High-grade meningiomas are rare extra-axial tumors, frequently causing brain invasion and prominent brain edema. Patients harboring high-grade meningiomas occasionally present with behavior changes. Data about frequency and prognostic importance of preoperative behavior changes in patients with high-grade meningiomas is missing. 86 patients with primary high-grade meningiomas were analyzed. Sta...

BACKGROUND/AIM There are a lot of studies aiding to the opinion that the involvement degree of axilla lymph nodes grows depending on increase of breast tumor size, and its histological and nuclear grades. The aim of this study was to assess the risk of axillary lymph nodes involvement, as well as the relation between the tumor size, histological and nuclear grades in a group of female patients ...

introduction: breast cancer is the most common cause of cancer-related death among women. the aim of this study was to assess the pathologic findings of patients with breast cancer who were referred to the pathology ward in bandarabbas during 2002 to 2010. methods and materials: in this descriptive study in 2010, all patients with breast cancer who were referred to the pathology ward of bandara...

PURPOSE To assess the role of magnetic resonance imaging (MRI), particularly signal intensity changes, in predicting the dedifferentiation of parosteal osteosarcoma, and to evaluate other factors that may affect grading on MRI. MATERIALS AND METHODS MRI of 12 patients with parosteal osteosarcoma diagnosed on plain radiography were reviewed with regard to size, location, extent, soft tissue co...

BACKGROUND AND OBJECTIVES Gastric cancer is one of the most common cancers in the world. The aim of this study was to evaluate prognostic factors using Bayesian interval censoring analysis. METHODS This is a historical cohort study of 178 patients from February 2003 through January 2008, admitted with gastric cancer to one referral hospital in Tehran. Age at diagnosis, sex, histology type, tu...

PURPOSE The purpose of our study is to correlate quantitatively measured tumor stiffness with immunohistochemical (IHC) subtypes of breast cancer. Additionally, the influence of prognostic histologic features (cancer grade, size, lymph node status, and histological type and grade) to the tumor elasticity and IHC profile relationship will be investigated. METHODS Under an institutional review ...
