SCCA1 expression in various tissues by IHC.

Classification	Number	—	+	++–+++	P value
Squamous cell carcinomas	30	21	5	4	0.038^a
High differentiated	3	3	0	0	0.406^b
Moderately differentiated	11	9	2	0

Normal lung tissue	20	9	10	1
Metastatic carcinoma	29	16	5	8	0.029^c
Other types	20	12	6	2	0.001^d

^a𝑃<0.05 by LSD, squamous cell carcinomas versus normal lung tissue. ^b𝑃>0.05 by ANOVA, high differentiated versus moderately versus poorly. ^c𝑃<0.05 by LSD, metastatic carcinoma versus normal lung tissue. ^d𝑃<0.05 by LSD, other types versus normal lung tissue.
