Oral squamous cell carcinomas in age distinct population: a comparison of p53 immunoexpression

J Cancer Res Ther. 2013 Oct-Dec;9(4):587-91. doi: 10.4103/0973-1482.126452.

Abstract

Aims: The study aimed to assess the diffused expression of p53 protein in patients with OSCC and its association with age at diagnosis (using 50 years as a cut point).

Study design: Ten normal oral mucosa and sixty OSCC lesions from age-distinct patient populations were immunohistochemically analyzed for the expression of p53 protein.

Results: In OSCC cases, 31 out of total 60 cases (51.67%) showed positive expression for p53 protein and it was more common in older study group (56.67%) than in younger study group (46.67%) but the difference was not statistically significant. Moreover, there was also no significant difference in the p53 indices (percentage of p53 positive cells) between the two study groups (P = 0.827).

Conclusion: The alteration rates were found to be slightly higher in older patients although not statistically significant.
