Measurements of subclonal expansion of ctDNA in the plasma before surgery may enable the prediction of future metastatic subclones, offering the possibility for early intervention in patients with non-small-cell lung cancer.

Computational and machine-learning approaches that integrate genomic and transcriptomic variation from paired primary and metastatic non-small cell lung cancer samples from the TRACERx cohort reveal the role of transcriptional events in tumour evolution.

An analysis of whole-genome sequencing data from patients with Barrett’s oesophagus or oesophageal ademocarcinoma shows that extrachromosomal DNA (ecDNA) is strongly associated with cancer progression, and that a wide range of oncogenes are amplified on ecDNAs.

A study shows that clonal haematopoiesis of indeterminate potential is associated with an increased risk of chronic liver disease specifically through the promotion of liver inflammation and injury.

Epstein–Barr Virus (EBV) nuclear antigen 1 is shown to induce breakage of a fragile site on chromosome 11 by binding to a cluster of EBV-like imperfect palindromic repeats.
