Therefore, in recent years, some prognostic markers based on inflammation and nutrition have been introduced, including Glasgow Prognostic Score (GPS) (7), Modified Glasgow prognosis score (MGPS) (8), C-reactive protein-albumin ratio (CRP/ALB, CAR) (9), Prognostic nutrition index (PNI) (10, 11) and advanced lung cancer inflammation index (ALI) (12, 13) to predict the prognosis and survival of patients with lung cancer. The gene discussed is CRP; the disease is lung cancer.
