Objective The aim of this study was to define the maximum-tolerated dose (MTD) and observe the toxicity of escalating topotecan combined whole brain radiotherapy for brain metastasis in lung cancer.

The prognosis of non-small-cell lung cancer(NSCLC) patients with brain metastasis is generally poor and more effective treatment is required to improve their prognosis. Whole-brain radiotherapy, surgery, stereotactic radiosurgery, chemotherapy and targeted therapy are the main treatment for brain metastasis. This review focuses on the five therapeutic strategy and in particular, on targeted therapy.展开更多
