Consensus statement on tumour bed localization for radiation after oncoplastic breast surgery

Area of Science:

• Oncology
• Surgical Oncology
• Radiation Oncology

Background:

• Oncoplastic surgery (OPS) is increasingly standard for breast conservation.
• Accurate tumor bed (TBD) delineation is challenging post-OPS, impacting targeted adjuvant radiation.
• No current guidelines exist for TBD localization after OPS.

Purpose of the Study:

• To establish consensus guidelines for TBD delineation after OPS.
• To improve the accuracy of targeted radiation therapy following breast-conserving surgery.

Main Methods:

• Modified Delphi method employed.
• Consensus achieved through a panel of 20 surgical and radiation oncology experts.
• Online member survey conducted for broader input.

Main Results:

• Six key recommendations developed for TBD delineation post-OPS.
• Over 80% expert agreement on all statements.
• Recommendations include surgical clip placement, detailed operative reports, and interdisciplinary communication.

Conclusions:

• Consensus guidelines for TBD delineation after OPS have been established.
• These recommendations aim to enhance focused radiation therapy delivery.
• Improved collaboration and standardized reporting are vital for optimal patient outcomes.
