Table 3. Epidermal growth factor receptor (EGFR) expression in head and neck squamous cell carcinomas (SCC) in relation to mitotic index.

Mitotic index	Head and neck SCC
	EGFR-n (%)	EGFR+ n (%)	Total n (%)
< 10	12 (22.6)	9 (17.0)	21 (39.6)
≥ 10 < 20	6 (11.3)	8 (15.1)	14 (26.4)
≥ 20	2 (3.8)	16 (30.2)	18 (34.0)
Total	20	33	53 *

EGFR - = EGFR not detected; EGFR + = EGFR detected;

^*among the 54 patients, one patient had no evaluation of EGFR in SCC to compare with the mitotic index.
