    Abstract
    Objectives This study aims at investigating the prognostic values of serum p53 protein and anti-p53 antibody in patients undergoing surgical treatment for head and neck squamous cell carcinoma (HNSCC). Methods Serum p53 protein and anti-p53 antibody concentrations were determined by an enzyme-linked immunosorbent assay (ELISA) in 75 patients with HNSCC and 28 healthy controls. In 28 patients, formalin-fixed tumor tissues were also available for immunohistochemical staining by an anti-p53 DO7 monoclonal antibody. The results were correlated with the clinicopathologic parameters. Results The mean preoperative serum ...

    Objectives This study aims at investigating the prognostic values of serum p53 protein and anti-p53 antibody in patients undergoing surgical treatment for head and neck squamous cell carcinoma (HNSCC). Methods Serum p53 protein and anti-p53 antibody concentrations were determined by an enzyme-linked immunosorbent assay (ELISA) in 75 patients with HNSCC and 28 healthy controls. In 28 patients, formalin-fixed tumor tissues were also available for immunohistochemical staining by an anti-p53 DO7 monoclonal antibody. The results were correlated with the clinicopathologic parameters. Results The mean preoperative serum concentration of p53 protein in patients with HNSCC was significantly higher than healthy controls (59.45 pg/mL vs 16.4 pg/mL, p = .007). Preoperative serum p53 antibody was present in 23 (31%) patients and was present in one healthy control. Eighteen (62%) tumor tissues showed p53 overexpression by immunohistochemistry. The presence of serum anti-p53 antibody before operation was associated with a significantly higher incidence (65%) of nodal metastasis compared with 27% nodal metastasis in patients with absence of serum anti-p53 antibody (p = .002). Conclusion Preoperative serum p53 antibody was a significant prognostic factor for nodal metastasis of HNSCC. © 2001 John Wiley & Sons, Inc. Head Neck 23: 286-291, 2001.
