Abstract：
OBJECTIVES:The purpose of this study was to evaluate the association between the serum anti-p53 antibodies (Abs) status and the p53 protein status in the sera and tumors as well as clinical or pathological parameters in bladder cancer patients retrospectively. METHODS:Serum samples from 100 patients with bladder cancer were assayed for anti-p53 Abs and p53 protein by enzyme-linked immunosorbent assay (ELISA). A monoclonal antibody DO7 was used for immunohistochemical staining of tumor p53 protein. RESULTS:Prevalences of serum anti-p53 Abs, serum p53 protein and tumor p53 protein were 12, 1 and 63%, respectively. There was a significant correlation between serum anti-p53 Abs status and factors including tumor stage, tumor grade, and tumor p53 protein status. In the univariate analysis, tumor stage, tumor grade, serum anti-p53 Abs status, and tumor p53 protein status were significantly associated with an increased risk of death. Multivariate analysis showed that tumor stage was the only independent prognostic factor among the factors examined. CONCLUSIONS:The present study suggests that serum anti-p53 Abs had a limited value as a tumor marker in bladder cancer patients. Further studies to elucidate the mechanism of anti-p53 Abs production will be necessary for a better understanding of the immune status in bladder cancer patients.
