Session

Overview: Four international experts will discuss current results of very accelerated partial breast irradiation (VAPBI) trials using only 1 – 3 fractions in 1-2 days and corresponding perspectives. Jean-Michel Hannoun-Levi and Robert Kuske will report the entry criteria, techniques and results of VAPBI trials and comparison with contemporary results of Phase 3 APBI-trials. The similarities, differences and challenges will be critical discussed. Philip Poortmans and Icro Meattini will present critical overview of primary and secondary outcomes of main phase 3 trials using different approaches for APBI. Finally, the cost effectiveness of the different approaches for partial breast irradiation will be evaluated.
