ALB and lung cancer: Some of these indexes have been largely described in this paper; for example, albumin and neutrophil-to-lymphocyte ratio (NLR), have been shown to be able to predict the efficacy of ICI therapy in cancer patients [71,72]; the advanced lung cancer inflammation index (ALI), including albumin, NLR, and BMI, might help to predict survival outcomes in various tumors [73,74].
