📌 Randomized Trial of Hypofractionated Postmastectomy Radiation Therapy in Women With Breast Reconstruction (RT CHARM, Alliance A221505) 🔗 ascopubs.org/doi/10.1200/JCO… 🔬 This randomized phase III trial enrolled 898 women undergoing postmastectomy radiotherapy (PMRT) with planned immediate or delayed breast reconstruction. Patients were randomized to: 🔹 Hypofractionated PMRT: 42.56 Gy/16 fractions 🔹 Conventional PMRT: 50 Gy/25 fractions 📊 Key findings (825 evaluable patients): 👉🏻 Reconstruction complications at 24 months: 12.3% vs 10.2%, respectively (noninferiority p=0.0001). 👉🏻Estimated LRR at 3 years: 1.5% vs 2.2%, with no statistically significant difference. 👉🏻 Acute radiation dermatitis: significantly lower with hypofractionation (G2: 20% vs 42%, p<0.0001; G3: 1% vs 3%, p=0.048). 👉🏻 Reconstruction timing: delayed reconstruction was associated with higher complication rates compared with immediate reconstruction (OR 2.96; p=0.004), regardless of fractionation. @OncoAlert #OncoAlertAF #BreastCancer #RadOnc #Hypofractionation #RTCHARM

De-escalation in breast cancer treatement is not a binary decision but a process of excellence in medicine: reduction without retreat, adaptation without surrender, precision without compromise #radonc #bcsm jmedradonc.org/de-escalating…

The 2nd Florence International Consensus on combining radiation therapy with new systemic therapies has wrapped up in beautiful Florence, Italy 🇮🇹 #FlorenceConsensus26 This year the focus went beyond breast cancer to include: 🔹 Head & neck cancer 🔹 Kidney cancer 🔹 Prostate cancer It caps a year and a half of work by a multidisciplinary team tackling one of the most practical questions in oncology: how do we integrate RT and systemic therapy the right way? 💡 When should we pause treatment? 💡 When should we combine? 💡 How do we reduce adverse events and boost effectiveness? The statements and recommendations, endorsed by @ESTRO_RT, aim to guide professionals and help us inform our patients properly. Patient advocacy was a core part of the consensus, because clear communication with patients is key to optimal treatment. 🤝 Radiation oncologists, medical oncologists, surgeons, nurses, advocates: this conversation needs all of us. Be part of the next edition and help shape how we treat our patients. 👇 @Icro_Meattini @Lucarecco @CarlottaB @RobClarkeLab @JavierCortesMD @curijoey @delmastro_lucia @ALEDIGNUS12 @Prof_Nadia_H @ClareIsacke @reshmajagsi @KaidarOrit @AnnaKirby17 @matteolambe @hoperugo @TanjaSpanic @MassimoDiMaio75 @Silke_Gillessen @DrRanaMcKay @brian_rini @alison_tree @ChadTangMD @DrYukselUrun @MicheleAquilano @GiulioFrancoli1 @DrDanielHeng @PierluigiBonomo @PBlanchardMD @piet_ost @AlbigesL @fizazi_karim @EdeAzambuja @E_de_Azambuja @BarbaraPistill2 @ESTRO_RT @AiroBreast

Should we ablate oligometastatic breast cancer? NRG-BR002 in JCO (Chmura et al.; @Docace911 @IBCradiation) gives us randomized data. 🧵 #bcsm 125 patients with ≤4 metastases and no progression on up to 12 months of first-line systemic therapy were randomized to SBRT or surgery to all sites (93% got SBRT) plus systemic therapy, vs systemic therapy alone. 79% had HR+/HER2− disease. 🚫 benefit. Median PFS was 19.5 vs 23.0 months (HR 0.92, 95% CI 0.57–1.47), and OS HR was 1.07. The trial didn't advance to phase 3. No grade 5 toxicity 👍🏻 ⚡️⚡️The interesting part: an exploratory analysis suggests patients with low or absent CTCs at baseline may get a PFS benefit from ablation. That makes biological sense, since these may be the patients with truly limited disease and less micrometastatic burden. Bottom line: no routine consolidative SBRT for oligometastatic breast cancer outside a trial. CTC-selected trials could be the next step. doi.org/10.1200/JCO-26-00201

Replying to @Erman_Akkus
Turns out IR ablations are toxic. Probably less effective. I’m not surprised but would be kicked out of tumor board for making such claims.
