The Systemic Immune-Inflammation Index and Albumin as Prognostic Predictors in Laryngeal Carcinoma.

BACKGROUND

Systemic inflammation via host-tumor interactions is currently recognized as the seventh cancer hallmark. The purpose of this study was to detect whether pretreatment peripheral indexes were associated with aggressive behavior and prognosis of laryngeal carcinoma patients.

METHODS

The pretreatment peripheral indexes such as albumin and systematic immune-inflammation index (SII) in 338 patients with laryngeal carcinoma were retrospectively recorded, the relationships between them and clinicopathological features and prognosis were analyzed.

RESULTS

A high SII value was significantly positively associated with age ( = 0.01), N stage ( = 0.022) and tumor differentiation ( = 0.001). A low albumin value was significantly negatively associated with age ( = 0.01), tumor location ( = 0.001) and T stage ( = 0.015), N stage ( = 0.001) and tumor differentiation ( = 0.001). Univariate and multivariate survival analysis showed that a high SII (HR: 2.415, 95% CI 1.400-4.184;  = 0.002), a low blood albumin content (HR: 3.194, 95% CI 2.030-5.025;  = 0.001) independently predicted poor overall survival (OS). However, neutrophil-lymphocyte ratio (NLR), platelet-lymphocyte ratio (PLR) and platelet distribution width (RDW) were not independent prognostic factors.

CONCLUSION

Pretreatment peripheral indexes SII and albumin could function as inexpensive indicators of aggressive behavior and be feasible and promising predictive biomarkers for prognosis in laryngeal carcinoma patients. Quantification of pretreatment SII and albumin may help physicians to design more effective management and follow-up strategies in laryngeal carcinoma patients.
