Objectives The study aimed to assess the role of CD151-integrin α3β1 (INGA3) complex as a potential prognostic indicator in OSCC and to examine whether mapping of its expression in the invasive front separately from that in the rest of the tumour would have an impact on the predictive value of the results. CD151/INGA3 profiles were compared with that of EGFR. Materials and methods Protein distributions were analysed either in the whole tumour (W) or separately, (i) the main tumour mass (TU) and (ii) the invasive front (IF) in 83 OSCC samples using immunohistochemistry. Results and conclusion There was no statistical association between any of the proteins scored in W and clinicopathologic features or patient survival. When examined separately, significant associations were shown for (i) CD151 and EGFR in TU (p=0.036) and (ii) tumour grade and EGFR in both TU (p=0.045) and IF (p=0.030). INGA3 was present predominantly in the tumour–host interface, significantly stronger in IF than TU (p=0.021). An association with 5-year disease-free survival was close to significant for INGA3 (TU and IF) (p=0.050) but not the CD151/INGA3 complex. Expression of CD151/INGA3 at the IF might reflect tumour behaviour pertinent to patient outcome.
