Excellent study @migrantmedic @EbnerMD @tmalouff @wgbreen @TheColonelGray @MayoClinic & @MayoRadOnc colleagues 26 patients 10-15% Amyloidosis is local (98% AL type) ~50% recurrence trach-bronch Dz w/surgery alone If bulky residual consider RT boost

H&N Amyloidosis majority tracheal-bronchial 20Gy/10 most common regimen-min toxicity 66% symptom improve 93% fav response (1/2stable 1/2response) Consider RT for high risk or recurrent Dz https://t.co/IqixIPtd5m

Congrats Dr. Souvik Sankar Das & colleagues Won’t change my practice, I favor SRS even for many brain mets esp w/ much larger Aizer trial results

Congrats @Rrkotecha @MiamiCancerInst colleagues In my practice radiofrequency ablation/vertebral augmentation primarily for at risk lesions (higher SINS score)

Does the addition of radiofrequency ablation/vertebral augmentation to radiotherapy improve pain outcomes for painful spine mets? NO according to this Phase IIR https://t.co/kUrz5IaeFZ

Greatly enjoyed the focus on benign diseases at ASTRO. Should there be a change in name to reflect this growing practice?

Is there an alternative to HA-WBRT+memantine to decrease risk of new brain mets? Yes, in this randomized trial Tumor Treating Fields prolongs time to intracranial progression w/o affecting QoL or cognitive function https://t.co/K3OKPJHXCm

🚨 PCI in SCLC: Rethinking the standard 🧠 👩⚕️ NRG-CC003 (Phase II/III) • HA-PCI = hippocampal-avoidance prophylactic cranial irradiation • ↓ neurocognitive decline 🧩 • Maintained intracranial control 🎯 • No OS difference ⚖️ 📊 Other HA-PCI trials • PREMER 🇪🇸 → less
