The lymphocytic population in thymomas (especially in subtypes AB and B1), which consists of accompanying immature T cells, presented higher EphB6 H-score compared with lymphocytes in thymic carcinomas (p < 0.001) (Figure 5b), where they probably represent antitumoral immune reaction; conversely, lymphocytic EphB1 expression was higher in carcinomas (p = 0.026) (Figure 5a). This evidence concerns the gene EPHB6 and thymoma.
