ABSTRACT
Objective:
To evaluate the expression through immunohistochemistry of galectins -1, - 3 and -7 in cases of lip squamous cell carcinoma (SCC) in association with clinical data and morphological parameters proposed by Bryne (1998). Material andMethods:
Thirty paraffin-embedded SCC cases were submitted to histological sections. Two independent pathologists performed the analysis of galectins -1, -3 and -7 through light microscopy evaluating the presence or absence of marking and intensity. The expressions of these proteins were submitted to statistical analysis (chi-square test, Fisher's exact test and Binomial test for the comparison of proportions).Results:
Positive expression of galectins -1 and -3 was observed in 93.3% and 43.3% of cases, respectively. However, there was no statistically significant association between these proteins and the clinical variables used. Galectin-7 immuno-expression was present in all cases evaluated and showed statistical significance between marked cell type (parenchyma cells) and regional metastasis and between marked cell type (parenchyma cells) and histological gradation.Conclusion:
Changes in the galectins -1, -3 and -7 expression suggest the participation of these proteins in the regulation of cellular functions and that the immuno-expression of these proteins can act as a marker of the biological behavior of lip squamous cell carcinoma.
