Ding et al [19] identified age (P = .013), BMI (P = .001), anemia (P = .005), pre-albumin (P = .010), albumin (P = .002), tumor location (P = .001), and tumor size (P = .002) as risk factors for malnutrition in patients with GI stromal tumors. This evidence concerns the gene ALB and anemia (phenotype).
