Abstract

Objective: The aim of current study was to investigate the expression of Cyclin D1 and Ki-67 in primary and metastatic oral squamous cell carcinoma (OSCC) and their different histological grades. Methods: Paraffin embedded 30 oral squamous cell carcinoma (15 each of primary and cervical lymph node metastatic OSCC) were included in the study. Cyclin D1 and Ki 67 expressions were evaluated by immunohistochemistry and compared in primary and lymph node metastasis of OSCC and their histological grades. The data was analyzed using SPSS software. Results: The mean age of patients with primary OSCC was 53.47 ±16.67 years and 61.47 ±11.94 years in patients with metastasis. Males were comparatively affected more than females with tongue as the most common site involved in both primary and metastatic tumours. The mean size of primary and metastatic tumour biopsies were 1.16 mm and 3.93 mm respectively. Comparison of the expression of Cyclin D1 in these primary and metastatic OSCC revealed a statistically significant difference (p = 0.003) whereas it was insignificant for Ki-67 (p = 0.715). Conclusion: Cyclin D1 can be a useful marker in predicting aggressive or metastatic behaviour of OSCC on premier biopsies.
