Calmette-Guérin (BCG) therapy for non-muscle invasive bladder cancer (NMIBC). METHODS: The clinicopathological data of 1709 patients with NMIBC who underwent initial intravesical BCG therapy after transurethral resection of bladder tumor were retrospectively analyzed to evaluate the outcome of intravesical BCG therapy in a multicenter study conducted by the Japan Urological Oncology Group. The prognoses of these patients were analyzed to determine whether the biomarkers (CRP and NLR) could predict the efficacy of intravesical BCG therapy. Patients were divided into two groups according to the pretreatment CRP and NLR, with cutoff values defined as CRP ≥ 0.5 mg/dl and NLR ≥ 2.5, based on several previous reports. RESULTS: In the univariable analysis, CRP ≥ 0.5 mg/dl was significantly associated with intravesical recurrence, cancer-specific survival, and bladder cancer (BC) progression, while NLR ≥ 2.5 was not significantly associated with patient prognosis. In the multivariable analysis, CRP ≥ 0.5 mg/dl was significantly associated with intravesical recurrence and BC progression. The concordance index was used to examine the accuracy in predicting recurrence and progression events. While CRP was slightly, though not statistically significant, inferior to the European Association of Urology risk classification, the combination of them showed improved predictive accuracy. CONCLUSION: This study suggests that CRP can be a prognostic factor after intravesical BCG therapy and may provide useful data for determining treatment and follow-up strategies for patients with NMIBC.

OBJECTIVES: To assess the impact of histological variants on survival and response to treatment with pembrolizumab in patients with chemo-resistant urothelial carcinoma (UC). PATIENTS AND METHODS: The medical records of 755 patients with advanced UC who received pembrolizumab were reviewed retrospectively. Patients were classified into pure UC (PUC) and each variant. Best overall response (BOR) and overall survival (OS) were compared between the groups using a propensity score matching (PSM). RESULTS: Overall, 147 (19.5%) patients harboured any histological variant UC (VUC). After PSM, there were no significant differences in the objective response rate (ORR, 24.5% vs 17.3%, P = 0.098) or disease control rate (DCR, 36.7% vs 30.2%, P = 0.195) when comparing patients with any VUC and PUC. Furthermore, any VUC, as compared with PUC, was associated with a similar risk of death (hazard ratio [HR] 0.90, 95% confidence interval [CI] 0.68-1.20; P = 0.482). Squamous VUC, which was the most frequent variant in the cohort, had a comparable ORR, DCR and OS as compared with PUC or non-squamous VUC. The patients with sarcomatoid VUC (n = 19) had significantly better ORR (36.8%, P = 0.031), DCR (52.6%, P = 0.032), and OS (HR 0.37, 95% CI 0.15-0.90; P = 0.023) compared to patients with PUC. CONCLUSIONS: The presence of variant histology did not seem to affect BOR or OS after pembrolizumab administration in patients with chemo-resistant UC. The patients with sarcomatoid VUC achieved favourable responses and survival rates compared to PUC.

BACKGROUND: The Paris System (TPS) for reporting urinary cytology differs from conventional systems (CS) in that it focuses on the diagnosis of high-grade urothelial carcinoma (HGUC). This study investigated the impact of TPS implementation on the diagnostic accuracy of HGUC by comparing it with our institutional CS. METHODS: A total of 649 patients who underwent transurethral resection of bladder tumor (TURBT) between January 2009 and December 2020 were included in this study. Our institution adopted TPS to report urinary cytology in February 2020. The diagnostic accuracy of HGUC in preoperative urinary cytology was compared with the presence or absence of HGUC in resected specimens of TURBT before and after TPS implementation. RESULTS: After implementing TPS in urinary cytology, 89 patients were reviewed and compared with 560 patients whose urinary cytology was diagnosed by CS. TPS and CS for detecting HGUC had 56.0% and 58.2% sensitivity, 97.8% and 91.2% specificity, and 93.3% and 87.9% positive predictive values, respectively. There were no significant differences between TPS and CS in terms of sensitivity, specificity, and positive predictive value for HGUC (P = 0.83, 0.21, 1.00). On the other hand, the negative predictive value for HGUC using TPS was 80.0%, which was significantly higher than that of CS (66.4%, P = 0.04) The multivariate logistic regression analysis indicated that not using TPS was one of the independent predictive factors associated with false-negative results for HGUC (odds ratio, 2.26; 95% confidence interval, 1.08-4.77; P = 0.03). CONCLUSION: In instances where urinary cytology is reported as negative for HGUC by TPS, there is a low probability of HGUC, indicating that TPS has a potential diagnostic benefit.

BACKGROUND: This study investigated the clinical impact of carcinoma in situ (CIS) in intravesical Bacillus Calmette-Guérin (BCG) therapy for patients with non-muscle-invasive bladder cancer (NMIBC). METHODS: This study retrospectively evaluated 3035 patients who were diagnosed with NMIBC and treated by intravesical BCG therapy between 2000 and 2019 at 31 institutions. Patients were divided into six groups according to the presence of CIS as follows: low-grade Ta without concomitant CIS, high-grade Ta without concomitant CIS, high-grade Ta with concomitant CIS, high-grade T1 without concomitant CIS, high-grade T1 with concomitant CIS, and pure CIS (without any papillary lesion). The endpoints were recurrence- and progression-free survival after the initiation of BCG therapy. We analyzed to identify factors associated with recurrence and progression. RESULTS: At a median follow-up of 44.4 months, recurrence and progression were observed in 955 (31.5%) and 316 (10.4%) patients, respectively. Comparison of six groups using univariate and multivariate analysis showed no significant association of CIS. However, CIS in the prostatic urethra was an independent factors associated with progression. CONCLUSION: Concomitant CIS did not show a significant impact in the analysis of Ta and T1 tumors which were treated using intravesical BCG. Concomitant CIS in the prostatic urethra was associated with high risk of progression. Alternative treatment approaches such as radical cystectomy should be considered for patients with NMIBC who have a risk of progression.

INTRODUCTION: We examined the prevalence, pathological findings, and oncological outcomes of incidental bladder cancer found on cystoscopy among patients eligible for prostate biopsy (PB). METHODS: We retrospectively reviewed 803 patients who underwent cystoscopy prior to PB between January 2010 and September 2020. In cases of bladder tumor-like findings on cystoscopy, biopsy or transurethral resection of the bladder tumor was performed. The primary and secondary outcomes were the prevalence of incidental bladder cancer and pathological and oncological outcomes of incidental bladder cancer, respectively. RESULTS: Incidental findings were observed in 31/803 patients (3.9%). Bladder tumor-like findings were found in 24/803 patients (3%), while 9/803 patients (1.1%) were pathologically diagnosed with urothelial carcinoma. The stage and grade of incidental bladder cancer were pTa in 8/9 patients and pT1 in 1/9 and low grade in 8/9 and high in 1/9, respectively. The median tumor size of the papillary pedunculated type was 0.5 cm. At 26-month median follow-up, no recurrence was observed. CONCLUSION: Cystoscopy during PB may yield incidental bladder cancer findings, although the prevalence is very low. Incidental bladder cancer was of low stage and grade, which seemed unrelated to survival. Moreover, performing routine cystoscopy in conjunction with PB is not recommended as it may lead to overdiagnosis of low-risk bladder cancer.

OBJECTIVES: The US Food and Drug Administration recently defined the clinical term "bacillus Calmette-Guérin-unresponsive non-muscle-invasive bladder cancer" as a disease state resistant to adequate bacillus Calmette-Guérin therapy. There is a significant lack of prognostication for this disease even in patients who have undergone early radical cystectomy. This study aimed to identify the clinical outcomes and prognostic factors in Japanese patients with bacillus Calmette-Guérin-unresponsive non-muscle-invasive bladder cancer who underwent early radical cystectomy. METHODS: Data from a large-scale multicenter retrospective study included 2879 patients with highest-risk or high-risk non-muscle-invasive bladder cancer who received intravesical bacillus Calmette-Guérin induction therapy between January 2000 and December 2019. A total of 141 patients (4.3%) met the criteria for bacillus Calmette-Guérin-unresponsive disease, of whom 47 (33.3%) underwent early radical cystectomy. Prognostic factors for three clinical endpoints, namely, unresectable lesion-free survival, cancer-specific survival, and overall survival, were identified. RESULTS: The highest-risk status at induction bacillus Calmette-Guérin was associated with short unresectable lesion-free survival (hazard ratio 7.85; P < 0.05), cancer-specific survival (hazard ratio 12.24; P < 0.05), and overall survival (hazard ratio 9.25; P < 0.01). Moreover, extravesical tumors (pathological T3 or T4) on the radical cystectomy specimens were associated with poor prognosis and were found at a higher rate in patients with the highest-risk status at induction bacillus Calmette-Guérin than in those with high-risk status (35.7% vs 21.2%). CONCLUSIONS: The highest-risk status among the pre-bacillus Calmette-Guérin factors was associated with upstaging to extravesical tumors and poor prognosis despite early radical cystectomy procedures. Appropriate decision-making and the correct timing of radical cystectomy are vital to avoid treatment delays and improve outcomes.

OBJECTIVE: To assess real-world oncological outcomes between the radical cystectomy (RC) group and non-RC group for early relapse and refractory disease. METHODS: We retrospectively analyzed 953 patients with recurrent non-muscle-invasive bladder cancer (NMIBC) who received bacillus Calmette-Guérin (BCG) at 31 affiliated hospitals from 2000 to 2019. Patients with missing data on the timing of failure were excluded and 871 patients remained eligible, of whom 447, 357, and 67 were classified as early relapse/refractory disease, intermediate/late relapse disease, and intolerant disease, respectively. For early relapse/refractory disease, patients were divided into two salvage treatment groups: RC and non-RC. The clinicopathological variables of each group were examined using Kaplan-Meier plots and proportional Cox hazard ratios with matched score analyses to compare oncological outcomes between the two groups. RESULTS: Significantly worse progression-free survival and cancer-specific survival (CSS) were confirmed in the early relapse/refractory disease group compared to the intermediate/late relapse group. Of the 88 salvage patients in the RC group with early relapse/refractory disease, ≤pT1 was observed in 47, pT2 in 11, and ≥pT3 in 28 (two patients with unknown pT category). In early relapse/refractory disease, the RC group showed significantly high-risk tumor compared to the non-RC group. However, no significant difference was observed in CSS after matched score analyses (p = 0.45) between the RC and non-RC groups. CONCLUSIONS: This study found that the RC group showed no significant superiority compared to the non-RC group in CSS for early relapse/refractory disease in terms of first salvage therapy.
