Known lung cancer genes (EGFR, KRAS G12C, ALK, MET, RET) were found in 33 patients; 11 had genes relevant to both lung and other cancers (ERBB2, BRAF V600, NTRK), and 37 had genes typically linked to other malignancies (NF1, PIK3CA, PALB2, FGFR2B, FBX7, RAD51). This evidence concerns the gene PIK3CA and lung carcinoma.
