Abstract:
Objective:To determine whether p53 protein overexpression correlated with early tumor recurrence in carcinoma of maxillary sinus.Method:Forty-five patients with T2NoMo squamous cell carcinoma of maxillary sinus were treated with operation and/or radiotherapy . The median follow up time was 3 years. The ratio of local control was 62.2% (28 patients) , as control group ; The ratio of local recurrence and/or metastasis was 37.8% (17 patients),as experiment group . Cancer specimens were obtained before treatment.p53 protein overexpression, which indicated a mutated p53 gene ,was analyzed by immunohistochemistry, using the mouse monoclonal antibody DO-7.Result:Approximately 88.2% of the carcinoma that recurred locally overexpressed p53 protein , compared with only 28.6% of those with local control (P<0.01) .No significant relation was noted between p53 protein overexpression and pathohistologic grade .Intensity of staining did not predict tumor recurrece.Conclusion:The study demonstrated that the p53 protein is an important prognostic marker on gene level for maxillary sinus carcinoma.
