Table 3. For CCR6, indicates the number of slides that were allocated to each staining category according to disease stage.

CCR6	0–25%	25–50%	50–75%	75–100%
Stage I	19	7	3	3
Stage II	9	0	0	0
Stage III	6	0	0	2
Total	34	7	3	5

Samples were divided into four categories according to percent of tumor cells staining positive: 1. 0–25% of tumor cells stained positive, 2. 25–50% of tumor cells stained positive, 3. 50–75% of tumor cells stained positive, 4. 75–100% of tumor cells stained positive.
