Abstract

Flotillin-2 (Flot-2) is an important component of cellular membrane, which involves in various cellular processes and recent studies have revealed that Flot-2 played important roles in cancer progression. The expression and prognostic impact of Flot-2 in oral squamous cell carcinoma (OSCC) have not been well studied. So, a tissue microarray (TMA) based on immunohistochemical analysis of surgical resection of tumor tissues of 78 cases of OSCC patients and 27 cases of adjacent non-cancerous squamous epithelium tissues was conducted. This study focused on detecting Flot-2 expression and analyzing its prognostic impact on OSCC. The result showed that the positive percentage of Flot-2 expression in OSCC (74.4%, 58/78) was significantly higher than that in adjacent non-cancerous squamous epithelium tissues (25.9%, 7/27) (P<0.001). Additionally, the positive expression of Flot-2 in OSCC patients with a history of alcohol consumption was significantly higher than those nonusers (P=0.027). Both univariate and multivariate survival analysis indicated that increased expression Flot-2 protein was significantly correlated inversely with overall survival rates in OSCC patients (P=0.046, P=0.002). Taken together, positive expression of Flot-2...Continue Reading
