Most recently, Jin et al. (74, 75) looked for (i) autoantibodies directed against Cancer Antigens 19-9 (CA19-9) and 15-3 (CA15-3), carcinoembryonic antigen (CEA), c-Myc, p53, heat shock proteins (Hsp)27 and Hsp70, in the sera of HPV-infected patients; and (ii) for six tumor-associated proteins, of which combinations of Sialyl Lewis A and p53 would discriminate cancer from normal condition in exfoliated cervical cells. This evidence concerns the gene TP53 and cancer.
