First-line alectinib significantly improved intracranial and systemic outcomes in ALK-positive non-small cell lung cancer patients with brain metastases compared to ceritinib. Ceritinib with upfront brain radiotherapy is a viable option in resource-limited settings.
Area of Science:
- Oncology
- Pharmacology
- Clinical Trials
Background:
- Comparing first-line alectinib and ceritinib efficacy in ALK-positive non-small cell lung cancer (NSCLC) with brain metastases (BM).
- Evaluating the role of upfront brain radiotherapy (RT) in this patient population.
Purpose of the Study:
- To compare the efficacy of first-line alectinib versus ceritinib in ALK-positive NSCLC patients with BM.
- To assess the impact of upfront brain radiotherapy in conjunction with these treatments.
Main Methods:
- Retrospective analysis of 108 ALK-positive NSCLC patients with baseline BM treated with alectinib or ceritinib.
- Assessment of intracranial and systemic responses using RANO-BM and RECIST v1.1 criteria.
- Survival outcomes analyzed via Kaplan-Meier and multivariable Cox regression.
Main Results:
- Alectinib showed superior intracranial disease control (iDCR 97.6% vs. 83.3%) and longer median intracranial progression-free survival (iPFS 40.4 vs. 17.2 months) compared to ceritinib.
- Alectinib also demonstrated significantly longer systemic progression-free survival (PFS 35.9 vs. 11.5 months).
- Multivariable analysis confirmed alectinib as an independent predictor of better iPFS and systemic PFS.
Conclusions:
- First-line alectinib offers superior intracranial and systemic efficacy over ceritinib in a real-world Vietnamese cohort.
- Ceritinib combined with upfront brain RT presents a reasonable alternative in resource-limited settings.
- The potential differential benefit of brain RT between alectinib and ceritinib warrants further investigation.
