Purpose: The performance of alectinib and crizotinib in untreated anaplastic lymphoma kinase (ALK)-positive patients with non-small-cell lung cancer (NSCLC) and symptomatic and synchronic brain metastases is largely unknown. This retrospective study assessed the effectiveness of alectinib and crizotinib, together with intracranial therapies in a cohort of these patients.
Patients and Methods: This study included 34 previously untreated ALK-positive NSCLC patients with three or fewer intracranial metastases. Of these patients, 13 received oral alectinib 600 mg twice daily, and 21 received oral crizotinib 250 mg twice daily, until progressive disease, unacceptable toxicity, or death. All intracranial metastases were treated with craniotomy, CyberKnife, or both.
Results: Median overall progression-free survival (PFS) was 32.8 months (95% CI 24.4– 41.2 months) in patients treated with alectinib and 8.0 months (95% CI 7.3– 8.7 months) in patients treated with crizotinib. Median PFS of brain..... READ ARTICLE
