Abstract: PURPOSE: To investigate the expression of type I interferon receptor 1(IFNAR1) in oral squamous cell carcinoma (OSCC) and normal mucosa, and to explore its relationship with clinical pathological characteristics and prognosis. METHODS: The expression of IFNAR1 in 108 cases with OSCC and 16 cases with normal oral mucosa was detected by immunohistochemistry. The relationship between the expression of IFNAR1 in OSCC tissues and clinical pathological characteristics were analyzed. The data were analyzed with SPSS17.0 software package. RESULTS: The expression of IFNAR1 in OSCC was significantly higher than that in normal oral mucosa. The expression of IFNAR1 was closely correlated with T stage, cervical lymph node metastasis, TNM stage and pathological differentiation (P<0.05); while gender, age, location, smoking and drinking had no correlation with IFNAR1 (P>0.05). IFNAR1 expression was an important factor to predict prognosis of OSCC patients with HR=1.879(95% CI=0.967-3.651, P=0.063). Patients with higher expression of IFNAR1 had poorer prognosis shown by Log-rank test (P=0.057). CONCLUSIONS: The expression of IFNAR1 in OSCC was significantly higher than that in normal oral mucosa, and it is a potential risk factor for OSCC. It has a tendency to be related to the prognosis of OSCC patients. IFNAR1 expression in tumor tissues can be a surrogate to select patients who can benefit from interferon alpha treatment in OSCC.
