Summary

Cancer-derived inflammation attenuates the efficacy of adjuvant chemotherapy (CT) in postoperative or metastatic colorectal cancer (mCRC). However, its role in mCRC patients receiving first-line Bevacizumab combined with chemotherapy (Bev/CT) remains unknown. In this prospective observational study, three Bev/CT regimen cohorts (discovery cohort,n=249; Internal validation cohort: n=115; external validation cohort: n=159) and one CT regimen cohort (n=175) were enrolled. Overall survival served as the primary endpoint; clinical response and progression-free survival were secondary endpoints evaluated during follow-up. Investigators used the serum inflammation ratios to evaluate the association between systemic inflammation and clinical outcomes in Bev/CT- and CT-treated mCRC. Combined analysis of 12 cytokines (flow cytometry) and 92 immuno-oncology proteins (Olink) revealed Bev resistance mechanisms and prognosis-predictive biomarkers in Bev/CT treated patients.
