Adjuvant RT may finally be back in bladder cancer. The phase III BART trial shows that modern pelvic IMRT after cystectomy significantly improves locoregional control in high-risk MIBC. 🚨 🇮🇳 Multicenter randomized trial 153 patients 90% received perioperative chemotherapy 🩻 Adjuvant RT vs Observation after radical cystectomy 📌 2-year LRFS 87.1% vs 76.0% HR 0.43 (P=.04) 📌 2-year DFS 71.6% vs 58.7% 📌 2-year OS 70.4% vs 57.4% Most striking finding: ❌ No isolated pelvic recurrence after adjuvant RT. Despite historical concerns, toxicity remained low with modern IG-IMRT: ⚠️ Grade ≥3 acute toxicity: <5% ⚠️ No major increase in severe late toxicity This is important because pelvic failures after cystectomy are often devastating and rarely salvageable. The study strongly reopens the discussion around integrating pelvic RT into multimodality care for high-risk bladder cancer, especially in the modern immunotherapy era. Could adjuvant RT + IO become the next frontier in MIBC? 📖 Full paper in comment ⬇️ #OncoTwitter #MedTwitter #BladderCancer #RadOnc @ASCO @myesmo @esmo_o @OncoAlert

DEAR COLLEAGUES A reminder that #APCCC26 🇨🇭is coming in 2026 This is a Conference is OPEN TO EVERYONE, not just the Panel members and EARLY REGISTRATION is up until February 28, 2026 Awarm invite to the Advanced Prostate Cancer Consensus Conference #APCCC26 in Lugano🇨🇭 REGISTER HERE: apccc.org/apccc-2026/ Event Details: 📍 Palazzo Congressi, Lugano, Switzerland 🎟️ Register here 🎓 Credits requests: SGU – SSU, SSMO, SRO, SGMN In an era of rapid innovation and expanding treatment options for advanced #ProstateCancer , APCCC provides a vital forum for clinicians and researchers to address complex clinical questions where high-level evidence is limited. Over two days, the world’s leading experts will engage in high-level presentations, debates, and discussions to clarify and conceptualize the current landscape of care, with a focus on areas of controversy or uncertainty. The insights and consensus developed during the meeting are later published in European Urology, helping shape global standards. Creating new opportunities for younger investigators & the next generation of leaders in advanced prostate cancer! @Silke_Gillessen & @AOmlin @OncoAlert 🚨 @fabioturco92 @Prof_IanD #PROSCA25 @drjefstathiou @Prof_Nick_James @ChrisSweens1 @BertrandTOMBAL @ZilliThomas @neerajaiims @bjartell @PBlanchardMD @BourlonMaite @Albert0Briganti @cdanicas @Ecastromarcos @mdesantis234 @nachoduranm @drlouiseemmett @stefanofanti4 @fontev1 @Nicola_Fossati @marty_gleave @ProfKHerrmann @DrMHofman @BarbaraJereczek @ravikanesvaran @FacsRaja @LoebStacy @quimmateo @DrRanaMcKay @amerseburger @CaPsurvivorship @declangmurphy @DrPaulNguyen @WilliamOhMD @piet_ost @DrSpratticus @cnsternberg @DrYukselUrun @DrChoueiri @tompowles1 @brian_rini @nataliagandur

A great Pleasure to Present our paper on Management of patients with Advanced #ProstateCancer : A Report from #APCCC24 LINK TO ARTICLE👇👇👇👇👇👇👇👇 sciencedirect.com/science/ar… The 2024 Advanced Prostate Cancer Consensus Conference (APCCC) highlights significant advances in prostate cancer management while underscoring areas where high-quality evidence is still lacking. The conference gathered expert opinions on controversial clinical issues, particularly in advanced prostate cancer, offering guidance in cases where guidelines are unclear or conflicting. The report emphasizes personalized treatment approaches, considering patient-specific factors and evolving clinical data, and stresses the importance of ongoing clinical trials to fill knowledge gaps. It provides a practical framework for physicians and patients to engage in shared decision-making, especially in complex cases of high-risk localized and locally advanced prostate cancer.

We learned a lot about muscle-invasive bladder cancer this past week. Together, these studies suggest that a strategy worth exploring is to further de-intensify surgical lymph node management to reduce surgery-related mortality, while using adjuvant radiation to treat nodes in the ~30% of patients found to have pathologic T3-4 disease. 1. SWOG 1011 (Lerner SP et al NEJM 2024) shows that a more extensive pelvic LN dissection causes more harm than good, even in clinical T3-4 disease. (>10% of patients in extended lymphadenectomy group died within 6 months of randomization.) 2. SWOG 1011 suggest that if we could better manage pelvic LNs in pts with pathologic T3-T4 disease, we might improve cancer control. (HR~2, but we can’t know if a patient is pathologic T3-T4 till after radical cystectomy due to clinical-pathologic discordance problem.) 3. Marcq et al (JCO 2024) from McGill U. suggests that RT to pelvic LN is effective (in intact setting). (Multiple RCTs from Zaghloul M et al suggests RT effective in post-op setting too (most recent in IJROBP 2024)). 4. BART Trial (Murthy V et al ASTRO 2024) from Tata Memorial Hospital suggests that adjuvant radiation after radical cystectomy does not appear to meaningfully increase late toxicity. (Small bowel obstruction rates, our greatest worry, were similar with and without adjuvant RT.) @slernerbcmedu1 @siadaneshmand @VedangMurthy @docpriyamvada @BrianBaumannMD @TataMemorial @gautiermarcq @WesKassouf @SWOG @PaulSargos @fontev1 @NEJM @IJROBP
