TL;DR: Intratumor heterogeneity can lead to underestimation of the tumor genomics landscape portrayed from single tumor-biopsy samples and may present major challenges to personalized-medicine and biomarker development.

TL;DR: It is shown that phylogenetic ct DNA profiling tracks the subclonal nature of lung cancer relapse and metastasis, providing a new approach for ctDNA-driven therapeutic studies.

TL;DR: 25 spatially distinct regions from seven operable NSCLCs were sequenced and found evidence of branched evolution, with driver mutations arising before and after subclonal diversification, and pronounced intratumor heterogeneity in copy number alterations, translocations, and mutations associated with APOBEC cytidine deaminase activity.

TL;DR: Evidence for impaired replication fork progression and increased DNA replication stress in CIN+ colorectal cancer (CRC) cells relative to CIN− CRC cells is found, with structural chromosome abnormalities precipitating chromosome missegregation in mitosis.
