title: [Serum anti-p53 antibodies in gastric cancer patients].
abstract: Mutation of the p53 gene belongs to the most common genetic alteration in human cancer. Prognostic significance of serum anti-p53 antibodies in patients with gastric cancer is still a matter of controversy. The aim of the study was to estimate the presence of anti-p53 antibodies in serum of gastric cancer patients and relationship between anti-p53 antibodies and chosen clinical and pathomorphological data age, sex, localization of cancer, histology, stage of disease, metastases to lymph nodes and the time of survival.
  
  
  METHODS
  Serum samples from 71 patients with gastric cancer were analyzed by specific enzyme-linked immunosorbent assay (ELISA) to determine the presence of serum anti-p53 antibodies. The results were statistically compared with clinical and pathological features and postoperative survival.
  
  
  RESULTS
  Anti-p53 antibodies were detected in 16 (23%) gastric cancer patients. The presence of p53 antibodies was connected with intestinal tumor type (p < 0.05) and older age (p = 0.0035). There were no association between anti-p53 antibodies, stage and the time of survival.
  
  
  CONCLUSIONS
  These results suggest that in gastric cancer patients serum anti-p53 antibodies detected by ELISA are not predictor of prognosis.
