Excited to share our TRACERx nature publication on circulating tumor DNA (#ctDNA, #MRD) detection in resectable lung cancer led by @AbboshChris, @AFrankell, @juditkisistok, Thomas Harrison, Aaron Garnett, @nbirkbak and @NickyMcGranahan 👇👇👇 Tweetorial🧵

🔬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…
👥 Through collaboration with scientists at @TheCrick and @uclcancer, @AstraZeneca and @Invitae, we developed and validated an anchored-multiplex PCR approach ctDNA detection in 197 patients who donated over 1000 plasma samples to TRACERx.

Endocrine treatment is among the most effective treatment strategies we have for breast cancer. 50 years ago, the approval of the SERD tamoxifen really revolutionized the field, & we still use the drug today.
Yet, no novel ET had been approved for the last 20 years. Until now

Multiple oral SERDs (selective estrogen receptor degraders) are being developed for patients with HR+ MBC. The first to achieve positive phase 3 results was elacestrant, tested in the #EMERALD trial vs. SoC ET (fulvestrant or AI). Primary endpoint -> PFS overall & in ESR1-mut

I would like to do my 2nd deep dive post #ASCO22 analysis on #ctDNA guided adjuvant therapy for pts with stage II colon cancer‼️
✳️The DYNAMIC trial is certainly step forward (kudos) ‼️But doesn’t answer many questions❗️@OncoAlert @manjuggm @CrcChange @TheColonClub Why ?👇
✳️The DYNAMIC trial is certainly step forward (kudos) ‼️But doesn’t answer many questions❗️@OncoAlert @manjuggm @CrcChange @TheColonClub Why ?👇
1️⃣ Firstly, the whole point of ctDNA is identification of MRD so to give RIGHT chemotherapy to RIGHT patients❗️
✳️Not only reduce adjuvant tx, but offer it to patients who may potentially miss that opportunity (such as offering folfox to a patient with ctDNA (+)T3N0 disease)❗️

2️⃣The DYNAMIC suggests we get same DFS rate whether we use ctDNA or conventional risks for decision‼️
✳️Then one would rightfully wonder why to use ctDNA over conventional clinicopathological criteria if we get same outcomes anyway by using MORE oxaliplation❓just to reduce 5FU❓

1️⃣ Immune checkpoint inhibitor monothetapy with dostarlimab for MMR-D is certainly practice changing❗️
✳️Although long term outcomes are needed, no need to reinvent the wheel‼️
✳️ Once a deep response achieved in MMR-D CRC it is very durable even in metastatic setting ‼️

✳️Firstly, I am categorically against putting T4 and T3 disease into same pocket (stage II is highly heterogeneous)❗️
✳️Risk of peritoneal recurrence for T4 and T3 is not same and not even close ‼️
✳️Peritoneal microscopic disease doesn’t shed CtDNA as much as liver MRD‼️

✳️Moreover, control group was a bit vague in this study, conventional risk factors are used for ad therapy which can offer you different approaches ‼️
✳️Currently there is not consensus for high risk stage II in NCCN and options include observation vs FP alone or doublet ‼️
