Upper urinary tract urothelial carcinoma (UTUC) is relatively uncommon. In this article, we review prognostic factors, criteria and indications for treatment with the available modalities using contemporary data. A systematic search on PubMed was performed using the keywords 'upper tract urothelial carcinoma', 'upper tract transitional cell carcinoma', 'nephroureterectomy', 'laparoscopic', 'endoscopic' and 'prognostic factor'. The literature on UTUC is scarce. No prognostic factors have been formally validated in either the diagnosis or treatment of UTUC. The gold-standard management for invasive UTUC is radical nephroureterectomy with a bladder-cuff excision. Laparoscopic and endoscopic approaches represent alternatives in properly selected individuals. Segmental ureterectomy may also be considered. The extent and role of lymph node dissection remains to be validated. Chemotherapy may also be considered in select patients. Additional multi-institutional studies are needed to identify and validate prognostic factors that can predict the outcomes of patients diagnosed with UTUC. Randomized controlled trials are needed to assess the efficacy of the treatment modalities.

Background: Urothelial carcinoma (UC) is a common type of malignant disease; however, the diagnostic and prognostic markers of upper urinary tract urothelial cancer (UTUC) remain poorly understood because of its rarity.
Methods: To clarify the clinicopathological significance of granulocyte-colony stimulating factor (G-CSF) in UTUC, we analyzed the expression and distribution of G-CSF in 112 upper tract urothelial carcinoma (UTUC) samples with immunohistochemistry.
Results: In normal urothelium, G-CSF expression was weak or absent, whereas high expression of G-CSF was observed in UTUC tissues, both in tumor cells (TCs) and stromal cells (SCs).

Background: The apparent diffusion coefficient (ADC) has been reported as a quantitative biomarker for assessing the aggressiveness of upper urinary tract urothelial carcinoma (UTUC), but it has typically been used only with mean ADC values. This study aims to develop a radiomics model using ADC maps to differentiate UTUC grades by incorporating texture features and to compare its performance with that of mean ADC values.
Methods: A total of 215 patients with histopathologically confirmed UTUC were enrolled retrospectively and divided into training and test sets.

Introduction: Neoadjuvant cisplatin-based chemotherapy followed by radical surgery is the standard treatment for muscle-invasive urothelial carcinoma (MIUC). The Checkmate-274 and AMBASSADOR trials have demonstrated improvements in disease-free survival (DFS) with adjuvant immunotherapy. Consequently, this meta-analysis aimed to assess the effectiveness of strategies involving checkpoint inhibitors in managing high-risk MIUC.

Bladder cancer is one of the main causes of urogenital cancer (30-35% of the total urological cancers). Although metastases from urologic tumors are rare, it is associated with a high mortality rate. The location and pattern of metastasis are random and unpredictable.

Urothelial carcinoma (UC) can arise from either the lower urinary tract or the upper tract; they represent different disease entities and require different clinical treatment strategies. A full understanding of the cellular characteristics in UC may guide the development of novel therapies. Here, we performed single-cell transcriptome analysis from four patients with UC of the bladder (UCB), five patients with UC of the ureter (UCU), and four patients with UC of the renal pelvis (UCRP) to develop a comprehensive cell atlas of UC.
