💙 What a feeling to publish 2 papers today in ESMO Gastrointestinal Oncology
🧬 RWE FTD/TPI + BEV in mCRC: BeTAS study
🔗 doi.org/10.1016/j.esmogo.202…
🧬 Actionable fusions in MLH1-deficient dMMR/MSI-H GI tumors
🔗 doi.org/10.1016/j.esmogo.202…
🥳 Very happy today!
@OncoAlert
🧬 PD-L1 testing in advanced GC
🔬 SP263, 22C3 & 28-8
📊 TAP showed higher reproducibility than CPS
⚠️ PD-L1 discordance across clones/scoring systems associated with worse outcomes
💡 PD-L1 assays are not necessarily interchangeable!

ARTEMIS-011 (#ESMO26 LBA9): First real progress in relapsed osteosarcoma in decades?
In heavily pretreated R/R osteosarcoma (≥2 prior lines), B7-H3 ADC risvutatug rezetecan (Ris-Rez) vs gemcitabine + docetaxel (n=122, China):
• Median PFS: 5.5 vs 1.4 months | HR 0.33, p<0.0001
• OS still immature (HR 0.51 — favorable trend)
• Toxicity trade-off: Grade ≥3 TEAEs 92.5% vs 83.3%; treatment-related SAEs 63.8% vs 28.6% (mostly hematologic)
• One G2 ILD (resolved), no treatment-related deaths
Meaningful PFS gain in a rare disease with almost no options. But higher toxicity and immature OS mean we still need global data and better toxicity management.
Would this change your practice for selected patients?

OncoAlert 4Sight Abstracts to be Presented at #ESMO26
Risvutatug Rezetecan (Ris-Rez) Versus Gemcitabine and Docetaxel (GD) in Heavily Pretreated Patients With Relapsed or Refractory (R/R) Osteosarcoma: Primary Results From the Phase 3 ARTEMIS-011 Study
🦴 Phase 3 (n=122, China): B7-H3-directed ADC risvutatug rezetecan vs gemcitabine + docetaxel in R/R osteosarcoma after ≥2 prior lines; 25% adolescents. Primary endpoint: PFS by BICR.
➡️ Median PFS 5.5 vs 1.4 mo; HR 0.33; p<0.0001
➡️ OS immature; HR 0.51
➡️ Grade ≥3 TEAEs 92.5% vs 83.3%; treatment-related SAEs 63.8% vs 28.6%
✅ Significant PFS improvement with a favorable OS trend and manageable safety, highlighting potential as a new treatment standard for R/R osteosarcoma.
