Dosimetric comparisons of VMAT, IMRT and 3DCRT for locally advanced rectal cancer with simultaneous integrated boost
PURPOSE The purpose of this study is to compare the dosimetric differences among volumetric modulated arc therapy (VMAT), fixed-field intensity modulated radiotherapy (IMRT) and three-dimensional conformal radiotherapy (3D-CRT) for the preoperative locally advanced rectal cancer (LARC). METHODS Ten LARC patients treated in our department using the simultaneous escalate strategy were retrospec...
متن کاملA comparative dosimetric study of left sided breast cancer after breast-conserving surgery treated with VMAT and IMRT.
BACKGROUND AND PURPOSES This study compared VMAT and IMRT plans for intact breast radiotherapy for left sided breast cancer and evaluated the irradiated dose of planning target volume and OARs, especially focusing on heart and coronary artery. MATERIALS AND METHODS Eleven patients with left sided breast cancer whose breast was relatively smaller (the mean volumes is 296 cc) treated with breas...
متن کاملDosimetric comparison of preoperative single‐fraction partial breast radiotherapy techniques: 3D CRT, noncoplanar IMRT, coplanar IMRT, and VMAT
The purpose of this study was to compare dosimetric parameters of treatment plans among four techniques for preoperative single-fraction partial breast radiotherapy in order to select an optimal treatment technique. The techniques evaluated were noncoplanar 3D conformal radiation therapy (3D CRT), noncoplanar intensity-modulated radiation therapy (IMRTNC), coplanar IMRT (IMRTCO), and volumetric...
متن کاملResponse to the comments on “The Feasibility Study of a Hybrid Coplanar Arc Technique versus Hybrid Intensity-modulated Radiotherapy in Treatment of Early-stage Left-sided Breast Cancer with Simultaneous-integrated Boost. J Med Phys 2017;42:1-8”
Journal of Medical Physics ¦ Volume 42 ¦ Issue 2 ¦ April-June 2017 100 We highly appreciate your comments. It is well known that there are considerable target position uncertainties during breast radiotherapy. These uncertainties result from respiratory motions, tissue and organ deformation, daily patient setup, and other causes. Respiratory gating and breath control can reduce the target posit...
متن کاملDosimetric Evaluation of Volumetric Modulated Arc Therapy (VMAT) and Intensity Modulated Radiotherapy (IMRT) Using AAPM TG 119 Protocol
Background: The commissioning accuracy of Volumetric Modulated Arc Therapy (VMAT) need to be evaluated.Objective: To test and evaluate commissioning accuracy of VMAT based on the TG 119 protocols at local institution. Material and Methods: The phantom, structure sets, VMAT and IMRT beam parameter setup, dose prescriptions and planning objectives were following TG 119 guidelines to c...
