[Placement of metal clips as a means for identifying the @entity5 bed in XXXX post lumpectomy].

@entity1 @entity5 @entity343
INTRODUCTION: Surgical clips inserted during breast-conserving surgery [BCS] serve as a surrogate of the lumpectomy cavity. Visualization of the surgical clips by imaging prior to radiotherapy (RT), during treatment planning, aids in designing the treatment volume for breast irradiation. OBJECTIVES: The aim of this study was to evaluate whether there is a distinct difference in the tendency to insert a metal clip during BCS, that is related to the hospital where the procedure was performed and to evaluate whether there are differences in the boost planning treatment volume ( @entity343 ). METHODS: This is a retrospective study. The records of all @entity1 treated by adjuvant RT after BCS were reviewed. Boost @entity343 was calculated in cubic centimeters (ccj and compared between the groups. RESULTS: Of the 143 @entity1 included in the study, 31% were operated on in private hospitals and 69% were operated on in public hospitals. A statistically significant difference was found in clip insertion in @entity1 treated in private hospitals compared to public hospitals. No statistical differences were found in the boost @entity343 size between the groups (p = 0.448). A similar difference was found when comparing tertiary public centers to smaller secondary public centers. CONCLUSION: Our study demonstrates a higher tendency to insert metal clips during BCS in private hospitals as compared to public hospitals. There were no differences in the @entity5 bed @entity343 in @entity1 with or without surgical clips.
