SBRT superior to thermal ablation (and non invasive without tumor size limitations). This is without even accounting for use of advanced technology with adaptive RT or surface monitoring and gating, etc. Fortunate to have many excellent urologists @LPonsky who have helped…

This is the beginning of the end for #prostatectomy in localised #prostatecancer. In future, prostatectomy should be reserved for patients with severe LUTS and large prostates. Patients deserve an honest discussion about PACE-A & Protect Trial results, & surgical learning curves

In PACE-B (@nickva1, #ASTRO23), only 3.5% of patients recurred after 5y. In our @Sunnybrook #SBRT series only 5% of fav int risk patients recurred after 10y (Kennedy T, #ESTRO24) Maybe you could clarify what you meant by “common occurrence”?

What if your prostate cancer returns after radiation therapy (a common occurrence)? There is so much more than simple observation or hormone tx! Dr. Todd Morgan @wandering_gu presented new #AUA24 Guidelines supporting ablation, surgery, and repeat radiation. @FocalSociety

In the #PSMA #PETimaging arm of the randomized PSMA-SRT trial @UCLA and @UCSF, M1 disease was detected in ~10% and there was 18% more treatment escalation than in the control arm. Will this lead to improved PSA outcomes? Analysis is planned for 2025. sciencedirect.com/science/articl…

Radiation to asymptomatic bone metastases reduces SREs (incl fractures, cord compression). Primary results of our phase 2 RCT ⚖️ were published (below). If you don’t have access to the full manuscript 📑, please DM me. 🙏 #radonc #medonc

#SBRT actually numerically better - will need more time to see whether it will be statistically superior. Between PACE-A and B, SBRT is the new SOC option for intermediate risk prostate ca (better sexual and incontinence vs RP; same efficacy, more convenient than CRT)

RADICALS-RT trial was just updated at #ESMO23 by Dr. Noel Clarke. The trial compared adjuvant versus salvage RT in localized prostate cancer after radical prostatectomy. Similar benefit for MFS or OS.
