    Abstract:
    Serum p53 autoantibodies were studied in 82 patients with Stage 1 or 2 breast cancer using an ELISA assay. Tissue expression of p53 in these patients was also examined. High levels of serum p53 autoantibodies were detected in 48% (39/82) patients, while 23% (19/82) were tissue positive. Patients with high serum p53 autoantibodies levels were not significantly different to those with low levels with respect to, tissue p53, tumour grade, size, stage or oestrogen receptor status. Tissue immunoreactivity for p53 was significantly associated with tumour grade and negative oestrogen receptor status. Patients in both groups were followed for a median of over five years but the presence of p53 autoantibodies in serum was not prognostic with respect to disease free interval or survival. In this study detection of p53 autoantibodies in serum does not correlate with any of the usual tumour related prognostic factors, nor does it correlate with clinical outcome.
