ABSTRACT
BACKGROUND: Controversial issues in registering candidates for deceased-donor kidney transplantation (DDKT) comprise various factors, including age, life expectancy, and dialysis duration. We investigated patient characteristics on the waiting list and discussed suitable criteria in Japan, which has a long waiting period. METHODS: This study included 592 patients on the waiting list for DDKT at our institute between 1982 and 2023. We retrospectively reviewed patients' medical charts and obtained their clinical information. Patient characteristics according to outcomes and eligibility criteria for applying for or renewing registration were investigated. No prisoners were used in the study, and the participants were neither coerced nor paid. RESULTS: Approximately 70%, 45%, and 14.5% of the registered patients were aged >60, >70, and 80 years, respectively. The number of patients aged ≥70 years gradually decreased over time. The median waiting periods of patients who underwent and interrupted DDKT were 13 and 7 years, respectively. Patients in their 70s with a >15-year dialysis period tended to have opportunities for DDKT. Living-donor kidney transplantation was performed in patients aged <60 years. Waiting patients were significantly younger and had a shorter dialysis duration. Advanced age at registration was associated with a significantly high risk of interruption. CONCLUSIONS: Advanced age and longer dialysis periods were considered at registration because patients with these factors tended to experience interruptions despite the long waiting period and high cost. Although older patients can undergo DDKT, factors including surgical cost and risks are considered. Eligibility/ineligibility criteria should be established for DDKT waiting lists in Japan.
ABSTRACT
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.
ABSTRACT
BACKGROUND: Urinary dysfunction is an adverse event of low-dose-rate brachytherapy (LDR-BT) in patients with prostate cancer. We aimed to examine the time to α-1 adrenergic antagonist withdrawal after LDR-BT initiation. METHODS: We retrospectively evaluated 1663 patients who underwent LDR-BT at our hospital during 2004-2022. RESULTS: Overall, 1485/1663 (89.3%) patients were able to stop using α-1 adrenergic antagonists, 1111 (66.8%) of them within 1 year of LDR-BT. Risk factors for prolonged time to withdrawal were age ≥70 years, taking agents for lower urinary tract symptoms prior to LDR-BT, an International Prostate Symptom Score ≥8, an Overactive Bladder Symptom Score ≥3 and a residual urine volume ≥20 ml. Of the patients who were able to stop taking α-1 adrenergic antagonists, 357/1485 (24.0%) required resumption, 218 (61.1%) of whom did so between 1 and 3 years after LDR-BT. This period matched the period of transient worsening of the urinary symptom score. Finally, multivariable analysis identified supplemental external beam radiotherapy and an Overactive Bladder Symptom Score ≥3 as independent risk factors for α-1 adrenergic antagonist resumption. CONCLUSIONS: Withdrawal of α-1 adrenergic antagonists was possible in 66.8% of patients within 1 year of LDR-BT. Our results suggest that patients who are older or have pre-treatment LUTS may have prolonged deterioration of urinary dysfunction after treatment. Resumption of α-1 adrenergic antagonists 1-3 years after treatment may be associated with urinary symptom flares, and close attention is necessary for patients with supplemental external beam radiotherapy and a high pretreatment Overactive Bladder Symptom Score.
ABSTRACT
Unresectable, metastatic, advanced urothelial carcinoma (aUC) is an aggressive disease and is treated with platinum-containing first-line chemotherapy, followed by immune checkpoint inhibitors and antibody-drug conjugates. Response to first-line chemotherapy is a vital priority in sequential treatment strategies because a better response to first-line chemotherapy is associated with a better response to subsequent therapies. Gemcitabine plus carboplatin chemotherapy is conventionally recommended for cisplatin-ineligible patients. This multicenter, single-arm prospective trial will investigate whether dose-dense methotrexate, vinblastine, doxorubicin, and carboplatin (DD-MVACarbo) chemotherapy is superior to gemcitabine plus carboplatin chemotherapy in terms of efficacy in platinum-naïve, cisplatin-ineligible patients with aUC. After screening and registration, a total of 46 patients will be treated with this novel chemotherapy regimen. The primary endpoint is the objective response rate. The secondary endpoints include disease control rate, patient-reported outcomes, and adverse events. No evidence of this novel intervention is available as of July 2024. The results are expected to change the standard of care and improve the management of patients with aUC.
ABSTRACT
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.
ABSTRACT
BACKGROUND: The therapeutic role of pelvic lymph node dissection (PLND) during radical prostatectomy (RP) for prostate cancer is not established. In clinical practice, PLND is primarily performed in cases of high-risk prostate cancer. The detection of lymph node metastasis plays a crucial role in determining the need for subsequent treatments. This study aims to evaluate the prognosis of prostate cancer patients with lymph node involvement (LNI) by stratifying them based on postoperative prostate-specific antigen (PSA) levels to identify biomarkers that can guide postoperative treatment strategies. METHODS: Analysis was conducted on 383 patients, selected from 572 initially eligible, who underwent RP with LNI across 33 Japanese Urological Oncology Group institutions from 2006 to 2019. Patients were grouped according to postoperative PSA levels and salvage treatments received. Follow-up focused on castration resistance-free survival (CRFS), metastasis-free survival (MFS), and overall survival (OS). RESULTS: In the persistent PSA group (PSA ≥ 0.1 ng/mL), CRFS and MFS were significantly shorter compared to the non-persistent PSA group (PSA < 0.1 ng/mL), and there was a tendency for shorter OS. In the persistent PSA group, patients with postoperative PSA values above the median (PSA ≥ 0.52 ng/mL) showed shorter CRFS and MFS. Furthermore, in the PSA ≥ 0.52 group, androgen deprivation therapy (ADT) plus radiotherapy (RT) combination had prolonged CRFS and MFS compared with ADT alone. CONCLUSIONS: This study provides valuable insights into stratifying patients based on postoperative PSA levels to tailor postoperative treatment strategies, potentially improving the prognosis of prostate cancer patients with LNI.
ABSTRACT
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.

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.

OBJECTIVES: In a primary analysis of data from the BRIGHT study (UMIN000035712), photodynamic diagnosis-assisted transurethral resection of bladder tumor (PDD-TURBT) using oral 5-aminolevulinic acid hydrochloride reduced residual tumors in high-risk non-muscle invasive bladder cancer (NMIBC). We aimed to evaluate the effectiveness of PDD-TURBT for intravesical recurrence after a second transurethral resection for high-risk NMIBC. METHODS: High-risk NMIBC patients initially treated with PDD-TURBT (PDD group) were prospectively registered between 2018 and 2020. High-risk patients with NMIBC who were initially treated with white-light TURBT (WL group) were retrospectively registered. Intravesical recurrence-free survival after the second transurethral resection was compared between the PDD and WL groups using propensity score matching analysis. RESULTS: In total, 177 patients were enrolled in the PDD group, and 306 patients were registered in the WL group. After propensity score matching (146 cases in each group), intravesical recurrence within 1 year was significantly less frequent in the PDD group than in the WL group (p = 0.004; hazard ratio [HR] 0.44, 95% confidence interval [CI]: 0.25-0.77). In subgroup analysis, PDD-TURBT showed a particularly high efficacy in reducing intravesical recurrence within 1 year, especially in cases of tumors measuring less than 3 cm (p = 0.003; HR 0.31, 95% CI: 0.14-0.67), absence of residual tumor at second transurethral resection (p = 0.020; HR 0.37, 95% CI: 0.16-0.86), and no postoperative intravesical Bacillus Calmette-Guérin therapy (p < 0.001; HR 0.27, 95% CI: 0.13-0.58). CONCLUSIONS: PDD-TURBT may reduce short-term intravesical recurrence in patients with high-risk NMIBC.

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.
ABSTRACT
FAN score is reportedly associated with prognostic outcomes in patients with urothelial carcinoma being treated with immune check point inhibitors. However, the prognostic impact of pre-treatment FAN score in patients with metastatic renal cell carcinoma (RCC) treated with nivolumab plus ipilimumab remains unclear. We retrospectively evaluated the association between pre-treatment FAN score and prognostic outcomes in 154 patients with metastatic RCC treated with nivolumab plus ipilimumab. The pre-treatment FAN score was '0' in 56 patients (36%), '1' in 60 patients (40%), '2' in 37 patients (24%) and '3' in one patient (1%). Progression-free survival was not significantly different between patients with different FAN scores, but second progression-free survival (PFS2), cancer-specific survival (CSS) and overall survival (OS) were significantly different. In multivariable Cox proportional hazard analyses, FAN score ≥ 2 was a significant predictor of poor PFS2 (vs. FAN score 0, HR: 2.43, 95% CI 1.21-4.87, P = 0.01), poor CSS (vs. FAN score 0, HR: 2.71, 95% CI 1.13-6.47, P = 0.02) and poor OS (vs. FAN score 0, HR: 2.42, 95% CI 1.11-5.25, P = 0.02). High pre-treatment FAN score could be a significant independent predictor of poor prognosis in patients receiving nivolumab plus ipilimumab for metastatic RCC.

The process and molecular mechanisms underlying the formation and destruction of a pseudo-capsule (PC) in clear cell renal cell carcinoma (ccRCC) are poorly understood. In the present study, the PCs of surgical specimens from primary tumors and metastatic lesions in 169 patients with ccRCC, and carcinogen-induced ccRCC rat models were semi-quantified using the invasion of PC (i-Cap) score system. This was based on the relationship among the tumor, PC and adjacent normal tissue (NT) as follows: i-Cap 0, tumor has no PC and does not invade NT; i-Cap 1, tumor has a complete PC and does not invade into the PC; i-Cap 2, tumor with focal absences in the PC, which partially invades the PC but not completely through the PC; i-Cap 3, tumor crosses the PC and invades the NT; i-Cap 4, tumor directly invades the NT without a PC. The study suggested that PC formation was not observed without physical compression, and also revealed that tumor invasion into the PC was a prognostic factor for postoperative oncological outcomes. Higher i-Cap, Fuhrman grade and tumor size were independent poor prognostic factors for postoperative disease-free survival. mRNA expression arrays generated from carcinogen-induced ccRCC rat models were used to explore genes potentially associated with the formation and destruction of a PC. Subsequently, human ccRCC specimens were validated for four genes identified via expression array; the results revealed that collagen type 4A2, matrix metalloproteinase-7 and l-selectin were upregulated alongside the progression of i-Cap score. Conversely, endoglin was downregulated. In conclusion, the present study provides insights into the formation and destruction of a PC, and the results may aid the treatment and management of patients with ccRCC.
ABSTRACT
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.

OBJECTIVES: The aim of this study was to compare clinical outcomes between patients receiving second TUR after initial white-light transurethral resection of bladder tumor (WL-TURBT) and initial photodynamic diagnosis (PDD)-assisted TURBT. METHODS: A total of 1007 patients were divided into four groups based on the treatment pattern: WL-TURBT with second TUR (161 patients, WL-second group) or without second TUR (540 patients, WL-alone group) and PDD-TURBT with second TUR (112 patients, PDD-second group) or without second TUR (194 patients, PDD-alone group). Oncologic outcomes (bladder cancer recurrence, progression, urothelial cancer-specific mortality) and rates of residual tumor and risk stratification of non-muscle-invasive bladder cancer (NMIBC) after second TUR were evaluated. RESULTS: After propensity score-matching 121 patients were included each in the WL-alone and WL-second groups, and 63 patients each in the PDD-alone and PDD-second groups. In the WL group, the second TUR was significantly associated with improved progression-free (p = 0.012) and urothelial cancer-specific free survival (p = 0.011), but not with recurrence-free survival (p = 0.93). Patients initially treated with PDD-TURBT, and with a tumor diameter <30 mm and multifocality had a relatively high benefit from second TUR. The rates of residual tumor and risk stratification of NMIBC did not significantly differ between WL-TURBT and PDD-TURBT groups. CONCLUSIONS: Our findings suggested that a second TUR could be omitted after an initial PDD-TURBT in selected patients with high-risk NMIBC.

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.

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.
ABSTRACT
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.
