Phase III Study of Icotinib Treat the Patient With Brain Metastasis EGFR-mutant Non Small Cell Lung Cancer Comparing With Whole Brain Radiotherapy
Phase III Study of Icotinib Treat the Patient With Brain Metastasis EGFR-mutant Non Small Cell Lung Cancer Comparing With Whole Brain Radiotherapy
EGFR-TKI is good for the patients with EGFR-mutant non-small cell lung cancer.We design this clinical trail to confirm if the efficacy of Epidermal Growth Factor Receptor Tyrosine Kinase Inhibitor(EGFR-TKI )(ICOTINIB) is better than whole brain irradiation for the patient with EGFR-mutant non-small cell lung cancer.
