[Research Progress in the Treatment of Brain Metastases from Non-small Cell Lung Cancer].

Lung cancer is the leading cause of cancer-related deaths worldwide. The most common pathological type of lung cancer is non-small cell lung cancer (NSCLC). The incidence of brain metastases caused by NSCLC has been on the rise. Brain metastasis seriously affects the patient's cognitive function, survival time and quality of life, and the prognosis is extremely poor. The natural course of the disease is about 1 mon-3 mon. After treatment, the median survival time is only 3 mon-6 mon, the one year survival rate is 14%, and the two years survival rate is only 7.6%. The location, number, and size of brain metastases are related to their symptoms and survival. Patients with central nervous system symptoms have a worse prognosis. The goal of brain metastasis treatment is to optimize overall survival and quality of life, and to prioritize the preservation of neurocognitive functions. At present, the main treatments for brain metastases in NSCLC include radiotherapy, surgery, chemotherapy, molecular targeting, and immunotherapy. Clinically, it is necessary to conduct a multidisciplinary assessment of the best treatment methods for patients according to the heterogeneity of patients (clinical characteristics, pathological types, tissue types, etc). This article aims to review the research progress of current treatment methods.
