The importance of the optimal volume in the treatment of locally recurrent nasopharyngeal carcinoma; brachytherapy or stereotactic radiotherapy?
Introduction: Nasopharyngeal carcinoma (NPC) is commonly known as a radiosensitive tumor with the initial good response to radiation. Despite the improved outcome in loco regional control by the introduction of combining treatment, modern radiotherapy techniques and enhanced imaging studies, local recurrent after primary treatment with rate ranges from 15-58% in 5 years, stil...
متن کاملRad51 Expression in Nasopharyngeal Carcinoma and Its Association with Tumor Reduction: A Preliminary Study in Indonesia
Background: Overexpression of Rad51 protein in many tumor cells has been proven to increase radioresistance and can be related to the resistance of chemosensitivity of tumor cells. This preliminary study was conducted to determine the relationship between the Rad51 expression level in nasopharyngeal carcinoma and the response of the treatment based on the measurement o...
متن کاملThe Effect Of P53 Protein Over-Expression And Its Clinical Features On The Response To Preoperative Chemoradiotherapy Of Esophageal Squamous Cell Carcinoma
Background and Objective: P53 is a suppressive gene that plays a key role in DNA repair and apoptosis. The purpose of this study was to investigate the effect of P53 protein over-expression and some clinicopathological factors on the esophageal squamous cell carcinoma (SCC) response to neoadjuvant chemoradiotherapy. Patients and Methods: In this retrospective cohort study, 44 patients with loc...
متن کاملA retrospective study of the prognostic value of MRI-derived residual tumors at the end of intensity-modulated radiotherapy in 358 patients with locally-advanced nasopharyngeal carcinoma
OBJECTIVE To retrospectively analyze the prognostic value of magnetic resonance imaging (MRI)-derived residual tumors after intensity-modulated radiation therapy (IMRT) in the patients with locally-advanced nasopharyngeal carcinoma. METHODS A total of 358 patients with locally-advanced nasopharyngeal carcinoma who received IMRT were classified as having residual tumors or no residual tumor ba...
متن کاملEvaluation of Cyclin D1 Expression in Esophageal Squamous Cell Carcinoma and its Effect on Response Rate to Neo- adjuvant Chemoradiotherapy
Background and Objective: Esophageal cancer especially squamous cell carcinoma (SCC) is one of the most common gastro intestinal malignancies in north part of Iran (Khorasan). The standard treatment for esophageal cancer is surgical resection, but its outcome remains poor. Then, the oncologists try to treat this cancer with sandwich protocols especially neo-adjuvant chemo-radiotherapy. Sever...
