The dosimetric impact of seroma volume changes over the course of radiotherapy treatment on sequential boost planning (Arm I) and a comparison of two concurrent hypofractionated boost methods (Arm II) for breast cancer patients eligible for RTOG protocol

چکیده
Breast conserving surgery with adjuvant radiation therapy is supported by mult iple clinical t rials as being a safe alternative to total mastectomy. 2 Outlined by Arm I of RTOG Protocol 1005, 1 one current standard of care for external beam radiation (EBRT) is delivery of 50 Gray (Gy) in 25 fract ions to the whole breast with a sequential 12 Gy photon or electron boost to the post-lumpectomy bed delivered in 6 fractions. The addition of such a tumor bed boost has shown to further decrease recurrence rates for patients with invasive breast cancer. 3

Dosimetric Evaluation of Target Volume in Breast Boost Radiotherapy: Comparison of Electron and Photon Beam
Background and purpose: Breast‑conserving surgery followed by radiation therapy to the whole breast is now recognized as a standard strategy in patients with breast cancer. Recommended technique for radiotherapy is whole breast irradiation followed by boost to the tumor bed. This study aimed to compare the dosimetric parameters of electron and photon beams for boosting irradiation in post‑lump...
متن کاملComparison of two radiation techniques in breast boost delivery
Introduction: In the treatment of breast cancer, breast conserving surgery (BCS) and whole breast irradiation is a usual technique. The influence of lumpectomy boost following breast radiotherapy is apparent, but there are different delivery methods. This work intended to compare the dosimetric parameters of electron beams and photon beams for boosting irradiation in breast can...
متن کاملAcute Skin and Pharynx Complications Following Adjuvant Hypofractionated Versus Conventional Radiotherapy in Patients with Breast Cancer
Background: Hypofractionated radiotherapy (HF) method was introduced to overcome the quickly growing tumor cells as well as shortening whole treatment course in solid tumors such as breast cancers. Here, we compared the incidence of dermatitis and pharyngitis among patients undergoing HF versus conventional fractionationated (CF) radiation therapy following surgery for breast cancer. Methods: ...

Background: The aim of this study was to compare the differences of the dosimetric parameters between three-dimensional conformal radiotherapy (3D-CRT) and simultaneous-integrated boost intensity-modulated radiotherapy (SIB-IMRT) techniques in the prone and supine positions for breast irradiation. Materials and Methods: Ten patients underwent a computed tomography simulation in both the prone a...
متن کاملDosimetric Comparison of 3D Tangential Radiotherapy of Post-Lumpectomy Breast at Two Different Energies
Introduction: Radiation therapy following breast conserving surgery is one of the most common procedures performed in any radiation oncology department. A tangential parallel-opposed pair is almost always the technique of choice for this purpose. This technique is often performed based on 3D treatment planning. The aim of this study was to compare 3D treatment planning for two different energie...
