Predictive Role of p53 Protein as a Single Marker or Associated to Ki67 Antigen in Oral Carcinogenesis

Table 1: Number (%) of Specimens with p53 Over-Expression and Specimens with p53 Over-Expression Associated with Samples with High Ki67/p53 Ratio from Normal Mucosa, Epithelial Hyperplasias, Epithelial Dysplasias and OSCC

	Normal Mucosa	Epithelial Hyperplasias	Epithelial Dysplasias	OSCC
number	13	32	27	54
Samples with p53 over-expression	0 (0%)	5 (15%)	10(37%)	31(57%)
Samples with p53 over-expression associated with samples with high Ki67/p53 ratio.	0 (0%)	16 (50%)	22 (81%)	50(93%)
