Graph analysis of association between clinical data and molecules expression.
A = smokers with OSCC had a higher expression of laminin-332 γ2 chain in BL and BL+SL than high risk oral cases (P < 0.0001).
B = the same was not observed in basement membrane (P > 0.05).
C = regarding MMP-9 expression, male patients with OSCC showed more stromal cells with citoplasmatic staining than high risk oral cases (P = 0.0054).
D = the same pattern was observed in patients older than 60 years (P = 0.0101).
E = the analysis of MMP-9 in invasive fronts demonstrated that smokers had a higher expression when compared with non-smokers (P = 0.0225).
F = group of patients with laminin-332 expression in BL+SL with OSCC showed a higher frequency of stromal cells with citoplasmatic staining of MMP-9 than high risk oral lesions (P = 0.003).
