Abstract

Overexpression of p53 correlates with neoplasia in many cytological specimens. To test the specificity of overexpressed p53 as a tumour marker for the detection of pancreatic cancer, we analysed cytological specimens of pancreatic juice samples from patients with pancreatitis or pancreatic carcinoma (n = 42) for p53 protein overexpression. p53 protein overexpression was found in 59% of patients with pancreatitis and 67% of patients with pancreatic carcinoma. Thus, the assessment of p53 protein overexpression is not useful in the diagnosis of pancreatic cancer. Overexpressed p53 during pancreatitis appears to be wild-type p53. Overexpression of p53 may result from DNA damage occurring during chronic inflammation. It is well established that p53 can induce apoptosis upon DNA damage. Consequently, we found apoptotic cell death in five out of five tested cytological preparations from patients with pancreatitis as well as in one out of one pancreatic carcinoma specimen.
