摘要
MRI在脑转移瘤的诊断、治疗以及随访中有重要作用。原发灶状况、脑转移瘤的体积、立体定向放疗前后是否加全脑放疗、一般状况评分、回归分割分析(RPA)分级、是否存在颅外转移等是影响脑转移瘤治疗效果的主要因素。单纯立体定向放疗逐渐成为脑转移瘤治疗的主流,分次立体定向放疗在脑转移瘤治疗中的作用尚未完全明确。
MRI has an important role in diagnosis, treatment and followed up for patients with brain metastases. The volume of metastases, state of the primary disease, kps, extracranial metastases, recursive partitioning analysis (RPA) class, adjuvant whole brain radiation therapy(WBRT) were the most importance factors associated with the effect of stereotactic radiotherapy. Treatment of brain metastases using stereotactic radiosurgery alone will to be the mainstay of management for patients with brain metastases. The value of fraction stereotactic radiotherapy in treatment brain metastases was not confirmed.
