Visfatin, a newly discovered adipocytokine, is a pro-inflammatory cytokine. This study aimed to evaluate the predictive value of visfatin on prognosis of patients with upper tract urothelial carcinoma. One-hundred and five patients (median age=64, range=24-84 years) were included in this study. Visfatin expression in upper tract urothelial carcinoma tissues was analyzed by immunohistochemistry....
BACKGROUND AND OBJECTIVES We evaluated the incidence of tumor recurrence following hand-assisted laparoscopic nephroureterectomy (HALNU) for the treatment of upper tract urothelial carcinoma. METHODS The medical records of consecutive patients who underwent HALNU by a single surgeon (CW) between October 2001 and May 2005 were reviewed. The ureter was clipped before kidney dissection to preven...
BACKGROUND Bladder cancer represents the fifth most common malignancy worldwide and a major cause of cancer-related morbidity and death. Incidence and mortality rates have remained relatively constant over the past four decades. Urothelial bladder cancers have identified multiple risk factors. AIM We aimed at evaluating the expression of the FGFR3 protein and gene amplification in the urothel...
Anterior gradient 2 (AGR2) is a cancer-associated secreted protein found predominantly in adenocarcinomas. Given its ubiquity in solid tumors, cancer-secreted AGR2 could be a useful biomarker in urine or blood for early detection. However, normal organs express and might also secrete AGR2, which would impact its utility as a cancer biomarker. Uniform AGR2 expression is found in the normal bladd...
Extrarenal rhabdoid tumors have been described in a variety of primary sites with only rare case reports of urothelial carcinomas with rhabdoid features in the literature. In this report, we describe the clinicopathologic characteristics, including clinical follow-up on 6 cases of urothelial carcinoma with prominent rhabdoid features. Four cases were retrieved from the consultation files of one...
BACKGROUND Light microscopic evaluation of cell morphology in preparations from urine or bladder washing containing exfoliated cells is a standard and primary method for the detection of bladder cancer and also malignancy from other parts of the urinary tract. The cytopathologic examination is a valuable method to detect an early recurrence of malignancy or new primary carcinoma during the foll...
Microscopic patterns of thirty-four urothelial tumors of the urinary bladder of water buffaloes from the Marmara and Black Sea Regions of Turkey are here described. All the animals grazed on lands rich in bracken fern. Histological diagnosis was assessed using morphological parameters recently suggested for the urinary bladder tumors of cattle. Papillary carcinoma was the most common neoplastic...
BACKGROUND Upper urinary tract cancer is typically diagnosed with urine cytology and imaging techniques. These assays can be limited by sensitivity, specificity, or technical issues making some diagnoses difficult. CASE PRESENTATION A 73-year old man presented to the clinic with a right renal pelvis filling defect that was detected by a CT-scan performed for unrelated reasons. Urine cytology ...
Several small single-center studies have reported a prognostic role for Ki-67 labeling index in advanced urothelial carcinoma of the urinary bladder. To investigate whether Ki-67 was a useful biomarker of oncological outcome after radical cystectomy for urothelial carcinoma, we assessed its expression in tumor tissue from 713 patients treated with radical cystectomy and bilateral lymphadenectom...
abstract synchronous upper urinary tract tumor and superficial bladder tumor are uncommon. this is a report of a 62- year- old man presented with episode of painless gross hematuria and flank pain. we worked him up and found a left renal mass and bladder lesion. he underwent nephrectomy and tur-bt, and the pathology report of both showed a high grade urothelial transitional cell carcinoma. th...
