Marc Peeters, ESMO 2018 – Using Biomarkers to Guide Treatment in Colorectal Cancer

In this interview at ESMO 2018, Marc Peeters talks to touchONCOLOGY about colorectal cancer tumour location and biomarkers. He explains that left-sided cancers have a better prognosis and suggests some possible reasons for this. Dr Peeters also discusses how the use of biomarkers has developed in the last 10 years and how treatment and prognosis can be guided using these biomarkers. This development is largely down to progress in technology, such as easier access to next generation sequencing, and the advent of liquid biopsies. Unfortunately, there are certain types of colorectal cancers with a poor prognosis, such as RAS- and BRAF-mutated tumours. There is still a need for biologics that can be added to standard chemotherapy in patients with these tumours.
