Overexpression of Epstein-Barr virus-encoded latent membrane protein-1 (LMP-1) in oral squamous cell carcinoma

BMC Oral Health

Table 3 The percentage of LMP-1 expression according to the staining patterns in normal oral mucosa, OL without dysplasia, OL with dysplasia and OSCC

Tissue type (no. of total cases)	Mean percentage of positive cells (mean ± SD)
Tissue type (no. of total cases)	Nucleus	Cytoplasm	Nuclear plus cytoplasm
Normal oral mucosa (10)	26.22 ± 12.26 *	0 **	0.14 ± 0.31*
OL without dysplasia (27)	27.97 ± 9.38**	0.01 ± 0.04**	0.05 ± 0.20**
OL with dysplasia (42)	32.29 ± 16.38*	0.64 ± 2.26**	1.16 ± 4.02**
OSCC (36)	44.30 ± 17.86	3.18 ± 4.48	12.19 ± 22.29

OL = oral leukoplakia
OSCC = oral squamous cell carcinoma
*P < 0.05 and **P < 0.001 statistically significant difference compared with OSCC
