Whole 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...
متن کاملFeasibility study of individualized optimal positioning selection for left‐sided whole breast radiotherapy: DIBH or prone
The deep inspiration breath hold (DIBH) and prone (P) position are two common heart-sparing techniques for external-beam radiation treatment of left-sided breast cancer patients. Clinicians select the position that is deemed to be better for tissue sparing based on their experience. This approach, however, is not always optimum and consistent. In response to this, we develop a quantitative tool...
متن کاملReproducibility of deep inspiration breath hold for prone left-sided whole breast irradiation
BACKGROUND Investigating reproducibility and instability of deep inspiration breath hold (DIBH) in the prone position to reduce heart dose for left-sided whole breast irradiation. METHODS Thirty patients were included and underwent 2 prone DIBH CT-scans during simulation. Overlap indices were calculated for the ipsilateral breast, heart and lungs to evaluate the anatomical reproducibility of ...
متن کاملChanges in breast radiotherapy: prone positioning and hypofractionation.
Breast cancer management has drastically changed since the 1990s. Many patients with breast cancer now can opt to conserve their breast through a lumpectomy and radiation (breast conservation therapy), rather than a full mastectomy. Advances in the techniques of delivery and length of breast radiotherapy have been rapidly evolving. This article attempts to summarize some of those changes for nu...
متن کاملThree-dimensional conformal breast irradiation in the prone position.
The prone position can be used for the planning of adjuvant radiotherapy after conservative breast surgery in order to deliver less irradiation to lung and cardiac tissue. In the present study, we compared the results of three-dimensional conformal radiotherapy planning for five patients irradiated in the supine and prone position. Tumor stage was T1N0M0 in four patients and T1N1M0 in one. All ...
