Abstract
Oral squamous cell carcinoma (OSCC) is the most common oral cancer. The prognosis depends most often on the stage of the tumor. In this study, 108 cases of OSCC treated at the Faculty of Dentistry, Khon Kaen University during 2006 to 2014 were analyzed retrospectively. Overall survival rate was assessed, whereas the univariate and multivariate Cox proportional hazards regressions were used to identify associations between various factors and the survival. The 5-year overall survival rate of the 108 patients was 69.4%. Univariate analysis showed that lymph node metastasis (p = 0.03; 95% CI = 1.06-4.17) and recurrence of tumor (p = 0.00; 95% CI = 2.52-8.08) were significantly associated with overall survival. On the other hand, only recurrence of tumor was found to have a significant influence on overall survival in multivariate analysis (p = 0.01; 95%CI = 2.03-10.48).
