Abstract

Aim

To establish consensus guidelines for a safe clinical practice of accelerated partial breast irradiation (APBI) interstitial multicatheter brachytherapy (BT).

Background

APBI with interstitial multicatheter BT has proved to be effective in the treatment of early stage breast cancer. This paradigm shift in the approach to early breast cancer conservative treatment, along with the existing controversies on the clinical practice of APBI, prompted the Spanish Brachytherapy Group (GEB) of the Spanish Societies of Radiation Oncology (SEOR) and Medical Physics (SEFM) to address BT APBI in a consensus meeting.

Materials and methods

Prior to the meeting, a survey with 27 questions on indication, inclusion criteria, BT modality, implant technique, image guidance and simulation, CTV and OAR definition, dose prescription and fractionation, dose calculation, implant quality metrics and OAR dose constrains was distributed. Items not reaching a level of agreement of 70% were discussed and voted during the meeting.

Results

26 Institutions completed the survey, 60% of them perform APBI procedures. The analysis of the survey showed consensus reached on approximately half the questions. An expert panel discussed the remaining items; thereafter, a voting established the definite consensus.

Conclusions

This document summarizes the consensus guidelines agreed during the meeting of the Spanish Brachytherapy Group SEOR-SEFM. Institutions with BT facilities available should offer interstitial BT APBI as a treatment option to patients fulfilling the inclusion criteria. Institutions willing to implement interstitial BT APBI are encouraged to follow the consensus guidelines established herein.
