🌟 Exciting findings reveals that intestinal low-dose irradiation (#ILDR) enhances the effects of immune checkpoint inhibitors #ICI or chemotherapy with off target #abscopal effect and intratumoural immune activation that is dependent on Gut composition #microbiome 🦠

While widespread rediscovery and adoption of LDRT in America has always been "the goal": Never, EVER, did I think I'd live to see the day that a mainstream medicine platform like Peter Attia would open a show discussing radbio and LNT. LNT!! 10/10 from Dr. Mehta, love it.

This trial may fit nicely in your portfolio, all ROs should consider opening it. Really broad eligibility criteria and will not conflict with oligomet studies. Im excited to get it going.

#ASCO25: In LA gallbladder CA, adding CRT to neoadjuvant chemo doubled OS (21.8 vs 10.1 mo, p=0.006) & ↑ R0 resection rates (52% vs 30%) vs chemo alone in Phase III trial (N=124). First RCT evidence favoring NACRT in this tough-to-treat disease #radonc 🔗 meetings.asco.org/abstracts-pres…

#ASCO25: In pts with 5–20 brain mets, Phase 3 trial shows SRS/SRT leads to significantly better QoL vs HA-WBRT (↓ symptoms & interference, p<0.001), with no OS difference (8.3 vs 8.5 mo). SRS/SRT should be new SoC in this setting. #radonc 🔗 meetings.asco.org/abstracts-pres…

#ASCO2025 Another practice changing abstract for Gallbladder Cancer?! Phase 3 RCT in locally advanced gallbladder cancer not appropriate for R0 resection Neoadjuvant ChemoRT vs Chemo alone n = 124 (64 NACT, 60 NACRT) 🤩OS: 21.8 vs 10.1 mo (p = 0.006) ✅EFS: 10.6 vs 4.9 mo (p

PANOVA-3: gem/abraxane +/- TTF in locally advanced pancreas cancer. #ASCO25 As compared to other approved LAPC therapies, numerical benefit to TTF is non-trivial (2 month OS, improvement in pain free interval 9 to 15 months), & cost/toxicity less than many. But… 1/3

Honored to share highlights of Reena Engineer’s presentation of POLCAGB phase III trial at #ASCO2025, a game changer for locally advanced gallbladder cancer Neoadj CRT vs CT alone: 🌟 Nearly doubled mOS (21.8 vs 10.1 months) 🌟 Significantly improved R0 resection (51.6% vs 29.7%)

The most practice changing trial from #ASCO25 is now live on NEJM .If this was a drug, this would be approved today. Globally relevant and low-cost intervention that is not only delaying relapse but actually improving survival. Perfect case example of a #cancergroundshot trial.
