Our paper describing the use of an ultrasensitive circulating tumour DNA detection assay to stratify #TRACERx patients with early-stage non-small cell lung cancer pre-operatively for clinical outcome is out today @NatureMedicine. Thread below 👇
ctDNA is an established biomarker for high-risk disease before and after surgical resection in NSCLC. We tested NeXT Personal, an assay from @PersonalisInc able to detect ctDNA at extremely low levels, to understand whether ultra-sensitive approaches provide added value here.

🔬Circulating tumor DNA is a powerful biomarker that can guide and monitor treatment response in early-stage lung cancer patients. Technologies enabling ctDNA detection and characterization are advancing rapidly but we need to understand how to use them in the clinic…
A quick thread [1/13]
We analysed paired primary-metastasis data from 126 patients (218 metastatic & 476 primary tumour samples) within the first 421 patients recruited to TRACERx. We explored the timing of metastatic divergence, modes of metastatic dissemination and selection in seeding clones [2/13]

Today our important study on air pollutants in the promotion of lung cancer has been published in @Nature led by @WillHilliam@LimEmilia@DrClareWeeden@SwantonLab ...Thread below🧵nature.com/articles/s4158…
Air pollution is linked with 7 million premature deaths annually and is associated with heart disease, cancer and dementia. The vast majority of people live in places where air pollution levels exceed @WHO guidelines

1/24 - Can we decipher order from cancer genomes? Our new paper “Pervasive chromosomal instability and karyotype order in tumour evolution” comes out in Nature today: nature.com/articles/s4158…@BCRFcure@TheCrick@CRUKresearch@RosetreesT@uclcancer@SwantonLab@royalsociety
2/24 - Chromosomal instability (CIN) is common in cancer and consists of dynamic changes in chromosome number and structure. This instability can result in somatic copy number alterations - SCNAs - which may provide a substrate for tumour evolution.
