Additionally, those patients with lower pretreatment SIRI (< 3.26) showed a significantly higher 5-year CR (90% vs 10%) than those with higher SIRI (≥ 3.26, p < 0.001). Patients with higher LMR had better 5-year overall survival (OS) (p = 0.01) and 5-year progression-free (PFS) (p = 0.005) rates than those with lower LMR in univariate analysis. Patients with lower SIRI had better 5-year OS (p < 0.001) and 5-year PFS (p < 0.001) than those with higher SIRI in univariate analysis. In the Cox regression analysis, SIRI (HR = 1.941, [95% CI: 1.223– 3.081], p = 0.005) and N classification (HR = 2.203, [95% CI: 1.327– 3.657], p = 0.002) were independent variables of 5-year OS. In addition, SIRI (HR= 2.127, [95% CI: 1.214– 3.725], p = 0.008), T classification (HR = 2.18, [95% CI: 1.072– 4.433], p = 0.031), and N classification (HR = 2.329, [95% CI: 1.395– 3.889], p = 0.001) were independent variables of 5-year PFS.Conclusion: Pretreatment SIRI is superior to LMR in predicting treatment response and clinical outcomes among patients with laryngeal/hypopharyngeal cancer treated by CRT/RTO. SIRI may be adopted in the treatment of laryngeal/hypopharyngeal cancer by CRT/RTO.Keywords: head and neck squamous cell carcinoma, hypopharyngeal cancer, laryngeal cancer, systemic inflammation response index, neutrophil–lymphocyte ratio, lymphocyte–monocyte ratio
