#WORLDGI2020 This is 🆒 ☢️ 32-P EUS-guided implantation in #pancreascancer #PANCSM @myESMO @WCGIC @Annals_Oncology.

Still miles to go. OS median of 16 months pointing again to the systemic nature of disease. Need to piggyback these local approaches to better systemic. #OncoAlert
#WorldGI2020 good to see more 📊on #BRCA #DDR #HRR genes 🧬 in unselected #pancreascancer patients. Wide range of 4-21%. In this study of >500 European patients, #PANCSM 4-7% ē HRR-related aberrations. Other 🧬e.g. MUTYH notes as well. 📈towards better OS but not 🔢SS. #OncoAlert
#WORLDGI2020 great times to be talking about meaningful activity in 3️⃣rd line setting in patients ē

#WorldGI2020 and this👇🏾
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‼️
🟩NTRK🧬Fusions

#WORLDGI2020 Dr. @GABOUALFA presenting now on the options & landscape of options for our patients ē #hepatocellularcancer #HCC #HPBCSM.
From

🟥And now combinations (ATEZO/BEV; LEN/PEM)
💡Sequencing is going to a challenge but a good problem🔁.
#WORLDGI2020👇🏾
“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

👇🏾We were discussing this earlier last week @ASCO_pubs.
Exploratory. 19% prolonged benefit. 💡#WorldGI2020
#WORLDGI2020 @myESMO
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
#WorldGI2020 @myESMO more discussions on 💡IDEA #clinicaltrials. What’d be of value would be integration of #ctDNA #liquidbiopsies 🩸🧬into the current algorithms of decision making. Often #ctDNA data is viewed in isolation. I see it more as an adjunct current paradigms #CRCSM.
#WorldGI2020 @myESMO
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❓
👆🏾More on the ❓raised about where the TNM classification is going for #colorectalcancer #CRCSM. From #ctDNA integration to
TNM➖I🟥Immune
#HappeningNow @myESMO #WorldGI2020
Beyond TNM & clinical variables, is molecular status or immunoscore or MRD things you are doing now?
#WorldGI2020 @myESMO #HappeningNow

🟥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
#WorldGI2020 @myESMO👇🏾THIS‼️
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
...contd. #BRCA #DNAREpair #DDR
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🙃
Can’t forget #CRCSM #POL-E hiding amidst MSS tumors. @agrothey discussing now @myESMO #WORLDGI2020 @OncoAlert
➕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.

A lot of discussion about #CEA elevations at baseline 🆚 kinetics. Of note only 77% has an elevation.

Let’s look at the ratios. See our📝 .

#WorldGI2020 👇🏾THIS is what we need to figure out.

Who are these MSI⬆️patients who don’t respond to upfront #immunotherapy. 💡

#CRCSM 💡 💭 #WorldGI2020
#WorldGI2020 @myESMO truly worth applauding the design and conduct of a surgical trial with perioperative systemic chemotherapy in patients with #ColorectalCancer ē resectable peritoneal metastases. So many moving targets. To accrue & capture all 📊👍🏽👏🏽. In practice systemic 1st.
#WorldGI2020 @myESMO @OncoAlert
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

#WorldGI2020 @myESMO @OncoAlert
👇🏾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. 🩸🧬
#WorldGI2020 @myESMO @oncoalert important to not forget about #rarecancers #RareDisease.
#cholangiocarcinoma also has the #BRAFV600E. Data on the ROAR🐯clinical trial already presented @ASCO @ASCO_pubs.

Some of the updates on 🟩HER2 ē the destiny & other agents ➕ 🟥BRAF would be 💡 to explore in @curecc. @WCGIC
#WorldGI2020 @myESMO @oncoalert
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

⚫️?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?
#WorldGI2020 @myESMO @oncoalert great summary slide looking at ❓ #immunotherapy #biomakers in #HepatocellularCarcinoma across various studies. @WCGIC
#WorldGI2020 @myESMO @oncoalert what’s the most recent consensus on #Immunotherapy & #COVID19.
While theoretical concerns, I thought that the data so far argues against any detriment. @WCGIC maybe #lcsm⬆️.

Thoughts @tmprowell @agrothey @marklewismd @weoncologists @NicoleKuderer
#WorldGI2020 @myESMO @oncoalert examples of consensus statements of #cancercare @myESMO to 📉risk of exposure to #COVID19. #PANCSM #telehealth #telemedicine 📺

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.

#WorldGI2020 @myESMO @oncoalert switching gears to #rectalcancer - one subset that merits a different systemic approach is the MSI⬆️group of rectal cancers.
Not so much the ☢️part but the chemo actually patients can progress. @sloan_kettering @FoxtrotStudy #immunotherapy
#WorldGI2020 @myESMO @oncoalert Response% in RAPIDO📖 #rectalcancer are probably one of the most discussed results. Has your institution changed practice? Our XRT oncology colleagues have been very open to it.
🔑 👇🏾takeaway “The good get a better outcome.”
?Role for #ctDNA. TNT
#WorldGI2020 @myESMO @oncoalert one 🔑 recurring theme that makes the case for TNT stronger is this👇🏾.
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💡.
