OBJECTIVES/HYPOTHESIS: Previous studies have demonstrated a relationship between elevated serum squamous cell carcinoma (SCC) antigen (SCC-Ag) levels and shorter survival in cancer patients. Few studies, however, have investigated the role of serum SCC-Ag levels in oral SCC (OSCC). This study was conducted to analyze the relationship between preoperative SCC-Ag levels, clinicopathologic factors, and prognosis in OSCC patients. STUDY DESIGN: Retrospective case-control study. METHODS: Seventy-nine OSCC patients from Chang Gung Memorial Hospital were retrospectively recruited between April 2008 and March 2010. Serum SCC-Ag levels were measured preoperatively. RESULTS: An SCC-Ag level of ≥2.0 ng/mL was significantly associated with the pathologic tumor status (P < .001), pathologic nodal status (P = .037), lymph node extracapsular spread (P = .016), and tumor depth (>10 mm vs. ≤10 mm, P < .001). It was not significantly associated with histologic differentiation (P = 1.000). A univariate analysis revealed that positivity for SCC-Ag was associated with disease-free survival (DFS) (P = .034) and overall survival (OS) (P < .001). In SCC-Ag-positive patients, the distant metastatic rate was higher than in the SCC-Ag-negative patients (P = .053). CONCLUSIONS: This study demonstrated that preoperative SCC-Ag is a good marker of pathologic lymph node metastasis, an advanced tumor stage, and a higher rate of distant metastasis. The preoperative SCC-Ag level is a potential prognostic indicator in DFS and OS, but studies with a longer follow-up period are needed to confirm these results.
