Expression of TAP2 protein in lung tumours

Histological type	Low	Intermediate	High
ADC (56 samples)	22/56 (39%)	25/56 (45%)	9/56 (16%)
SCC (29 samples)	20/29 (69%)	7/29 (24%)	2/29 (7%)
Undif (42 samples)	24/42 (57%)	10/42 (24%)	8/42 (19%)
Other (8 samples)	6/8 (75%)	2/8 (25%)	0/8 (0%)
Total	72/135 (53%)	44/135 (32%)	19/135 (14%)

TAP2 protein expression in a cohort of 135 FFPE lung tumour samples was performed by IHC. Data correspond to TAP2 H-score. Low: 0 ≤ H-score ≤ 70; Intermediate: 80 ≤ H-score ≤ 140; High: 160 ≤ H-score ≤ 200. H-score = % TAP2⁺ cells × TAP2 intensity. TAP2 intensity varies from 0 to 2. Normal cell H-score = 200
