Abstract
PURPOSE To evaluate the impact of variant histology on patients with upper tract urothelial carcinoma (UTUC) survival outcomes. MATERIALS AND METHODS A total of 519 patients underwent radical nephroureterectomy without neoadjuvant therapy for UTUC at a single institution between May 2003 and December 2019. Multivariate Cox regression analysis evaluated the impact of variant histology on progression-free survival (PFS), cancer-specific survival (CSS), and overall survival (OS). RESULTS Among 84 patients (16.2%) with variant histology, the most frequent variant type was squamous cell differentiation (64.3%), followed by glandular differentiation (25.0%) and sarcomatoid variant (2.4%). They showed pathologically advanced T stage (for ≥ T3, 59.5% vs 33.3%, p < 0.001), higher tumor grade (96.4% vs 85.7%, p = 0.025), and higher rates of lymph node metastasis (17.9% vs 7.8%, p = 0.015), angiolymphatic invasion (41.7% vs 25.7%, p = 0.003), tumor necrosis (57.1% vs 29.0%, p < 0.001) and positive surgical margin (13.1% vs 5.7%, p = 0.015). On multivariate Cox regression analyses, variant histology was significantly associated with worse PFS (hazard ratio [HR] 2.23; 95% confidence interval [CI] 1.55-3.21; p < 0.001), CSS (HR 2.67; 95% CI 1.35-5.30; p = 0.005) and OS (HR 2.22; 95% CI 1.27-3.88; p = 0.005). In subgroup analysis, no significant survival gains of adjuvant chemotherapy occurred in patients with variant histology. CONCLUSIONS Variant histology was associated with adverse pathologic features and poor survival outcomes. Our results suggest that patients with variant histology may require a close follow-up schedule and novel adjuvant therapy other than chemotherapy postoperatively.

Effectiveness of Adjuvant Chemotherapy in Variant Histology Upper Tract Urothelial Carcinoma Following Radical Nephroureterectomy: Stabilized Inverse Probability Treatment Weighting Analysis of Single Center Experience. Clin Genitourin Cancer 2024:102069. [PMID: 38580522 DOI: 10.1016/j.clgc.2024.102069] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/14/2023] [Revised: 01/04/2024] [Accepted: 02/21/2024] [Indexed: 04/07/2024]
Abstract
PURPOSE The study aimed to investigate the impact of adjuvant chemotherapy on time to recurrence (TTR) and overall survival (OS) in patients with histologic variants of upper tract urothelial carcinoma (VUTUC) following radical nephroureterectomy (RNU). MATERIALS AND METHODS A retrospective review of 131 VUTUC patients' medical records, from a pool of 368 non-metastatic localized or locally advanced UTUC cases, treated at a single tertiary referral center between January 2011 and January 2021. The intervention was adjuvant chemotherapy administration post-RNU. TTR and OS were evaluated using Kaplan-Meier and Cox proportional hazard regression, covariates adjusted for age, postoperative GFR, history of neoadjuvant chemotherapy, T and N stage with stabilized inverse probability of treatment weighting (sIPTW). RESULTS The application of adjuvant chemotherapy showed a significant extension in TTR (P = .01), but no substantial impact on OS (P = .19) after sIPTW adjustment for covariates. Multivariate analysis revealed adjuvant chemotherapy, tumor size, and lymphovascular invasion as significant prognostic factors for TTR. In contrast, only tumor size and perineural invasion were significant for OS. Adjuvant chemotherapy reduced the progression risk in certain VUTUC subtypes (squamous or glandular/micropapillary), but not in sarcomatoid variants. CONCLUSIONS Adjuvant chemotherapy appears to improve TTR, albeit without a significant effect on OS, in nonmetastatic localized and locally advanced VUTUC patients post-RNU. While beneficial to some VUTUC subtypes, it did not yield significant advantages for sarcomatoid variants. Despite adjustments for known confounders, the study's findings may be subject to potential selection bias and unmeasured confounding factors.

Urol Oncol 2024; 42:69.e1-69.e9. [PMID: 38151426 DOI: 10.1016/j.urolonc.2023.12.006] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/17/2023] [Revised: 11/05/2023] [Accepted: 12/04/2023] [Indexed: 12/29/2023]
Abstract
OBJECTIVE To investigate the prognostic impact of variant histology (VH) on survival outcomes in upper tract urothelial carcinoma (UTUC) patients after radical nephroureterectomy (RNU). MATERIALS AND METHODS Data from 635 UTUC patients who underwent RNU at our institution from May 2003 to June 2019 were retrospectively acquired and analyzed. After propensity score matching (PSM), we investigated the impact of VH on overall survival (OS) and cancer-specific survival (CSS) by using cumulative incidence plots with the log-rank test, Cox regression models, and competing risk regression models. RESULTS Overall, 121 (19.1%) patients were diagnosed with VH, including 68 (10.7%) with squamous cell differentiation (SCD) and 28 (4.4%) with adenocarcinoma differentiation (AD). After PSM, the presence of VH was significantly associated with worse OS (HR 1.70, 95% CI 1.25-2.32) and CSS (HR 1.64, 95% CI 1.17-2.31) only in locally advanced UTUC patients (pT>2). In the subgroup analysis, SCD revealed inferior outcomes (OS: HR 1.81, 95% CI 1.28-2.57; CSS: HR 1.73, 95% CI 1.18-2.54) compared with pure urothelial carcinoma (pUC), whereas AD conferred comparable outcomes. In addition, compared with pUC patients, SCD patients with extensive squamous components had significantly decreased OS (HR 4.17, 95% CI 1.84-9.44) and CSS (HR 1.10, 95% CI 0.61-1.99), whereas those with regional squamous components had similar survival outcomes. CONCLUSION For UTUC patients after RNU, the presence of VH is associated with aggressive clinicopathological features and inferior survival outcomes. However, the survival outcomes of localized UTUC patients (pT≤2) with VH, and patients with the AD or regional SCD subtype are comparable to those of patients with pUC.

Intravesical recurrence factors and outcome after radical nephroureterectomy for upper tract urothelial carcinoma: Multivariate analysis with propensity score matching. Front Oncol 2022; 12:984014. [PMID: 36059684 PMCID: PMC9433701 DOI: 10.3389/fonc.2022.984014] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/01/2022] [Accepted: 07/29/2022] [Indexed: 11/13/2022] Open
Abstract
ObjectiveThe risk factors for intravesical recurrence (IVR) after radical nephroureterectomy (RNU) in patients with upper tract urothelial carcinoma (UTUC) remain inconsistent and unclear. Thus, the risk factors of IVR after RNU and the prognostic significance of the risk indicators were explored herein.MethodsWe retrospectively analyzed UTUC patients upon RNU in our center from January 2009 to December 2019. After propensity score matching, 139 patients were included in this study. Univariate and multivariate Cox proportional hazard regressions were used to estimate the hazard ratio and 95% confidence intervals. Overall survival (OS), cancer-specific survival (CSS) and recurrence-free survival (RFS) were measured using the Kaplan–Meier curve with a log-rank test. A P-value < 0.05 was considered statistically significant.ResultsWe included 139 patients with a median follow-up of 42 months, of which 48 patients had an intravesical recurrence. Multivariate Cox regression analysis showed cytological abnormalities in urine (HR=3.101, P=0.002), hydronephrosis (HR=1.852, P=0.042), adjuvant chemotherapy (HR=0.242, P<0.001), and previous history of bladder cancer (HR=5.51, P<0.001) were independent risk factors for IVR. As for clinical outcomes, OS and CSS suggested disadvantages in patients with IVR compared with patients without recurrence (P=0.042 for OS, P<0.0001 for CSS), OS of patients with abnormal urine cytology and OS and CSS of patients receiving adjuvant chemotherapy did not present clinical significance, and other risk factors all affected the clinical outcome.ConclusionIn this propensity-score matching study, cytological abnormality of urine, hydronephrosis, adjuvant chemotherapy and previous history of bladder cancer were shown to be independent risk factors for IVR. Moreover, risk factors also influence clinical outcomes, thereby rendering it necessary to adopt more active postoperative surveillance and treatment strategies for these patients, which may help improve treatment outcomes.
