histological grading is a good parameter to stratify tumors according to their biological aggressiveness. the elston and ellis grading method in humans, invasive ductal breast carcinomas and other invasive tumors are routinely used. the aims of this study were classification of mammary gland tumors and also application of a human grading method in canine mammary carcinoma. the samples included ...
background diffusion-weighted imaging (dwi) is a form of magnetic resonance imaging (mri) based on measuring the random brownian motion of water molecules within the biological tissues and is particularly useful in tumor characterization. objectives the purpose of this study was to evaluate the diagnostic value of dw mri and the apparent diffusion coefficient (adc) for preoperative grading of a...
Introduction: Glioma is the most common type of brain malignancy among adults. Treatment for this type of tumor involves surgery, radiotherapy, and in higher grades, including chemotherapy. The precise grading of the tumor is critical for treatment planning and prognosis determining. Considering the possibility of problems such as errors in tissue sampling during surgery, as we...

Introduction: The most common primary tumors of brain are gliomas and tumor grading is essential for designing proper treatment strategies. The gold standard choice to determine grade of glial tumor is biopsy which is an invasive method. The purpose of this study was to investigatethe role of fiber density index (FDi) by means of diffusion tensor imaging (DTI) (as a noninvasive method) in glial...
Background & Aim: Breast carcinoma is the most common malignant tumor and the leading cause of death from carcinoma in women. Tumor grading is important as a prognostic factor in the treatment of patients and is routinely done on histologic specimens. Although breast cytology is a proven diagnostic technique in clinical practice, its use is frequently limited to establishing the benign or m...
Background: Given that ovarian cancer symptoms are nonspecific and that appropriate surgical staging and pathological grading are important for the best treatment and prognosis of patients, this study aimed to determine the correlation of preoperative serum levels of CA125 and He4 with staging and grading. Materials and Methods: This cross-sectional study recruited 29 patients with epithelial...
Background and Objective: Evaluation of tumor proliferative activity may provide a predicting parameter to estimate biologic aggression and a subsequent prognosis that has been evaluated in many malignancies. We have selected renal cell carcinoma (RCC) in this study. To determine tumor proliferative activity, KI67 antibody was applied and results were compared with apoptosis, applying P53 antib...
