Adjuvant immune checkpoint inhibitor therapies have radically altered the treatment landscape for renal cell carcinoma and urothelial carcinoma. However, studies have reported negative data regarding adjuvant immune checkpoint inhibitor therapies. Thus, this study aimed to assess the role of adjuvant immune checkpoint inhibitor therapy for both renal cell carcinoma and urothelial carcinoma. A systematic review and network meta-analysis were conducted in compliance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses statement. Multiple databases were searched for articles published as of February 2023. Studies were deemed eligible if they evaluated disease-free survival in patients with renal cell carcinoma and urothelial carcinoma receiving adjuvant immune checkpoint inhibitor therapy. Five studies met the inclusion criteria. In a network meta-analysis, pembrolizumab was shown to be the most effective regimen for patients with renal cell carcinoma, whereas nivolumab was found to be the most effective regimen for patients with urothelial carcinoma. Additionally, these results were consistently observed in a sub-analysis of the T stage. The present analysis provides findings that support the usefulness of adjuvant nivolumab therapy in urothelial carcinoma and adjuvant pembrolizumab therapy in renal cell carcinoma, in agreement with the currently available guidelines. However, the caveat is that the randomized controlled trials included in this analysis differed in important respects despite being similar in study design. Therefore, with these differences in mind, care needs to be taken when selecting patients for these immune checkpoint inhibitor therapies to maximize their benefits.

Immune checkpoint inhibitor (ICI)-based combination therapies are the recommended first-line treatment for metastatic renal cell carcinoma (mRCC). However, no head-to-head phase-3 randomized controlled trials (RCTs) have compared the efficacy of different ICI-based combination therapies. Here, we compared the efficacy of various first-line ICI-based combination therapies in patients with mRCC using updated survival data from phase-3 RCTs. Three databases were searched in June 2023 for RCTs that analyzed oncologic outcomes in mRCC patients treated with ICI-based combination therapies as first-line treatment. A network meta-analysis compared outcomes including overall survival (OS), progression-free survival (PFS), objective response rate (ORR), and complete response (CR) rate. Subgroup analyses were based on the International mRCC Database Consortium risk classification. The treatment ranking analysis of the entire cohort showed that nivolumab + cabozantinib (81%) had the highest likelihood of improving OS, followed by nivolumab + ipilimumab (75%); pembrolizumab + lenvatinib had the highest likelihood of improving PFS (99%), ORR (97%), and CR (86%). These results remained valid even when the analysis was limited to patients with intermediate/poor risk, except that nivolumab + ipilimumab had the highest likelihood of achieving CR (100%). Further, OS benefits of ICI doublets were not inferior to those of ICI + tyrosine kinase inhibitor combinations. Recommendation of combination therapies with ICIs and/or tyrosine kinase inhibitors based on survival benefits and patient pretreatment risk classification will help advance personalized medicine for mRCC.

PURPOSE: Detrusor muscle (DM) in the resected specimen of patients with pT1 bladder cancer (BCa) is a quality-of-care criteria. We aimed to assess whether obtaining adequate DM is dependent on surgeon's experience, whether is a surrogate for resection quality, and whether the degree of DM thickness is related to postoperative outcomes in en bloc resection for bladder tumors (ERBT). MATERIALS AND METHODS: We retrospectively analyzed the records of 106 pT1 high-grade BCa patients who underwent ERBT at several institutions. All specimens were reviewed by a single pathologist who assessed the presence or absence of DM and its thickness measured by a micrometer, when present. Early recurrence, defined as pathologically confirmed BCa on repeat resection or tumor recurrence at the first follow-up cystoscopy (within 3 months), was the endpoint reflective of the resection quality. RESULTS: Of 106 patients, DM was detected in 99 (93%), and the median DM thickness was 1.8 mm. Large tumor size (>30 mm) was associated with adequate DM sampling (>1.8mm) (odds ratio [OR]: 6.10, 95% confidence intervals [CIs]: 2.08-17.9, P = 0.001), while surgeon's experience was not. DM presence and DM thickness were both not associated with early recurrence, while positive surgical margin was an independent prognosticator for early recurrence (OR: 3.38, 95% CI: 1.12-10.2, P = 0.031). Excessive DM sampling (>2.1 mm) was associated with prolonged urethral catheterization (OR: 28.8, 95% CI: 3.36-248, P = 0.002). CONCLUSIONS: In ERBT, surgeon's experience seems irrelevant to obtain DM. Resection quality relies on surgical margin status, not the degree of DM. Obtaining excessive DM incurs adverse events/unnecessary medical care.

PURPOSE: The aim of this study was to investigate the oncologic efficacy of combining docetaxel with androgen deprivation therapy (ADT) versus nonsteroidal antiandrogen (NSAA) with ADT in patients with high-volume metastatic hormone-sensitive prostate cancer (mHSPC) with focus on the effect of sequential therapy in a real-world clinical practice setting. METHODS: The records of 382 patients who harbored high-volume mHSPC, based on the CHAARTED criteria, and had received ADT with either docetaxel (n = 92) or NSAA (bicalutamide) (n = 290) were retrospectively analyzed. The cohorts were matched by one-to-one propensity scores based on patient demographics. Overall survival (OS), cancer-specific survival (CSS), progression-free survival (PFS), including time to castration-resistant prostate cancer (CRPC), and time to second-line progression (PFS2) were compared. 2nd-line PFS defined as the time from CRPC diagnosis to progression after second-line therapy was also compared. RESULTS: After matching, a total of 170 patients were retained: 85 patients treated with docetaxel + ADT and 85 patients treated with NSAA + ADT. The median OS and CSS for docetaxel + ADT versus NSAA + ADT were not reached (NR) vs. 49 months (p = 0.02) and NR vs. 55 months (p = 0.02), respectively. Median time to CRPC and PFS2 in patients treated with docetaxel + ADT was significantly longer compared to those treated with NSAA (22 vs. 12 months; p = 0.003 and, NR vs. 28 months; p < 0.001, respectively). There was no significant difference in 2nd-line PFS between the two groups. CONCLUSIONS: Our analysis suggested that ADT with docetaxel significantly prolonged OS and CSS owing to a better time to CRPC and PFS2 in comparison to NSAA + ADT in high-volume mHSPC.

OBJECTIVES: To assess the clinical significance of repeat transurethral resection (reTUR) and surgical margin status after en bloc resection of bladder tumour (ERBT) for pathological T1 (pT1) bladder cancer. PATIENTS AND METHODS: We retrospectively analysed the record of 106 patients with pT1 high-grade bladder cancer who underwent ERBT between April 2013 and February 2021 at multiple institutions. All specimens were reviewed by a genitourinary pathologist. The primary outcome measures were recurrence-free survival (RFS) and progression-free survival (PFS) between patients with and those without reTUR. We also analysed the predictive value of surgical margin on the likelihood of residual tumour on reTUR. RESULTS: A reTUR was performed in 50 of the 106 patients. The 2-year RFS and 3-year PFS were comparable between patients who underwent reTUR and those who did not (55.1% vs 59.9%, P = 0.6, 80.6% vs 82.6%, P = 0.6, respectively). No patient was upstaged to pT2 on reTUR. Regarding the surgical margin status, there were no recurrences at the original site in 51 patients with negative horizontal margins. Cox proportional hazard analysis revealed that a positive vertical margin was an independent prognostic factor of worse PFS. On reTUR, six pTa/is residues were detected in patients with a positive horizontal margin, and three pT1 residues were detected in one patient with a positive vertical margin or other adverse pathological features. CONCLUSIONS: A reTUR after ERBT for pT1 bladder cancer appears not to improve either recurrence or progression. Surgical margin status affects prognosis and reTUR outcomes. A reTUR can be omitted after ERBT in patients with pT1 bladder cancer and negative margins; for those with positive horizontal or vertical margins, reTUR should remain the standard until proven otherwise.

BACKGROUND: We aimed to assess the clinical, oncological, and pathological impact of en bloc resection of bladder tumors (ERBT) compared with conventional transurethral resection of bladder tumors (cTURBT) for pT1 high-grade (HG) bladder cancer. PATIENTS AND METHODS: We retrospectively analyzed the record of 326 patients (cTURBT: n = 216, ERBT: n = 110) diagnosed with pT1 HG bladder cancer at multiple institutions. The cohorts were matched by one-to-one propensity scores based on patient and tumor demographics. Recurrence-free survival (RFS), progression-free survival (PFS), cancer-specific survival (CSS), and perioperative and pathologic outcomes were compared. The prognosticators of RFS and PFS were analyzed using the Cox proportional hazard model. RESULTS: After matching, 202 patients (cTURBT: n = 101, ERBT: n = 101) were retained. There were no differences in perioperative outcomes between the two procedures. The 3-year RFS, PFS, and CSS were not different between the two procedures (p = 0.7, 1, and 0.7, respectively). Among patients who underwent repeat transurethral resection (reTUR), the rate of any residue on reTUR was significantly lower in the ERBT group (cTURBT: 36% versus ERBT: 15%, p = 0.029). Adequate sampling of muscularis propria (83% versus 93%, p = 0.029) and diagnostic rates of pT1a/b substaging (90% versus 100%, p < 0.001) were significantly better in ERBT specimen compared with cTURBT specimen. On multivariable analyses, pT1a/b substaging was a prognosticator of disease progression. CONCLUSIONS: In patients with pT1HG bladder cancer, ERBT had similar perioperative and mid-term oncologic outcomes compared with cTURBT. However, ERBT improves the quality of resection and specimen, yielding less residue on reTUR and yielding superior histopathologic information such as substaging.

OBJECTIVE: To assess the association between cystoscopic findings and oncological outcomes in patients with non-muscle-invasive bladder cancer (NMIBC) given that the oncological impact of quantity and quality assessment of tumours with cystoscopy has not been well verified. METHODS: Multiple databases were queried in May 2022 for studies investigating the association of oncological outcomes, such as recurrence-free (RFS), progression-free (PFS), and cancer-specific survival (CSS), with cystoscopic findings, including multiplicity, size, and gross appearance of tumours in patients with NMIBC. RESULTS: Overall, 73 studies comprising 28 139 patients were eligible for the meta-analysis. Tumour multiplicity was associated with worse RFS (pooled hazard ratio [HR] 1.61, 95% confidence interval [CI] 1.48-1.74) and PFS (pooled HR 1.44, 95% CI 1.18-1.76) in NMIBC patients (including both Ta and T1). Tumour size (≥3 cm) was associated with worse RFS (pooled HR 1.97, 95% CI 1.69-2.30) and PFS (pooled HR 1.81, 95% CI 1.52-2.15) in NMIBC patients. In patients with T1 bladder cancer (BCa), tumour multiplicity and size (≥3 cm) were also associated with worse RFS, PFS and CSS. By contrast, among patients treated with bacillus Calmette-Guérin (BCG), tumour multiplicity was not associated with worse RFS, and tumour size (≥3 cm) was not associated with worse PFS. Sessile tumours were associated with worse RFS (pooled HR 2.14, 95% CI 1.52-3.01) and PFS (pooled HR 2.17, 95% CI 1.42-3.32) compared to pedunculated tumours. Compared to papillary tumours, solid tumours were associated with worse RFS (pooled HR 1.84, 95% CI 1.25-2.72) and PFS (pooled HR 3.06, 95% CI 2.31-4.07) in NMIBC patients, and CSS in T1 BCa patients (pooled HR 2.32, 95% CI 1.63-3.30). CONCLUSIONS: Cystoscopic findings, including tumour multiplicity, size, and gross appearance, strongly predict oncological outcomes in NMIBC patients. Cystoscopic visual features can help in the decision-making process regarding the timeliness and extent of tumour resection as well as future management such as intravesical therapy.
