INTRODUCTION: Bladder mucosa is anatomically covered by urothelial epithelium. The replacement of the urothelium with stratified squamous cells is defined as squamous metaplasia which can be keratinizing or non-keratinizing. Clinically, it is also known as leukoplakia or keratinizing cystitis of the bladder. Although several etiologic factors have been proposed such as chronic inflammation, irritative stimuli and infection, its pathogenesis is not clearly understood. The natural history of squamous metaplasia and clinical treatment are controversial...

Increasing evidence indicates that microRNAs (miRNAs) have essential roles in various biological processes, including proliferation, migration, invasion, cell cycle progression and apoptosis. It is considered that miRNA de-regulation contributes to tumor progression and metastasis in various cancers, and MiR-203a has been identified as a tumor suppressor in cancers, such as glioma, gastric cancer and hepatocellular carcinoma. Herein, we established that miR-203a expression is significantly lower in bladder cancer tissues than in adjacent normal tissues, and that low miR-203a expression is associated with poor patient outcome...

The aim of our study was to retrospectively report on radiotherapy (RT) in the oligometastastic recurrence of bladder cancer. Thirteen patients treated for low-volume metastatic transitional cell urinary bladder carcinoma (TCC) were reviewed. The primary endpoint was to evaluate the safety and efficacy of RT, proposed as an alternative to systemic treatment and/or to defer the start of a systemic therapy. Inclusion criteria for our retrospective study were as follows: patients that received RT (without other local/systemic therapy) for oligometastatic TCC with lymph node, bone, lung lesions or local recurrence...

Androgen receptor (AR) activation plays an important role in the promotion and progression of urothelial tumorigenesis. Also, dysregulation of the Wnt/β-catenin signaling pathway has also been linked to bladder cancer growth. However, cross talk between the two pathways in remains unclear in bladder cancer. This study investigated the prognostic significance of AR and β-catenin expression and their relationship to different clinic-pathological parameters, recurrence free and progression free survival. 106 urothelial carcinoma cases were used to study the immunohistochemical expression of AR and β-catenin...

Paget's disease of the vulva is a rare intraepithelial neoplasm, accounting for <5% of all vulvar lesions. The underlying mechanisms of this disease are still poorly understood, however, diagnosing a Pagetoid lesion early is of prime importance as it may forewarn an underlying systemic malignancy. We discuss the case of an elderly female who was being conservatively treated for infectious lesion of the lower urinary tract and vulva for months. She was subsequently confirmed on histopathology with vulvar Paget's and underlying urothelial carcinoma, with the help of an extensive panel of immunohistochemistry...

BACKGROUND/AIM: Prognoses of patients with metastatic epidural spinal cord compression (MESCC) from urothelial carcinoma of the bladder are generally poor. This study aimed to identify prognostic factors that can facilitate personalized care of these patients. PATIENTS AND METHODS: In 46 patients, 10 factors were evaluated for overall response (OR), post-radiotherapy (RT) ambulatory status, local control of MESCC and overall survival (OS). Independent predictors of OS were incorporated in a scoring system...

Hepatic carcinoma (HC) is one of the most prevalent cancers, ranked as the second most common cause of cancer related deaths worldwide. Silymarin (SYL) has been reported for its anticarcinogenic activity against various types of cancer such as prostate, breast, ovary, colon, lung, bladder and liver. Due to poor solubility and low bioavailability SYL lacks satisfactory therapeutic value thus designing a suitable and effective delivery system of SYL can led to improved therapeutic potential. The present study was aimed to develop SYL loaded dextrose (DEX) modified bilosomes for targeted delivery to HC cells...

Lower urinary tract neoplasia in companion animals is a debilitating and often life-threatening disease. Tumors of the bladder, urethra, and prostate often occur independently, although extension of these tumors into adjacent regions of the lower urinary tract is documented frequently. The most common lower urinary tract tumor in dogs and cats is transitional cell carcinoma (TCC). In both dogs and cats, TCC affecting the urinary bladder is generally considered to be highly aggressive with both local and metastatic disease potential, and this disease poses unique treatment challenges...

USP28, a member of the deubiquitinating enzymes family, plays a vital role in the physiological process of cell proliferation, differentiation and apoptosis, DNA repair, immune response, and stress response. USP28 has been reported to be overexpressed in bladder cancer, colon cancer, breast carcinomas, and so on. Nevertheless, the role of USP28 in gastric cancer has not yet been investigated. In our study, we examined the USP28 expression in 87 paired samples of gastric cancer and normal gastric tissues. We found that USP28 was overexpressed in gastric cancer compared with normal gastric tissues (P < 0...

Muscle-invasive urothelial carcinoma of the urinary bladder (UCB) often recurs following radical cystectomy (RC). An altered expression of sex-steroid hormone receptors has been associated with oncological outcomes of UCB and may represent therapeutic targets. Here the expression of different hormone receptors was measured on mRNA levels in patients treated by RC and associated with outcomes. Androgen receptor (AR), estrogen receptor 1 (ESR1), and progesterone receptor (PGR) mRNA expression was assessed by quantitative reverse transcription polymerase chain reaction (RT-qPCR) in RC samples of 87 patients with a median age of 66 (39-88) years...

Bladder cancer is frequently occurred in urinary system and has complicated pathogenesis factors including both genetics and environmental factors that have not been fully illustrated. Hypoxia can further induce tumor progression. ROCK2 has abnormal expression in various tumors but its expression or functional role in bladder cancer have not been illustrated. In vitro cultured bladder cancer cell line T24 was randomly assigned into control group, hypoxia group (prepared under hypoxic culture), and ROCK2 siRNA group (transfected with ROCK2 siRNA after hypoxia treatment)...

Benign urachal remnants can be encountered in the adult urinary bladder and it is recognized that these can uncommonly give rise to urachal urothelial carcinoma. However, urachal remnants containing urothelial carcinoma incidentally encountered in cystectomies for bladder cancer has not been previously described. Herein, we present 8 adult bladder cancer cystectomies with incidental urachal remnants containing urothelial carcinoma. All 8 incidental urachal remnants with tumor were located at the dome that varied from small tubular to tubulocystic structures and contained urothelial carcinoma in situ (CIS) (6), noninvasive high-grade papillary urothelial carcinoma (PUC) (1), and coexistent noninvasive high-grade PUC and urothelial CIS (1)...

Although fistulae between the urinary bladder and the gastrointestinal tract are not uncommon, those caused by carcinoma of the urinary bladder are rare. This report describes the case of an 85 years old male who was diagnosed with a mass involving the small bowel and the urinary bladder during the course of investigation for recurrent urinary tract infections. At laparotomy, the presence of an enterovesical fistula involving the ileum and bladder was confirmed. Histopathological examination of the resected mass showed poorly differentiated urothelial carcinoma...

Small cell carcinoma (SCC) of the urinary bladder is highly aggressive and portends a poor outcome. Herein, we report a patient with recurrent SCC of the urinary bladder who experienced an unusually long-term disease-free duration after radical cystectomy. The patient was a 60-year-old woman who had undergone transurethral resection followed by radical cystectomy for muscle-invasive bladder cancer (high-grade urothelial carcinoma with adenocarcinomatous differentiation) 6 years prior; the surgical specimen had a negative surgical margin...

Urachal cancer is a rare but aggressive disease. In addition to the non-glandular tumors, non-cystic urachal adenocarcinomas are nowadays distinguished from the primary cystic variant. (Immunohistochemical) markers are only of minor differential diagnostic value and, therefore, the diagnosis is primarily established in a multidisciplinary approach. The non-cystic variant accounts for the majority of cases (83%), is more common in men (63%), shows a median age at diagnosis of 51 years and has a 5-year survival rate of about 50%...
