Abstract:
Objective:To investigate the relationship between the expression of P16 protein and the clinico-pathology of squamous cell carcinoma(SCC) of buccal mucosa and its precursor lesions. Methods:The immunohistochemical stain against p16 was performed in 30 cases of SCC of buccal mucosa, 32 cases of buccal leukoplakia and buccal lichen planus and 10 cases of normal buccal mucosa. All data were analyzed quantitatively by imag analysis technique. Then, the results were compared with clinico-pathological parameters.Results:The positive expression of P16 protein was found in all normal buccal and hyperplasia mucosa (100.0%), in 9 out of 10 cases of atypical hyperplasia (90.0%), in 12 out of 30 cases of SCC of buccal mucosa (40.0%). The positive expression rate of P16 protein in SCC of buccal mucosa was significantly lower than that in atypical hyperplasia (P
