The clinical features and imaging findings of different tumor radiotherapy for brain metastasis of lung cancer after the recent time window and the standard of curative effect evaluation Professional: Oncology Graduate student: Liu Yufeng Supervisor: Professor Lu Bing [Abstract] Objective: To retrospectively analyze the clinical and imaging features of brain metastases from lung cancer, and to investigate the time window and standard of the treatment for the treatment of cystic metastases. Methods: 289 patients with brain metastasis from brain MRI were diagnosed by brain metastasis, and the correlation of number, size, and pathological types of brain metastases were analyzed.. Evaluation of 214 cases of complete intracranial lesions with radiotherapy and radiotherapy rechecked MRI data of patients with curative effect in the near future, to compare the 95 patients with clinical manifestations of nervous system were improved in the recent curative effect, and put forward more in line with the clinical characteristics of metastatic brain tumor evaluation method. Results: isolated metastatic lesions, cystic imaging performance were common in squamous cell carcinoma; non squamous cell carcinoma is to is more than or equal to 2 metastatic lesions and imaging signs seen; small cell lung cancer is more than or equal to two metastatic lesions, cystic imaging signs see more (P=0.008,P=0.027).The main distribution of metastasis foci in three case types was 10-30mm size. Tumor cystic and solid tumor in similar radiation and dose conditions, afte
