Table 1.

Percentages of cells positive for 5-mc and weighted averages of immunostaining scores for 5-mc in normal and uninvolved oral epithelium, dysplasia, and squamous cell carcinoma.

Tissue type	% of cells positive for 5-mc, mean (median)	Weighted average of 5-mc score, mean (median)
Normal oral epithelium of noncancer (n = 93)	37 (35)^a	0.53 (0.47)^b
Uninvolved oral epithelium of cancer (n = 44)	34 (33)^c	0.48 (0.39)^d
Dysplasia of cancer (n = 42)	48 (50)^e	0.72 (0.69)^f
Cancer (n = 39)	51 (55)^g	0.77 (0.80)^h

Abbreviation: 5-mc, 5-methylcytosine.
