The Naples prognostic score (NPS), first described by Gennaro et al [23] as an independent prognostic factor in patients with colorectal cancer surgery, contains four nutritional and immune markers: serum albumin level, total cholesterol level, NLR, and LMR, and has been proved a good prognostic effect in gastrointestinal tumors [24]. Here, ALB is linked to colorectal cancer.
