Despite currently used intravesical therapies in non-muscle-invasive bladder cancer (NMIBC), the rate of intravesical recurrence remains very high. We aimed to evaluate the effectiveness of adding nonintravesical interventions to standard intravesical therapies to prevent intravesical recurrence. In April 2024, 3 databases were queried for prospective studies evaluating nonintravesical interventions in addition to standard intravesical therapies for NMIBC (CRD42024490988). The primary outcome was intravesical recurrence-free survival (iRFS). Standard pairwise meta-analyses were performed using hazard ratios (HR) and 95% confidence intervals (95% CI) with a random-effects model. We identified 18 eligible studies (14 RCTs and 4 prospective trials) comprising 4,593 NMIBC patients, which investigated pharmacological interventions (eg, selenium, vitamins, Lactobacillus casei, celecoxib, metformin, mistletoe lectin) and lifestyle modifications (diet). The addition of Lactobacillus casei significantly improved iRFS (HR: 0.50; 95% CI: 0.34-0.73; P < .001). A high western diet pattern significantly worsened iRFS (HR:1.48, 95%CI:1.06-2.06, P = .03). The other nonintravesical interventions were not associated with iRFS. Our comprehensive review of the published literature highlights the need for further research into the efficacy of nonvesical interventions for NMIBC. While Lactobacillus was shown to improve iRFS in 2 RCTs, additional high-quality randomized studies are required to evaluate the effectiveness of other interventions.

Recent phase 3 randomized controlled trials (RCTs) demonstrate the promising impact of immune checkpoint inhibitor (ICI)-based combination therapies on locally advanced or metastatic urothelial carcinoma (UC). However, comparative data on the efficacy and toxicity of different ICI-based combinations are lacking. This study aims to compare the efficacy of first-line ICI-based combination therapies for locally advanced or metastatic UC using phase 3 RCT data. In November 2023, three databases were searched for RCTs evaluating oncological outcomes in patients with locally advanced or metastatic UC who were treated with first-line ICI-based combination therapies. Network meta-analysis (NMA) was conducted to compare outcomes, including overall survival (OS), progression-free survival (PFS), objective response rates (ORRs), complete response rates (CRRs), and treatment-related adverse events (TRAEs). Subgroup analyses were based on PD-L1 status and cisplatin eligibility. The NMA included five RCTs. Enfortumab vedotin (EV) + pembrolizumab ranked the highest for improving OS (100%), PFS (100%), ORR (96%), and CRR (96%), followed by nivolumab + chemotherapy. EV + pembrolizumab combination superiority held across PD-L1 status and cisplatin eligibility. In patients who are cisplatin-eligible, EV + pembrolizumab significantly improved OS (HR: 0.68, 95%CI 0.47-0.99) and PFS (HR: 0.67, 95%CI 0.49-0.92) compared to nivolumab + chemotherapy. Durvalumab + tremelimumab was the safest combination for severe TRAEs, and EV + pembrolizumab ranked second. Our analyses support EV + pembrolizumab combination as a first-line treatment for locally advanced or metastatic UC. Thus, EV + pembrolizumab may become a guideline-changing standard treatment.

CONTEXT: Adjuvant immune checkpoint inhibitors (ICIs) have recently emerged as guideline-recommended treatments of high-risk muscle-invasive urothelial carcinoma (MIUC). However, there is limited evidence regarding the optimal candidates and the differential efficacy of adjuvant ICI regimens. OBJECTIVE: To synthesize and compare the efficacy and safety of adjuvant ICIs for high-risk MIUC using updated data from phase III randomized controlled trials. EVIDENCE ACQUISITION: In April 2024, three databases were searched for eligible randomized controlled trials that evaluated oncologic outcomes in patients with MIUC treated with adjuvant ICIs. Pairwise meta-analysis (MA) and network meta-analyses were performed to compare the hazard ratios of oncological outcomes, including disease-free survival (DFS), overall survival (OS), and adverse events. Subgroup analyses were conducted on the basis of predefined clinicopathological features. EVIDENCE SYNTHESIS: Three randomized controlled trials that assessed the efficacy of adjuvant nivolumab, pembrolizumab, and atezolizumab were included in the MAs and network meta-analyses groups. Pairwise MAs showed that treatment with adjuvant ICIs significantly improved DFS [hazards ratio: 0.77, 95% confidence interval (CI): 0.66-0.90] as well as OS (hazards ratio: 0.87, 95% CI 0.76-1.00) in patients with MIUC compared with in the placebo/observation group. The DFS benefit was prominent in patients who underwent neoadjuvant chemotherapy (P = 0.041) and in those with bladder cancer (P = 0.013) but did not differ across programmed death-ligand 1 and lymph node status. Adjuvant ICI therapy was associated with increased risk of any (OR: 2.98, 95% CI 2.06-4.33) and severe adverse events (OR: 1.78, 95% CI 1.49-2.13). The treatment rankings revealed that pembrolizumab for DFS (84%) and nivolumab for OS (93%) had the highest likelihood of improving survival. CONCLUSIONS: Our analyses demonstrated the DFS and OS benefits of adjuvant ICIs for high-risk MIUC. Furthermore, patients with bladder cancer who underwent neoadjuvant chemotherapy appeared to be the optimal candidates for adjuvant ICIs regarding prolonged DFS. Adjuvant ICIs are the standard of care for high-risk MIUC, and differential clinical behaviors and efficacy will enrich clinical decision-making.

OBJECTIVE: To examine whether antimicrobial prophylaxis based on screening rectal cultures using selective media prevented acute bacterial prostatitis following transrectal prostate biopsy (TRPB). METHODS: In this multicenter, randomized controlled trial, we enrolled 403 patients undergoing TRPB with low risks of infectious complications. Patients were randomized into a cultured group (CG) or no cultured group (NCG). In the CG, patients with positive culture results for fluoroquinolone (FQ)-resistant or extended-spectrum β-lactamase (ESBL)-producing Escherichia coli (E. coli) used piperacillin/tazobactam as prophylaxis, and those with negative culture results and in the NCG used levofloxacin. The primary endpoint was the incidence of acute prostatitis after TRPB. The secondary endpoint was the accuracy of the selective media. RESULTS: Of 373 patients (CG, 187; NCG, 186), 67 were positive, and 120 were negative for rectal culture in the CG. The overall incidence of prostatitis after TRPB was 1.1% (n=4). The incidences in the CG and the NCG were 1.6% (n=3, all negative-culture cases) and 0.5% (n=1), respectively, without significant difference (P=0.3). No prostatitis occurred in the positive-culture group. The sensitivity and specificity of the levofloxacin-insusceptible selective media were 98.1% and 94.7%, respectively. CONCLUSION: Screening with selective media before TRPB in patients with low infectious risks may provide additive value to preventing post-biopsy prostatitis. Piperacillin/tazobactam can be considered when FQ-resistant or ESBL-producing E. coli is detected.

OBJECTIVES: This study aimed to compare the clinical outcomes of robot-assisted partial nephrectomy (RAPN) and image-guided percutaneous cryoablation (IG-PCA) for clinical T1 renal cell carcinoma. MATERIALS AND METHODS: We conducted a retrospective analysis of 679 patients with clinical T1 renal cell carcinoma treated with RAPN or IG-PCA between 2012 and 2021. Propensity scores were calculated via logistic analysis to adjust for imbalances in baseline characteristics. We compared oncological and functional outcomes between the 2 treatment groups. RESULTS: Following the matching process, 108 patients were included in each group. No patient in the RAPN group developed local recurrence. In the IG-PCA group, three patients experienced local tumor progression. The patients underwent salvage thermal ablations by the secondary technique; 2 underwent IG-PCA and 1 underwent microwave ablation, resulting in a local control rate of 100%. The Kaplan-Meier analysis showed no statistically significant differences between the groups in terms of 5-year recurrence-free survival, metastasis-free survival, and overall survival (log-rank test; P = 0.11, P = 0.64, and P = 0.17, respectively). No significant differences were observed in the 2 treatments in major and overall complication rates (P = 0.75 and P = 0.82, respectively). Both groups showed similar rates of less than 10% estimated glomerular filtration rate decline at 12 months post-treatment and 5-year renal function preservation rates (P = 0.88 and P = 0.38, respectively). CONCLUSIONS: IG-PCA demonstrated oncological outcomes comparable to those of RAPN. RAPN addressed the disadvantages of conventional procedures and allowed for safety outcomes comparable to IG-PCA.

Although partial nephrectomy (PN) is preferred over radical nephrectomy (RN) for preserving renal function in patients with cT1 renal cancer, its impact on cardiovascular events (CVe) remains controversial. This study aimed to compare PN and RN in regard to the occurrence of CVe, including cerebrovascular events and exacerbation of hypertension (HT). We retrospectively analyzed 418 consecutive patients who underwent PN or RN for cT1 renal cancer. Propensity score-matching analysis was used to adjust for imbalances between patients who underwent PN and RN, leaving 102 patients in each group. The 5-year probability of cumulative CVe incidence was 6% in the PN group and 12% in the RN group (p=0.03), with a median follow-up of 73.5 months. The statistical significance was retained after propensity score matching for patients without preoperative proteinuria (p=0.03). For all CVe including cerebrovascular events and exacerbation of HT analyzed, PN provided a lower probability of occurrence than RN in patients with small renal cancers.

Although immune checkpoint inhibitors (ICI) and/or tyrosine kinase inhibitors (TKI) are the standard treatment of advanced unresectable or metastatic renal cell carcinoma (RCC), the impact of concomitant medications remains unclear. We aimed to evaluate the impact of concomitant medications on survival outcomes in patients treated with systemic therapy for advanced unresectable or metastatic RCC. In August 2024, PubMed, Scopus, and Web of Science were queried for studies evaluating concomitant medications in patients with advanced unresectable or metastatic RCC (PROSPERO: CRD42024573252). The primary outcome was overall survival (OS). A fixed- or random-effects model was used for meta-analysis according to heterogeneity. We identified 22 eligible studies (5 prospective and 17 retrospective) comprising 16,072 patients. Concomitant medications included proton pump inhibitors (PPI) (n = 3959), antibiotics (n = 571), statins (n = 5466), renin-angiotensin system inhibitors (RASi) (n = 6615), and beta-blockers (n = 1964). Both concomitant PPI and antibiotics were significantly associated with worse OS in patients treated with ICI (PPI: HR: 1.22, P = .01, and antibiotics: HR: 2.09, P < .001). Concomitant statins, RASi, or beta-blocker were significantly associated with improved OS in patients treated with TKI (statins: HR: 0.81, P = .03, RASi: HR: 0.63, P < .001, beta-blocker: HR: 0.69, P < .001, respectively). In patients treated with ICI, RASi was significantly associated with improved OS (HR: 0.64, P = .02). Concomitant use of antibiotics or PPI with ICI can reduce its oncologic efficacy. Conversely, concomitant statins, RASi, or beta-blockers can enhance the oncologic efficacy of TKI. When initiating systemic therapy for metastatic RCC, it may be important for clinicians to assess baseline co-medications and recognize their possible positive or negative effects.

BACKGROUND AND OBJECTIVE: While active surveillance (AS) is an alternative to surgical interventions in patients with small renal masses (SRMs), evidence regarding its oncological efficacy is still debated. We aimed to evaluate oncological outcomes for patients with SRMs who underwent AS in comparison to surgical interventions. METHODS: In April 2024, PubMed, Scopus, and Web of Science were queried for comparative studies evaluating AS in patients with SRMs (PROSPERO: CRD42024530299). The primary outcomes were overall (OS) and cancer-specific survival (CSS). A random-effects model was used for quantitative analysis. KEY FINDINGS AND LIMITATIONS: We identified eight eligible studies (three prospective, four retrospective, and one study based on Surveillance, Epidemiology and End Results [SEER] data) involving 4947 patients. Pooling of data with the SEER data set revealed significantly higher OS rates for patients receiving surgical interventions (hazard ratio [HR] 0.73; p = 0.007), especially partial nephrectomy (PN; HR 0.62; p < 0.001). However, in a sensitivity analysis excluding the SEER data set there was no significant difference in OS between AS and surgical interventions overall (HR 0.84; p = 0.3), but the PN subgroup had longer OS than the AS group (HR 0.6; p = 0.002). Only the study based on the SEER data set showed a significant difference in CSS. The main limitations include selection bias in retrospective studies, and classification of interventions in the SEER database study. CONCLUSIONS AND CLINICAL IMPLICATIONS: Patients treated with AS had similar OS to those who underwent surgery or ablation, although caution is needed in interpreting the data owing to the potential for selection bias and variability in AS protocols. Our review reinforces the need for personalized shared decision-making to identify patients with SRMs who are most likely to benefit from AS. PATIENT SUMMARY: For well-selected patients with a small kidney mass suspicious for cancer, active surveillance seems to be a safe alternative to surgery, with similar overall survival. However, the evidence is still limited and more studies are needed to help in identifying the best candidates for active surveillance.

OBJECTIVES: The advancement of laparoscopic surgery has allowed surgeons to see finer anatomical structures during surgery. As a result, several issues have arisen regarding Gerota fascia that cannot be explained by previous interpretations, such as its various forms observed during surgery. To address these issues, we histologically examined the structure of Gerota fascia. METHODS: Specimens for study were prepared from kidneys with Gerota fascia from four cadavers, and the structure was studied histologically. Its thickness and collagen fiber area ratios were measured using ImageJ and compared to those of the epimysium of the rectus abdominis muscle. RESULTS: Connective tissue that appeared to be Gerota fascia was observed in 26 specimens. Histologically, the basic structure of Gerota fascia was a sandwich-like structure with a thin layer of thick, long collagen fibers in the central layer, and small granular collagen fibers scattered at the edges. However, not all areas observed had a similar structure; eight specimens were composed only of small granular collagen fibers. The average thickness of the Gerota fascia was 466 μm, and the area ratio of collagen was 27.1%. In contrast, the epimysium was much thicker than Gerota fascia, and its collagen fibers were much thicker and denser. CONCLUSIONS: Gerota fascia, unlike the epimysium, was a very thin and fragile layer of collagen fibers, and its structure was diverse. This explains why Gerota fascia was observed in various states during surgery. It is important for surgeons to understand the properties of Gerota fascia and to treat it appropriately.

Adrenocortical carcinoma (ACC) is a rare and aggressive malignancy with a high recurrence rate after surgical therapy with curative intent. Adjuvant radiotherapy (RT) and mitotane therapy have been proposed as options following the adrenalectomy. However, the efficacy of adjuvant RT or mitotane therapy remains controversial. We aimed to evaluate the efficacy of adjuvant therapy in patients who underwent adrenalectomy for localised ACC. The PubMed, Scopus, and Web of Science databases were queried on March 2024 for studies evaluating adjuvant therapies in patients treated with surgery for localized ACC (PROSPERO: CRD42024512849). The endpoints of interest were overall survival (OS) and recurrence-free survival (RFS). Hazard ratios (HR) with 95% confidence intervals (95%CI) were pooled in a random-effects model meta-analysis. One randomized controlled trial (n = 91) and eleven retrospective studies (n = 4,515) were included. Adjuvant mitotane therapy was associated with improved RFS (HR: 0.63, 95%CI: 0.44-0.92, p = 0.016), while adjuvant RT did not reach conventional levels of statistical significance (HR:0.79, 95%CI:0.58-1.06, p = 0.11). Conversely, Adjuvant RT was associated with improved OS (HR:0.69, 95%CI:0.58-0.83, p<0.001), whereas adjuvant mitotane did not (HR: 0.76, 95%CI: 0.57-1.02, p = 0.07). In the subgroup analyses, adjuvant mitotane was associated with better OS (HR:0.46, 95%CI: 0.30-0.69, p < 0.001) and RFS (HR:0.56, 95%CI: 0.32-0.98, p = 0.04) in patients with negative surgical margin. Both adjuvant RT and mitotane were found to be associated with improved oncologic outcomes in patients treated with adrenalectomy for localised ACC. While adjuvant RT significantly improved OS in general population, mitotane appears as an especially promising treatment option in patients with negative surgical margin. These data can support the shared decision-making process, better understanding of the risks, benefits, and effectiveness of these therapies is still needed to guide tailored management of each individual patient.

BACKGROUND: Although previous literature shows tumor location as a prognostic factor in upper tract urothelial carcinoma (UTUC), there remains uninvestigated regarding the impact of tumor location on grade concordance and discrepancies between ureteroscopic (URS) biopsy and final radical nephroureterectomy(RNU) pathology. METHODS: In this international study, we retrospectively reviewed the records of 1,498 patients with UTUC who underwent diagnostic URS with concomitant biopsy followed by RNU between 2005 and 2020. Tumor location was divided into four sections: the calyceal-pelvic system, proximal ureter, middle ureter, and distal ureter. Patients with multifocal tumors were excluded from the study. We performed multiple comparison tests and logistic regression analyses. RESULTS: Overall, 1,154 patients were included; 54.4% of those with low-grade URS biopsies were upgraded on RNU. In the multiple comparison tests, middle ureter tumors exhibited the highest probability of upgrading, meanwhile pelvicalyceal tumors exhibited the lowest probability of upgrading (73.7% vs 48.5%, p=0.007). Downgrading was comparable across all tumor locations. On multivariable analyses, middle ureteral location was significantly associated with a low probability of grade concordance (OR 0.59; 95%CI, 0.35-1.00; p =0.049) and an increased risk of upgrading (OR 2.80; 95%CI, 1.20-6.52; p =0.017). The discordance did not vary regardless of caliceal location, including the lower calyx. CONCLUSIONS: Middle ureteral tumors diagnosed to be low-grade had a high probability to be undergraded. Our data can inform providers and their patients regarding the likelihood of undergrading according to tumor location, facilitating patient counselling and shared decision making regarding the choice of kidney sparing vs RNU.

OBJECTIVE: To investigate the influence of statins on the survival outcomes of patients with non-muscle-invasive bladder cancer (NMIBC) treated with adjuvant intravesical bacille Calmette-Guérin (BCG) immunotherapy. PATIENTS AND METHODS: A retrospective cohort of consecutive patients with NMIBC who received intravesical BCG therapy from 2001 to 2020 and statins prescription were identified. Overall survival (OS), cancer-specific survival (CSS), recurrence-free survival (RFS), and progression-free survival (PFS) were analysed between the Statins Group vs No-Statins Group using Kaplan-Meier method and multivariable Cox regression. RESULTS: A total of 2602 patients with NMIBC who received intravesical BCG were identified. The median follow-up was 11.0 years. On Kaplan-Meier analysis, the Statins Group had significant better OS (P < 0.001), CSS (P < 0.001), and PFS (P < 0.001). Subgroup analysis indicated statins treatment started before BCG treatment had better CSS (P = 0.02) and PFS (P < 0.01). Upon multivariable Cox regression analysis, the 'statins before BCG' group was an independent protective factor for OS (hazard ratio [HR] 0.607, 95% confidence interval [CI] 0.514-0.716), and CSS (HR 0.571, 95% CI 0.376-0.868), but not RFS (HR 0.885, 95% CI 0.736-1.065), and PFS (HR 0.689, 95% CI 0.469-1.013). CONCLUSIONS: Statins treatment appears to offer protective effects on OS and CSS for patients with NMIBC receiving adjuvant intravesical BCG.

BACKGROUND: Metastatic nonclear cell renal cell carcinoma (nccRCC) is a heterogeneous disease with poor prognosis. The clinical characteristics and prognostic factors of immuno-oncology (IO) combination therapy for nccRCC are not well known. This study analyzed patients with metastatic nccRCC treated with IO combination therapy. METHODS: We retrospectively collected data from 447 patients with metastatic RCC treated with IO-based combination therapy as first-line treatment between September 2018 and July 2023 in a Japanese multicenter study. The primary endpoints were objective response rate, progression-free survival (PFS), and overall survival (OS), comparing groups treated with IO-IO and IO-tyrosine kinase inhibitor (TKI) therapies. RESULTS: Seventy-five patients with metastatic nccRCC were eligible for analysis: 39 were classified into the IO-IO group and 36 into the IO-TKI group. Median PFS was 5.4 months (95% CI: 1.6-9.1) for the IO-IO group and 5.6 (95% CI: 3.4-12.0) for the IO + TKI group. Median OS was 24.2 months (95% CI: 7.5-NA) for the IO-IO group and 23.4 (95% CI: 18.8-NA) for the IO + TKI group, with no significant difference. In univariate analysis, International Metastatic Renal Cell Carcinoma Database Consortium scores, Karnofsky performance status, neutrophil-to-lymphocyte ratio, and the presence of liver metastases were significantly associated with OS, whereas in multivariate analysis, only the presence of liver metastases was significantly associated with OS (P = .035). CONCLUSIONS: There was no significant difference in OS or PFS between IO-IO and IO-TKI combination therapy as first-line treatment for patients with nccRCC. Liver metastasis is a poor prognostic factor for such patients.

CONTEXT: Radical nephroureterectomy (RNU) with bladder cuff resection is the standard treatment in patients with high-risk upper tract urothelial cancer (UTUC). However, it is unclear which specific surgical technique may lead to improve oncological outcomes in term of intravesical recurrence (IVR) in patients with UTUC. OBJECTIVE: To evaluate the efficacy of surgical techniques and approaches of RNU in reducing IVR in UTUC patients. EVIDENCE ACQUISITION: Three databases were queried in January 2024 for studies analyzing UTUC patients who underwent RNU. The primary outcome of interest was the rate of IVR among various types of surgical techniques and approaches of RNU. EVIDENCE SYNTHESIS: Thirty-one studies, comprising 1 randomized controlled trial and 1 prospective study, were included for a systematic review and meta-analysis. The rate of IVR was significantly lower in RNU patients who had an early ligation (EL) of the ureter compared to those who did not (HR: 0.64, 95% CI: 0.44-0.94, p = 0.02). Laparoscopic RNU significantly increased the IVR compared to open RNU (HR: 1.28, 95% CI: 1.06-1.54, p < 0.001). Intravesical bladder cuff removal significantly reduced the IVR compared to both extravesical and transurethral bladder cuff removal (HR: 0.65, 95% CI: 0.51-0.83, p = 0.02 and HR: 1.64, 95% CI: 1.15-2.34, p = 0.006, respectively). CONCLUSIONS: EL of the affected upper tract system, ureteral management, open RNU, and intravesical bladder cuff removal seem to yield the lowest IVR rate in patients with UTUC. Well-designed prospective studies are needed to conclusively elucidate the optimal surgical technique in the setting of single post-operative intravesical chemotherapy.

PURPOSE: Immune checkpoint inhibitor (ICI)-based combination therapy is a standard systemic treatment for metastatic renal cell carcinoma (mRCC). Although differential pharmacologic action between ICI+ICI and ICI+tyrosine kinase inhibitor (TKI) combinations may affect outcomes, comparative studies using real-world data are few. METHODS: We retrospectively analyzed the records of 447 mRCC patients treated with 1st-line ICI-based combinations at multiple institutions between January 2018 and August 2023, and selected 320 patients diagnosed with clear cell RCC (ccRCC) for further study. Cohorts were matched using one-to-one propensity scores based on IMDC risk classification. Overall survival (OS), progression-free survival (PFS), objective response rates (ORRs), and treatment-related adverse events (TrAE) were compared. RESULTS: The matching process yielded 228 metastatic ccRCC patients treated with ICI+ICI (n = 114) or ICI+TKI (n = 114). Median OS was 53 months (95%CI: 33-NA) in patients treated with ICI+ICI and was not reached (95%CI: 43-NA) with ICI+TKI (P = 0.24). Median PFS was significantly shorter for ICI+ICI (13 months, 95%CI: 7-25) than for ICI+TKI (25 months, 95%CI: 13-NA) (P = 0.047). There were no differences in second-line PFS for sequential therapy after 1st-line combinations of ICI+ICI or ICI+TKI (6 vs. 8 months, P = 0.6). There were no differences in ORR between the 2 groups (ICI+ICI: 51% vs. ICI+TKI: 55%, P = 0.8); the progressive disease (PD) rate was significantly higher in patients treated with the ICI+ICI combination (24% vs. 11%, P = 0.029). The rate of any grade TrAE was significantly higher in patients treated with ICI+TKI (71% vs. 85%, P = 0.016), but we found no differences in severe TrAE between the 2 groups (39% vs. 36%, P = 0.8). CONCLUSIONS: In a matched cohort of real-world data, we confirmed comparable OS benefits between ICI+ICI and ICI+TKI combinations. However, differential clinical behaviors in terms of PFS, PD rates, and TrAE between ICI-based combinations may enrich clinical decision-making.
