Early clinical experience with volumetric modulated arc therapy in head and neck cancer patients
BACKGROUND To report about early clinical experience in radiation treatment of head and neck cancer of different sites and histology by volumetric modulated arcs with the RapidArc technology. METHODS During 2009, 45 patients were treated at Istituto Clinico Humanitas with RapidArc (28 males and 17 females, median age 65 years). Of these, 78% received concomitant chemotherapy. Thirty-six patie...
متن کاملA Dosimetric Comparison of Double Arc Volumetric Modulated Arc Therapy with Large Field Intensity Modulated Radiation Therapy for Head and Neck Cancer
Background: This Study Evaluate two state of Art techniques, Rapid Arc and large-field sliding window IMRT in terms of dosimetric end points and delivery time for head and neck cancer. Materials and Methods: 22 patients with head and neck cancer were selected for a planning comparative study. All patients went to CT-simulation in supine position. PTVs were delineated for two dose level of presc...
متن کاملImplementation of volumetric arc therapy for head and neck cancer
In volumetric modulated arc therapy (VMAT), treatment is delivered using a continuous arc motion of the gantry with simultaneous variation of mlc position, gantry speed and dose rate. Several manufacturers offer VMAT facilities based on conventional accelerator gantries while others offer tomographic therapy based on ring gantries. A number of centres have begun clinical VMAT treatments in rece...
متن کاملIntensity modulated radiation therapy versus volumetric intensity modulated arc therapy
The advanced developments in external beam radiation therapy (EBRT) over the past few decades have improved dose conformity to the target while minimizing dose to the surrounding organs at risk (OAR). Intensity modulated radiation therapy (IMRT) and volumetric modulated arc therapy (VMAT) are two commonly used EBRT techniques to treat cancer. In sliding window (SW) or dynamic IMRT, each radiati...
متن کاملIntensity-modulated radiotherapy or volumetric-modulated arc therapy in patients with head and neck cancer: Focus on salivary glands dosimetry.
BACKGROUND Despite radiotherapy (RT) technical improvements, high salivary dysfunction rates are still reported in patients with head and neck squamous cell carcinoma (HNSCC). The purpose of the present study was to report salivary glands dosimetry with volumetric-modulated arc therapy (VMAT) and intensity-modulated RT (IMRT). METHODS Dosimetry of consecutive patients receiving IMRT or VMAT f...
