Helluva drug(s)! CMS spends ~$8B/yr on Keytruda,Opdivo,Rtxn,Avstn,Hcptn CMS spends ~$1.5B/yr on ALL RADIOTHERAPIES (proton included!) If CMS finagled a 1% discount/yr on these 5 drugs it would save more than RO-APM is projected to per year

Speaking at #SABR25 Dr Alison Tree 💙 raises the issue of relative underfunding of #RadOnc research 📢 <5% of cancer research funding is directed towards surgical or radiotherapy related research Yet, radiotherapy is a highly cost effective anti-cancer treatment modality

PDBrown This is fantastic! How do you reconcile elective low dose adjacent compartment vs. to entire vertebral body as per DOSIS? I have been enjoying DOSIS in my practice lately as 20/5 elective to whole VB with homogenous SIB to 40/5 for non-epidural extent cases as it is coherent and

Some great news! Robert Anton Olson ‘s SABR-COMET-3 completed accrual today!! 330 randomized with 1-3 Mets, primary endpoint OS. Biomarker studies led by Alison Allan, PhD and Rohann Correa. Readout maybe in 2027, with COMET10 likely in 2026.

When it comes to AI auto-contouring, are residents and faculty seeing it the same way? A new study by Alex Qian and Nikhil Kotha, MD shows differences between the two groups. practicalradonc.org/article/S1879-… Residents reported: • Faster CT-based anatomy learning • Major time

This might be the most badass brief report I’ve read in a long time. In NEJM A team just published what feels like a glimpse straight into the future of cellular therapeutics: successful survival and function of transplanted allogeneic, CRISPR-edited beta cells with zero

The whole medical publishing ecosystem (free content, free peer review, but $$ to publish/read) is a bizarre, exploitative business model. Even if one believes clinicians owe some degree of unpaid "academic service," it’s absurd publishers profit so massively off our free labor.

Conference travel costs add up & discretionary funds are limited. Matt Spraker has generously committed to personally funding four $500 travel awards for trainees & patients. Application process minimal. Seems like a great opportunity.

🔐 One of the key limitation for the implementation of urinary organs-at-risk in treatment planning is the large interobserver variability 🔑 Here we provide a fully available nn-Unet method for automatic segmentation of these small urinary structures! ctro.science/article/S2405-…
