RESUMEN
To explore the presentation and control of CNS adverse reactions in patients with ALK-positive NSCLC treated with lorlatinib. This study includes a retrospective case report from Sir Run Run Shaw Hospital on a lorlatinib-treated patient with CNS adverse reactions and a systematic literature review of similar cases until January 2023. The report detailed a case of a 74-year-old male with Grade III CNS adverse reactions 25 days after starting lorlatinib, which were reversible with dose modification and pharmacotherapy. The review indicated a 19.39% occurrence rate of such reactions, with a 17% improvement rate post-dose adjustment. CNS adverse reactions frequently occur in ALK-positive NSCLC patients on lorlatinib, yet they are reversible with appropriate management. Research should continue to optimize treatment protocols to decrease these reactions' frequency.
