The expression patterns of these molecules were consistent with those reported in previous studies that examined their expression in human tumor tissue.[4, 9, 10, 21] B7-H1 and B7-H3 were more likely to be expressed in NSCLC cells than in normal lung tissues, and B7-H1/B7-H3 expression was associated with decreased OS in patients with NSCLC. Here, CD274 is linked to neoplasm.
