Post-prostatectomy RT in just 5 fractions? 👀
Ferrario et al and POPART team reports 100 pts treated with prostate-bed SBRT (32.5 Gy/5 fx):
• Late ≥G2 GU toxicity: 8.5%
• Only 1 late G2 GI event
• Just 3 in-field relapses
• 30-mo biochemical control: 74%
Very encouraging local control and toxicity—but urinary QoL remains important to watch.

Great presentation by @angela_jia_ and really exciting results from NRG/RTOG 0815!
#ASTRO26
@angela_jia_ and team bringing the 🔥 with incredibly important data.
Translational study of @NRGonc RTOG 0815 showing Decipher was prognostic and predictive and those with lower decipher do benefit from ADT with RT.

Very grateful for your mentorship and support over the years, Bruce. @BHaffty @HarvardRadOnc @RU_RadOnc

Reinforces the signal from NRG-GU006/BALANCE presented last year by @DrSpratticus and legacy of @felixfengmd — A step toward more personalized post-op secondary RT

New #ASTRO2026 data from @NRGOnc /RTOG 0534 SPPORT 🔬🧬 presented by Shuang (George) Zhao @UTMDAnderson. PAM50 Luminal B = both prognostic & predictive of benefit from postop ADT.
📈 5-y FFP benefit: 31% vs 10% (p-int=.01)
🎯 10-y MFS: 20% vs -3% (p-int=.05)

Posthoc analysis of RTOG 0534 independently validates NRG-GU006: PAM50 LumB predicts hormone benefit after prostatectomy (FFP +31% in lumB vs +10% non-LumB, P-int=.01; MFS +20% vs −3%, P-int=.05).
PAM50 should be SOC and has higher level evidence than Oncotype for breast cancer!

Intriguing debate on using ArteraAI biomarkers in localized #prostatecancer! @MutlaySayan @ChadTangMD battled it out. #ChrisWood26
@ChadTangMD vs Dr Mutlay Sayan from Brigham debating biomarker use in localized PCa for ADT use. Chad’s account is still hacked so we will declare Dr Sayan the winner

Inspiring, energizing, charming and a whole lot of fun.
