Oncoplastic breast surgery – a pictorial classification system for surgeons and radiation oncologists (OPSURGE)

Abstract

AbstractIntroductionChanges to the tumour bed following oncoplastic breast surgery complicate the administration of adjuvant radiotherapy. Consensus guidelines have called for improved interdisciplinary communication to aid adjuvant boost radiotherapy. We propose a framework of tumour bed classification following oncoplastic surgery to enhance understanding and communication between the multidisciplinary breast cancer team and facilitate effective and more precise delivery of adjuvant boost radiotherapy.MethodsA classification system was devised by grouping oncoplastic procedures based on skin incision, tissue mobilization, tumour bed distortion, seroma formation and flap reconstruction. The system is supplemented by a colour‐coded pictorial guide to tumour bed rearrangement with common oncoplastic procedures.ResultsA 5‐tier framework was developed. Representative images were produced to describe tumour bed alterations.ConclusionThe proposed framework (OPSURGE) improves the identification of the primary tumour bed after initial breast‐conserving surgery, which is imperative to both the surgeon in planning re‐excision and the radiation oncologist in planning boost radiotherapy.
