About

Complete surgical resection is the standard treatment in early-stage lung cancer. However, the patients with early resected Epidermal Growth Factor Receptor(EGFR)-mutated lung cancers have high recurrence rate. The efficacy of neoadjuvant treatment by first-generation EGFR-Tyrosine Kinase Inhibitor(TKI) has been demonstrated, however, that of the third-generation EGFR-TKI(lazertinib) has not yet been fully investigated. The aim of this study is to evaluate the efficacy of neoadjuvant Lazertinib in resectable EGFR mutation-positive NSCLC and clinical application of extracellular vesicles(EVs) based BALF liquid biopsy to identify EGFR mutation without invasive tissue biopsy.

Full description

The neoadjuvant treatment of 3rd-generation EGFR-TKI, lazertinib for 9 weeks before surgery is administrated. After the surgery, the patients with the tumor over stage 2 are given the lazertinib to prevent recurrence for 3 years or until recurrence. In early lung cancer, a tissue biopsy is often difficult due to the small size or the risky location. We collect bronchoalveolar lavage fluid for liquid biopsy and lazertinib is administrated according to the result of BALF liquid EGFR genotyping.

  4. Patients whose tumor can be completely resected by surgery: patients with stage I-IIIB, or stage IVA who has single metastasis
  5. Patients not previously treated with EGFR-TKIs such as gefitinib, erlotinib, afatinib, dacomitinib
  6. Patients with the measurable lesion of 1 cm or more according to RECIST v1.1
  7. Eastern Cooperative Oncology Group (ECOG) 0-1
  8. EGFR-TKIs (gefitinib, erlotinib, afatinib,dacomitinib) naive patients

  5. Gastrointestinal diseases (e.g. Chron's disease, ulcerative colitis) or malabsorption syndrome that would impact on drug absorption
  6. Active infection requiring ongoing treatment(e.g. active Hepatitis B virus, Hepatitis C virus or Human immunodeficiency virus)
  7. History of hypersensitivity to active or inactive excipients of Lazertinib or drugs with a similar chemical structure.
