Clinical Significance of Cyclin Expression Profiling in Ocular Surface Squamous Neoplasia.
2021
Ocular surface squamous neoplasia (OSSN) can recur, metastasize, and even cause death. Cyclins regulate the cell cycle progression at different phases and its dysregulation is associated with uncontrollable cell growth and malignant transformation of the cell. Overexpression of cyclin has been reported in various malignancies and is associated with poor prognosis. However, the role of cyclins in OSSN remains unexplored. This study has been designed to assess the prognostic significance of cyclin (cyclin B1, E1, and D1) immunoexpression in 100 OSSN patients. The targeted proteins demonstrated overexpression of cyclin B1, cyclin E1, and cyclin D1 in 55%, 37%, and 56% OSSN cases prospectively. A gradual and significant increase in the cyclin B1 (P=0.01) and cyclin D1 (P=0.005) expression was seen from Tis to the T4 category. Overexpression of cyclin B1 was associated with poor disease-free survival and worst prognosis in both early (P=0.03) as well as advanced T staged (P=0.038) OSSN patients. Overexpression of cyclin E1 was associated with worst disease-free survival (P=0.01) and poor prognosis in advanced stage OSSN patients. Our findings suggest that cyclin B1 and cyclin E1 have prognostic relevance in OSSN patients, and therefore are recommended for detecting high-risk category cases. A significant increase in the expression of cyclins from early to advanced stage indicates that cyclins play an important role in the pathogenesis of OSSN patients.
