Here is a tweetorial from our latest publication in @Annals_Oncology about longitudinal tracking of esophageal adenocarcinoma. #OesophagealCancer #EsophagealCancer https://t.co/QWvrzBXmK7 1/8

We sequenced 245 plasma samples from 97 patients with oesophageal adenocarcinoma using a 77 gene pan-cancer ctDNA panel. 2/8
Variants derived from previously characterised driver oesophageal adenocarcinoma genes had a significantly higher VAF than variants from other genes, indicating selection. 3/8
Peripheral blood cell samples were also sequenced for 78/97 patients. CHIP mutations were identified in 23% of cases, longitudinal tracking of CHIP variants suggested these variants were dynamic over time. 4/8
We found patients that were ctDNA positive post-surgery had a significantly poorer survival than ctDNA negative patients, and the elimination of CHIP variants improved the positive predictive value. 5/8
In summary, we demonstrate in a large, national, prospectively-collected dataset that ctDNA in plasma following surgery for EAC is prognostic for relapse. Inclusion of peripheral blood cell samples can reduce or eliminate false positives from CHIP. 6/8
In the future, post-operative ctDNA could be used to risk stratify patients into high- and low-risk groups for intensification or de-escalation of adjuvant chemotherapy. 7/8
Many thanks to our founders and all patients who participated within the OCCAMS consortium framework. The study was carried out by our brilliant PhD student Emma Ococks, medical oncologist @LizzySmyth1, postdoc @AFrankell, and postdoc @neus_snows among others @MRC_CU. 8/8

THREAD: 12 Things Everyone Should Know About IQ

1. IQ is one of the most heritable psychological traits – that is, individual differences in IQ are strongly associated with individual differences in genes (at least in fairly typical modern environments). https://t.co/3XxzW9bxLE


2. The heritability of IQ *increases* from childhood to adulthood. Meanwhile, the effect of the shared environment largely fades away. In other words, when it comes to IQ, nature becomes more important as we get older, nurture less.

3. IQ scores have been increasing for the last century or so, a phenomenon known as the Flynn effect. https://t.co/sCZvCst3hw (N ≈ 4 million)

(Note that the Flynn effect shows that IQ isn't 100% genetic; it doesn't show that it's 100% environmental.)


4. IQ predicts many important real world outcomes.

For example, though far from perfect, IQ is the single-best predictor of job performance we have – much better than Emotional Intelligence, the Big Five, Grit, etc. https://t.co/rKUgKDAAVx https://t.co/DWbVI8QSU3


5. Higher IQ is associated with a lower risk of death from most causes, including cardiovascular disease, respiratory disease, most forms of cancer, homicide, suicide, and accident. https://t.co/PJjGNyeQRA (N = 728,160)
