A clear correlation exists between high B7-H3 expression and various tumor growth parameters, including fewer tumor-infiltrating lymphocytes, faster cancer progression, and poor clinical outcome in several cancers such as pancreatic ductal adenocarcinoma (PDAC), prostate cancer, ovarian cancer, lung cancer, and clear cell renal carcinoma [8,11,36,37,38,39]. Here, CD276 is linked to clear cell renal carcinoma.
