Abstract

Introduction: Oral lichen planus (OLP) is suggested as a lesion capable of transforming to oral squamous cell carcinoma (OSCC). However malignancy potential of the lesion and its relationship to OSCC is a matter of controversy. Since uncontrolled cell proliferation is an indicator of malignant transformation, the aim of this study was to compare cyclin D1 expression in OLP and OSCC lesions. Materials &amp; Methods: In this descriptive-analytical study, cyclin D1 expression among 3 groups of epithelial hyperplasia ,OLP and OSCC each having 21 samples was investigated using immunohistochemistry staining through quantitative and semi-quantitative methods. One-way ANOVA, Kruskal Wallis, Mann-Withney and Chi-square were used for statistical analysis. Results: Quantitatively, cyclin D1 expression for epithelial hyperplasia, OLP and OSCC were 13.69±6.00, 28.38±3.53 and 66.94±14.49, respectively. Semi- quantitatively, number of stained cells for epithelial hyperplasia and OLP were less than 35 while for OSCC it was more than 35. Through quantitative and Semi- quantitative comparison, cyclin D1 expression among the three studied groups overally and either bilaterally was significantly different (P<0.05). Conclusion: The results showed that cell proliferation of OLP significantly was less than that of OSCC suggesting that is no relationship between the two although pre-malignancyability of OLP is not exactly ruled out. It seems that increasing cell proliferation might be related to malignancy transformation of OLP; therefore, continuous follow-up of the lesion is necessary.
