AbstractSmall cell lung cancer (SCLC) is characterised by an aggressive clinical course with invariable resistance to chemotherapy despite initially high response rates. There has been little improvement in outcome over the past few decades, with no breakthrough yet in targeted therapies. Recent preclinical data and studies of circulating tumour cells (CTCs) highlight distinct cellular heterogeneity within SCLC. Better understanding of how these phenotypes contribute to metastasis and tumour progression might pave the way for development of more successful targeted therapies. Here we review these studies, their implications for future research and for the incorporation of biomarkers reflecting neuroendocrine, epithelial and mesenchymal phenotypes in clinical studies.
