Objectives. This study aims at investigating the prognostic values of serum
p53 protein and anti-p53 antibody in patients undergoing surgical treatmen
t for head and neck squamous cell carcinoma (HNSCC).
Methods. Serum p53 protein and anti-p53 antibody concentrations were determ
ined by an enzyme-linked immunosorbent assay (ELISA) in 75 patients with HN
SCC and 28 healthy controls. In 28 patients, formalin-fixed tumor tissues w
ere also available for immunohistochemical staining by an anti-p53 DO7 mono
clonal antibody. The results were correlated with the clinico-pathologic pa
rameters.
Results. The mean preoperative serum concentration of p53 protein in patien
ts with HNSCc was significantly higher than healthy controls (59.45 pg/mL v
s 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 significant
ly higher incidence (65%) or nodal metastasis compared with 27% nodal metas
tasis in patients with absence of serum anti-p53 antibody (p = .002).
Conclusion. Preoperative serum p53 antibody was a significant prognostic fa
ctor for nodal metastasis of HNSCC. (C) 2001 John Wiley & Sons, Inc.
