As a result, EGFR mutations were identified in thirteen (81%, 13/16) of sixteen tumor tissue samples, which included eight (61%, 8/13) samples carrying a single EGFR p.L858R mutation, three (23%, 3/13) samples containing a single EGFR exon 19 deletion, and one (8%, 1/13) sample harboring a single EGFR p.L861Q mutation. Here, EGFR is linked to neoplasm.
