Abstract:
:The goal of the present study was to investigate whether p53 antibodies (Abs) could be a relevant marker for papillary thyroid carcinoma (PTC). Three types of enzyme-linked immunosorbent assay (ELISA) methods were developed for the detection of p53 Abs, including p53-ELISA, phage-SS-ELISA, and phage-SP-ELISA. A total of 304 patients, including 117 cases with thyroid adenoma and 187 PTC patients, were enrolled in this study. Expression of p53 protein and mutation in BRAF gene were evaluated in paraffin-embedded tissue from 44 patients with PTC, in order to elucidate their correlations with the presence of p53 Abs. Compared with p53-ELISA and phage-SS-ELISA, phage-SP-ELISA presented the highest detection efficiency of p53 Abs in patients with PTC, and a combination of these three ELISA systems could make the detection of p53 Abs more sensitive than using each of the individual ELISA methods. Furthermore, p53 Abs was positively associated with clinical stage (P = 0.044), node metastasis (P = 0.010), and p53 protein accumulation (P = 0.019). These results indicate that serum p53 Abs could be a useful marker for PTC.
