Hypofractionated breast cancer radiotherapy. Helical tomotherapy in supine position or classic 3D-conformal radiotherapy in prone position: which is better?
We propose a comparative dosimetric study of whole-breast hypofractionated radiation therapy using helical tomotherapy (HT) in supine position and 3-D conformal radiotherapy (3D-CRT) in prone position. Twelve patients undergoing breast-conserving therapy were retrospectively selected from October to December 2012. Specific dose-volume parameters were selected for the study. The target coverage ...
متن کاملWhole breast and regional nodal irradiation in prone versus supine position in left sided breast cancer
BACKGROUND Prone whole breast irradiation (WBI) leads to reduced heart and lung doses in breast cancer patients receiving adjuvant radiotherapy. In this feasibility trial, we investigated the prone position for whole breast + lymph node irradiation (WB + LNI). METHODS A new support device was developed for optimal target coverage, on which patients are positioned in a position resembling a ph...

Introduction: This study compared the extubation of patients in prone versus supine positions in patients undergoing lumbar disc surgery. Methods: In this single-blind clinical trial, 60 patients who were candidates for elective lumbar disc surgery were selected and randomly assigned into two groups of 30 patients. All patients primarily underwent surgery in the prone position. After surgery a...
متن کاملWhole breast radiotherapy in prone and supine position: is there a place for multi-beam IMRT?
BACKGROUND Early stage breast cancer patients are long-term survivors and finding techniques that may lower acute and late radiotherapy-induced toxicity is crucial. We compared dosimetry of wedged tangential fields (W-TF), tangential field intensity-modulated radiotherapy (TF-IMRT) and multi-beam IMRT (MB-IMRT) in prone and supine positions for whole-breast irradiation (WBI). METHODS MB-IMRT,...
