Background: Precision delivery of adjuvant chemotherapy (ACT) improves healthcare efficiency and postoperative quality of life in stage II–III colorectal cancer (CRC). However, there remains an unmet need for identifying biomarkers that can predict therapeutic responses to 5-fluorouracil (5-FU) and oxaliplatin.
Methods: We analyzed three independent cohorts (1676 stage II–III surgical cases) to evaluate the prognostic role of 12 inflammatory indices. A novel Chronic Inflammatory Comprehensive Signature (CICS) was developed using multivariable Cox regression. Three-year recurrence-free survival (RFS) and overall survival (OS) were compared between CICS-stratified subgroups (CICS-L vs CICS-H) receiving 5-FU- or oxaliplatin-based ACT.
Results: Two novel inflammatory ratios (FPSIIR, FPSIRIR) and six composite scores (FPSIIS, FPSIRIS, FPSIRS, FASIIS, FASIRS, FASIRIS) independently predicted prognosis across all three cohorts (all plog-rank< 0.05). The CICS demonstrated an AUC of 0.690 for outcome prediction, increasing to 0.724 when combined with CEA-CA19-9. CICS-H patients exhibited reduced chemosensitivity to both agents, with therapeutic benefits primarily confined to the CICS-L subgroup. Comparable favorable RFS was observed in stage II CICS-L patients undergoing 5-FU monotherapy or oxaliplatin-based ACT versus non-ACT treatments (97.73% vs 91.02% vs 91.46%, plog-rank=0.33). Superior survival outcomes and a lower recurrence rate were observed in stage II CICS-H patients receiving 5-FU compared to those receiving oxaliplatin-based ACT. Consistent oxaliplatin benefits were observed in CICS-H and CICS-L patients compared to 5-FU-treated cases in the stage III subgroup. Optimal ACT regimens for patients with CICS-L and CICS-H differ in different stages. The CICS strategy can help patients select a more optimal ACT regimen (RR=0.47, 95% CI=0.35– 0.62, p< 0.01) and enhance therapeutic efficacy (HR=0.70, 95% CI=0.53– 0.92 for RFS; HR=0.70, 95% CI=0.47– 0.97 for OS in stage III CRC).
Conclusion: CICS-quantified cancer-derived inflammation inversely correlates with the therapeutic responsiveness to 5-FU/oxaliplatin. A CICS-guided strategy maximizes survival outcomes while precision-deescalating chemotherapy use without compromising outcomes, establishing a biomarker-driven paradigm for personalized postoperative management of CRC.
