The fibrinogen-to-albumin ratio (FAR) (14), the fibrinogen-to-prealbumin ratio (FPR) (15), the albumin-to-globulin ratio (AGR) (16), the advanced lung cancer inflammation index (ALI) (17), the prognostic nutritional index (PNI) (18), the albumin-to-alkaline phosphatase ratio (AAPR) (19), and the C-reactive protein-to-albumin ratio (CAR) (20), as well as other inflammatory and nutritional complex indicators, are also biomarkers for predicting the prognosis of lung cancer. This evidence concerns the gene TTR and lung cancer.
