Abstract:
Objective To detect the correlation of serum p53 antibody and p53 protein expression of cancer tissue in patients with colorectal cancer (CRC), and to evaluate if the serum p53 antibody might reflect the mutation of p53 gene in CRC. Methods One hundred and thirty-two patients with CRC and 36 patients with non-tumor disease were included in this prospective study. The presence of serum p53 antibody was determined by enzyme-linked immunosorbent assay (ELISA). Immunohistochemical analysis of tumors was performed to detect the accumulation of p53 protein. Results The positive rate of p53 antibody was 40.2% in patients with colorectal cancer and 2.9% in non-tumor patients,( P
