OBJECTIVES/HYPOTHESIS To examine if macroscopic classification with a magnifying gastrointestinal endoscope with narrow band imaging (ME-NBI) is useful in predicting pathological depth of tumor invasion in laryngo-pharyngeal cancer. STUDY DESIGN Retrospective study. METHODS Preoperative endoscopy reports and postoperative pathological reports on 139 laryngo-pharyngeal cancer lesions were re...

Introduction: To enhance the dose to tumor, the use of high atomic number elements has been proposed. Objective: The aim of this study is to investigate the effect of gold nanoparticle distribution on dose enhancement in tumor when the tumor is irradiated by typical monoenergetic X-ray beams by considering homogeneous and inhomogeneous distributions of gold nanoparticles (GNPs)...

Background and Objectives: Involvement of lymph nodes is an important prognostic factor in the most cancers, including colorectal cancer. In the recent years, invasion to blood and lymphatic vessels has been shown to predict involvement of lymph nodes and the number of involved nodes has been less studied issue. The aim of this study was determination of the relationship between the size of col...

Cancer is a class of diseases characterized by out-of-control cells' growth which affect cells and make them damaged. Many treatment options for cancer exist. Chemotherapy as an important treatment option is the use of drugs to treat cancer. The anticancer drug travels to the tumor and then diffuses in it through capillaries. The diffusion of drugs in the solid tumor is limited by penetration d...

BACKGROUND The purpose of this study was to compare the change in depth of target volume and dosimetric parameters between the supine and lateral decubitus positions for breast boost treatment with electron beam therapy. METHODS We analyzed 45 patients who were treated, between 2009-2010, with whole breast radiation (WBRT) followed by a tumor bed boost in the lateral decubitius position. Tumo...

Breslow tumor thickness is a major prognostic factor for melanoma. As it based on histopathological evaluation, not available to aid clinical decision making at the time of melanoma diagnosis. In this work, we assessed efficacy multispectral imaging (MSI) predict and developed classification algorithm determine optimal surgical safety margins. First, excluded nevi from analysis with use novel q...
