Even while on vacation, @aleberlin2 educates & inspires. A pioneer incorporating digital health & AI before it was in vogue, Dr. Berlin shares some techno-optimism we could all use. Plus 1 of the coolest ideas for increasing public awareness of #radiotherapy #radiationtherapy?! 🐶 🐱 @pmcancercentre @RadMedPM @WorldRTDay

🎇👏Congrats to @piet_ost @Mat_Guc @fifimcdrmh and co-authors for defining this modern framework to comprehensively evaluate meaningful endpoints after MDT, incorporating biology, clinical perspectives, and most importantly, patient input.

1/7 🧵 New in @LancetOncology: we built a Delphi consensus on primary endpoints for MDT trials in oligometastatic cancer — because the endpoints we've been using were designed for drugs, not for ablation. On behalf of the EORTC–ESTRO OligoCare consortium.

👋🚨 @AgrawalAmiya @JoannaJavor @ldawsonmd @RebeccaKSWong @RevChelvarajah Nattinee Wattakiyanon In this article we illustrated how contemporary patient-centered palliative/oligomet RT program can streamline care delivery. @RadMedPM @pmcancercentre
Advances, an ASTRO Journal@Advances_ASTRO

You'll recognize a few names on this author list! @AgrawalAmiya @CJTsaiMDPhD & team show us that palliative RT is undergoing a major evolution ⚡️—from symptom relief ➡️ a multidisciplinary, precision-driven discipline with a dedicated workflow! What’s changing? 🧠 Team-based care is central: #radonc + physicists + advanced practice RTTs + NPs + supportive care = more personalized, efficient & safer treatment decisions ⏱️ Rapid-access clinics ✔️ Referrals seen within ~24 hrs ✔️ “One-stop” visits: consult + simulation same day ✔️ Fast-track pathways deliver RT within hours for pain crises 🚀 Workflow innovation ✔️ Simulation-free RT using recent diagnostic CTs ✔️ Single-fraction treatments (8–20 Gy) ✔️ Fewer hospital visits + faster symptom relief 🎯 Better technology = better care ✔️ IMRT/VMAT + SBRT improve conformality ✔️ Reduce toxicity to normal tissues ✔️ Enable safer re-irradiation & hypofractionation 👩‍⚕️ Advanced providers expand capacity ✔️ pAPRTs: contouring, planning, workflow leadership ✔️ NPs: toxicity management, follow-up, continuity ✔️ Earlier detection of complications + improved experience 🔬 Not just care—innovation hub ✔️ Trials reducing skeletal events with prophylactic RT ✔️ Survival gains (e.g., proton CSI in leptomeningeal disease) 🚨Bottom line: Palliative RT is no longer just supportive care—it’s fast, adaptive, multidisciplinary, and increasingly impactful on outcomes and quality of life 💡 @ASTRO_org advancesradonc.org/article/S2452-…

First patterns of failure outcomes after definitive 5-fraction ablative radiation therapy for locally advanced pancreatic cancer I think both dose escalation & comprehensive elective coverage are key to achieving durable locoregional control kwnsfk27.r.eu-west-1.awstrack.me/L0/https:%2F%2…

Luke’s an incredible guy who trusted his gut to get a colonoscopy & diagnosis. His story’s a key reminder: 45 is the new 50, & if you have symptoms, any age=the right age. GI friends—are you screened? Your family? Your team? The most impactful actions are often close to home 💙
RadOncUH@RadOncUH

Powerful advocacy in action 💙 @lauren_henke sharing the stage with an incredible patient, Luke—amplifying the importance of colorectal cancer screening and trusting your gut when something feels off. Early detection saves lives. #CRC #CancerPrevention bit.ly/3Pqt4mR
