Abstract
We examined the relationship between p53 expression and clinicopathologic parameters in anal carcinoma. p53 immunoreactivity was detected in 14/18 (77.7%) tumors. Significant association was found between p53 expression and depth of invasion. There was no significant association between p53 expression and histologic type, lymph node metastasis, age and prognosis. Possibly the genetic pathway to anal carcinoma involving p53 gene overexpression confer aggressive growth pattern, but it does not result in worse prognosis. The absence of correlation between p53 overexpression and prognosis could be explained by tumors negative for mutations having an excess of wild-type p53 protein.
