This multidisciplinary conference aims to highlight all different aspects of organ preserving treatment in rectal cancer. With experts in the field from all over the world, we aim to create an atmosphere of an informal conference, where discussion is most welcomed. To promote this, there will be a debate and interactive discussions. In addition participants are encouraged to propose and discuss new trials in this conference. In the end, participants will go home with a thorough knowledge of the newest ideas in the treatment of early rectal cancers. We hope to welcome you in Leiden in November!
