Advanced coming in subsets #PrecisionMedicine. “Target-rich” 🎯

More than just the ORR% in this setting, is how brisk, robust, & durable these tend to be ➕ECOG📈.
As noted @NEJM📝 & in our experience as well, have had stage-IV pts get secondary ‘curative’ resections‼️

🟥And now combinations (ATEZO/BEV; LEN/PEM)
💡Sequencing is going to a challenge but a good problem🔁.

“Genomic fragmentation of metastatic #colorectalcancer”
Although I see fusions, I don’t see mention of #NTRK separately.
💡Even though rare, imp. to know that especially the MSI⬆️are enriched in NTRK🧬. Dramatic durable responses. Who to test? #CRCSM #oncoalert

🦗👇🏾is the closest to one of the utilities of using 🩸🧬in clinic for metastatic #colorectalcancer patients.

🟢PD1⛔️➡️RAM/TAX📈
🔴RAM/TAX➡️PD1⛔️
👇🏾We were discussing this earlier last week @ASCO_pubs.
Exploratory. 19% prolonged benefit. 💡#WorldGI2020

If the most important strides or 🔑 #clinicaltrials could be summed up in ☝🏽 slide, it is this👇🏾:
#Immunotherapy➕💊some TKI or VEGF⛔️
1️⃣Atezo➕BEV
2️⃣Len➕Pem
3️⃣Rego➕PD1/PDL1⛔️
4️⃣Cabo➕Nivo
What other combinations are you excited about❓#CRCSM #HPBCSM


I know we have had some discussions before @ASCO. How do you see the current 👇🏾#TNM classification changing ē novel markers #ctDNA #immunoscore ?stroma.
Esp. for ctDNA➕, do you see those pts as early stage+ like N1c(deposit) or are these truly stage4️⃣❓

TNM➖I🟥Immune
#HappeningNow @myESMO #WorldGI2020
Beyond TNM & clinical variables, is molecular status or immunoscore or MRD things you are doing now?

Learning more beyond just
🟥MSI⬆️
#BRCA-ness
#DNARepair in #colorectalcancer
More data on #TMB from the TRIBE study. Here they used @carisls & cutoffs of 7️⃣ for the intermediate & 1️⃣6️⃣for high. Seems like more proximal tumors ē higher TML#CRCSM




The list of actionable aberrations in #colorectalcancer keeps increasing.
More importantly see:
#BRCA #DNAREPAIR 1️⃣4️⃣%🧬✅
We don’t talk much about that in #CRCSM. 💡need #clinicaltrials. Again need for NGS upfront ē 📈young-onset CRC. @OncoAlert




We had reported on this 2 yrs ago & also compiled all data. If you look at even germline studies, if UNSELECTED #CRCSM ~2% deleterious #BRCA. If we did a PANEL, we will find more. Like the 👆🏾study ē 1️⃣4️⃣%‼️#WorldGI2020 Hardtime finding a sponsor🙃

➕worth reiterating another case of MSI⬆️who was classified as pMMR/MSS picked up by NGS‼️
It may sound small numbers, #Immunotherapy’s impact not small for these pts.

Switching gears to

#CRCSM #BRAFV600E
A lot of discussion about #CEA elevations at baseline 🆚 kinetics. Of note only 77% has an elevation.
I wanted to share/propose some💡. @agrothey @skopetz
Let’s look at the ratios. See our📝 .

#CRCSM 💡 💭 #WorldGI2020


I’ve always been very impressed ē the OVERALL SURVIVAL reported for patients ē #colorectalcancer on some of these trials. 👇🏾~4️⃣3️⃣ MONTHS for patients ē peritoneal metastases

It’s more the CRS that’s worth➡️📈.

👇🏾this I have a hard time believing.
I don’t think just on chemo+VEGF⛔️one can “CONVERT” #KRAS➕patients to wild-type. Acquisition post EGFR⛔️I get & makes sense. I have not seen this. On therapy shedding📉. It is not detectable ❌= conversion.

🧬#HER2🟩
Some of the challenges that are being discussed now can potentially in my opinion be overcome by using #ctDNA #liquidbiopsies in parallel at baseline & at progression. @YJanjigianMD showed some data & work by @DocCatenacci earlier. 🩸🧬

#cholangiocarcinoma also has the #BRAFV600E. Data on the ROAR🐯clinical trial already presented @ASCO @ASCO_pubs.
Didn’t need the same 🚂 ⛔️EGFR⛔️BRAF⛔️MEK
Dual inhibition sufficient.

“TARGET-RICH” 🎯
What else would you add?💭
Some of the updates on 🟩HER2 ē the destiny & other agents ➕ 🟥BRAF would be 💡 to explore in @curecc. @WCGIC

I think this👇🏾slide is probably the 1st of many to come where expert discussants are commenting on the utility & integration into practice for #ctDNA #LiquidBiopsies.
🟢at diagnosis for #CRCSM
🟢at the time of EGFR⛔️re-challenge 🦗 #clinicaltrials

🟢HER2
🔵MMR/MSI
🟣PD-L1
⚪️EBV
⚫️?TMB
🔜BRCA/DDR #clinicaltrials
Of note ⚪️EBV more in gastric than GEJ/Esophageal. Mutually exclusive to 🔵dMMR/MSI⬆️. 2-4% in most series. 💭 @GillSharlene add #TMB?


While theoretical concerns, I thought that the data so far argues against any detriment. @WCGIC maybe #lcsm⬆️.
Thoughts @tmprowell @agrothey @marklewismd @weoncologists @NicoleKuderer

With the decrease in surgeries, there was more leaning to do neoadjuvant approaches & shorter courses of XRT.

Discussion of #MinimalResidualDisease #MRD - 📊 in OLIGO-metastatic #CRCSM.

Not so much the ☢️part but the chemo actually patients can progress. @sloan_kettering @FoxtrotStudy #immunotherapy


🔑 👇🏾takeaway “The good get a better outcome.”
?Role for #ctDNA. TNT

Post-operative compliance & rates of completion of chemotherapy are a lot lower. And that’s not just for rectal cancer, similar themes in #PANCSM arguing in favor of TNT💡.
