Advances in DNA sequencing technologies have allowed the characterization of
somatic mutations in a large number of cancer genomes at an unprecedented level
of detail, revealing the extreme genetic heterogeneity of cancer at two different
levels: inter-tumor, with different patients of the same cancer type presenting
different collections of somatic mutations, and intra-tumor, with different
clones coexisting within the same tumor. Both inter-tumor and intra-tumor
heterogeneity have crucial implications for clinical practices. Here, we review
computational methods that use somatic alterations measured through
next-generation DNA sequencing technologies for characterizing tumor
heterogeneity and its association with clinical variables. We first review
computational methods for studying inter-tumor heterogeneity, focusing on methods
that attempt to summarize cancer heterogeneity by discovering pathways that are
commonly mutated across different patients of the same cancer type. We then
review computational methods for characterizing intra-tumor heterogeneity using
information from bulk sequencing data or from single cell sequencing data.
Finally, we present some of the recent computational methodologies that have been
proposed to identify and assess the association between inter- or intra-tumor
heterogeneity with clinical variables.
