Introduction: Bladder cancer is a new tissue formation most often of urothelial origin with potential for local, locoregional and distant invasion. Among its risk factors, urinary bilharzia endemic in our study area. The aim was to present the epidemiological, clinical histopathological aspects bladder department. Patients method: This descriptive cross-sectional over 12-month period from Janua...

background: the most frequently mutated tumor suppressor gene found in human cancer is p53. in a normal situation, p53 is activated upon the induction of dna damage to either arrest the cell cycle or to induce apoptosis. however, when mutated, p53 is no longer able to properly accomplish these functions. the aim of this study was to investigate the expression of p53 gene in cases of skin cancer...

Background The oral squamous cell carcinoma (OSCC) is a malignant neoplasm originating from the epithelial lining of the oral cavity, accounting for about 95% of malignant lesions in this region. In Brazil, the oral cavity is the fifth location of the highest incidence of cancer in men and the seventh in women. In 2012, Brazil was estimated at 9,990 new cases of oral cancer in men and 4,180 in ...

An estimated 36.38% of oral cancer cases in Colombia are lethal. Most cases are diagnosed in late stages, so early detection and control of risk factors would be the most effective tools for prevention. The aim of this study was to use a questionnaire to evaluate knowledge and practices regarding oral cancer among a group of dentists in southern Colombia. A sample of 93 dentists was asked to re...

Recent incidence data from the United States indicate that transitional cell carcinoma accounts for the vast majority (95%) of bladder tumors in this country, with squamous cell carcinoma (less than 3%) and adenocarcinoma (less than 2%) comprising nearly all the remaining cases. Rates of squamous cell carcinoma and adenocarcinoma were higher in blacks compared to whites, while the reverse was t...

Changes in Salivary Antioxidants Patients with Oral Squamous Cell Carcinoma: Systematic Review Study and Meta-Analysis

Background Podoplanin is a type I transmembrane sialomucin-like glycoprotein that is specifically expressed in lymphatic endothelial cells. Studies have shown that assessment of podoplanin expression in the epithelial cells can be used to predict the malignant transformation of potentially malignant disorders and the metastatic tendency of primary head and neck squamous cell carcinoma. The aim ...

BACKGROUND To investigate the related risk factors of postoperative nosocomial pneumonia (POP) in patients with I-IIIa lung cancer. METHODS Medical records of 511 patients who underwent resection for lung cancer between January 2012 to December 2012 were retrospectively reviewed. Risk factors of postoperative pneumonia were identified and evaluated by univariate and multivariate analyses. R...

The presence of lymph node metastasis is the most important prognostic factor in oral cancer. The purpose of this study was to find useful markers for predicting occult cervical lymph node metastasis in patients with stage I or II squamous cell carcinoma of the oral cavity. We investigated 6 clinicopathologic factors and 2 genetic markers to predict late or occult cervical metastasis in 33 pati...
