Background: Although systemic immune-inflammation index (SII) correlates with patient survival in various solid malignancies limited information is available in the setting of oral cavity squamous cell carcinoma (OCSCC).
Methods: We retrospectively reviewed 222 patients who underwent a resection of curative intent for patients with OCSCC. SII was determined prior to surgical resection as platelet count × neutrophil count/lymphocyte count.
Results: At a median follow-up of 30.6 months, 2-year disease-free survival (DFS) and overall survival (OS) rates were 63.9% and 76.4%, respectively. A high SII (>1047) was associated with poor performance status and disease extent. A low SII was independently associated with improved DFS (HR: 0.440, pp=0.007) rates.
Conclusions: SII values at diagnosis were associated with patient performance status, disease extent at the time of diagnosis, improved disease control rates, and improved patient survival.
