Abstract

During oncogenesis, cells acquire multiple genetic alterations that confer essential tumor-specific traits, including immortalization, escape from antimitogenic signaling, neovascularization, invasiveness, and metastatic potential. In most instances, these alterations are thought to arise incrementally over years, if not decades. However, recent progress in sequencing cancer genomes has begun to challenge this paradigm, because a radically different phenomenon, termed chromothripsis, has been suggested to cause complex intra- and interchromosomal rearrangements on short timescales. In this Review, we review established pathways crucial for genome integrity and discuss how their dysfunction could precipitate widespread chromosome breakage and rearrangement in the course of malignancy.
