Article Abstract
Objective: To evaluate the mRNA expression of lymphangiogenesis and proliferation markers and to examine its association with histopathological characteristics and clinical outcome in patients with urothelial carcinoma of the bladder (UCB) after radical cystectomy (RC).
Patients And Methods: Gene expression analysis of the vascular endothelial growth -C and -D (VEGF-C/-D), its receptor VEGF receptor-3 (VEGFR-3), MKI67, and RACGAP1 was performed in 108 patients after radical cystectomy and their correlation with clinical-pathological parameters was investigated. Uni- and multivariate regression analyses were used to identify predictors for cancer-specific survival (CSS), recurrence-free survival (RFS) and overall survival (OS) after RC.
Results: The expression of RACGAP1 and VEGFR-3 showed an association with a higher pT stage (P = 0.049; P = 0.009). MKI67 showed an association with a high-grade urothelial carcinoma of the bladder (P = 0.021). VEGFR-3 expression was significantly associated with the presence of lymphovascular invasion (LVI) (P = 0.016) and lymph node metastases (pN+) (P = 0.028). With the univariate analysis, overexpression of VEGFR-3 (P = 0.029) and the clinical-pathological parameters pT stage (P < 0.0001), pN+ (P = 0.0004), LVI (P < 0.0001) and female gender (P = 0.021) were significantly associated with a reduced CSS. Multivariate analysis identified a higher pT stage (P = 0.017) and LVI (P = 0.008) as independent predictors for reduced CSS. Independent predictors for reduced OS were a higher pT stage (P = 0.0007) and LVI (P = 0.0021), while overexpression of VEGF-D was associated with better OS (P < 0.0001).
Conclusions: The mRNA expression of the investigated markers showed associations with common histopathological parameters. Increased expression of VEGF-D is independently associated with better overall survival.

Real-world Effectiveness of Single-Agent Enfortumab Vedotin in Patients With Advanced Urothelial Carcinoma.

Division of Medical Oncology, Department of Internal Medicine, Huntsman Cancer Institute, University of Utah, Salt Lake City, UT. Electronic address:
Background: Enfortumab vedotin (EV) is a nectin-4-directed antibody and microtubule inhibitor conjugate indicated for patients with metastatic urothelial carcinoma (mUC) who have received prior platinum-based chemotherapy and PD-1/L1 inhibitors or are ineligible for cisplatin-containing regimens and have undergone at least 1 prior line of therapy. EV is also indicated in combination with pembrolizumab in the first-line setting. However, real-world effectiveness of EV based on treatment line and impact of prior therapy remains unclear.

Introduction: Utilization of neoadjuvant systemic therapy (NAT) prior to radical nephroureterectomy (RNU) for upper tract urothelial carcinoma (UTUC) is inconsistent, and optimal patient selection for NAT is unclear. The purpose of this study was to evaluate the clinical benefit of NAT in high grade UTUC undergoing RNU.
Materials And Methods: The UTUC Collaborative Network (UCAN) identified patients who underwent RNU for high grade UTUC between 2000 and 2022.
Urothelial carcinoma in situ with "early papillary formation" vs "lateral spread/shoulder lesion" of prior high-grade noninvasive papillary urothelial carcinoma: A survey of pathologist and urologist interpretations.
Am J Clin Pathol

Department of Pathology and Laboratory Medicine, Cleveland Clinic Foundation, Cleveland, OH, United States.
Objectives: Urothelial carcinoma in situ (CIS) with early papillary formation is terminology sometimes used to suggest incipient high-grade papillary urothelial carcinoma (PUC) but may lead to confusion between true CIS and lateral flat spread of PUC.
Methods: It remains unclear how pathologists and urologists interpret this scenario, so a survey was circulated to 68 pathologists (group 1 = 28 academic genitourinary pathologists; group 2 = 17 pathologists with a self-reported genitourinary focus; group 3 = 23 pathologists self-reported as not genitourinary specialists) and 32 urologists.
Results: Regarding atypical urothelial lesions that appear mainly flat but contain possible papillae, group 3 was more likely to label this as CIS compared with groups 1 and 2 (35% for group 3 vs 13% for groups 1 and 2), while groups 1 and 2 more often adopted another descriptive diagnosis, such as "CIS with early papillary features" (38% for groups 1 and 2 vs 13% for group 3).
Increased ratio of red cell distribution width to lymphocyte percentage as a new preoperative marker for unfavorable survival outcomes in upper tract urothelial carcinoma.

The aim of the present study was to determine the prognostic significance of a novel marker, the red cell distribution width to lymphocyte percentage (RDW-to-LYM%) ratio, in patients with upper tract urothelial carcinoma (UTUC) after radical nephroureterectomy (RNU). The clinical and follow-up data of 625 patients with UTUC receiving RNU were retrospectively analyzed. The optimal cut-off value of the pre-treatment RDW-to-LYM% ratio was determined as 0.

Background: After failure of first-line chemotherapy, standard of care for advanced urothelial cancer (aUC) is immune checkpoint inhibitors (ICIs) targeting PD-1/PD-L1 pathway. Several prognostic models (Bajorin and Bellmunt scores) have been evaluated, but only in the context of chemotherapy.
Objective: To study whether the variables in these scores and new emerging clinical and biological criteria have an impact on the probability of objective response in aUC treated with ICIs in 2nd-line setting and beyond.
