🔬 AVATAR trial published(ER /HER2– MBC on AI CDK4/6i): In OPD, SABR delayed therapy change (mPFS 9.9 mo)
🔷 44% on same Rx at 12 mo
🔷 36% at 24 mo
Some received SABR 2–3× for new oligoprogressions—modified endpoints may better reflect its value. ascopubs.org/doi/10.1200/OA-…

Huge congrats to Dr Saad Ashraf on his @FrontOncology case report! 👏
This unique case of OPD highlights 8 courses of SABR for 17 metastases over 5 years, delaying systemic therapy changes 8x to prioritize patient QOL in a HER2 breast cancer.

Our new editorial is live! 📢
PFS & OS undervalue SABR in oligoprogression trials.
Focus on TTF, TTNT, and QoL instead—highlighting SABR as a repeatable strategic ally to systemic therapy.

@piet_ost argues the case for SABR in oligometastatic #prostatecancer - a low toxicity intervention. To better select for patients who benefit most, think biomarkers of the future (genomics), and a role for SABR in mCRPC from ARTO trial #pcsm #radonc #SABR2023
