Multivariate modeling was also performed using six parameters (platelet count, mean platelet volume (MPV), and concentrations of VEGF, PDGF, PF4, CTAPIII, and TSP-1 in platelets and platelet-free plasma (PFP)), and AUC was 0.868 for the diagnosis of lung cancer. The gene discussed is VEGFA; the disease is lung carcinoma.
