Abstract
The aim of the present study was to analyze the prevalence and clinical importance of p53 gene mutations in surgically treated squamous cell lung carcinoma. Sixty patients were included. Fifty-one patients in stages I to IIIa were submitted to radical resection. Twenty-five samples tested positive for the p53 immunohistochemistry assay, and were analyzed for p53 gene mutations. Eleven mutations were found. Patients harboring p53 gene mutations suffered a higher incidence of recurrence and a higher mortality rate. Disease-free interval and overall survival were shorter for patients with mutated p53 gene (p=0.03 and p=0.005, respectively).
