Complete Response After Ceritinib Treatment In Non-Small Cell Lung Cancer In An Elderly Patient

IntroductionCeritinib is a selective second-generation ALK inhibitor that is highly sensitive to echinoderm microtubule-associated protein-like 4-anaplastic lymphoma kinase (EML4-ALK) molecule.Case reportIn this paper, we report a 68-year-old female that was diagnosed with stage 4 ALK-positive non-small cell lung cancer (NSCLC).Management and outcome: She was treated with crizotinib first-line, cisplatin and gemcitabine as second-line. And for third-line, ceritinib was started. She had complete response over 3.5 years under ceritinib treatment. And she is still receiving ceritinib with no adverse event.DiscussionCases achieving complete response with ceritinib treatment are rare. In this paper, we aimed to emphasize the complete response in stage 4 NSCLC in an elderly patient.
