We are warmly inviting everyone to join the 6th Annual OncoAlert Colloquium, a week-long “Best of the Year” virtual event featuring leading oncologists organised by OncoAlert. Each day focuses on a different tumour group, covering medical, surgical, and radiation oncology, pathology, diagnostics and advocacy. Attendees can interact live with faculty, discuss trials, and explore the most relevant data impacting daily practice.
This year, ESSO experts will join the highlights on breast cancer surgery presented by Isabel Rubio, lower GI surgery presented by Johnn Herrera Kok, and upper GI surgery presented by Marco Inama.
The Colloquium is free and on-demand, but registration is required. On behalf of ESSO and all partners (OncoAlert, ESGO, MASCC, and SIOG), we look forward to seeing you there.
Dates: February 2–8, 2026
