Urothelial carcinoma is one of the most frequently diagnosed malignant tumors of the bladder and upper urinary tract, which ranks seventh in the pattern of cancer. Urothelial carcinoma of the renal pelvis is less common; but has a more aggressive clinical course and a worse prognosis than that of the bladder. This is due to the clinical and morphological features of this form of cancer, which, unlike bladder cancer, have not been studied enough. OBJECTIVE: To comparatively analyze the morphological and immunophenotypic parameters of urothelial carcinomas of the renal pelvis and bladder...

Fibroblast growth factors (FGF) 19, 21, and 23 have been reported as functional factors in human metabolic diseases and malignancies. We performed a prospective survey to compare circulating FGF levels in urothelial carcinoma (UC) patients and normal controls. Between 2016 and 2017, 39 patients with UC of the urinary bladder or upper urinary tract who received surgical intervention were included. All the serum samples were obtained before surgeries. The control group included 28 healthy volunteers. Analysis of the circulating FGF19, 21, and 23 levels among all 67 subjects, as well as a subgroup analysis of the 39 UC patients were performed...

OBJECTIVES: To evaluate the survival benefits that lymph node dissection (LND) brought to clinically node-negative upper tract urothelial carcinoma (UTUC) patients. METHODS: Non-metastatic node-negative UTUC patients were identified from the Surveillance, Epidemiology and End Results database. N0 patients were naturally divided as cN0-pNx group (clinically diagnosed as N0 without LND performed) and cNx-pN0 group (pathologically diagnosed as node-negative no matter what clinical node status they have)...

OBJECTIVES: To compare renal function after radical nephrectomy for renal cell carcinoma (RCC) and for upper tract urothelial carcinoma (UTUC). METHOD: Data from 1,236 patients with RCC or UTUC treated surgically from 2000 to 2013 were enrolled. The estimated glomerular filtration rate (eGFR) was calculated preoperatively and postoperatively at 12, 24, 36, 48, and 60 months. A multivariate logistic regression was used to determine independent factors for a decrease in eGFR to < 60 mL/min/1...

OBJECTIVES: To analyze the potential survival benefit of perioperative chemotherapy (CHT) in patients treated with nephroureterectomy (NU) for non-metastatic locally advanced upper tract urothelial carcinoma. METHODS: Within the Surveillance, Epidemiology, and End Results database (2004-2014), we identified 1286 patients with T3 or T4, N 0-3 M0 UTUC. Kaplan-Meier plots, as well as multivariable Cox regression models (MCRMs) relying on inverse probability after treatment weighting (IPTW) and landmark analyses, were used to test the effect of CHT vs no CHT on overall mortality (OM) in the overall population (n =1286), as well as after stratification according to lymph node invasion (LNI)...

While pelvic lymphadenectomy during radical cystectomy for bladder cancer is a well-established standard of care, the same does not hold true for upper tract urothelial carcinoma (UTUC). Indeed, a template-based lymphadenectomy is rarely, if ever, performed in conjunction with radical nephroureterectomy at most centres across the globe. While multiple studies have explored the staging and therapeutic role of lymphadenectomy in cases of UTUC, there remain large gaps in our understanding of the indications, extent and safety of this procedure as an adjunct to nephroureterectomy...

AIMS: Immunohistochemical (IHC) staining for CK5/6, CD44, and CK20 has been significantly associated with the prognosis of urinary bladder urothelial carcinoma and probably reflects its molecular characteristics. Because of its rarity, the IHC-based subgroups and their prognostic effects on upper tract urothelial carcinoma (UTUC) are still unclear, especially in non-muscle-invasive papillary UTUC. METHODS AND RESULTS: IHC staining for CK5/6, CK20, and CD44 was analyzed in 211 patients with non-muscle-invasive papillary UTUC...

PURPOSE: While radical nephroureterectomy (RNU) is the gold standard treatment for upper tract urothelial carcinoma (UTUC), select patients may benefit from endoscopic treatment (ET). European Association of Urology guidelines recommend ET for patients with low-risk (LR) disease: unifocal, < 2 cm, low-grade lesions without local invasion. To inform the utility of ET, we compare the overall survival (OS) of patients receiving ET and RNU using current and previous guidelines of LR disease...

BACKGROUND: Few studies examined the rates of guideline implementation and the survival effect of bladder cuff excision (BCE) at nephroureterectomy (NU). OBJECTIVE: To assess the rates of guideline implementation regarding NU with BCE relative to NU without BCE in patients with upper tract urothelial carcinoma (UTUC) and to test the effect of BCE on cancer-specific (CSM) and other-cause mortality (OCM). DESIGN, SETTING, AND PARTICIPANTS: We relied on Surveillance, Epidemiology, and End Results database (2004-2014) for UTUC of the renal pelvis patients (T1-T3, N0, M0) treated with NU with or without BCE...

Common iliac artery (CIA) thrombosis is a rare surgical complication which may cause serious leg damage and may occasionally be fatal. We experienced two cases of CIA thrombosis in nephroureterectomy with the pluck technique for upper tract urothelial carcinoma. Patients were treated using emergent femoro-femoral bypass, and one patient was treated with fasciotomy of the lower extremity for compartment syndrome. CIA thrombosis is considered a possible complication of nephroureterectomy, particularly with the pluck technique in open surgery...

Current literature supports the efficacy of anti-PD-1 and anti-PD-L1 immune checkpoint inhibitors for the treatment of urothelial carcinomas. While the prognostic value of PD-1 and PD-L1 levels has been comprehensively analyzed for urothelial carcinoma of the bladder, less is known for upper tract urothelial carcinoma. In addition, available data on the prognostic value of PD-1 and/or PD-L1 level in the tumor and/or peritumoral microenvironment are heterogeneous and even sometimes contradictory. In this article, we compared the methodologies of the various available studies in order to highlight the factors that can explain these discordant results...
