background: gliomas are the most common primary neoplasms of the central nervous system. relative cerebral blood volume (rcbv) could estimate high-grade gliomas computed with dynamic susceptibility contrast mr imaging which it is artificially lowered by contrast extravasation through a disrupted blood-brain barrier. objectives: our intent was to clarify the usefulness of diffusion-weighted magn...

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...

background: prostate cancer is the most common malignancy among the male population in the united states and the 3rd most common non-skin cancer among men in iran. its prevalence has shown a rising trend in recent decades. the aim of this study was to report the epidemiological features of prostate cancer in patients referred for prostate biopsy in the south of iran and to evaluate the accuracy...

Ependymoma constitute 5 % to 7 % of all primary CNS neoplasm. But their prevalence relative to other tumor type varies with patient age and presenting location. Ependymoma constitute approximately 1O % of intracranial neoplasm in pediatric population and up to 30 % of those encountered in children under 3 years of age. In spinal column, ependymoma constitute 60% of glial neoplasm, and opposed...

Background: Glidescope® video laryngoscope (GVL) is widely used in tracheal intubation. However, no studies have been conducted to compare the GVL and Macintosh direct laryngoscope (MDL) for intubation in patients with laryngeal neoplasm. Here, we aim to compare GVL and MDL for the intubation of laryngeal neoplasm patients. Methods: One hundred ninety-six American Society of Anesthesiology (ASA...

OBJECTIVE Phyllodes tumor of the prostate is a rare neoplasm. We report the clinical, histopathological, and immunohistochemical features of a low grade phyllodes tumor of the prostate with lung metastases. METHODS A 68-year-old man presented acute urinary obstruction. Suprapubic prostatectomy was performed, and one month later he developed acute urinary obstruction, shortness of breath and c...

Correspondence to: Daniela Radu:[email protected], M. Fernbach: [email protected], SUMMARY: Purpose: The present report was designed to evaluate how advanced colorectal neoplasm found at the moment of surgical treatment could represent a possible cause for high mortality rates. Main aim of this clinical study was to explore the current status of open surgery in the treatment of colorect...

Background and objective: Clear Cell Renal Cell Carcinoma (CCRCC) is the most common adult renal neoplasm. Staging and grading of RCC are important predictors of survival. Fuhrman nuclear grading is widely used for CCRCC, the subjective nature of which has prompted more objective methods to evaluate nuclear features. Furthermore, Ki-67, a reliable marker of cellular pr...

Background & Objective: Glioblastoma-multiforme is the high grade form of astrocytic tumors with a short survival time, which are the most common type of brain tumors. Therefore, finding new therapeutic options is essential. Cyclin D1 is expressed in some human malignancies and can be a potential target for therapeutic intervention. The aim of the present study was to determine...
