We report two inflammatory myofibroblastic tumor (IMT) patients with ALK fusions (RRBP-ALK and TNS1-ALK, respectively). They both received tumor resection surgery and treatment with ALK inhibitors crizotinib followed by
[Paragraph-level] PMCID: PMC7568619 Section: ABSTRACT PassageIndex: 2
Evidence Type(s): Predictive, Oncogenic
Justification: Predictive: The variant L1196Q is associated with the development of resistance to ALK inhibitors, and its identification guided the prescription of a newer ALK inhibitor, ceritinib, which resulted in a partial response in the patient. Oncogenic: The passage indicates that the L1196Q mutation is a secondary mutation that developed in the context of drug resistance, suggesting it contributes to tumor progression and the development of resistance to therapy.
