🚨 Can we delay ADT in oligometastatic HSPC… without compromising control? The phase 2 BULLSEYE trial answers this with radioligand therapy. 👥 Study population: Biochemically recurrent, PSMA+ oligometastatic HSPC - ≤5 mets, PSA DT <6 months - Not candidates for surgery/SBRT - ADT-naïve ⚡ Trial design: 🟣 ¹⁷⁷Lu-PSMA-617 (2–4 cycles) vs ⚪ Deferred ADT (active monitoring) 📊 Key results: 🔥 Progression at 30 weeks: 7% vs 93% 🔥 Median PFS: 25 vs 5 months 🔥 HR 0.07 (p<0.0001) 📉 PSA responses: - ≥50% decline: 83% vs 0% - ≥90% decline: 52% - Complete biochemical response: 24% 🛡️ Safety: Mostly grade 1–2 - Grade 3 AEs: rare (dry eyes 3%, lymphopenia 10%) - No grade 4 toxicity or treatment-related deaths 💡 Takeaway: Radioligand therapy can dramatically delay progression and postpone ADT in selected oligometastatic HSPC patients. But: Small phase 2 + crossover design → not practice-changing yet 👉 A glimpse of a future where we treat early metastatic disease without hormones? 🔖 Save this for clinic discussions 📖 Full paper in comment ⬇️ #OncoTwitter #MedTwitter #ProstateCancer #NuclearMedicine @OncoAlert @myesmo @esmo_open @asc

Prof Hugosson: Göteborg trial with 30 year outcomes! NND falls to -6-, with greatest benefit for men 50-59 at randomization. Despite no image guidance, high overdx, and suboptimal tx. Best evidence we have re: the evidence for #prostatecancer screening. Get tested! #eau26 @uroweb

Daro-PET: Ph 2 trial of Daro to enhance PSMA expression in localized PCa #GU26 @urotoday @motajmsc ♦️n=16, BL PSMA PET --> 7 d DARO --> 2nd PSMA PET ♦️n=3 (18.8%) met prim endpoint (SUVmax ≥20% increase) -- range SUVmax ⬆️ 36.5–62% ♦️n=3 had 2 prostate uptake foci, w/ heterogeneous changes in PSMA uptake after Daro

What’s new in the space of antibody-drug conjugates (ADCs) for metastatic castration-resistant prostate cancer (mCRPC)? Congratulations to Bene @bcarneiro7,  Claire, and colleagues @weldeiry for publishing this outstanding state-of-the-art review in NPJ Precision Oncology @Nature_NPJ  PMID:41238753  DOI: 10.1038/s41698-025-01131-0 ADCs represent a rapidly evolving class of biotherapeutics, combining the tumor-targeting specificity of monoclonal antibodies with the cytotoxic potency of small-molecule payloads. This comprehensive review outlines advances in cytotoxic payload and linker chemistry, and synthesizes emerging evidence on membrane antigens overexpressed in prostate cancer - including PSMA, B7-H3, STEAP1, TROP2, CD46, TF, DLL3, SLC44A4, HER2/HER3, Nectin-4, 5T4, KAAG1, ASCT2, LYPD3, Tag-72, TM4SF1, CDH3, ROR1, and PSCA. Although no ADC has yet been approved for prostate cancer due to challenges related to safety, specificity, and therapeutic window, progress in antigen selection, linker design, and next-generation payloads is accelerating development. These innovations hold significant promise to reshape the treatment paradigm for mCRPC and improve patient outcomes.

How much do urological cancers affect the working-age population worldwide? A new analysis in Annals of Surgical Oncology looked at prostate, kidney, bladder, and testicular cancers in people aged 15–64 from 1990–2021, with projections to 2050.

The CRASH-2 trial proved tranexamic acid helps in trauma. But does it help in radical cystectomy? The answer is no. Our meta-analysis (1,736 pts) published this month in the @CuaJournal explains why. Grateful to my amazing co-authors
