title: Interest in cavity shaving in breast conservative treatment does not depend on lumpectomy technique.
abstract: In breast conserving surgery (BCS), the usefulness to perform systematic cavity shaving is actively debated. Some investigators argued that systematic cavity shaving could avoid surgical re-excision and make diagnosis of unexpected multifocality. Others argued that usefulness of cavity shaving depends on volumes of resection. In this study one hundred patients undergoing BCS with systematic cavity shaving were included. Margins less than 3 mm were considered to be insufficient. We tested clinico-pathological characteristics in order to identify predictive model of cavity margin shaving utility and we sought to determine if cavity margin shaving usefulness depends on volumes of resection. We showed that cavity shaving avoids the need for re-excision in 24% of cases as well as diagnosis of multifocality in 6% of cases. However, the clinical usefulness of cavity shaving was not related to the volumes of resection.
