Carcinosarcoma of the upper urinary tract is very rare. In this article, we report a case of upper urinary tract carcinosarcoma with rhabdomyoblastic differentiation showing distinct transition between the epithelial and mesenchymal components confirmed by morphology and immunohistochemistry. An 81-year-old female underwent radical nephroureterectomy under the diagnosis of left ureteral urothelial carcinoma (UC). Multiple invasive tumors showed combined histology with UC and rhabdomyosarcomatous elements (pT2-ureter and pT3-renal pelvis, pN0, u-lt0, ly0, v0, RM0)...

BACKGROUND: To determine the predictive value of preoperative lymphocyte-to-monocyte ratio (LMR) for pathological and survival outcomes in upper tract urothelial carcinoma (UTUC) after radical nephroureterectomy (RNU). METHODS: This retrospective study included 704 UTUC patients between 2008 and 2017. We used a cutoff LMR of 3.6 to evaluate its relationship with oncological outcomes after RNU, using the Kaplan-Meier method and logistic regression models. RESULTS: During median follow-up of 39 months, decreased preoperative LMR was an independent predictor of poor pathological outcomes...

INTRODUCTION: Upper tract urothelial carcinoma (UTUC) accounts for <5% of all urothelial cancers. We aimed to ascertain the clinical differences between UTUC tumours presenting de novo (DnUTUC) and those presenting secondary (SUTUC) following a bladder cancer diagnosis. METHODS: Our institutional database was queried for all UTUC patients who were surgically treated with radical nephroureterectomy or ureterectomy between 2003 and 2017. Bladder recurrence and cancer-specific mortality were compared...

PURPOSE OF REVIEW: Our aim is to review recent investigations into the recurrence of urothelial carcinoma in the upper urinary tract following bladder cancer therapy focusing on surveillance and management. RECENT FINDINGS: After radical cystectomy, rates of recurrence in the upper tract are between 0.75 and 6.4%. The poor prognosis of upper tract urothelial carcinoma (UTUC) is in part attributable to delayed diagnosis. Guidelines recommend a gradual de-escalation of surveillance in disease-free patients with the potential for discontinuation beyond 5 years...

Sarcopenia, which represents the degenerative and systemic loss of skeletal muscle mass, is a multifactorial syndrome caused by various clinical conditions. Sarcopenia reflects not only frailty and poor general health status, but also the possible presence of advanced or progressive cancer or cancer cachexia. Therefore, sarcopenia affects the management of cancer-bearing patients, including those with urothelial carcinoma. Recently, growing evidence has shown that sarcopenia is significantly associated with higher rates of treatment-related complications and worse prognosis in patients with urothelial carcinoma, including muscle-invasive bladder cancer, upper tract urothelial carcinoma, and advanced urothelial carcinoma...

Objective: Growing evidence suggests pretreatment fibrinogen can serve as a prognostic marker in various malignancies. However, there are contradictory results about the prognostic role of fibrinogen in urological cancers. We conducted a meta-analysis to evaluate the association between pretreatment plasma fibrinogen and survival outcomes in urological cancers. Methods: After a systematic search of PubMed and Embase, we included 14 studies in our meta-analysis, and estimated hazard ratios (HRs) for overall survival (OS) and cancer-specific survival (CSS) using a fixed-effect model...

Immunohistochemical (IHC) staining for CK5/6 and CK20 was reported to be correlated with the prognosis of early urothelial carcinoma in a way contrary to that of advanced tumors for unknown reasons. We aimed to characterize the gene expression profiles of subgroups of non-muscle-invasive papillary high-grade upper tract urothelial carcinoma (UTUC) classified by CK5/6 and CK20 expression levels: group 1 (CK5/6-high/CK20-low), group 2 (CK5/6-high/CK20-high), and group 3 (CK5/6-low/CK20-high). Expression of group 3 was predictive of worse prognosis of non-muscle-invasive papillary high-grade UTUC...

Bladder cancer is the fourth most common cancer in men and the ninth most common in women in the Western world. The management of bladder carcinoma requires a multidisciplinary approach. Optimal treatment depends on several factors, including histology, stage, patient status, and possible comorbidities. Here we review recent findings on the treatment of muscle-invasive bladder carcinoma, advanced urothelial carcinoma, upper tract urothelial carcinoma, non-urothelial carcinoma, and urologic complications arising from the disease or treatment...

Upper tract urothelial carcinoma (UTUC) accounts for 5% of urothelial carcinomas (UCs), the estimated annual incidence being 1-2 cases per 100,000 inhabitants. Similarly to bladder UC, divergent differentiations and histologic variants confer an adverse risk factor in comparison with pure UTUC. Molecular and genomic characterization studies on UTUC have shown changes occurring at differing frequencies from bladder cancer, with unique molecular and clinical subtypes, potentially with different responses to treatment...

Upper tract urothelial carcinoma (UTUC) is a relatively uncommon cancer worldwide, however it accounts for approximately 30% of urothelial cancer in the Taiwanese population. The aim of the current study is to identify differential molecular signatures and novel miRNA regulations in UTUC, using next-generation sequencing and bioinformatics approaches. Two pairs of UTUC tumor and non-tumor tissues were collected during surgical resection, and RNAs extracted for deep sequencing. There were 317 differentially expressed genes identified in UTUC tissues, and the systematic bioinformatics analyses indicated dysregulated genes were enriched in biological processes related to aberration in cell cycle and matrisome-related genes...

BACKGROUND: Metabolic adaptation in cancer cells is important for cancer cell survival. Alternation in cellular metabolism getting more energy to support cell proliferation played a critical role in disease progression. We initially analyzed the public transcriptome of urothelial carcinoma in Gene Expression Omnibus database (GSE31684) with particular focus on genes associated with carbohydrate metabolism, and found that Chitinase 3-like-1 (CHI3L1) was a significantly up-regulated gene associated with advanced disease status...
