✦ Synopsis

The antibody reactivity of human breast cancer sera was evaluated by means of radioimmunoassays and established breast cancer cell lines. When tested against the MDA-MB 231 cell line, 30 of 324 sera had detectable antibody reactivity. All the positive sera, however, reacted with other cell lines as well, generally including cultures initiated from sites other than breast cancers, and often including animal cell cultures. In competition radioimmunoassays the positive sera fell into various groups, indicating that a diversity of antigens was being detected. Two patients' sera identified antigens that were expressed on breast cancer cells but that were not expressed on an assortment of other cell types. Sera like these two, which identify potentially important tumor markers, could serve as valuable reagents for the analysis of the tumor-assiciated antigens of human breast cancer cells.

## Abstract Much interest is presently being shown toward identifying markers for the detection of breast cancer. To detect autoantibodies that could represent diagnostic markers for breast cancer, we comprehensively analyzed serum autoantibodies showing immunoreactivity to proteins in tumor tissue

## Abstract Antibodies reacting with the host protein p53 were found in the sera of patients with primary or secondary carcinoma of the breast. Fourteen out of the 155 sera from breast cancer patients tested were positive for anti‐p53 antibodies (9%) and no positives were detected among 164 control
