Non-small cell lung cancer (NSCLC) is one of the malignant tumors with the highest incidence of brain metastases. Patients with multiple brain metastasis showed poor prognosis and displayed an untreated median survival of only 3-6 months, and most patients died due to the progression of brain metastases. This study is designed to evaluate the safety and efficacy of icotinib combined with whole brain radiotherapy for NSCLC patients with brain metastases. The primary endpoint is intracranial objective response rate .
The purpose of this study is to evaluate the safety and efficacy of icotinib in combination with whole brain radiotherapy for NSCLC patients with brain metastases. The primary endpoint is objective response rate of intracranial lesions.
