BLCA-4 is currently the most sensitive and specific urinary marker for bladder cancer. As the incidence of bladder cancer varies by ethnic and territory, we tended to evaluate the feasibility of bladder cancer detection using urinary BLCA-4 in Chinese Han nationality. Urines from 79 bladder cancer patients, 31 urinary tract infection patients and 29 normal controls were included. Tissue specime...

Cyclooxygenase (COX)-inhibiting drugs have antitumor activity in canine and rodent models of urinary bladder cancer. Two isoenzymes of COX have been identified, COX-1 and COX-2. The purpose of this study was to characterize COX-1 and COX-2 expression in human invasive transitional cell carcinoma of the urinary bladder by immunohistochemistry and Western blot analysis. COX-2 was not expressed in...

Improving the early detection rate and prediction of bladder cancer remains a great challenge in management of this disease. To examine the value of urinary orosomucoid 1 (ORM1) for the early detection and surveillance of bladder cancer, two-dimensional differential gel electrophoresis (2-DE) and matrix-assisted laser desorption time-of-flight mass spectrometry (MALDI-TOF/TOFMS) were applied to...

PURPOSE To study the role of urinary matrix metalloproteinase-1 (MMP-1) and tissue inhibitor of metalloproteinase-1 (TIMP-1) in bladder cancer and their relationship to tumor progression. EXPERIMENTAL DESIGN MMP-1 and TIMP-1 were measured by ELISA in urine samples from 131 patients with bladder tumors (7 cis, 74 Ta, 29 T1, and 21 T2-T4; 46 G(1), 41 G(2), and 37 G(3)), 5 patients with prostate...

The recurrence of bladder cancer after surgery with or without chemotherapy remains a major challenge in bladder cancer treatment. Previous studies have shown that transient receptor potential vanilloid 1 (TRPV1) acts as a tumor suppressor through inducing apoptosis in bladder cancer cells. However, whether activation of TRPV1 has any synergistic effects with pirarubicin (THP), one of main drug...

AIM To compare the results of bladder tumor associated antigen (BTA TRAK), nuclear matrix protein 22 (NMP 22) and voided urine cytology (VUC) in detecting bladder cancer. METHODS A total of 135 elderly male and 50 healthy volunteers enrolled in this study were classified into three groups: (i) 93 patients with bladder cancer; (ii) 42 patients with urinary benign conditions; and (iii) 50 healt...

background: this study compared the early success, complication and patient satisfaction rates of modified extraperitoneal radical cystectomy (mainz ii urinary diversion) with standard intraperitoneal radical cystectomy (continent ileocecal urinary diversion) in a group of patients with muscle invasive urothelial carcinoma of the urinary bladder. methods: from september 2009 until november 2013...

BACKGROUND New methods for detection of bladder cancer are needed because cystoscopy is both invasive and expensive and urine cytology has low sensitivity. We screened proteins as tumor markers for bladder cancer by proteomic analysis of cancerous and healthy tissues and investigated the diagnostic accuracy of one such marker in urine. METHODS Three specimens of bladder cancer and healthy uro...

An aging population and latent effects from exposure to carcinogens will likely augment the current trend of increased incidence of urinary bladder cancer. Intravesical antineoplastic therapy is a common treatment for urinary bladder cancer. Transurethral resection of bladder tumors often is followed immediately by the instillation of an antineoplastic agent in the operating room or postanesthe...

With multiple options for urinary diversion after radical cystectomy for bladder cancer that have comparable cancer control and complication rates, health-related quality of life (HRQOL) has become an important consideration. This article reviews the methods for defining HRQOL, the challenges in measuring HRQOL in bladder cancer, and the literature comparing HRQOL after various methods of urina...
