Dosimetric comparison of treatment of left breast cancer using two different dose schedules Dosimetric comparison of treatment of left breast cancer using two different dose schedules
Background: To date, different kinds of treatment methods have been proposed for radiotherapy of cancer patients. Choosing the kind of treatment method affects the quality of the patient's treatment. This study aims to investigate the effect of the number of radiation treatment sessions on the dose received by the patient and the distribution of tumor dose and dose received by organs at risk in...
متن کاملFeasibility study of deep inspiration breath-hold based volumetric modulated arc therapy for locally advanced left sided breast cancer patients.
BACKGROUND The purpose of this study was to assess the feasibility of deep inspiration breath-hold (DIBH) based volumetric modulated arc therapy (VMAT) for locally advanced left sided breast cancer patients undergoing radical mastectomy. DIBH immobilizes the tumor bed providing dosimetric benefits over free breathing (FB). MATERIALS AND METHODS Ten left sided post mastectomy patients were imm...
متن کاملComparison of dosimetric radiotherapy of whole left- breast cancer using conventional tangential wedge-based techniques (CTT) and three intensity modulation techniques (IMRT)
Introduction: Whole breast radiotherapy after breast-conserving surgery decrease the risk of local recurrence. this study investigates the dosimetric aspects of intensity modulated radiotherapy (IMRT) compared to conventional tangential wedge-based beams techniques (CTT) of the whole breast in early stages breast cancer patients. Materials and Methods: Co...
متن کاملDosimetric comparison of whole breast radiotherapy using field in field and conformal radiotherapy techniques in early stage breast cancer
Background: We aimed to compare field-in-field technique (FIF) with conformal tangential field radiotherapy (CRT) in terms of dosimetric benefits for early stage breast cancer radiotherapy. Materials and Methods: Twenty consecutive left-side breast cancer patients who underwent breast-conserving surgery were included to the study. For each patient, two different treatment plans were cr...
متن کاملDosimetric and clinical advantages of deep inspiration breath-hold (DIBH) during radiotherapy of breast cancer
BACKGROUND To investigate the potential dosimetric and clinical benefits of Deep Inspiration Breath-Hold (DIBH) technique during radiotherapy of breast cancer compared with Free Breathing (FB). METHODS Eight left-sided breast cancer patients underwent a supervised breath hold during treatment. For each patient, two CT scans were acquired with and without breath hold, and virtual simulation wa...
