Abstract

|
The purpose of this study was to determine the clinical feasibility of multistatic fields technique (MSF) and to compare dosimetric factors with 3-dimensional conformal radiation therapy (3DCRT). Thirty breast cancer patients were randomly selected for comparison of MSF radiation treatment plan with 3DCRT. Both MSF planning and 3DCRT planning were performed employing the Plato planning system (Plato Sunrise V 26.4). The dosimetric data showed that improved dose homogeneity in the whole breast volume and reduction in the dose to ipsilateral lung and heart for MSF treatments, which may be of clinical value in potentially contributing to improved cosmetic results and reduced late treatment-related toxicity.
