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 کاملEarly clinical experience of radiotherapy of prostate cancer with volumetric modulated arc therapy
BACKGROUND To report about initial clinical experience in radiation treatment of carcinoma of prostate with volumetric modulated arcs with the RapidArc (RA) technology. METHODS Forty-five patients with a median age of 72 +/- 3, affected by prostate carcinoma (T1c: 22 patients, T2a-b: 17 patients, T3a-b: 6 patients. N0: 43 patients, N1-Nx: 2 patients, all M0), with initial PSA of 10.0 +/- 3.0 ...
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...
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 کاملMulti‐isocentric 4π volumetric‐modulated arc therapy approach for head and neck cancer
OBJECTIVES To explore the feasibility of multi-isocentric 4π volumetric-modulated arc therapy (MI4π-VMAT) for the complex targets of head and neck cancers. METHODS Twenty-five previously treated patients of HNC underwent re-planning to improve the dose distributions with either coplanar VMAT technique (CP-VMAT) or noncoplanar MI4π-VMAT plans. The latter, involving 3-6 noncoplanar arcs and 2-3...
