Background. Our aim was to correlate patterns of failure with target volume delineations in patients with head and neck squamous cell carcinoma (HNSCC) treated with intensitymodulated radiation therapy (IMRT) and to report subjective xerostomia outcomes after IMRT as compared with conventional radiation therapy (CRT). Methods. Between January 2000 and April 2005, 69 patients with newly diagnose...

BACKGROUND Presenting the initial clinical results in the treatment of complex shaped adenoid cystic carcinomas (ACC) of the head and neck region by inverse planned stereotactic IMRT. MATERIALS 25 patients with huge ACC in different areas of the head and neck were treated. At the time of radiotherapy two patients already suffered from distant metastases. A complete resection of the tumor was ...

background: footwear with a curved “rollover” sole is prescribed to improve walking capability. shoes with a curved sole profile have been reported to alter ankle, knee and hip kinematics and posture and thought to able to modify head and neck, and trunk posture. therefore, the aim of this study was to investigate the immediate effects of rollover footwear on standing posture of head and neck, ...

The reproducibility of patient setup is an important issue for head and neck cancers treated with intensity-modulated radiation therapy (IMRT). In this study, an image-guided radiation therapy (IGRT) system has been used to minimize the uncertainty of patient setup while standard thermoplastic masks were used to provide adequate immobilization for the head and neck. However, they do not provide...

BACKGROUND This retrospective study evaluates efficacy and tolerability of high-dose hypofractionated radiotherapy (RT) in patients with head and neck cancer. METHODS All patients with head and neck cancer treated between September 2003 and September 2013 with 12 × 4 Gy RT were included. Two and 3D-RT or intensity-modulated radiotherapy (IMRT) were used. Overall survival (OS), tumor response,...

PURPOSE Volumetric modulated arc therapy (VMAT) is a specific type of intensity-modulated radiation therapy (IMRT) in which the gantry speed, multileaf collimator (MLC) leaf position, and dose rate vary continuously during delivery. A treatment planning system for VMAT is presented. METHODS Arc control points are created uniformly throughout one or more arcs. An iterative least-squares algori...
