Controlling nutritional status (CONUT) is calculated from serum albumin (Alb), total cholesterol (TC), and peripheral lymphocyte count (TLC) [10], which relate to a variety of nutritional indicators that can enable quick assessment of nutritional status and allow the prognosis of NSCLC patients to be accurately predicted [11–13]. The gene discussed is ALB; the disease is non-small cell lung carcinoma.
