However, other studies (n = 189–1063) evaluating the incidence of bone metastases in different molecular subgroups, i.e., EGFR-mutated, KRAS-mutated, ALK-rearranged or wildtype patients with non-squamous NSCLC, showed conflicting results [8,10,11,12,13]. Here, EGFR is linked to non-small cell lung carcinoma.
