Lung cancer is the second most common cancer worldwide. Non-small cell lung cancer (NSCLC) with anaplastic lymphoma kinase (ALK) gene rearrangements constitutes 3-5%. Crizotinib was approved for the first-line therapy of advanced ALK-positive NSCLC patients. We present a female patient with advanced ALK-positive NSCLC who was kept on crizotinib as first-line therapy and showed progression-free survival (PFS) of 48 months despite the data suggesting that the majority of patients on crizotinib show relapse within 1 year. Further studies should focus on the molecular and biological factors and the possible effect of the long-term use of this drug.
