Similar to cancer of the breast, lung and ovary, TF is also expressed at high percentages in many other human solid cancers (Table 1) [16,49], for instance, 95% in primary melanoma and 100% in metastatic melanoma, 53%–90% in pancreatic cancer, 57%–100% in colorectal cancer, 63%–100% in hepatocellular carcinoma, 60%–78% in primary and metastatic prostate cancer and 47%–75% in glioma. This evidence concerns the gene TF and melanoma.
