The strongest CAF-STAT3 association (Partial cor = 1, p < 0.05) was observed in cholangiocarcinoma (CHOL), GBM, kidney chromophobe (KICH), kidney renal papillary cell carcinoma (KIRP), low-grade glioma (LGG), pancreatic adenocarcinoma (PAAD), thymoma (THYM), testicular germ cell tumor (TGCT) and primary SKCM. This evidence concerns the gene STAT3 and testicular germ cell tumor.
