Neoadjuvant Lazertinib Therapy in EGFR-Mutation Positive Lung Adenocarcinoma Detected by BALF Liquid Biopsy

Официальное название

A Phase II, Single-Center, Single-Arm, Prospective Study of Neoadjuvant Lazertinib Therapy in Resectable EGFR-Mutation Positive Lung Adenocarcinoma Patients Detected by Broncho-alveolar Lavage Fluid(BALF) Liquid Biopsy

Обзор

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.

Подробное описание

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.
