Transformation of EML4-ALK fusion-positive adenocarcinoma into squamous cell carcinoma in association with acquired resistance to crizotinib

The development of targeted therapies has revolutionized the treatment of patients with lung cancer, especially non-small-cell lung cancer (NSCLC). Anaplastic lymphoma kinase (ALK) is a research hotspot of molecular targeted therapy for lung cancer. ALK tyrosine kinase inhibitors (TKIs) are highly effective for ALK-rearranged NSCLC-positive patients. These targeted therapies have significant clinical effects; however, they inevitably lead to acquired resistance. In previous studies, the histological transformation after ALK inhibitor treatment was mostly based on small-cell lung cancer (SCLC).
