We undertook a systematic evaluation of the prognostic value of numerous histologic factors in 165 radical cystectomies (RC) of patients with invasive urothelial carcinoma who underwent surgery after neoadjuvant chemotherapy (NAC). Tumor regression grade (TRG) and therapy-related stromal and epithelial changes were also recorded. Locally advanced disease (≥pT2 and/or pN+) was present in 64% of patients, 22% had no evidence of residual carcinoma (pT0+pN0) and 28% had no evidence of residual muscle invasive carcinoma (≤pT1+N0)...

INTRODUCTION: Endoscopic management of upper tract urothelial carcinoma has become more popular over the last few decades as there has been an impetus for renal preservation in these patients. While radical nephroureterectomy has been the gold standard in treatment of this disease, ureteroscopic and percutaneous management has become a viable option for select patients. METHODS AND MATERIALS: The literature on endoscopic management of upper urinary tract tumors was explored...

A 54-year-old woman who had been treated with transurethral resection of bladder tumor for nonmuscle invasive urothelial carcinoma approximately nine years before presented with gross hematuria. Cystoscopy demonstrated a papillary tumor at the left side of the ureteral orifice. Magnetic resonance imaging showed a 1.3 cm non-muscle invasive lesion in the lower ureter from the ureteral orifice. She suffered from connective tissue disease treated with steroids. To avoid renal failure, we performed partial ureterectomy and ureteroneocystostomy...

A 71-year-old man was referred to us with a right renal mass that was discovered by computed tomography (CT) examination for acquired hemophilia and leukemoid reaction. He presented with persistent low-grade fever and purpura on the lower legs caused by acquired hemophilia. Contrastenhanced CT scan showed a right renal tumor 6.0×7.4 cm in diameterwith inhomogeneous enhancement. The result of his urine cytology was negative. After improvement of his coagulation by treatment with immunosuppressants and steroids, he underwent open nephrectomy...

In recent years, there has been increased interest in carcinomas of the urologic tract, that demonstrate association with the polyoma virus BK arising in immunosuppressed individuals, though the nature of this association is uncertain. To begin to understand this phenomenon, we reviewed the clinical, morphological, and immunohistochemical features of 11 carcinomas of the urologic tract, mainly urothelial (N = 9) and collecting duct carcinomas (N = 2), occurring during immunosuppression, and expressing polyoma virus T-antigen by immunohistochemistry...

Small cell carcinoma (SmCC) of the bladder is a rare disease. We retrospectively studied a large series of bladder SmCC from a single institution. The patients included 69 men and 12 women with a mean age of 68years. Most bladder SmCC were presented at advanced stage with tumors invading the muscularis propria and beyond (n=77). SmCC was pure in 27 cases and mixed with other histologic types in 54 cases, including urothelial carcinoma (UC) (n=32), UC in situ (n=26), glandular (n=14), micropapillary (n=4), sarcomatoid (n=4), and squamous (n=3), and plasmacytoid (n=1) features...

OBJECTIVE: Long noncoding RNAs (lncRNAs) play important roles in the pathogenesis of bladder cancer. A recent study reported that lncRNA HNF1A-AS1 (HNF1A-AS1) was upregulated in urothelial carcinoma of the bladder (UCB) and served as a tumor promoter. However, the clinical significance of HNF1A-AS1 in the prognosis of patients with UCB was poorly understood. This work was designed to investigate the relationship between HNF1A-AS1 expression level and the prognosis of UCB. PATIENTS AND METHODS: Relative expression levels of HNF1A-AS1 in UCB tissues were determined by qRT-PCR...

BACKGROUND: An important goal of The Paris System for Reporting Urinary Cytology (TPS) is to reduce unnecessary atypical diagnoses given to urinary tract cytology (UTC) specimens. Since implementation of TPS at the study institution in 2016, the institutional atypical rate has declined only slightly. The authors speculated that TPS might not have had an immediate impact because several faculty members were involved in TPS committees and because TPS contains elements that already had been integrated into institutional practice...

The incidence of urothelial carcinoma (UC; formerly transitional cell carcinoma) is higher among renal transplant recipients compared with the general population. Upper urinary tract UC (UUT-UC) of allograft urothelium is a rare event with approximately 40 cases reported in the literature. Herein, we describe the clinical presentation and management of UUT-UC in a transplant ureter 10 years after deceased donor kidney transplantation.

BACKGROUND: Neoadjuvant chemotherapy (NAC) has been shown to improve survival in patients with urothelial carcinoma (UC). However, there are a subset of patients who do not respond or progress despite systemic treatment. METHODS: Data from the National Cancer Database on patients who underwent a radical cystectomy (RC) with or without NAC from 2006 to 2013 were abstracted. Covariates were balanced using inverse probability weighting methods. The primary outcome of overall survival in patients with residual disease by stage was evaluated using 90-day conditional landmark analysis and Cox proportional hazards modeling...

Programmed death ligand-1 (PD-L1) immunohistochemistry is used to guide treatment decisions regarding the use of checkpoint immunotherapy in the management of urothelial carcinoma of the bladder and hypopharyngeal (HP) squamous cell carcinoma. With increasing PD-L1 testing options, a need has arisen to assess the analytical comparability of diagnostic assays in order to develop a more sustainable testing strategy. Using tissue microarrays, PD-L1 expression in tumor cells (TCs) and immune cells (ICs) was manually scored in 197 cases and 27 cases of bladder and HP cancer, respectively...

Hepatic cancer (HCC) is a well-identified dilemma throughout the world, and hence, the molecular mechanisms and strategy for preventive protection against this malignancy are critical. S-adenosylmethionine (SAM) is a unique methyl granter in vast reactions, including DNA methylation, and secures the genome against hypomethylation, which is a hallmark of tumors. Consequently, SAM may control the rate of gene expression. The objective of this investigation was to evaluate the expression of long noncoding RNAs (lncRNAs) transcript involved in hepatic tumorigenesis, including additional coding CEBPA (ecCEBPA) and urothelial carcinoma related 1 (UCA1), antioxidant enzymes transcripts, and relevant signaling pathway in diethylnitrosamine (DEN)-prompted HCC along with their conceivable targeting by SAM at different stages of HCC in rats...

The impact of tumor infiltrating lymphocytes (TILs) on survival was confirmed in various cancer types. Our study aims to investigate the prognostic role of TILs on survival in patients with metastatic urothelial carcinoma (mUC) receiving platinum based chemotherapy. Patients who were diagnosed to have pathologically proved mUC between 1997 and 2016 and received palliative chemotherapy with platinum based regimen were recruited into our study. Kaplan-Meier curves and Cox regression analysis were constructed for overall survival (OS)...
