In a huge NGS project including more than 10,000 patients with metastatic cancer across 62 principal solid tumor entities, the most commonly mutated genes were, in decreasing order of alteration frequency, TP53, KRAS, TERT, PIK3CA, APC, ARID1A, PTEN, EGFR, KMT2D, and RB1 [29]. This evidence concerns the gene EGFR and metastatic malignant neoplasm.
