RESUMEN
BACKGROUND: Enfortumab vedotin (EV) was approved for patients with metastatic urothelial carcinoma (mUC) who progressed after anticancer therapy on September 2021 in Japan. The association between the occurrence of EV-related side effects and clinical outcome remains to be elucidated. METHODS: We identified 97 mUC patients treated with EV therapy at our five institutions from the date of approval to March 2023. The median follow-up period was 7.0 months. We retrospectively analyzed the efficacy and safety of EV. RESULTS: The median age of the patients was 71 years old, 39% had PS of 1 or more, and 56.7% had primary tumor in upper urinary tract. Overall response rate (ORR) to EV therapy, median progression-free survival (PFS), and overall survival (OS) were 43.3%, 7.52 months, and 12.78 months, respectively. Any grade of treatment-related skin disorder, dysgeusia, peripheral neuropathy, gastrointestinal disorder, and hyperglycemia occurred in 61 (62.9%), 36 (37.1%), 34 (35.1%), 29 (29.9%), and 18 (18.6%) patients, respectively. The patients with EV-associated peripheral neuropathy had significantly higher ORR (58.8% vs. 34.9%, P = .032) and longer median PFS (8.05 vs. 6.31 months, P = .017) and OS (not reached vs. 11.57 months, P = .008, respectively) than those without. The occurrence of peripheral neuropathy after EV treatment and the presence of peritoneal dissemination were factors independently associated with PFS (hazard ratio = 0.46, P = .008 and hazard raito = 3.83, P = .004, respectively) and OS (hazard ratio = 0.30, P = .005 and hazard raito = 4.53, P = .002, respectively). CONCLUSIONS: The occurrence of EV-related peripheral neuropathy might be associated with the efficacy of EV therapy in mUC patients.
RESUMEN
BACKGROUND: Among patients with non-muscle-invasive bladder cancer (NMIBC), systematic reviews showed lower recurrence rate in patients treated with photodynamic diagnosis (PDD)-assisted transurethral resection of bladder tumor (TURBT) than with white-light (WL) TURBT. However, the result is not consistent between clinical trials and the significance of preoperatively available factors in disease recurrence after PDD-TURBT remains unclear. METHODS: The present study retrospectively analyzed 1174 NMIBC patients who underwent TURBT and were followed up for ≥ 6 months. Among 1174 patients, 385 and 789 underwent PDD-TURBT with oral 5-aminolevulinic acid (the PDD group) and WL-TURBT (the WL group), respectively. Recurrence-free survival (RFS) was compared between the PDD and WL groups before and after propensity score matching, and the impact of several baseline parameters on RFS between the 2 groups was investigated after matching. RESULTS: Before propensity score matching, RFS was significantly longer in the PDD group than in the WL group (P = 0.006). After matching, 383 patients were included in both groups, and RFS was significantly longer in the PDD group than in the WL group (P < 0.001). In the cohort after matching, RFS between the two groups was compared in each subgroup classified according to baseline parameters, including age, sex, history of previous or concomitant upper urinary tract urothelial carcinoma, preoperative urinary cytology, tumor multiplicity, and tumor size, and significantly longer RFS was observed in the PDD group in all subgroups, except for the patients with tumors ≥ 30 mm (P = 0.21). CONCLUSION: These results suggest that PDD-TURBT prolongs RFS in NMIBC patients, except for those with tumors ≥ 30 mm.

BACKGROUND: A useful biomarker for the efficacy of immune checkpoint inhibitors (ICIs) in advanced renal cell carcinoma (RCC) has not yet been established. This study aims to investigate whether inflammatory markers are associated with the efficacy of nivolumab plus ipilimumab therapy before and during treatment. METHODS: Data from patients with advanced clear cell RCC who received a combination treatment of nivolumab plus ipilimumab were retrospectively analyzed. The neutrophil-to-lymphocyte ratio (NLR), monocyte-to-lymphocyte ratio (MLR), platelet-to-lymphocyte ratio (PLR), and C-reactive protein (CRP) levels were assessed at baseline and 3, 6, and 9 weeks after treatment initiation. The correlation between these inflammatory markers and the patient's prognosis was investigated. RESULTS: Eighty-four patients were identified. The multivariate analysis identified NLR at week 3, CRP at week 6, and NLR and CRP at week 9 as the consistent predictor associated with poor overall survival (OS) at each time point. The survival analysis and receiver operating characteristic (ROC) curve analysis revealed that an NLR of ≥ 2.4 at week 3, CRP of ≥ 1.4 mg/dL at week 6, and NLR of ≥ 4.8 and CRP of ≥ 1.0 mg/dL at week 9 were associated with worse OS (hazard ratios (HR) = 5.70, P = 0.008, HR = 3.23, P = 0.004, HR = 7.38, P < 0.001 and HR = 3.55, P = 0.002). CONCLUSIONS: Both NLR and CRP were considered useful biomarkers for understanding the prognosis during nivolumab plus ipilimumab therapy. Furthermore, an NLR of ≥ 4.8 and CRP of ≥ 1.0 mg/dL at week 9 are helpful in reconsidering treatment continuation.
RESUMEN
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.

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.

Effective tumor immunotherapy requires physical contact of T cells with cancer cells. However, tumors often constitute a specialized microenvironment that excludes T cells from the vicinity of cancer cells, and its underlying mechanisms are still poorly understood. DOCK2 is a Rac activator critical for migration and activation of lymphocytes. We herein show that cancer-derived cholesterol sulfate (CS), a lipid product of the sulfotransferase SULT2B1b, acts as a DOCK2 inhibitor and prevents tumor infiltration by effector T cells. Using clinical samples, we found that CS was abundantly produced in certain types of human cancers such as colon cancers. Functionally, CS-producing cancer cells exhibited resistance to cancer-specific T-cell transfer and immune checkpoint blockade. Although SULT2B1b is known to sulfate oxysterols and inactivate their tumor-promoting activity, the expression levels of cholesterol hydroxylases, which mediate oxysterol production, are low in SULT2B1b-expressing cancers. Therefore, SULT2B1b inhibition could be a therapeutic strategy to disrupt tumor immune evasion in oxysterol-non-producing cancers. Thus, our findings define a previously unknown mechanism for tumor immune evasion and provide a novel insight into the development of effective immunotherapies.

BACKGROUND: Immune-related adverse events (irAEs) in patients treated with immune check inhibitors are associated with favourable response rate and survivals in multiple cancers, including renal cell carcinoma (RCC). The aim of this study was to investigate how irAEs were associated with improved survivals in advanced RCC patients treated with nivolumab plus ipilimumab. MATERIALS AND METHODS: This retrospective study included patients who received nivolumab plus ipilimumab at six centres, institutions, or hospitals between September 2018 and February 2022. We assessed associations of the development and the number of irAEs with overall survival (OS) and progression-free survival (PFS). To eliminate immortal time bias, landmark analysis and a Cox model with time-dependent variables were used. RESULTS: This study included 129 patients with a median follow-up of 12.3 months. The 2-year OS and PFS rates were 55% and 42%, respectively. Ninety six patients experienced irAEs. The development of irAEs was positively associated with OS and PFS rates (hazard ratio [HR] 0.328, 95% confidence interval [CI] 0.165-0.648, p = 0.001; HR 0.334, 95% CI 0.151-0.737, p = 0.007). Patients who experienced multiple irAEs had longer OS (HR 0.507, 95% CI 0.235-1.097, p = 0.085 or HR 0.245, 95% CI 0.110-0.544, p < 0.001) and PFS (HR 0.572, 95% CI 0.316-1.036, p = 0.085 or HR 0.267, 95% CI 0.113-0.628, p = 0.002) compared with those who experienced single or zero irAE. CONCLUSIONS: Developing irAEs, particularly multiple irAEs, is associated with favourable survivals in advanced RCC patients treated with nivolumab plus ipilimumab.

OBJECTIVES: Although nivolumab plus ipilimumab has become a standard treatment regimen for metastatic clear cell renal cell carcinoma (ccRCC), its efficacy in non-clear cell carcinoma (nccRCC) has not been fully examined. In the current study, we evaluated the clinical outcomes of nivolumab plus ipilimumab in nccRCC compared with ccRCC. METHODS: We retrospectively analyzed 22 patients with metastatic and/or locally advanced unresectable nccRCC who received nivolumab plus ipilimumab as a first-line therapy and compared them with 107 patients with ccRCC. Objective response rate (ORR), progression-free survival (PFS), overall survival (OS), and toxicity were compared between the nccRCC and ccRCC groups. RESULTS: The histology of nccRCC included eight papillary, six unclassified, three chromophobe, two collecting duct carcinoma, and three other subtypes. Best objective response in nccRCC patients included three complete responses and five partial responses, resulting in an ORR of 36%, while that in ccRCC patients was 50% (p = 0.22). With a median follow-up of 11.9 months, OS was significantly shorter in patients with nccRCC than in those with ccRCC (median 20.8 months vs. not reached, p = 0.04), while there was no significant difference in PFS (median 6.3 vs. 10.8 months, p = 0.21). Treatment-related adverse events occurred in 14 (64%) nccRCC patients and 81 (76%) ccRCC patients. CONCLUSIONS: Combination treatment with nivolumab and ipilimumab demonstrated modest clinical efficacy in patients with nccRCC compared with patients with ccRCC, suggesting it could be a therapeutic option for metastatic nccRCC patients.

OBJECTIVES: Bladder cancer, especially non-muscle invasive bladder cancer (NMIBC), is one of the most costly cancers owing to its long-term management. Photodynamic diagnosis-assisted transurethral resection of bladder tumor (PDD-TURBT) reduces the risk of intravesical recurrence. However, its impact on healthcare economics in Japan remains unclear. We evaluated the comprehensive medical costs of Japanese healthcare economics regarding PDD-TURBT. METHODS: This large-scale, multicenter, retrospective study included a dataset of 1531 patients who were diagnosed with primary NMIBC who underwent initial TURBT between April 2006 and June 2021. A one-to-one propensity-score matching analysis was used for an unbiased comparison based on postTURBT follow-up periods. The total medical costs, including hospitalization, surgical procedures for TURBT and salvage radical cystectomy, adjuvant intravesical therapies, and follow-up examinations, were compared between white light (WL)-TURBT and PDD-TURBT groups. RESULTS: After propensity-score matching, 468 patients each of WL- and PDD-TURBT groups were matched. Total costs were 510 337 128 and 514 659 328 ¥ in WL- and PDD-TURBT groups, respectively. The costs of adjuvant intravesical therapies, follow-up examinations, and salvage radical cystectomy in PDD-TURBT group were equivalent to or lower than those in WL-TURBT group. Furthermore, total costs of high- and highest-risk NMIBC in PDD-TURBT group were either equivalent or lower compared to those in WL-TURBT group. CONCLUSIONS: The total costs associated with PDD-TURBT were higher compared to WL-TURBT, while there is the potential of PDD-TURBT to reduce the burden on healthcare economics in limited cases.

BACKGROUND: In the phase III open-label KEYNOTE-426 (NCT02853331) study, first-line pembrolizumab and axitinib improved overall survival (OS) and progression-free survival (PFS) versus sunitinib for metastatic renal cell carcinoma (mRCC). KEYNOTE-426 evaluated patients enrolled from 25 sites in Japan. METHODS: Patients enrolled in Japan were included in this post hoc subgroup analysis. Adults with clear cell mRCC were randomly assigned 1:1 to receive intravenous pembrolizumab 200 mg every 3 weeks plus oral axitinib 5 mg twice daily or oral sunitinib 50 mg once daily (4 weeks on/2 weeks off). Dual primary endpoints were OS and PFS as assessed by blinded independent central review. Objective response rate (ORR) and safety were secondary endpoints. RESULTS: The Japanese subgroup comprised 94 patients (pembrolizumab-axitinib, n = 44; sunitinib, n = 50; 11% of the intent-to-treat population). Median time from randomization to data cutoff (January 6, 2020) was 29.5 months (range 24.6-37.3). Consistent with the intent-to-treat population, the OS, PFS, and ORR suggested improvement with pembrolizumab-axitinib versus sunitinib in the Japanese subgroup. Grade ≥ 3 treatment-related adverse events (TRAEs) occurred in 70% of patients receiving pembrolizumab-axitinib versus 78% receiving sunitinib; 11 (25%) patients receiving pembrolizumab-axitinib and 13 (27%) patients receiving sunitinib discontinued the study medication due to AEs. TRAEs led to the discontinuation of pembrolizumab, axitinib, pembrolizumab-axitinib, or sunitinib in 32%, 34%, 14%, and 20%, respectively. No deaths from TRAEs occurred. CONCLUSIONS: Efficacy outcomes for the Japanese subgroup were consistent with those of the global population. Safety in Japanese patients was consistent with the results from the global population.

OBJECTIVE: Novel androgen receptor axis-targeted agents (ARATAs) have been developed for mCRPC and improved overall survival (OS). Here, we aimed to find predictors who will receive the greatest benefits from ARATAs. METHODS: We previously performed a multicenter study to identify prognostic factors for metastatic hormone-sensitive prostate cancer (mHSPC, n = 148) and mCRPC (n = 99), and showed that the bone scan index (BSI) was one of the significant prognostic factors for 3-year OS (PROSTAT-BSI study). mHSPC progressed to mCRPC (n = 101), for which 69 patients were treated with (n = 39) or without ARATAs (n = 30, prior to the approval of ARATAs). The 69 patients were divided into two groups according to patient factors, and these cohorts were further divided into two subgroups by usage of ARATAs. OS was compared between subgroups in each group. RESULTS: The predictors were age (<71.4 years), serum levels of C-reactive protein (≥0.16 ng/ml) and alkaline phosphatase (≥548 U/L), time to PSA progression after ADT (<8.9 months), the lowest PSA level (≥1 ng/ml) after ADT, and the rate of PSA decline 3 months after ADT (<0.987), whereas hemoglobin levels, PSA before ADT, Gleason scores, existence of visceral metastases, and BSI were not. CONCLUSIONS: The present study identified predictors for the effectiveness of ARATAs. The number of bone metastases (âBSI), existence of visceral metastases, and Gleason scores, which were identified as high-risk factors in the LATITUDE study and disease volume in CHAARTED criteria, did not appear to be useful for predicting effectiveness from ARATAs.

OBJECTIVES: Transurethral resection of bladder tumor with photodynamic diagnosis has been reported to result in lower residual tumor and intravesical recurrence rates in non-muscle invasive bladder cancer. We aimed to evaluate the usefulness of photodynamic diagnosis-transurethral resection of bladder tumor combined with oral 5-aminolevulinic acid hydrochloride for high-risk non-muscle invasive bladder cancer. METHODS: High-risk non-muscle invasive bladder cancer patients with an initial photodynamic diagnosis-transurethral resection of bladder tumor (photodynamic diagnosis group) were prospectively registered between 2018 to 2020. High-risk non-muscle invasive bladder cancer cases with a history of initial white-light transurethral resection of bladder tumor (white-light group) were retrospectively registered. Propensity score-matching analysis was used to compare residual tumor rates, and factors that could predict residual tumors at the first transurethral resection of bladder tumor were evaluated. RESULTS: Analyses were conducted with 177 and 306 cases in the photodynamic diagnosis and white-light groups, respectively. The residual tumor rates in the photodynamic diagnosis and white-light groups were 25.7% and 47.3%, respectively. Factor analysis for predicting residual tumors in the photodynamic diagnosis group showed that the residual tumor rate was significantly higher in cases with a current/past smoking history, multiple tumors, and pT1/pTis. When each factor was set as a risk level of 1, cases with a total risk score ≤1 showed a significantly lower residual tumor rate than cases with a total risk score ≥2 (8.3% vs 33.3%, odds ratio 5.46 [1.81-22.28]). CONCLUSIONS: In high-risk non-muscle invasive bladder cancer cases, the odds of a residual tumor after initial photodynamic diagnosis-transurethral resection of bladder tumor were 0.39-fold that of the odds of those after initial white-light transurethral resection of bladder tumor. A risk stratification model could be used to omit the second transurethral resection of bladder tumor in 27% of the cases.

INTRODUCTION: Our aim is to evaluate whether previous non-urothelial malignant history affects the clinical outcomes of patients with non-muscle invasive bladder cancer (NMIBC). PATIENTS AND METHODS: We identified 1097 cases treated by transurethral resection of bladder tumors for initially diagnosed NMIBC at our four institutions between 1999 and 2017. We compared clinical characteristics and outcomes between NMIBC patients with and without previous non-urothelial malignant history and investigated whether smoking status and treatment modality for previous cancer affected NMIBC outcomes. RESULTS: A total of 177 patients (16.1%) had previous non-urothelial malignant history (malignant history group). The 5-year recurrence-free survival rate and the 5-year progression-free survival rate in the malignant history group was 46.4% and 88.3%, respectively, which was significantly lower than that in the counterpart (60.2% p = 0.004, and 94.5% p = 0.002, respectively). A multivariate Cox regression analysis identified previous non-urothelial malignant history as an independent risk factor for tumor recurrence (p = 0.001) and stage progression (p = 0.003). In a subgroup of patients who were current smokers (N = 347), previous non-urothelial malignant history was associated with tumor recurrence and stage progression. In contrast, previous non-urothelial malignant history was not associated with tumor recurrence or stage progression in ex-smokers or non-smokers. In a subgroup analysis of NMIBC patients with previous prostate cancer history, those treated with androgen deprivation therapy had a significantly lower bladder tumor recurrence rate than their counterparts (p = 0.027). CONCLUSIONS: Previous history of non-urothelial malignancy may lead to worse clinical outcome in patients with NMIBC, particularly current smokers.

BACKGROUND: To investigate risk factors for orally administered 5-aminolevulinic acid (ALA)-induced hypotension for bladder cancer patients receiving photodynamic diagnosis (PDD)-assisted transurethral resection of bladder tumor (TURBT). METHODS: Patients were categorized into two groups intraoperatively: a hypotensive group (minimum systolic blood pressure (SBP) ≤80 mmHg) and a non-hypotensive group (minimum SBP > 80 mmHg). We examined differences between the hypotensive group and non-hypotensive groups to identify clinical risk of ALA-induced hypotension using multivariate logistic regression analysis and decision tree analysis. RESULTS: Among 282 cases with ALA-PDD-assisted TURBT from three institutions who were screened, 245 patients were included in the final analysis. In total, 156 patients (63.7%) showed any grade of hypotension during ALA-PDD-assisted TURBT. General anesthesia and spinal anesthesia were induced intraoperatively in 113 patients (46.1%) and 132 patients (53.9%), respectively. Median SBP at baseline (before taking ALA) and at the beginning of anesthesia was 127 mmHg (range, 69-186 mmHg) and 124 mmHg (range, 69-186 mmHg), respectively. Median minimum SBP during ALA-PDD-assisted TURBT was 75 mmHg (range, 43-140 mmHg). Multivariate logistic regression analysis revealed that history of hypertension (odds ratio (OR) 7.568, p < 0.05) and general anesthesia (OR 14.435, p < 0.05) as significantly associated with an increased risk of hypotension incidence. Use of calcium antagonist showed significant negative associations with hypotension (OR 0.183, p < 0.05). Decision tree analysis showed presence of general anesthesia, age ≥ 74 years and American Society of Anesthesiologists physical status (ASA-PS) ≥2 as the most important discriminators. CONCLUSIONS: General anesthesia and hypertension were independent risk factors related to ALA-induced hypotension. In contrast, use of calcium antagonists was identified as a factor associated with reduced risk of ALA-induced hypotension.

BACKGROUND: It currently remains unclear whether the location of primary tumours affects the clinical outcomes of patients with locally advanced urothelial carcinoma in the urinary tract. The aim of the present study was to compare prognostic differences between bladder urothelial carcinoma and upper tract urothelial carcinoma, particularly pT3 or higher tumours. METHODS: In total, 307 patients with pT3 or higher urothelial carcinoma without distant metastasis who underwent radical cystectomy for bladder urothelial carcinoma (N = 127, 41.4%) or radical nephroureterectomy for upper tract urothelial carcinoma (N = 180, 58.6%) at Keio University Hospital and three affiliated hospitals between 1994 and 2017 were enrolled. Oncological outcomes were compared between bladder urothelial carcinoma and upper tract urothelial carcinoma using Cox regression analysis. RESULTS: Significantly higher rates of male patients, smokers, neoadjuvant chemotherapy, lymph node involvement and lymphovascular invasion were observed in the bladder urothelial carcinoma group. The incidence of regional lymph node or local recurrence was higher in patients with bladder urothelial carcinoma than in those with upper tract urothelial carcinoma, while that of lung metastasis was lower. In all patients, bladder urothelial carcinoma was independently associated with disease recurrence (hazard ratio (HR) 1.504, P = 0.035) in addition to neoadjuvant chemotherapy and lymphovascular invasion. Bladder urothelial carcinoma was also independently associated with cancer death (HR = 1.998, P = 0.002) as well as lymphovascular invasion. Following the exclusion of patients who received neoadjuvant chemotherapy, bladder urothelial carcinoma remained an independent risk factor for disease recurrence and cancer death (HR = 1.702, P = 0.010 and HR = 1.888, P = 0.013, respectively). CONCLUSIONS: Bladder urothelial carcinoma may follow worse prognosis compared to upper tract urothelial carcinoma, particularly that with a high pathological stage.

BACKGROUND: Prophylactic urethrectomy at the time of radical cystectomy is frequently recommended for patients with bladder cancer at a high risk of urethral recurrence without definitive evidence. The present study attempted to clarify the survival benefits of performing prophylactic urethrectomy. METHODS: We identified 214 male patients who were treated by radical cystectomy with an incontinent urinary diversion in our seven institutions between 2004 and 2017. We used propensity score matching and ultimately identified 114 patients, 57 of whom underwent prophylactic urethrectomy (prophylactic urethrectomy group) and 57 who did not (non-prophylactic urethrectomy group). RESULTS: No significant differences were observed in the 5-year overall survival rate between the prophylactic urethrectomy and non-prophylactic urethrectomy groups in the overall. However, the local recurrence rate was significantly lower in the prophylactic urethrectomy group than in the non-prophylactic urethrectomy group (P = 0.015). In the subgroup of 58 patients with multiple tumours and/or concomitant carcinoma in situ at the time of transurethral resection of bladder tumour, the 5-year overall survival rate was significantly higher in the prophylactic urethrectomy group than in the non-prophylactic urethrectomy group (P = 0.021). A multivariate analysis revealed that performing prophylactic urethrectomy was the only independent predictor of the overall survival rate (P = 0.016). In those patients who were treated without neoadjuvant chemotherapy (n = 38), the 5-year overall survival rate was significantly higher in the prophylactic urethrectomy group than in the non-prophylactic urethrectomy group (P = 0.007). CONCLUSIONS: Prophylactic urethrectomy at the time of radical cystectomy may have a survival benefit in patients with multiple tumours and/or concomitant carcinoma in situ, particularly those who do not receive neoadjuvant chemotherapy.

BACKGROUND: The effects of the type of anesthesia (spinal (SA) vs. general (GA)) used for transurethral resection of bladder tumor (TURBT) on non-muscle invasive bladder cancer (NMIBC) recurrence and progression are controversial and our aim is to investigate their associations. METHODS: We identified 300 NMIBC patients who underwent initial TURBT with SA or GA. Cox's regression analysis was performed to examine the effects of anesthesia on tumor recurrence. RESULTS: Among 300 patients, 153 (51.0%) received GA and 147 (49.0%) SA. The 5-year recurrence-free survival (RFS) rate was 59.9% in the GA group, which was significantly lower than that in the SA group (74.4%, p = 0.029). GA (HR 1.57, p = 0.048), male sex (HR 2.72, p = 0.012), and tumor multiplicity (HR 1.96, p = 0.006) were independently associated with tumor recurrence. In a subgroup of 137 patients with high-risk NMIBC, the 5-year RFS rate was 50.3% in the GA group, which was significantly lower than that in the SA group (77.6%, p = 0.020), and GA remained an independent indicator of tumor recurrence (HR 2.35, p = 0.016). However, no significant differences were observed in the RFS rates of low- to intermediate-risk NMIBC patients between the GA and SA groups. CONCLUSIONS: The RFS rate was lower in NMIBC patients who received GA during TURBT than in those who received SA. Volatile anesthesia may increase tumor recurrence, particularly in high-risk NMIBC patients, which may be due to the inhibition of the immune response system during surgery.

OBJECTIVE: The aim of this study was to evaluate the clinical significance of the on-treatment C-reactive protein (CRP) status during systemic treatment as the predictive marker for the response of subsequent nivolumab monotherapy in patients with refractory metastatic renal cell carcinoma (mRCC). PATIENTS AND METHODS: A total of 73 mRCC patients treated with nivolumab were retrospectively reviewed. We evaluated the serum CRP levels before and after molecular-targeted treatments. Patients whose CRP did not exceed baseline value were defined as the CRP-control group and the others were defined as the CRP-progression group. The clinical impact of CRP-control on the efficacy of nivolumab was assessed. RESULTS: Twenty-four patients (33%) were categorized into the CRP-control group. The CRP-control group patients (median PFS not reached) had significantly longer PFS than the CRP-progression group (median PFS 11.9 months, 95% confidence interval, CI 4.1-19.8, p = 0.038). The CRP-control group had a tendency of longer OS from nivolumab initiation than the CRP-progression group (p = 0.071). By multivariate analysis, the on-treatment CRP-control was the independent predictive factor for PFS (hazard ratio HR 0.37, 95% CI 0.14-0.99, p = 0.047). CONCLUSION: The on-treatment CRP-control could be the predictive factor for the efficacy of nivolumab in refractory mRCC patients.
RESUMEN
PURPOSE: The goal of the present study was to determine factors related to a ceiling effect (CE) on the EQ-5D-5L among Japanese patients with prostate cancer (PC). METHODS: An existent cross-sectional observational study dataset was used. Patients were ≥ 20 years of age and diagnosed with PC. For CE determinants on the EQ-5D-5L, we excluded possible "full-health" patients flagged by the EQ-VAS (score = 100) and/or FACT-P (score = 156) instruments. We then divided them into binary variables: A CE group (EQ-5D-5L score = 1) and others (< 1). The associations between CE, sociodemographic and medical characteristics, and FACT-P subscale scores were examined using a multivariate LASSO selection followed by a binomial logistic regression analysis performed to calculate odds ratios (ORs) and 95% confidence intervals (CIs). RESULTS: A total of 362 patients were analyzed. The LASSO selection variables, including all obtained variables, were as follows: age, palliative treatment, FACT-P physical well-being, and PC subscale score. Statistically significant variables predicting CE were palliative treatment (OR 0.23; 95% CI 0.09-0.60), physical well-being (OR 1.54; 95% CI 1.34-1.76), and PC subscale (OR 1.08; 95% CI 1.03-1.14). CONCLUSIONS: This study revealed that palliative treatment and two FACT-P physical well-being and PC subscale scores were positively related to CE on the EQ-5D-5L. To our knowledge, this is the first study to examine predictors of CE on the EQ-5D-5L. The present results may be helpful for facilitating the consideration of "bolt-on" studies from the standpoint of PC patients.

BACKGROUND: Nivolumab has become an effective treatment option for cancer in various sites; however, this drug may cause immune-related adverse effects due to its mechanism of action. Furthermore, little has been reported on thiamine deficiency (TD) in patients receiving nivolumab treatment. METHOD: From a series of cancer patients, we reported a patient with recurrent renal cell carcinoma who developed TD after the start of nivolumab treatment. RESULTS: A 74-year-old man with recurrent renal cell carcinoma was referred to the psycho-oncology department as he had lost about 4 kg and displayed a loss of energy after four cycles of nivolumab treatment. Psychiatric interviews revealed a decrease in energy. Neurological examination did not reveal any impairment in consciousness, ataxia, or ocular symptoms. He did not develop appetite loss. The malabsorption or overconsumption of some nutrients is thought to occur due to the rapid loss of weight; thus, a reduction in vitamin B1, which has a short storage period in the body and is often deficient in cancer patients, was suspected. The diagnosis of TD was supported by the patient's abnormally low serum thiamine level. SIGNIFICANCE OF RESULTS: In patients treated with nivolumab, it is necessary to pay careful attention to TD when proceeding with the treatment. It is hoped that future research may reveal the link between nivolumab administration and TD.
