Background: Bladder cancer accounts for about 7% of all cancers among adults in Iran. We aimed to evaluate epidemiological and clinicopathological features of bladder cancer in Kermanshah province, west Iran. Methods: In a descriptive retrospective study, records of patients with bladder cancer referring to Imam Reza Hospital, Kermanshah city, Iran during 2011-2013 were analyzed. Sex, age, smo...

A modified Gleason grading system as proposed in the 2005 International Society of Urological Pathology (ISUP) consensus meeting is the current grading system for prostate cancer. With this modified ISUP Gleason grading system, many Gleason score (GS) 6 cancers by the old grading system are upgraded to GS7 cancers on biopsy diagnosis even with minimal quantity (≤5%) of Gleason pattern 4 (GP4) c...

PURPOSE We evaluated the rim patterns of intracranial meningiomas on nonenhanced (NE) and contrast-enhanced (CE) 3-dimensional fluid-attenuated inversion recovery (3D FLAIR) imaging on 3-tesla magnetic resonance (MR) imaging to clarify the associated imaging and pathological findings and the value of the rims in predicting tumor cleavability. METHODS Thirty-two patients with meningioma underw...

BACKGROUND Oral cancer is revisited on a pathologist perspective with advanced imaging technique. OBJECTIVE The present study assessed the new malignancy grading system at tumor proper (TP) and Bryne's grading system at invasive tumor front (ITF), morphometric features using software, to clarify their associations with prognosis of oral cancers. METHODS Histologically confirmed oral squamou...

Introdouction: Mucoepidermoid carcinoma (MEC) is one of the most common salivary gland malignancies. The prevalence of salivary gland tumors varies in different geographic areas. In this report, we evaluated the prevalence of MEC in Iran and compared it with that previously reported in other countries. Materials and methods: The files of oral pathology, Shahid Beheshti University of Medical ...

intra-operative management of thyroid gland in laryngeal cancer is controversial. to determine the rate of thyroid involvement in patients with laryngeal cancer treated by radical surgical excision, we reviewed the records during 1996-2000 in imam khomeini hospital, cancer institute, and amir alam hospital.we studied several factors such as age, gender, and tumor location, presence of thyroid i...

Quantification of protein expression in tissue sections stained by immunohistochemistry has traditionally involved visual grading techniques. However, if these results are to be used to predict tumor behavior and permit targeted therapy, there is a need for more accurate, objective, and reproducible methods. This study investigated the utility of spectral imaging as a method of quantifying thym...

OBJECTIVE To investigate the relationship between the expression level of matrix-metalloproteinases (MMPs) with the pathological grades and MRI characteristics of human gliomas. METHODS Prior pre- and post-contrast enhancement MRI was performed on 31 patients with gliomas, which were confirmed by post-operational pathology. The expression of MMP-2 and MMP-9 were determined by immunohistochemi...
