AIM: For simultaneous bilateral breast cancer (SBBC) treatment, conventional radiotherapy (RT) has a number of critical shortcomings. Thus, the usefulness of volumetric arc therapy (VMAT) for SBBC is undeniable. CASE REPORT: A 34-year-old woman with SBBC received neoadjuvant chemotherapy followed by breast-conserving surgery and bilateral lymph node dissection. Given the conservative surgery and the nodal involvement after neoadjuvant chemotherapy, bilateral adjuvant RT to the breasts and regional nodes with doses of 50 Gy in 25 fractions and a simultaneous integrated boost (SIB) of 60 Gy to the surgical bed was proposed...

BACKGROUND: Accelerated partial breast irradiation (APBI) is an option for adjuvant radiotherapy according to ASTRO and ESTRO recommendations. Among the available techniques, volumetric-modulated arc therapy (VMAT) is attractive but has not been extensively studied for APBI. This study assessed its feasibility, tolerance and early oncological outcomes. METHODS: We analysed the data of nine patients (median age 74 years) with ten lesions (one bilateral cancer) treated from May 2011 to July 2012 with APBI using VMAT...

PURPOSE: Breast cancer patients with bilateral implant reconstructions who require postmastectomy radiotherapy can pose unique treatment planning challenges. The use of VMAT may provide advantages over conventional tangent or multi-beam IMRT techniques. Moreover, daily setup uncertainly of the arm position, however, could have significant impact on accurate dose delivery. This study compares the plan qualities between non-AA and AA VMAT techniques. METHODS: Three breast cancer patients receiving left chest wall and regional nodal irradiation with bilateral implant reconstructions were studied...

PURPOSE: The purpose of this study was to evaluate the risks of second cancers and cardiovascular diseases associated with an optimized volumetric modulated arc therapy (VMAT) planning solution in a selected cohort of stage I/II Hodgkin lymphoma (HL) patients treated with either involved-node or involved-site radiation therapy in comparison with 3-dimensional conformal radiation therapy (3D-CRT). METHODS AND MATERIALS: Thirty-eight patients (13 males and 25 females) were included...

The purpose of this study was to assess the feasibility of using a multiple partial volumetric-modulated arcs therapy (MP-VMAT) technique on the left breast irradiation and to evaluate the dosimetry and treatment efficiency. Ten patients with left-sided breast cancer who had been treated by whole breast irradiation were selected for the treatment plan evaluation by using six partial volumetric modulated arcs. Each arc consisted of a 50° gantry rotation. The planning target volumes and the normal organs, including the right breast, the bilateral lungs, left ventricle, heart, and unspecified tissue, were contoured on the CT images...

BACKGROUND: To report results in terms of feasibility and early toxicity of hypofractionated simultaneous integrated boost (SIB) approach with Volumetric Modulated Arc Therapy (VMAT) as adjuvant treatment after breast-conserving surgery. METHODS: Between September 2010 and May 2011, 50 consecutive patients presenting early-stage breast cancer were submitted to adjuvant radiotherapy with SIB-VMAT approach using RapidArc in our Institution (Istituto Clinico Humanitas ICH)...
