Nomogram predicting survival in elderly patients with NSCLC was constructed and validated by using R software.<h4>Results</h4>Statistically significant differences in age, gender, body mass index (BMI), histological type, albumin, treatment methods, neutrophil to lymphocyte ratio (NLR), prognostic nutritional index (PNI), systemic immune-inflammation index (SII) and cytokeratin 19 fragment (CYFRA21-1) were observed between the high and low GNRI groups (P<0.05). This evidence concerns the gene KRT19 and non-small cell lung carcinoma.
