Tumor volume is an independent prognostic indicator of local control in nasopharyngeal carcinoma patients treated with intensity-modulated radiotherapy
BACKGROUND To retrospectively analyze whether primary tumor volume and primary nodal volume could be considered independent prognostic factors for nasopharyngeal carcinoma treated with intensity-modulated radiation therapy. METHODS Three hundred sixty-three consecutive nasopharyngeal carcinoma (NPC) patients who were stage I-IVa+b and treated with intensity-modulated radiotherapy (IMRT) in ou...
متن کاملApplication of computed tomography and magnetic resonance imaging fusion images for delineating gross tumor volume in three-dimensional conformal radiotherapy of nasopharyngeal carcinoma
Background: To evaluate computed tomography (CT) and magnetic resonance imaging (MRI) fusion images for delineating gross tumor volume (GTV) in three-dimensional conformal radiotherapy (3D-CRT) of nasophanrygeal carcinoma (NPC), and compare treatment outcomes between CT- and CT+MRI-based targets. Materials and Methods: A total of 120 NPC patients treated with 3D-CRT were included, in which, 60 ...
متن کاملThe 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 کاملImpact of primary tumor volume on local control after definitive radiotherapy for head and neck cancer.
BACKGROUND The impact of primary tumor volume (pTV) on local control after definitive radiotherapy (RT) for head and neck squamous cell carcinoma (HNSCC) is unclear. METHODS Pertinent literature was reviewed to address the impact of pTV on local control after definitive RT for HNSCC. RESULTS Reproducibility of pTV calculations is probably influenced by interobserver variability and may be r...
متن کاملPrognostic Significance of Tumor Volume in Locally Recurrent Nasopharyngeal Carcinoma Treated with Salvage Intensity-Modulated Radiotherapy
INTRODUCTION To evaluate the prognostic value of gross tumor volume (TV) in patients with locally recurrent, nonmetastatic nasopharyngeal carcinoma. METHODS Between 2001 and 2012, 291 consecutive patients with locally recurrent, nonmetastatic nasopharyngeal carcinoma underwent salvage IMRT were retrospectively reviewed. The correlations between TV and recurrent T classification were analyzed....
