Multiple nutritional assessment systems, including Naples Prognostic Score (NPS), Nutritional Risk Screening (NRS), body mass index (BMI), albumin (ALB), and prognostic nutritional index (PNI), have emerged with the aim of detecting and predicting the clinical outcomes of gastric cancer patients (Li et al., 2019; Wu et al., 2019; Bae, 2020; Park et al., 2020; Xiong et al., 2020). The gene discussed is ALB; the disease is gastric cancer.
