Extremely excited to share our latest article published @TheLancetOncol a few hours ago: https://t.co/du9hQOzHv7.

The WOLVERINE individual patient meta-analysis was an international collaboration and part of X-MET collaboration. Goal was to evaluate MDT in oligomet prostate ca.

How long should ADT really be with definitive RT

🚨 NEW JAMA ONCOLOGY META-ANALYSIS
10,266 pts • 13 RCTs • MARCAP IPD

🎯 Key Finding :

📉 Benefit rises rapidly up to ~12 months
🛑 After 12 months → benefit plateaus
⚠️ But OCM (non–prostate cancer deaths) steadily increases with longer ADT
➡️ So the “longer is better” rule is NOT universally true.

🧬 Optimal ADT Duration (by 10-year DM + NNT curves):
🟦 1 intermediate-risk factor: 0 months
🟩 ≥2 intermediate-risk factors: 6 months
🟧 NCCN high-risk: 12 months
🔴 Very high-risk: No clear plateau - prolonged ADT still beneficial

🧠 Clinical Interpretation:
•IR → Short-term ADT is enough
•High-risk → 12 months is the sweet spot
•Very high-risk → Consider long-term ADT

Always balance:
✅ PCSM ↓
❌ OCM ↑ with duration
🎯 Life expectancy + comorbidities + patient preference

🌍☢️ Today is #WorldAwarenessRadiotherapyDay
Radiotherapy saves lives: it treats over 50% of cancer patients with increasingly precise and safe techniques.
Let’s recognize the work of those who make it possible and keep driving access and innovation.

Is there a potential role for prostate SBRT < 5 fractions?

Great to share our @EurUrolOncol TOFFEE meta-analysis comparing 2⃣- and 5⃣-fraction prostate SBRT for intermediate-risk prostate cancer
@DrAndrewLoblaw @Sunnybrook @UofTDRO

📃individual patient data meta-analysis of 4 prospective trials
🧍‍♂️199 patients
⏲️9.4 years median follow-up
↔️similar biochemical failure (5y 3.6% for 2⃣-fraction vs. 6.0% for 5⃣-fraction)
↔️similar urinary or bowel patient-reported QoL

A 33 min overview of GI rad onc!

I made this video for an oral boards review course, sharing here.

It’s just 5 slides (below) &amp; me talking the whole time, so you can just listen.

Hope it’s helpful! Link next post, and short 🧵.

🚨Pooled CAO/ARO/AIO-12 and OPRA Rectal trials🚨

Study suggests that selective WW compared with planned surgery offers:
✅ Comparable OS and DFS!!

🔥 Supports WW as a highly appropriate, and potentially preferable, option for patients with cCR after TNT‼️

Cualquiera de esos chavales tiene más dignidad, lealtad y honor que todo el gobierno de Sanchez.

Ellos sí saben honrar a la Benemérita y a sus héroes caídos, en acto de servicio, contra el narcoterrorismo.
