Background: The most common primary tumors of brain are gliomas. Grading of tumor is vital for designing proper treatment plans. The gold standard choice to determine the grade of glial tumor is biopsy which is an invasive method.Objective: In this study, we try to investigate the role of fractional anisotropy (diffusion anisotropy) and linear anisotropy ...

Background: Ovarian carcinoma is one of the leading causes of cancer-related death among females. K-ras codon 12 mutations are commonly occurring mutations in different types of cancers and leads to resistance against anti-EGFR therapeutics. Hence, determination of mutations in k-ras gene is crucial for predicting response to anti-EGFR therapies. This study aimed to evaluate the prevalence of k...

Background & Objective: Gliomas are the most common type of primary intracranial tumors in adults. The expression of estrogen receptors varies in different grades of glial tumors, and some studies have suggested that this expression might have a prognostic value. It seems that estrogen receptor expression negatively correlates with the histological grade of gliomas. In the pres...

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 sci...

BACKGROUND AND PURPOSE Diffusion tensor metrics are potential in vivo quantitative neuroimaging biomarkers for the characterization of brain tumor subtype. This meta-analysis analyzes the ability of mean diffusivity and fractional anisotropy to distinguish low-grade from high-grade gliomas in the identifiable tumor core and the region of peripheral edema. MATERIALS AND METHODS A meta-analysis...

BACKGROUND Heterogeneity of prostate carcinoma is one of the reasons for pretreatment underestimation of tumor aggressiveness. We studied tumor heterogeneity and the probability of finding the highest tumor grade and DNA aneuploidy with relation to the number of biopsies. MATERIAL AND METHODS Specimens simulating core biopsies from five randomly selected tumor areas from each of 16 Böcking's ...

Uterine sarcomas are rare female genital tract malignancies. Mullerian adenosarcoma is a biphasic malignant mesenchymal tumor comprising of benign glandular and (usually low grade) stromal component, both which integral neoplastic constituents the tumor.[1] This represents less than 8% uterine sarcomas. About 200 cases have been reported in literature so far [2] 22 case were from India. Adenosa...
