    Title:

    P45.14 - Real-World Experience on Treatment of crizotinib in ALK/ROS1/MET Alterated Non-Small-Cell Lung Cancer Patients in China

    Published date:
    08/18/2021
    Excerpt:
    A total of 55 patients were included in the study, of which 36 with ALK fusion, and 13 with ROS1 fusion....the ORR of crizotinib was 53% with a median PFS of 12 months (range: 1–102 months)...confirmed the therapeutic benefit of crizotinib in ALK/ROS-1fusion-positive advanced NSCLC, and also in NSCLC with MET ex14 mutation. Our data showed crizotinib is tolerable and effective, which is comparable with literature report.

    Excerpt:
    The median PFS was 5.2 months, and median OS was 12.7 months….Our study highlighted and confirmed the efficacy of crizotinib in patients with NSCLC with ROS1 or MET genetic alterations. Crizotinib had remarkable effects on advanced NSCLC with ROS1 fusion, as previously reported.

    Crizotinib presented with promising efficacy but for concomitant mutation in next-generation sequencing-identified ROS1-rearranged non-small-cell lung cancer

    Published date:
    10/15/2018
    Excerpt:
    Among 22 patients with ROS1-rearranged NSCLC, 20 patients were diagnosed at stage IV, and 19 patients received crizotinib treatment....It was shown that NSCLC patients with exclusive ROS1 rearrangement had a longer PFS than those carrying concomitant mutations (15.5 vs 8.5 months, P=0.0213).
