Cancer of the bladder comprises 5.2% of all malignancies and it is the fifth common malignancy in Iran. Transitional cell carcinoma represents 92% of all bladder tumors. Voided urine cytology and cystoscopic biopsy are used for screening and final diagnosis respectively in Iran. Selection of the therapy is according to the tumor grade which is detected by bladder biopsy. The hypothesi...
PURPOSE To the assess sensitivity and specificity of urinary levels of hyaluronic acid (HA) and hyaluronidase (HAase) as an individual or a combined test to diagnose bladder transitional cell carcinoma (TCC). MATERIALS AND METHODS One hundred and ninety-four urine specimens were collected from individuals between July 2007 and March 2008. The urinary level of hyaluronic acid (HA) was measured...
background : e-cadherin is a trans-membrane glycoprotein that plays a critical role in many aspects of cell adhesion as well as establishment and maintenance of epithelial cell polarity. loss of the adhesive function of e-cadherin seems to promote invasive and metastatic properties of neoplastic cells. objectives: the present study is a retrospective study aiming to evaluate the loss of e-cad...
Prostatic adenocarcinoma rarely may involve the urinary bladder. Prostatic adenocarcinoma and highgrade transitional cell carcinoma (TCC) may coexist and account for the malignant cells seen in urinary cytology. Differentiating prostatic adenocarcinoma cells from those of TCC is important for therapy but remains difficult. A 10-year retrospective search identified 250 patients with high-grade c...
Genetic and epigenetic alterations have been identified as to contribute directly or indirectly to the generation of transitional cell carcinoma of the urinary bladder (TCC-UB). In a comparative fashion much less is known about copy number alterations in TCC-UB, but it appears that amplification of chromosome 6p22 is one of the most frequent changes. Using fluorescence in situ hybridization (FI...
BACKGROUND Transitional cell carcinoma (TCC) is the most predominant type of urinary bladder tumor. As cyclooxygenase (COX)-2 is recently introduced as an attractive target molecule in bladder TCC, we evaluated the immunohistochemical expression of this marker and its association with several clinicopathological characteristics. MATERIALS AND METHODS This cross-sectional study was performed i...
OBJECTIVE The aim of our study was to determine whether there is an increased incidence of urothelial cancer, especially transitional cell carcinoma (TCC), in uremic patients on dialysis. METHODS Retrospective chart analyses were completed for 1,910 uremic patients undergoing maintenance dialysis between January 1987 and December 1997. The incidence of urinary tract cancer was assessed. Only ...
Transitional cell carcinoma(T.C.C) of bladder display an upredictable biological behavior.Morphologic methods of grading this tumor are insuficient to predict the clinical outcome of the patients.the aim of this study was to investigate the relationships between histological grading staging and DAN ploidy especially in intermediate grade II(IIa and IIb). in a retrospective study of tissue spec...
micropapillary variant of urothelial carcinoma (uc) of the bladder is an aggressive tumour, comprising 0.6-6% of all uc. it generally presents with high-grade and stage, and has been reported as having a worse prognosis when compared to traditional uc. we report the case of a 58-year-old man who presented with macroscopic haematuria. the patient was diagnosed with high-grade urothelial carcinom...
16 Transitional cell carcinoma (TCC), the most common cancer of the urinary bladder in 17 dogs, is usually diagnosed at an advanced disease stage with limited response to chemotherapy. 18 Commercial screening tests lack specificity and current diagnostic procedures are invasive. A 19 proof of concept pilot project for analyzing the canine urinary proteome as a non-invasive 20 diagnostic tool fo...
