Abstract:

Background: Uncommon mutations account for 10% to 15% of Epidermal Growth Factor Receptor (EGFR) mutations in patients with Non-Small Cell Lung Cancer (NSCLC). However, limited clinical evidence is available on the efficacy of EGFR tyrosine kinase inhibitors in patients with NSCLC harboring these uncommon EGFR mutations. Case Report: Here we report a 74-year-old man was diagnosed with stage IV lung adenocarcinoma by bronchoscopic biopsy to the left principal bronchus lung tumor. A novel EGFR p.G735R (c.2203G>C) mutation in exon 19 was detected by gene sequencing. The patient received first-line Gefitinib but primary resistance was noted with rapid tumor progression. Conclusion: Our case suggests that G735R may be one of the EGFRTKI primary resistant rare EGFR mutations.
