RSF-1 expression correlates with poor clinical outcome in oral squamous cell carcinoma (OSCC). A: Kaplan-Meier survival analysis shows an association between RSF-1 protein expression and shorter overall survival. Patients with immunostaining scores of 0 to + 2 were considered to have low RSF-1 expression; patients with scores of +3 or +4 were considered to have high RSF-1 expression. B: Correlation analysis of RSF-1 expression level and pathological pT status demonstrates that cases with higher pT stages (pT3 and pT4) have higher RSF-1 levels than do lower stage cases (pT1 and pT2).
