A Case of ALK-Rearranged Adenocarcinoma with Small Cell Carcinoma-Like Transformation and Resistance to Crizotinib

J Thorac Oncol. 2016 May;11(5):e55-e58. doi: 10.1016/j.jtho.2015.12.097. Epub 2015 Dec 29.

Abstract

Histologic changes can be involved in resistance to anticancer drugs. Transformation to small cell lung carcinoma (SCLC) following treatment with EGFR tyrosine kinase inhibitors has been reported in patients with EGFR-mutant lung adenocarcinoma. Herein, we report a case of ALK-rearranged lung adenocarcinoma with SCLC-like histology in a metastatic abdominal nodule that was resistant to crizotinib therapy.

Keywords: Anaplastic lymphoma kinase; Crizotinib; Lung adenocarcinoma; Resistance; Small cell lung carcinoma.
