CAF-related signatures showed stronger poor prognosis association in those patients with advanced colon tumors than in initial stages and in those patients with CMS4 than in CMS1-3. Patient classification is based on tumor microenvironment differences defined by CAF-derived signatures, in order to identify those patients with high/low risk of poor outcome.
