Application of Third-generation TKIs in EGFR-mutated Non-small Cell Lung Cancer

The individualization of cancer treatment has brought about revolution in clinical practice. In recent years, EGFR-TKI has shown good anti-tumor activity in non-small cell lung cancer with EGFR positive mutation. Compared with the first-generation EGFR-TKI, the third-generation EGFR-TKI significantly increased the effective rate, progression-free survival and overall survival of advanced non-small cell lung cancer with EGFR mutation, especially the brain metastases. And the third-generation EGFR-TKI also showed the benefits of disease-free survival as the post-operative adjuvant therapy for operable EGFR-mutated non-small cell lung cancer. Moreover, the third-generation EGFR-TKI in combination with radiotherapy showed obvious advantages in the treatment of locally advanced and advanced oligometastatic EGFR-mutated non-small cell lung cancer.
