Discrimination between the neurofibromatosis type 1 (NF1) group and control group receiver operating characteristic (ROC) curves. (A) interleukin (IL)-6, (B) interferon (IFN)-γ, (C) tumor necrosis factor (TNF)-α and (D) epidermal growth factor receptor (EGFR). The ROC curves for discrimination between patients with NF1 with and without malignant peripheral nerve-sheath tumors (MPNST) are shown in (E) for insulin-like growth factor binding protein (IGFBP)1 and (F) for Regulated upon activation, normal T-cell expressed and secreted (RANTES).
