Assessment of the Prognostic Relevance of Serum anti-p53 Antibodies in Epithelial Ovarian Cancer

Gynecol Oncol. 1999 Jan;72(1):76-81. doi: 10.1006/gyno.1998.5101.


The objective of this study was to assess the prognostic relevance of preoperative serum anti-p53 antibodies in epithelial ovarian cancer. These autoantibodies were detected with a new generation enzyme-linked immunosorbent assay in blood samples preoperatively drawn from 86 patients with this malignancy. Serum anti-p53 antibodies were found in 3 (10.0%) of the 30 patients with stage I-II and 15 (26.8%) of the 56 patients with stage III-IV epithelial ovarian cancer (P = 0.09). We assessed in detail 44 patients with stage III-IV disease who underwent six cycles of first-line platinum-based chemotherapy. A pathological complete response at second-look was achieved by none of the 15 patients with serum anti-p53 antibodies compared to 24.1% of the 29 patients without autoantibodies (P = 0.09). However, the preoperative serum anti-p53 antibody status had no prognostic relevance for progression-free survival and survival. In conclusion, the assessment of preoperative serum anti-p53 antibodies seems to have a limited clinical value in the management of patients with advanced epithelial ovarian cancer.
