RESUMEN
Background: Photodynamic diagnosis-assisted transurethral resection of bladder tumors (PDD-TURBT) enhances detection of elusive lesions compared to standard white light-transurethral resection of bladder tumors (WL-TURBT). If minimal light exposure during PDD-TURBT induces the accumulation of reactive oxygen species (ROS), potentially resulting in phototoxicity in small lesions, apoptosis may be triggered in residual small tumors, allowing them to escape resection. We investigated the hypothesis of a potential photodynamic therapeutic effect during PDD-TURBT. Methods and Materials: Our study, conducted between January 2016 and December 2020 at Nara Medical University Hospital, focused on a specific emphasis on ROS production. Immunohistochemical analysis for thymidine glycol and N ε -hexanoyl-lysine was performed on 69 patients who underwent 5-aminolevulinic acid-mediated PDD-TURBT and 28 patients who underwent WL-TURBT. Additionally, we incrementally applied the minimal irradiation energy to T24 and UM-UC-3 cells treated with 5-aminolevulinic acid using instruments similar to those used in PDD-TURBT and evaluated intracellular ROS production and phototoxicity. Results: Immunohistochemical analysis revealed a significant increase in production of thymidine glycol and N ε -hexanoyl-lysine within the PDD-TURBT group. In T24 and UM-UC-3 cells treated with 5-aminolevulinic acid and light exposure, immunofluorescent staining demonstrated a dose-dependent increase in intracellular ROS production. In addition, higher irradiation energy levels were associated with a greater increase in ROS production and phototoxicity, as well as more significant decrease in mitochondrial membrane potential. Conclusion: Although the irradiation energy used in PDD-TURBT did not reach the levels commonly used in photodynamic therapy, our findings support the presence of a potential cytotoxic effect on bladder lesions during PDD-TURBT.
RESUMEN
BACKGROUND: The clinical importance of nutrition and inflammation in patients with end-stage renal disease is well established. In this study, we investigated the role of nutritional and inflammatory indicators in the patient outcomes of living donor kidney transplant recipients. METHODS: We included 204 consecutive patients who underwent kidney transplantation at our institute between 2003 and 2022. We retrospectively reviewed medical charts to obtain clinical information. Six nutritional indicators and two inflammatory indicators were assessed. Patient outcomes were investigated, and predictive factors were explored. RESULTS: The median patient age and follow-up period were 48 years and 99 months, respectively. The cohort included patients with preoperative malnutrition and microinflammation. No significant differences in graft survival were identified according to nutritional and inflammatory indicators, whereas the survival index, controlled nutritional status, and C-reactive protein levels were associated with patient survival. The survival index was an independent indicator of survival and death in patients with functioning grafts (P = 0.047 and P = 0.013, respectively). Furthermore, the C-reactive protein level could distinguish between low and high mortality risks in patients with good nutrition (P = 0.019). CONCLUSIONS: Our findings suggest that nutrition and inflammation indicators play important roles in predicting outcomes in living donor kidney transplantation recipients. Further research is warranted to establish optimal management strategies.
RESUMEN
BACKGROUND/AIM: This study investigated the follow-up rate of living kidney donors and explored the factors related to continuous follow-up and remnant renal function, enabling the optimal management of living kidney donors. PATIENTS AND METHODS: We retrospectively evaluated 180 living kidney donors who underwent donor nephrectomies at our institute. Clinical information was obtained from medical charts, and remnant renal function was defined as the estimated glomerular filtration rate 12 months after donor nephrectomy. RESULTS: Overall, 6/180 donors (3.3%) were lost to follow-up within a year, and the follow-up rate gradually declined yearly. Independent risk factors for loss to follow-up included a follow-up period <60 months and graft survival of the recipient (p=0.002 and p=0.043, respectively). Recipient survival was correlated with loss to follow-up; however, this was not significant (p=0.051). Regarding remnant renal function, age ≥60 years, preoperative estimated glomerular filtration rate <74 ml/min/1.73 m2, and a Δsingle-kidney estimated glomerular filtration rate <9.3 ml/min/1.73m2 were independent risk factors for poorly preserved remnant renal function (p=0.036, p<0.0001, and p<0.0001, respectively). Using propensity score matching to adjust for preoperative factors, a Δsingle-kidney estimated glomerular filtration rate <9.3 ml/min/1.73 m2 was the only significant postoperative factor for poorly preserved remnant renal function (p=0.023). CONCLUSION: An increased 5-year follow-up rate could lead to an increase in long-term follow-up, and recipient prognosis may be correlated with the living kidney donor follow-up status. Furthermore, Δsingle-kidney estimated glomerular filtration rate was identified as a factor for establishing the optimal precision follow-up management of living kidney donors.

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.
RESUMEN
Background: Although routine surveillance imaging to examine upper urinary tract urothelial cancer recurrence during follow-up of nonmuscle invasive bladder cancer is recommended, its necessity remains invalidated. A single-institute long-term follow-up cohort study to evaluate the clinical impact of routine surveillance imaging and identify risk factors for upper urinary tract urothelial cancer recurrence after nonmuscle invasive bladder cancer treatment was conducted. Methods and Materials: A retrospective chart review of 864 patients with primary nonmuscle invasive bladder cancer who underwent initial transurethral resection of bladder tumor between 1980 and 2020 was conducted. The opportunities to diagnose its recurrence were examined. Moreover, oncological outcomes included upper urinary tract urothelial cancer recurrence-free survival and overall survival. Results: Of 864 patients, 19 (2.2%) experienced upper urinary tract urothelial cancer recurrence. Among 19 patients, recurrence was detected through routine imaging in 12 (63.2%), cystoscopy in 2 (10.5%), urine cytology in 2 (10.5%), and presence of gross hematuria in 1 (5.3%). All patients had high- or highest-risk NMIBC at diagnosis of primary nonmuscle invasive bladder cancer. On multivariate Fine-Gray proportional regression analyses, a tumor size of ≥30 mm and carcinoma in situ were independently associated with short upper urinary tract urothelial cancer recurrence-free survival (P=0.040 and 0.0089, respectively). Conclusion: Most patients experiencing upper urinary tract urothelial cancer recurrence were diagnosed by routine surveillance imaging, suggesting its clinical importance, especially for patients with nonmuscle invasive bladder cancer accompanied by a tumor size of ≥30 mm and carcinoma in situ.
RESUMEN
BACKGROUND: It is unclear whether a hydrogel spacer can improve quality of life (QOL) in patients undergoing low-dose-rate brachytherapy (LDR-BT) alone or in combination with intensity-modulated radiotherapy (IMRT). METHODS: We enrolled patients with prostate cancer who underwent LDR-BT alone with (n = 186) or without (n = 348) a hydrogel spacer, or underwent LDR-BT in combination with IMRT with (n = 70) or without (n = 217) a hydrogel spacer. QOL was evaluated using Expanded Prostate Cancer Index Composite (EPIC) questionnaires at baseline and 1, 3, 6, 12, and 24 months after implantation. The groups were compared using propensity score matching analysis. RESULTS: Among patients who underwent LDR-BT alone, there were no differences regarding changes in urinary, bowel, sexual, or hormonal domain scores between the spacer and no-spacer groups; however, the dose at the bowel was significantly lower in the spacer group than in the no-spacer group. Among patients who underwent LDR-BT in combination with IMRT, there were no differences regarding changes in urinary, sexual, or hormonal domain scores between the spacer and no-spacer groups. However, the changes in the bowel domain score were significantly lower in the spacer group than in the no-spacer group (p < 0.001). CONCLUSIONS: A hydrogel spacer may not improve impaired urinary, bowel, or sexual QOL in patients undergoing LDR-BT alone. However, in patients undergoing LDR-BT in combination with IMRT, a hydrogel spacer can improve impaired bowel QOL but not sexual or urinary QOL.

A time-course questionnaire survey using the chemotherapy-induced taste alteration scale (CiTAS) was conducted in patients with advanced urothelial carcinoma (UC) treated with systemic chemotherapy and/or immunotherapy. A total of 37 patients receiving systemic therapy with enfortumab vedotin (EV), platinum-based chemotherapy and immune checkpoint inhibitors were included in this study. No significant changes were observed in any of the CiTAS subscales during platinum-based chemotherapy and immune checkpoint inhibitor treatment, while EV therapy induced significant dysgeusia. Among 10 patients treated with EV, dysgeusia was associated with a substantial negative effect on the health-related quality-of-life domains, particularly global health status/QOL (mean ± standard deviation: 52 ± 19 in dysgeusia group vs 89 ± 13 in non-dysgeusia group) and mental component summary (47 ± 5.1 vs 53 ± 2.0). The fatigue symptom score was higher in the dysgeusia group at the post-third cycle of EV (47 ± 16 vs 15 ± 17). Severe dysgeusia can be induced by EV therapy, which is usually not observed in other systemic therapies for advanced UC.
RESUMEN
BACKGROUND/AIM: Botulinum toxin intravesical injection therapy (hereafter, botulinum therapy) is approved in Japan for treating urinary urgency, frequency, and urinary incontinence due to refractory overactive bladder or neurogenic bladder. Although botulinum therapy is classified as urinary incontinence surgery, it is minimally invasive, effective, and safe. However, there are few reports on the actual use of botulinum therapy and examination of its effects and side-effects. Herein, we report real-world data on botulinum therapy. PATIENTS AND METHODS: Patients who received botulinum therapy for refractory overactive bladder at the Nara Medical University and affiliated facilities from May 2020 to May 2022 were enrolled. The patient background, treatment efficacy, and safety were retrospectively reviewed. RESULTS: Twenty-three cases of refractory overactive bladder (age: 68.4±14.1 years; 7 males, 16 females; 17 outpatient, 6 hospitalized) were enrolled. Pretreatment, the overactive bladder symptom score (OABSS) was 10.1±2.7, and post-void residual urine volume was 27.1±31.6 ml. Botulinum was administered once, twice, thrice, and four times in 11, eight, three, and one cases, respectively. OABSS decreased to 6.1±3.2 2 weeks after botulinum therapy (p<0.0001), and the effect persisted at 6.6±3.2 after 12 weeks (p<0.0001). Post-void residual urine volume increased to 74.6±79.2 ml after 2 weeks (p=0.0010), but subsequently improved to 33.9±42.0 ml after 12 weeks (p=0.0002). Adverse events included post-void residual urine volume of 200 ml or more in three patients (7.5%) and urinary retention grade 2 in two (5.0%). CONCLUSION: Botulinum therapy is effective and relatively safe for refractory overactive bladders.

AIMS: To investigate changes in subjective and objective sleep quality after desmopressin administration in patients with nocturia due to nocturnal polyuria (NP) using electroencephalography (EEG) and the Pittsburgh sleep quality index (PSQI). METHODS: Twenty male patients (≥65 years old) with NP participated in this study. The inclusion criteria were nocturnal frequency ≥ 2, NP index (NPi) ≥ 0.33, first uninterrupted sleep period (FUSP) ≤ 2.5 h, serum sodium concentration ≥ 135 mEq/L, and estimated glomerular filtration rate ≥ 50 mL/min/1.73 m2. Participants were given 50 µg of desmopressin to be taken orally once daily before bed. The primary endpoint was the change in the duration of slow-wave sleep (nonrapid eye movement sleep stages 3 and 4), as evaluated by EEG 28 days from the baseline. The visual analog scale (VAS) was used as an additional indicator of sleep quality. RESULTS: Analysis of data from 15 participants (median age: 74.0 [70.5, 76.0] years) revealed that from before to after desmopressin administration, significant decreases occurred in the median nocturnal frequency (3.0 [2.0, 4.0] to 1.5 [1.0, 2.0]) and NPi (0.445 [0.380, 0.475] to 0.360 [0.250, 0.430]). Furthermore, FUSP was significantly prolonged from 120.0 (94.0, 150.0) min to 210.0 (203.8, 311.3) min. Although the VAS scores improved, slow-wave sleep duration and the PSQI global score showed no significant differences (68.50 [47.50, 75.50] and 48.00 [38.00, 66.50]; 5.0 [5.0, 10.0] and 7.0 [5.0, 9.0] min, respectively). CONCLUSION: Oral administration of 50 µg desmopressin improved nocturnal frequency and FUSP in older individuals with NP but did not significantly enhance sleep quality. In older adults, decreased nighttime urinary frequency may enhance quality of life; however, its influence on objective sleep quality may be limited.
RESUMEN
Introduction: Patients with trisomy 13 have multiple malformations, including urological anomalies, and severe cognitive and psychomotor disabilities. We conducted a ureteroureterostomy for a mid-ureteral stricture due to a retroiliac ureter in a patient with trisomy 13. Case presentation: A 6-month-old girl with trisomy 13 developed a urinary tract infection. Computed tomography for assessing recurrent urinary tract infection revealed a left mid-ureteral stricture due to the retroiliac ureter. At the age of 2, a ureteroureterostomy was performed. Two years after surgery, the urinary tract infection did not recur. Conclusion: Ureteroureterostomy is a safe procedure for children with trisomy 13 and multiple comorbidities. Surgical treatment should be considered for patients with trisomy 13 when agreed upon by the family and comorbidities are well-controlled.
RESUMEN
Complete metastasectomy (CM) in metastatic renal cell carcinoma (mRCC) has demonstrated efficacy in the cytokine era, but its effectiveness in the era of tyrosine kinase inhibitors (TKIs) and immune checkpoint inhibitors (ICIs) remains unclear. A multi-institutional database included clinicopathological data of 367 patients with mRCC. Patients were divided into two groups: the CM group and the non-CM group. These two groups were compared before and after propensity score matching (PSM). Cox proportional hazard models were used to detect factors associated with disease-free survival (DFS) and overall survival (OS) from mRCC diagnosis. The CM group showed a significant association with longer overall survival compared to the non-CM group in the PSM-unadjusted cohorts (p < 0.001, hazard ratio 0.49, 95% confidence interval 0.35-0.69), but no superiority was noted in the adjusted cohorts. The median DFS after CM was 24 months, with no significant differences based on relapse timing. Notably, the international metastatic RCC database consortium risk categories and metastatic burden were associated with DFS. This study supports the potential of CM in mRCC management during the TKI/ICI era, although limitations including sample size and selection bias need to be considered.
RESUMEN
OBJECTIVES: Many congenital hydronephroses spontaneously resolve. This study evaluated a long-term follow-up of more than 4 years of patients with congenital hydronephrosis at a single center. METHODS: In total, 215 patients (286 kidneys) with congenital hydronephrosis were included. Hydronephrosis outcomes (resolution, improvement, and persistence) and time-to-outcome were evaluated. RESULTS: Fourteen patients underwent early surgical intervention until the age of 2 years. A total of 189 congenital hydronephrosis cases (66%) showed resolution at a median of 16 months (interquartile range: 7-21 months) and 169 (80%) of 210 kidneys with grade I to II hydronephrosis showed resolution at a median of 14 months (interquartile range: 6-23 months). Of 76 kidneys with grade III to IV hydronephrosis, 24 (32%) showed resolution at a median of 29 months (interquartile range: 24-41 months), and 56 (74%) showed improvement to grade II or less at a median of 12 months (interquartile range: 5-23 months). Of the 76 kidneys with grade III to IV hydronephrosis, five required delayed pyeloplasty at a median of 66 months (interquartile range: 42-89 months). One patient was asymptomatic, with a marked worsening of hydronephrosis and decreased renal function 6 years after the resolution of hydronephrosis. CONCLUSIONS: None of the patients with grade I to II hydronephrosis required surgical treatment, and a shorter follow-up may be sufficient. Grade III to IV severe hydronephrosis should be considered for a longer and more careful follow-up, given the possibility of asymptomatic exacerbation of hydronephrosis.

PURPOSE: There is significant lack on evidence regarding the effect of non-adherence to a recommended protocol in follow-up of high-risk non-muscle-invasive bladder cancer (NMIBC), or the impact of delaying detection of recurrent lesion. Here, we aimed to investigate the optimal frequency of follow-up cystoscopy of high-risk NMIBC with respect to oncological safety in the Japanese real-world clinical practice. METHODS: This retrospective single-center study included 206 patients with primary high-risk NMIBC. The intensity (%) of follow-up cystoscopy was calculated based on actual visits for cystoscopy and guideline-recommended frequency in the first 24-month follow-up period. Inverse probability of treatment weighting analyses was used to reduce the risk of bias between groups. We performed a restricted cubic spline analysis with knots at intensity of follow-up cystoscopy ≤ 100% group to examine the possible association of progression risk with the intensity of follow-up as a continuous exposure. RESULTS: The median intensity was 87.5% (interquartile range, 75-100). Adjusted multivariate analysis for MIBC-free and progression-free survival demonstrated no significant difference between adjusted ≤ 75% and > 75% intensity groups. A restricted cubic spline analysis suggested no significant effect of the intensity of follow-up on progression risk, and hazard ratios of patients of < 100% intensity were equivalent to those of patients of 100% intensity. CONCLUSION: Our finding suggested decreased intensity of follow-up cystoscopy did not affect oncological outcomes in patients with high-risk NMIBC. Further prospective trials directly aimed at investigating optimized follow-up schedules for NMIBC are mandatory before substantial changes to existing clinical guidelines.

OBJECTIVES: Cryptorchidism (CO) diagnosis by palpation is challenging. Patients with suspected CO are primarily referred to pediatric urologists by general pediatricians and urologists. Currently, surgical treatment for CO is recommended earlier than in previous guidelines. In this study, we evaluated factors that lead to diagnosis discordance and delayed orchidopexy in patients referred with suspected CO in addition to timing of initial screening. METHODS: In total, 731 patients (1052 testes) with suspected CO were included. Risk factors for diagnostic discrepancy in CO diagnosis by pediatric urologists and risk of delayed orchiopexy were evaluated. RESULTS: Herein, 659 (90%) patients were diagnosed during routine public health checkups for infants and young children, and 419 (57%) patients were referred by pediatric practitioners. Of 1052 testes, 374 (36%) were diagnosed with CO by pediatric urologists. In multivariate analysis, risk factors of diagnostic discrepancy for CO diagnosis by pediatric urologists were bilateral testis (odds ratio [OR] = 9.17, p < 0.0001), >6 months old at initial diagnosis (OR = 1.036, p < 0.0001), and pediatric referral (OR = 4.60, p < 0.0001). In total, 296 patients underwent orchiopexy for CO. In multivariate analysis, risk factors for delayed orchiopexy were presence of comorbidities (OR = 3.43, p = 0.003) and >10 months old at referral (OR = 12.62, p < 0.0001). CONCLUSIONS: Pediatric referral is a risk factor for discordant CO diagnostics, and late age at referral brings a risk of delayed orchiopexy. It is necessary to enlighten pediatricians, who are mainly responsible for routine health checkups, in teaching CO diagnostic techniques to ensure early referral.

OBJECTIVE: To evaluate quality of life (QOL) after non-nerve-sparing, robot-assisted radical prostatectomy (RARP) and factors associated with worsened QOL. METHODS: Patients who underwent non-nerve-sparing RARP (n = 115) were enrolled. The Expanded Prostate Cancer Index Composite and 8-item Short Form Health Survey were used to evaluate QOL at baseline and postoperative 1, 3, 6, 12, and 24 months. Preoperative factors were evaluated by multivariate analysis for worsened QOL. RESULTS: Postoperative 24-month urinary QOL worsened in 68 of 115 (59%) patients. In multivariate analysis, membranous urethral length ≥10.8 mm [odds ratio (OR): .26, 95% confidence interval (CI): .07-.96] and intravesical prostatic protrusion ≥12 mm (OR: .14, 95% CI .06-.35) were significantly associated with maintaining postoperative 24-month urinary QOL. Significantly more patients with intravesical prostatic protrusion ≥12 mm than < 12 mm had improved urinary QOL. At postoperative 24 months, 43 of 115 (38%) patients had worsened sexual QOL. In multivariate analysis, higher Sexual Health Inventory for Men score (OR: 8.39, 95% CI 2.28-30.9), sexual activity (OR: 6.94, 95% CI: 2.27-21.2), and intercourse activity (OR: 6.81, 95% CI: 1.64-28.3) preoperatively were significantly associated with worsened postoperative 24-month sexual QOL. More patients with high preoperative intercourse activity (12/23,53%) had significantly worsened (p = .009) QOL regarding sexual bother than those who had no preoperative intercourse activity (21/92, 23%). CONCLUSION: After non-nerve-sparing RARP, patients with long membranous urethral length and/or intravesical prostatic protrusion maintain urinary QOL. Patients with high intercourse activity presented with impairment of sexual QOL after non-nerve-sparing RARP.

BACKGROUND: The clinical significance of nutrition and inflammation in dialysis patients is well established. This study aimed to evaluate the association between prognosis and indicators of nutrition and inflammation. METHODS: A total of 253 consecutive patients who underwent peritoneal dialysis (PD) as primary renal replacement therapy at our institute between 2006 and 2021 were included. We retrospectively reviewed the patient's medical charts and obtained their clinical information. Nine nutritional and two inflammatory indicators were assessed. Patient outcomes were investigated, and predictive factors were explored. RESULTS: The median age and follow-up period were 65 years and 54 months, respectively. Most nutritional indicators and C-reactive protein (CRP) levels showed a significant correlation with residual renal function. Multivariate analysis revealed that the survival index, nutritional risk index for Japanese hemodialysis patients, and CRP levels were independent indicators of patient survival (P < 0.001, P = 0.034, and P = 0.005, respectively) and cardiovascular disease-free survival (P = 0.009, P = 0.04, and P = 0.017, respectively). Patients with a survival index < 19 and CRP ≥ 0.5 had a high risk of mortality and cardiovascular death (P < 0.0001 and P = 0.0002, respectively). CONCLUSIONS: Our findings suggest that indicators of nutrition and inflammation play important roles in predicting patient outcomes. Further research is warranted to establish optimal management strategies for patients on PD.

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.

Background: Radical cystectomy (RC) is the standard surgical treatment for patients with muscle-invasive bladder cancer, but the prognosis is not favorable, and new prognostic factors need to be discovered. We investigated the potential of depth of invasion (DOI) as a prognostic factor in patients with muscle-invasive bladder cancer who underwent RC. Furthermore, we examined the association between preoperative levels of circulating cell-free DNA and DOI. Materials and methods: We retrospectively reviewed patients who underwent RC between January 2007 and December 2017; those who received neoadjuvant chemotherapy were excluded. Depth of invasion was measured using hematoxylin-eosin-stained RC specimens. Results: Of the 121 patients selected, 41 (33.9%) were eligible for analysis. The median follow-up period was 14 months and mean DOI was 17 mm (range, 2-75 mm). Long DOI (>17 mm) was significantly associated with shorter progression-free survival (hazard ratio, 14.5; 95% confidence interval, 3.9-53.97, p < 0.0001) and cancer-specific survival (hazard ratio, 18.97; 95% confidence interval, 4.04-88.99, p = 0.0002) compared with short DOI. Multivariate analysis revealed that DOI was an independent risk factor for cancer-specific survival. The levels of circulating cell-free DNA were significantly higher in patients with a longer DOI than in those with short DOI (65 vs. 20 ng/mL, respectively; p = 0.028). Conclusions: Depth of invasion predicted with levels of circulating cell-free DNA and thus could be a useful prognostic factor.
