Molecular subtypes of small cell lung cancer characterized by neuroendocrine differentiation have been described in cell lines and primary tumors. The clinical implications of neuroendocrine subtypes in metastatic and relapsed tumors, and the extent to which the subtype distribution is recapitulated in patient-derived models remains unclear. Here, the authors integrated genomics and transcriptomics on 100 small cell cancers from a range of metastatic sites finding complex intra- and intertumoral heterogeneity, notably not recapitulated in patient-derived model systems, and distinct therapeutic vulnerabilities associated with neuroendocrine subtypes.
