The appearance of a brain metastasis is generally regarded as an ominous event in the progression of many solid tumors because it usually means that the patient will have reduced quality and length of survival. It is important to study the biology of brain metastasis because present treatments are principally palliative and new approaches to diagnosis and treatment are clearly needed.
在许多实体瘤的进展过程中，脑转移瘤的出现通常被视为一个不祥之兆，因为这通常意味着患者的生存质量和生存期将会降低。研究脑转移瘤的生物学特性很重要，因为目前的治疗主要是姑息性的，显然需要新的诊断和治疗方法。
