Abstract
Background
Squamous cell carcinoma antigen (SCC-Ag) level and C-reactive protein (CRP) have been shown to be associated with tumor invasion, lymph node metastasis, staging and survival in patients with oral squamous cell carcinoma (OSCC). The purpose of the present study was to analyze the relationship between preoperative levels of both SCC-Ag and CRP, with clinicopathologic factors and prognosis in OSCC patients.
Methods
A retrospective study was performed on 142 OSCC patients between March 2008 and March 2011. Their serum SCC-Ag and CRP levels were measured preoperatively.
Results
SCC-Ag level of ≥2.0 ng/ml and CRP level ≥5.0 mg/L were significantly associated with pathologic tumor status (P < 0.001), pathologic nodal metastasis (P = 0.001), tumor depth (≥10 mm vs. <10 mm, P < 0.001), disease-free survival (P ≤ 0.001) and overall survival (P ≤ 0.001). The influence of SCC-Ag and CRP level on disease-free survival (hazard ratio 4.046, 95 % confidence interval 1.698–9.692) and overall survival (hazard ratio 3.655, 95 % confidence interval 1.464–9.130) still existed after adjusting for tumor status, lymph node metastasis and tumor cell differentiation.
Conclusions
Concurrent high levels of both preoperative SCC-Ag and CRP levels act as a predictor for lymph node metastasis, advanced tumor stage and tumor recurrence. It therefore has significant potential as a biomarker for risk stratification in OSCC.
