Table 1—

Mean ± SD mitotic index and intensity of 5-lipoxygenase–specific staining in sections of oral, UV radiation–induced, and cutaneous SCCs in cats (20 tumors of each neoplastic form from 60 cats [1 tumor/cat]).

Variable	Oral	UV radiation–induced	Cutaneous	ANOVA P value
Mitotic index	1.2 ± 1.1	1.1 ± 1.0	1.9 ± 2.1	0.639
Stain intensity	2.3 ± 0.6	1.6 ± 0.9	0.8 ± 0.7	< 0.001
Correlation P value	0.201	0.914	0.143	—

One section from each cat was evaluated and scored. Staining intensity was subjectively scored as follows: 1 = weak staining intensity, 2 = moderate staining intensity, and 3 = marked staining intensity. A value of P < 0.05 was considered significant.
