Abstract
Various mechanisms of resistance to ALK inhibitors in ALK rearranged adenocarcinomas are reported including secondary gatekeeper mutations, bypass signaling or ALK amplifications as the commonest ones. We report a new mechanism of resistance with transformation of adenocarcinoma into small cell lung cancer. A 53-year-old non-smoker woman, experienced cancer progression after two lines of ALK inhibitors. A new biopsy showed a small cell lung cancer. FISH revealed persistent ALK rearrangement with an atypical pattern and complete loss of the 5' region of the ALK gene.Entities:
