Moreover, LAG-3 expression was significantly higher in various cancers, including kidney renal clear cell carcinoma (KIRC), pancreatic adenocarcinoma (PAAD), skin cutaneous melanoma (SKCM), testicular germ cell tumors (TGCT), lymphoid neoplasm diffuse large B‐cell lymphoma (DLBC), and head and neck squamous cell carcinoma (HNSC), compared to their corresponding normal tissues (88). Here, LAG3 is linked to testicular germ cell tumor.
