FIGURE 1. Positron emission tomography-computed tomography scan demonstrating metabolic complete remission with erlotinib. Journal of Thoracic Oncology 2011 6, 1962-1963DOI: (10.1097/JTO.0b013e31822eec5e) Copyright © 2011 International Association for the Study of Lung Cancer Terms and Conditions
FIGURE 2. A, Three tumor nuclei assessed for ALK rearrangements by fluorescence in situ hybridization (FISH), demonstrating isolated red (3′) signals in addition to multiple paired red/green signals. FISH was considered positive as abnormal signal was observed in at least 15% of cells with at least 50 cells counted. B, Acinar pattern adenocarcinoma negative for ALK expression by immunohistochemistry.
