Is receptor for advanced glycation end products ( RAGE ) important in the prediction of recurrence in human oral squamous cell carcinoma? Context: Receptor for advanced glycation end products (RAGE) has recently been recognized as a cancer-associated protein responsible for cancer progression and metastasis in gastrointestinal cancers. The aim was to examine the role of RAGE in oral squamous cell carcinoma (OSCC). RAGE expression was examined by immunohistochemistry in 74 OSCC patients and evaluated with a grading based on Allred's score. RAGE expression was compared with clinicopathological parameters including clinical stage, invasive depth, nodal metastasis, disease recurrence and disease-free survival. High-grade expression of RAGE (RAGE-H) was observed in 30 (40.5%) of 74 OSCCs. RAGE-H was associated with depth of invasion (P < 0.0001) and local recurrence (P < 0.0001), but not with histological differentiation, clinical stage or nodal metastasis. Disease-free survival in patients with RAGE-H was significantly worse than in those with low-level RAGE expression. Multivariate analysis showed RAGE-H to be an independent prognostic factor for disease-free survival in OSCC patients (P = 0.0022).

RAGE is a relevant factor in predicting disease recurrence and patients' prognosis in OSCC. Final Decision: yes
