Figure 5From: Concomitant occurrence of EGFR (epidermal growth factor receptor) and KRAS (V-Ki-ras2 Kirsten rat sarcoma viral oncogene homolog) mutations in an ALK (anaplastic lymphoma kinase)-positive lung adenocarcinoma patient with acquired resistance to crizotinib: a case reportEpidermal growth factor receptor mutation analysis by Sanger sequencing. A: Epidermal growth factor receptor wild type codon 862 (L862) in inguinal lymph node metastasis before starting crizotinib treatment B: Epidermal growth factor receptor mutation in codon 862 (c.2585 T > G; p.L862R) in newly appeared inguinal lymph nodal metastasis after 8 months of crizotinib treatment.Back to article page
