Determinants of SCLC metabolism. The metabolism of SCLC cells is regulated not only by the so-called cell-intrinsic factors, such as genetic background and activated signaling pathways, but also by several other factors that include molecular subtype, metabolic phenotype, tumor microenvironment, intratumoral heterogeneity, and spatiotemporal evolution [79]. Interactions between more or all determinants can be present in the tumor as it is indicated by arrows on the rim of the figure (it cannot be accurately visualized in a 2D figure, but interactions among non-adjacent factors can also be present at the same time)
