Lung cancer remains the leading cause of cancer death world-wide. This is in part due patients presenting late with disseminated disease and despite recent advances, a limited therapeutic landscape... Despite these advances there remains a significant unmet clinical need with much research needed to elucidate the optimal treatment paradigm to improve response rates, mortality and quality of life for patients with advanced NSCLC.

Anaplastic lymphoma kinase (ALK)-rearranged non-small cell lung cancer (NSCLC) treated with ALK tyrosine kinase inhibitor (TKI) eventually acquires resistance to the treatment. However, our current knowledge regarding the resistance mechanisms is based on non-synonymous mutation and amplification in ALK, with the reasons still unknown for nearly half of all such cases. Other than genomic alteration as a resistance mechanism, up to 10% of NSCLC with activating epithelial growth factor receptor (EGFR) mutation showed resistance to EGFR TKI through histologic transformation. Although limited in number, there are cases showing transformed samples retaining the initial genomic alteration, which support lineage transition as a novel resistance mechanism. In this report, we described the first case of squamous cell carcinoma (SCC) transformation from adenocarcinoma (ADC) in NSCLC with ALK rearrangement after treatment with ALK TKI. READ ARTICLE
