Abstract
PURPOSE: This study investigated prognostic factors and useful predictors for survival in patients with oral squamous cell carcinoma. PATIENTS AND METHODS: The medical records of all patients with oral squamous cell carcinoma who underwent curative surgery with or without adjuvant radiation from 2009 through 2011 were retrospectively reviewed. RESULTS: Seventy-seven patients (63 men and 14 women) were enrolled. The 2-year disease-free and overall survival rates were 67.5% and 74%, respectively. Multivariate analyses showed that a diagnostic delay longer than 2 months (hazard ratio [HR]=4.43; 95% confidence interval [CI], 1.26-15.51; P=.02), T3 or T4 tumor (HR=4.40; 95% CI, 1.91-10.12; P=.001), neck metastasis (HR=1.96; 95% CI, 1.21-4.37; P=.01), and stage III or IV disease (HR=3.94; 95% CI, 1.64-9.47; P=.002) were independent adverse factors for survival rate. CONCLUSION: Oral squamous cell carcinoma is an important health issue associated with poor survival. A diagnostic delay longer than 2 months, T3 or T4 tumor, neck metastasis, and stage III or IV disease were independent adverse factors for subsequent survival rate and locoregional recurrence in patients with oral squamous cell carcinoma.
