BACKGROUND: Apoptosis inhibition is a major tumorigenic factor. Bcl-2 dysregulation and TP53 mutation status, which may correlate with autoantibody generation, contribute to impaired apoptosis. OBJECTIVE: This study aimed to investigate the prognostic value of circulating Bcl-2 and anti-p53 antibodies (p53Abs) in a 17.5-year follow-up of breast cancer patients. We also analyzed the correlations of Bcl-2 and p53Abs with various clinicopathological parameters in order to assess their impact on tumor aggressiveness. METHODS: Serum Bcl-2 and p53Abs levels were analyzed by the enzyme-linked immunosorbent assay (ELISA) in 82 patients with invasive breast cancer and twenty individuals without malignancy. RESULTS: Serum Bcl-2 and p53Abs levels in breast cancer patients were significantly higher than those in controls. Patients with high levels of Bcl-2 (cut-off 200 U/ml) had a poorer prognosis (17.5-year survival) than those with lower Bcl-2 values. In combined analysis the subgroup of patients with elevated p53Abs (cut-off 15 U/ml) and elevated Bcl-2 (cut-offs 124 U/ml and 200 U/ml) had the worse prognosis in 17.5-year survival. In correlation analysis p53Abs and Bcl-2 were associated with unfavorable clinicopathological parameters. CONCLUSIONS: Our results suggest that breast cancer patients with high serum levels of p53Abs and Bcl-2 present an especially unfavorable group in a long follow-up.

Aim and Background The incidence and mortality due to oral cancer have increased worldwide. In India, the use of tobacco has been found to be the major etiological factor for the development of oral cancers. Various studies on serum p53 antibodies have suggested their clinical importance as prognostic markers in cancer. However, there is a dearth of data on serum p53 antibodies in oral cancer patients in India. The present study was carried to evaluate the clinical significance of serum p53 antibodies in oral cancer. Materials and Methods The serum p53 antibody status was analyzed by means of ELISA in 55 healthy individuals, 60 patients with oral precancerous conditions, 75 untreated oral cancer patients, and 86 follow-up blood samples of the oral cancer patients. Results We found serum p53 antibodies in 23% of cancer patients. The frequency of p53 antibody positivity was higher in patients with lymph node metastasis, advanced disease and well-differentiated tumors. Furthermore, p53 antibody positivity strongly correlated with poor treatment outcome in cancer patients. Kaplan-Meier survival analysis showed significantly poorer disease-free survival in patients with serum p53 antibodies. Conclusion The results of this study suggest the usefulness of serum p53 antibodies in the prognostication of oral cancer patients.
