A nomogram for predicting brain metastasis of EGFR-mutated LUAD patients and estimating the efficacy of therapeutic strategies was constructed by Wang et al. (2021) Similarly, a nomogram model was designed by Wang et al. (2022a) based on easily accessible clinical factors which demonstrated excellent performance to predict the individual cancer-specific survival of NSCLC patients with liver metastasis. This evidence concerns the gene EGFR and non-small cell lung carcinoma.
