Exciting to see these results out! Lots to build on - congratulations @ superb MSK pancreas team (no biases!) and complex insightful analyses led by @CentralParkWMD @MSKCancerCenter and as #ASCO23 winds down…. back to the real work of implementing all the learnings to practice!

Great opportunity to hear about the latest in pancreas cancer research and treatment.

[Fionnuala Crowley @FionnualaCrowle]

Thanks to @medpagetoday for highlighting our @JCO_ASCO article. Need to write more soon on how primary palliative care looks/works in a busy oncology clinic. Shout out to my amazing clinic team (including Irena quoted) who are the reason we can provide this comprehensive care.

[Wungki Park, MD MS @CentralParkWMD]

This will be absolutely a fun 🤩 event.
Looking forward to interactive and insightful discussions 🎙️with the KOLs 👑 who shape this field in K/RAS 🧬 field!

Happy 😆 to join Toni @GIcancerDoc Eileen @EileenMOReilly and John Strickler 👏

KRAS-mutant GI malignancies are one of the fastest-moving areas in oncology right now.

Let’s dig into the biology, the evolving treatment landscape, and real-world case discussions with colleagues at our 2026 ISGIO Spotlight CE Session: Precision Pathways in RAS-Mutant GI Malignancies.

Bring your toughest questions (don’t be kind. @GIcancerDoc will take it 🤣) and we will talk through it together. I hope to see you there October 2-3! Register with code PARK for free registration: https://t.co/V3c1IjJ7xl

Very grateful for this @JamesClearyMD means a lot coming from you. 🙏

We think the most interesting question now is how to turn this biology into the next generation of strategies for HRD pancreatic cancer. There is so much still to understand across DNA repair, neoantigens and immune engagement. 🧬

Would love to compare notes and think together about where this can go next.

You have super exciting work so would love to connect. Maybe at DFCI BRCA symposium around 11/11 if you are around? 😉

A melanoma (mRNA cancer) vaccine was hailed as a breakthrough. Which cancers are next?

And if you're interesting in joining us in our adventure into toxicity, germline genetics, and precision safety, consider applying to this open postdoctoral position.

[Marc Hilmi @MarcHilmi]

I’m incredibly grateful for your mentorship, trust, and support throughout this project. It has been such a privilege to build this story together with you and the whole team. 🙏🌟

[Marc Hilmi @MarcHilmi]

Years of work distilled into one lesson. Finding expanded T cells was not enough. We had to trace the same clonotypes from blood into tumor, localize them spatially and ask what they recognized. Deeply grateful for the mentorship, trust and extraordinary team that made this possible!
