Objective:To investigate the expression of P53and proliferating cell nuclear antigen(PCNA)in oral squamous cell carcinoma(OSCC)and its chemosensitive predictive value to neoadjuvant chemotherapy(NACT) with Carboplatin and 5-Fu for the patients with OSCC.Methods:50 patients with T2~T4 OSCC were examined by using SP immunohistochemistry before and after two NACT courses.the correlation between expression level of PCNA and P53 and therapeutic effect was analyzed.Results:①Expression level of PCNA and P53 was significantly associated with response to chemotherapy(P <0.05);② The effective rates of PCNA high expression and P53 negative expression in OSCC before NACT was 90.00%
it was significantly higher than that of other expression types(P <0.05)
and the effective rates of PCNA low expression and P53 positive expression was 14.29%
it was significantly lower than that of other expression types(P <0.05).Conclusion:Expression level of both PCNA and P53 can be used as a chemosensitive predictive marker to neoadjuvant chemotherapy with Carboplatin and 5-Fu for the patients with OSCC
and combined analysis of PCNA and P53 expression has higher predictive value than that of either PCNA or P53.
