background: colorectal adenocarcinoma is one of the most prevalent and treatable malignancies of the gastrointestinal tract. pattern of expression of the p53, p21, p16, e-cadherin and |î²|-catenin proteins are shown to be related to the prognosis of this malignancy. we aimed to compare the pattern of expression of these proteins in tumoral and nontumoral mucosal cells of cancer and on-cancer pa...
We present an overview of the history, development, technological advancements, current application, and future trends of cranial endoscopy. Neuroendoscopy provides a safe and effective management modality for the treatment of a variety of intracranial disorders, either tumoral or non-tumoral, congenital, developmental, and degenerative, and its knowledge, indications, and limits are fundamenta...
Peripheral T-cell lymphomas (PTCLs) are aggressive tumors in which the current therapy based on multiagent chemotherapy is not successful. Since cytochrome P450 3A subfamily (CYP3A) enzymes are involved in the inactivation of chemotherapy drugs, we hypothesized that CYP3A and P-glycoprotein (MDR1) expression in these lymphomas could result in a poor clinical response. We measured tumoral CYP3A ...
objective: to evaluate the mrna expression ratio of bcl-2/bax both in normal and tumoral bladder tissues of patients with transitional cell carcinoma (tcc) of bladder and investigate potential correlation between this expression ratio and clinical outcome. materials and methods: in this experimental study, we used real time-pcr to investigate the expression of bcl-2 and bax both in normal and t...
PURPOSE To determine how often loss of ataxia-telangiectasia-mutated (ATM) protein expression occurs in primary pancreatic ductal adenocarcinomas and to determine its prognostic significance. EXPERIMENTAL DESIGN The expression of ATM and TP53 was determined by immunohistochemistry in 397 surgically resected pancreatic ductal adenocarcinomas (Hopkins; Johns Hopkins Medical Institutions, Baltim...
OBJECTIVE In recent studies focusing on the prognostic significance of histologic features of NSCLC tumors, vessel invasion was correlated to survival across all surgical stages. We similarly analyzed whether intra-tumoral permeation could affect survival in subgroups of stage I and II NSCLC. METHODS A retrospective single institution analysis of a prospectively computed database. Specimens w...
