P53 Antibodies

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.

Carcinoembryonic antigen (CEA) assays (2536) were performed in 380 disease-free breast cancer patients after radical mastectomy. In the 334 evaluable patients with 3 or more determinations, the overall relapse rate after a median follow-up of 29 months was 11 %. Of 203 patients with normal CEA values, 19 (9.3 %) relapsed. In the 50 patients with the highest CEA value greater than 20 ng/ml, the relapse rate was 26 %; in the 12 patients with gradually increasing CEA elevations it was 50 %. However, CEA was unable to predict recurrence in N- patients. Premastectomy N+ was significantly associated with greater than 20 ng/ml or gradually increasing CEA values, suggesting the lack of an independent prognostic value of CEA in our patient population.
