BACKGROUND Esophageal cancer in Iran is the sixth most common cancer and is particularly important in east Azerbaijan. The aim of this study was to calculate survival rates and define prognostic factors in esophageal cancer patients. METHODS In this study, all patients with esophageal cancer registered in the Radiation Therapy Center, during March 2006 to(More)
BACKGROUND Areas of Iran have among the highest incidences of esophageal cancer in the world. Definitive chemo-radiotherapy (DCRT) is used for locally advanced esophageal cancer and for inoperable tumors asan alternative to surgical treatment. MATERIALS AND METHODS This retrospective study was conducted in North- West Iran 2006-2011, including 267(More)
OBJECTIVES The aims of this study were to determine the effect of conjugated linoleic acid (CLA) supplementation on inflammatory factors and matrix metalloproteinase (MMP) enzymes in rectal cancer patients undergoing chemoradiothetrapy. METHOD AND MATERIAL In this randomized, double-blind, placebo-controlled pilot study, 34 volunteer patients with rectal(More)
Following failure of systemic chemotherapy, transarterial chemoembolization (TACE) is an available method to control unresectable liver metastases from colorectal carcinoma (CRC). The aim of present study was to evaluate the efficacy of chemoembolization for inoperable metastatic liver lesions from CRC. Forty-five CRC patients with liver metastases(More)
BACKGROUND Tumor length in patients with esophageal cancer (EC) has recently received great attention. However, its prognostic role for EC is controversial. The purpose of our study was to characterize the prognostic value of tumor length in EC patients and offer the optimum cut-off point of tumor length by reliable statistical methods. MATERIALS AND(More)
OBJECT The aim of this study was to demonstrate the feasibility of MR microimaging on a conventional 9.4 T horizontal animal MRI system using commercial available microcoils in combination with only minor modifications to the system, thereby opening this field to a larger community. MATERIALS AND METHODS Commercially available RF microcoils designed for(More)
INTRODUCTION Nanoparticles are promising as a new approach to enhance chemo- radiotherapy efficiency in breast cancer mainly via targeted therapy. MATERIALS & METHODS SKBR3 and T47D breast cancer cells were treated with superparamagnetic mesoporous hydroxyapatite nanocomposites (SPmHANs)conjugated with 1 μM doxorubicin and 0.5 mM 2-Deoxy-d-Glucose and(More)
BACKGROUND Arterial damage is sometimes associated with supracondylar fractures of the humerus. Diagnosis and careful management of the fracture and arterial repair is crucial. OBJECTIVES The aim of this study was to determine the prevalence and outcome of supracondylar fractures of the humerus with signs and symptoms of limb ischemia, before and after(More)
PURPOSE Breast cancer is the most common malignancy of women worldwide. Radiotherapy consists of a vital element in the treatment of breast cancer but relative side effects and different radioactive responses are limiting factors for a successful treatment. Doxorubicin has been used to treat cancers for over 30 years and is considered as the most effective(More)
Photoneutrons produced during radiation therapy with high energy photons is the main source of unwanted out-of-field received doses of patients. To analyze the neutron dose equivalent (NDE) for wedged beams and its variation with field size, Monte Carlo (MC) modeling of an 18MV photon beam was performed using MCNPX MC code. The results revealed that the NDE(More)
