Abstract:
BACKGROUND AND OBJECTIVES: The p53 protein is a 53 kD phosphoprotein. It is also one of the early recognition markers of malignancy and can be used to predict the aggressive behaviors of tumor. The human papilloma virus (HPV) is a species-specific, epitheliotrophic, double-stranded DNA virus. The purpose of this study was to evaluate the expression rate of p53, and to investigate whether a correlation exists between the rate of recurrence and the severity of lesion. We also investigated whether p53 expression rate and HPV affect recurrence and carcinogenesis of inverted papilloma. MATERIALS AND METHODS: Twenty-two cases of the inverted papilloma and 6 cases of squamous cell carcinoma arising in the inverted papilloma were used for the study. We used immunohistochemical staining for p53 and performed the molecular study of HPV DNA with in situ hybridization (ISH) on the paraffin embedded materials. RESULTS: 1) The overall expression rate of p53 was 39% (11/28). A significant correlation was observed between p53 protein accumulation and the severity of the lesion (p=0.0015). 2) Seven of 11 patients who tested positive for p53 showed recurrence, whereas two of the 12 patients who tested negative for p53 showed recurrence. There was a correlation between the rates of p53 expression and recurrence (p=0.029). 3) The HPV was detected in four cases (13%) of inverted papilloma. There was no statistical significance between HPV and the rate of recurrence(p=0.147). CONCLUSION: The results demonstate that p53 mutations and HPV may play a role in the oncogenesis of inverted papilloma.
