摘要:

脑转移在间变性淋巴瘤激酶(ALK)阳性非小细胞肺癌(NSCLC)患者中较常见,第一代至第三代ALK-酪氨酸激酶抑制剂(TKI)已广泛应用于ALK阳性脑转移的治疗,但仍有部分患者颅内控制不佳。一代ALK-TKI不能透过血脑屏障,联合颅脑放疗可显著改善颅内控制;二、三代ALK-TKI可透过血脑屏障,具有更好的颅内控制,联合放疗的获益人群及介入时机仍存在争议。ALK-TKI联合颅脑放疗的方式目前尚无定论,但应结合患者既往放疗史、靶向药物种类、脑转移灶数量、ALK-TKI间隔时间等综合考虑,并需密切监测脑坏死等放疗相关不良反应。

Abstract:

Brain metastases are relatively common in anaplastic lymphoma kinase (ALK)-positive non-small cell lung cancer (NSCLC) patients. Although first-to third-generation ALK-tyrosine kinase inhibitors (TKI) have been widely used in the treatment of ALK-positive patients with brain metastases, some patients still experience inadequate intracranial control. First-generation ALK-TKI cannot penetrate the blood-brain barrier, and the addition of brain radiotherapy significantly improves intracranial control. In contrast, second- and third-generation ALK-TKI can cross the blood-brain barrier, offering better intracranial control. However, the beneficiary population and optimal timing for combining radiotherapy remain controversial. The optimal approach for combining ALK-TKI with cranial radiotherapy remains inconclusive. It should be determined by comprehensively considering factors such as prior radiotherapy history, the type of targeted drugs, the number of brain metastases, the interval time of ALK-TKI, and others. Close monitoring for radiotherapy-related adverse effects, such as brain necrosis, is also essential.
