It is my privilege and great pleasure to invite you to ESTRO 2021 which will take place 27-31 August 2021 in Madrid, Spain.

We are all very eager to meet face-to-face again, to network and share. To make this happen, while ensuring the safety of our community, we have opted for a blended congress format of an in-person programme in Madrid enhanced by a digital component providing access to online material. We want to provide you with the best possible congress experience under all circumstances, and to foster broad and continuous participation.
