Aim: Bc12 and P53 genes products continue to be extensively studied in breast cancer in order to identify factors and to optimise therapeutic approaches. We evaluated p53 and bc12 immuno-reactivity in 72 Tunisian breast cancers.

Methods and results: a total of 72 paraffin-embedded tumors were evaluated for nuclear p53 and cytoplasmic bc12 immuno-reactivity. The results were semi-quantitated. The P53 over-expression was seen in 65% of cases, and was significantly associated with high histological grade (p < 0.001), and correlated inversely to bcl2 (p = 0.02). Bcl2 expression was observed in 54% of cases. No correlation was seen between bcl2 expression and classic prognostic factors.

Conclusion: in breast cancer P53 over-expression appears to be indicative of biologic aggressiveness and p53 accumulation reduces expression of bcl2 in tumors.
