APBI 2016

Conclusions

There is no optimal technique for APBI, all techniques have pros and cons It is very difficult to directly compare the techniques partly because: • They are fundamentally different

• Different definition of target and treated volume • Different total dose, fraction number, dose/fraction • Different timing in relation to surgery and systemic therapy

• Different demand for technical skills • Different cost and cost-effectiveness • Some techniques very dependent on breast size, localization of lumpectomy cavity • Different potential for causing acute and late morbidity • Importantly also different local control rates
