For example, the expression of VEGF was low in papillary fibroelastoma and lipoma without neovascularization (0%–7.0%), while the lowest malignant tumor was 14.1% (osteosarcoma), and the highest malignant tumor was 94.4% (undifferentiated sarcoma of adrenal gland). This evidence concerns the gene VEGFA and osteosarcoma.
