Objective: To analyze and compare clinico-pathologic characteristics and survival between lung tumors with mixed histologic pattern and our population of resected lung tumors with single histology in the same period. Methods: From January 1993 to December 1999, 1158 patients received resection for lung tumors. Of these, 59 (5.1%) presented a mixed histologic pattern on the surgical specimen. Th...

BACKGROUND The prognostic significance of tumor size in gastric cancer is not well defined. The objective of this study was to identify the prognostic value of tumor size in patients with gastric cancer. METHODS We retrospectively reviewed a total of 1800 patients with gastric cancer admitted to our hospital between 1997 and 2007. These patients were divided into two groups according to tumor...

The aim of the study was to correlate the DNA Index (DI) and S-phase fraction (SPF) values determined by multiparametric flow cytometry in breast cancer (mainly T1 and T2 stages) with several clinico-pathologic variables and other biological parameters. For this purpose, a total of 136 breast cancers were submitted to flow cytometry and to several types of immunohistochemical analyses. Among cl...

BACKGROUND Claudin and occludin are the important tight junctions protein in human. The downregulation or upregulation of claudins and occludin might have a role in cancer development. The objective of this study was to investigate the expression of claudin-5, claudin-7 and occludin in oral squamous cell carcinoma (OSCC) and their relationships with the prognostically-related clinico-pathologic...

purpose: to report the clinico-pathological and ultrastructural features of a case of meesmann corneal dystrophy (mcd). case report: a 10-year-old boy presented with decreased vision in both eyes since early childhood. slitlamp biomicroscopy disclosed diffuse intraepithelial microcystic changes in the cornea but other layers appeared unremarkable. high pathologic myopia and amblyopia were other...

BACKGROUND AND OBJECTIVE The diagnostic and prognostic value of bone marrow biopsy (BMB) has been widely investigated in patients with chronic myeloproliferative disorders (CMPD). The present study is based on a review of the results of routine BMBs taken from 93 essential thrombocythemia (ET) patients at the time of diagnosis. DESIGN AND METHODS The common BMB histologic parameters and clini...

BACKGROUND Prognostication of breast cancer using clinico-pathologic variables, although useful, remains imperfect. Recent research has focused on finding new markers of prognosis using gene expression profiling. Panels of proteins assessed by immunohistochemistry might also be useful in this regard. This study focused on Bcl-2 protein expression in triple-negative (TNBC) and non- triple-negati...
