摘要: Inflammatory myofibroblastic tumor (IMT) is a distinctive mesenchymal neoplasm characterized by spindle-cell proliferation with an inflammatory infiltrate. Approximately half of IMTs carry rearrangements the anaplastic lymphoma kinase (ALK) locus on chromosome 2p23, causing aberrant ALK expression. We report sustained partial response to inhibitor crizotinib (PF-02341066, Pfizer) in patient ALK-translocated IMT, as compared no observed activity another without translocation. These results support dependence ALK-rearranged tumors ALK-mediated signaling and suggest therapeutic strategy for genomically identified patients aggressive form this soft-tissue tumor.
