TIGIT and testicular germ cell tumor: The strong survival improvement associated with TIGIT expression levels (reported in Table 2 and in Fig. 4B) suggests that TIGIT-inhibitors drugs may be clinically beneficial in thymoma and Testicular Germ Cell Tumors, while TIGIT-agonists may improve survival in SKCM, READ, UCEC, ACC, BRCA, CESC, PRAD and HNSC patients.
