There is a pressing need to expand treatment options for patients with SCLC, which requires a better understanding of the mechanisms by which this disease is able to rapidly grow and evolve in response to therapy. Our current understanding points to epigenetic rather than genetic factors in defining major aspects of inter- and intra-tumoral heterogeneity in SCLC. SCLC is overall considered to be a neuroendocrine (NE) cancer type but SCLC tumors harbor a wide diversity of cancer cell states, including both NE and non-neuroendocrine (non-NE) states, defined by their mutually exclusive expression of a set of transcription factors such as ASCL1, NEUROD1, and POU2F3. The immune microenvironments of SCLC tumors also contain a great deal of heterogeneity.
