Brain metastases are an important cause of morbidity and mortality, and are the most common intracranial tumors in adults. The prognosis of patients with brain metastases is very poor. The increasing incidence of brain metastases is directly related to the improvements in the treatment of systemic disease. Commonly, brain metastases are discovered after the diagnosis of cancer, often after other systemic metastases have developed. In this review article, we present the standard treatment approach and discuss new directions.
The most widely used treatment for patients with brain metastases is whole-brain radiotherapy. Actually, surgery and radiotherapy remain the principal therapeutic interventions. In contrast, the benefit of chemotherapy has long been viewed with skepticism.In an effort to improve the therapeutic ratio, radiosensitizers are often used concurrently with external-beam radiation: motexafin gadolinium and efaproxaril.Novel anticancer agents are under clinical investigation.
The management of patients with brain metastases with non-small cell lung cancer has improved over time, due to the development of new treatment options and a better knowledge of prognostic factors.In the next 5 years, the results of several ongoing multicenter randomized trials will become available to further define the role of various radiation sensitizers and chemotherapeutic agents in combination with stereotactic radiosurgery, whole-brain radiation therapy, or both.
脑转移是发病率和死亡率的重要原因,也是成年人中最常见的颅内肿瘤。脑转移患者的预后非常差。脑转移发生率的增加与全身疾病治疗的改善直接相关。通常,脑转移在癌症诊断后被发现,通常在其他全身转移发生后。在这篇综述文章中,我们提出了标准的治疗方法,并讨论了新的方向。
脑转移患者最广泛使用的治疗方法是全脑放疗。实际上,手术和放疗仍然是主要的治疗干预措施。相比之下,化疗的益处长期以来一直受到怀疑。为了提高治疗比率,放射增敏剂经常与外照射同时使用:莫替沙芬钆和 efaproxaril。新型抗癌药物正在进行临床研究。
随着新的治疗选择和更好的预后因素的出现,非小细胞肺癌脑转移患者的治疗得到了改善。在未来 5 年内,几项正在进行的多中心随机试验的结果将提供进一步确定各种放射增敏剂和化疗药物与立体定向放射外科、全脑放疗或两者联合应用的作用。
