Appreciate the⚠️caution voiced by #PCWG4 @AarmstrongDuke et al.@JCO_ASCO #PSMA imaging in #ProstateCancer is not🚫ready for prime time to determine treatment failure (distinct from imaging PD) in clinical practice PSMA may harm pts if it leads to stopping a tx too quickly

Great way to cap off #colorectalcancer awareness month hosting our @CSCancerCenter #CRC research social w/Dr. Alessio Pigazzi @EdwinPosadasMD for a productive exchange of ideas, networking & future collabs w/PhDs & MDs in #CRC research @AGangiMD @fdossa @SGrivennikov @SekiEki

The @thenci past meets the present @asco #GU26 Dr. Melissa Abel @melissaabel20 discusses emerging #PSMA tumor volume data with Dr. Harpreet Singh @harpreet_md The emerging data is from a follow-up trial based on a trial Dr. Singh worked on during her time @theNCI

Breaking news from @ASCO #GU26 👉Adding belzutifan to adjuvant pembrolizumab significantly improves disease free survival (HR: 0.72)👉Congrats @drchoueiri & team for changing SOC again in pts with #kidneycancer @kidneycan @OncoAlert @urotoday

As we get ready for the update on the overall survival in #BRCAAway trial @asco #GU26 It is worth noting the small number of patients that’s crossed over. In that context this data has its limits in comparing combination vs sequence in #ProstateCancer
Here is the crossover data from #BRCAAway trial. Small numbers in study accentuated by limited crossover. This highlights in this setting this is really a question of #PFS2 not just #PFS #ProstateCancer @asco #GU24

Great points from Dr. Koontz. Biology should drive decision making #GU26

Replying to @AmarUKishan
@AmarUKishan POSEIDON meta-analysis of 6 PhIII RCTs on hormonal therapy (HT) after post-op RT (PORT) in localized #Prostatecancer ➡️ no OS benefit w/HT to PORT & no significant interaction b/t duration of HT & this effect (p-interaction 0.25) for PSA<0.5 #GU26 @OncoAlert

#BRCAaway OS data presented by Dr. Maha Hussein #GU26 @asco Launched prior to large phase 3s in #ProstateCancer Cancer Provocative data but as Dr Hussein acknowledges small numbers in cross over (8 patients) limits ability to truly understand sequencing vs combo

Dr Evan Yu takes stage @asco #GU26 to discuss #Peace3 & #BRCAaway Too often superlatives are thrown around on this app… But do yourself a favor. Watch this whole discussion. One of the more thoughtful takes on modern clinical trial dilemmas in #ProstateCancer Thank you Dr Yu

It’s always a beautiful day when you can go to clinic and observe a successful #bicalutamide withdrawal maneuver 📉 Yes… even in 2025 🙂 Sometimes less is more in #ProstateCancer (#nmCRPC) Flashback to Dr. Evan Yu & colleagues… tinyurl.com/257dptx2

What did I learn at #ASCO2025 ? 1. Increasing intensity of treatment improves PFS& toxicity- still need OS data for shared decision making 2. Powerful new treatments for #ProstateCancer are coming. get patients on trial 3. Get biomarkers on your #ProstateCancer Thanks everyone!

As new #mCSPC #PFS data is unveiled w/#PARP & Lu-PSMA it is worth nothing all previous mCSPC trials showed OS despite large functional cross overs Did we lower standard to PFS when both agents are approved for mCRPC? 🤔 #ProstateCancer #ASCO25 nature.com/articles/s41585-0…

Great discussion from Angela Jia: contextualizing these 2 abstracts was key. Love the point of PSMA-PET and STAMPEDE when interpreting this data and contemporary RT approaches for localized PCA #ASCO25
