Firstly, the univariate logistic analysis showed that age, adenocarcinoma, gene mutation, metastasis, antitumor therapy, WBC, HB, PLT, CRP, NLR, PLR, LMR, SII, hypoproteinemia (Albumin <40 g/L), and D-dimer were correlated with VTE in lung cancer patients. The gene discussed is CRP; the disease is lung carcinoma.
