🚨The first American guidelines for low-dose radiotherapy in osteoarthritis were just published.
That’s not a small thing.
For decades, European centers have been treating OA with low-dose RT. American patients largely couldn’t access it. No formal guidance. No insurer framework. No roadmap for referring providers.
That changes today.
The American Radium Society Appropriate Use Criteria, published in the American Journal of Clinical Oncology, define exactly when and how to use LDRT for OA. Radiation oncologists, rheumatologists, physiatrists, and orthopedic surgeons built this together.
For insurers, this is the clinical framework they’ve been waiting for.
Honored to be a co-author alongside the global experts who made this possible.
PSMAddition: Ph 3 trial of ¹⁷⁷Lu-PSMA-617 + ADT/ARPI in PSMA+ mHSPC (n=1,144)
🚨 PSA Endpoints 🚨
Primary endpoint:
🔹rPFS: HR 0.72 (95% CI 0.58-0.90; p=0.002)
PSA endpoints:
🔹PSA90 at any time: 89.5% vs 85.6%
🔹PSA <0.2 ng/mL at 48 wks: 87.4% vs 74.9%
🔹PSA <0.02 ng/mL at 48 wks: 65.3% vs 46.7%
🔹Time to PSA progression: HR 0.42 (95% CI 0.30-0.59)
Adding ¹⁷⁷Lu-PSMA-617 increased the frequency and depth of PSA responses and reduced the risk of PSA progression by 58%

This is very important for patients, providers, and regulators to understand. ICECAP showed MFS by conventional imaging is a surrogate endpoint (strong correlation to OS treatment effects and high surrogate threshold effect (STE)).
However, multiple groups have shown that event-free survival (EFS) very closely mirrors PSMA PET/CT MFS. Thus, use of EFS or PET defined MFS have very poor correlation to OS, very low STE, making it nearly impossible for any trial to have a HR low enough for it to serve as a surrogate endpoint for OS.
I hope @DrMakaryFDA and FDA appreciate this. Inhibiting AR will nearly ALWAYS lower PSA. Thus, testoerone suppressed for prolonged period you will near always improve BCR --> EFS --> PSMA PET defined MFS. None of that means you improved outcomes or survival.

1/7 🧵 New in @LancetOncology: we built a Delphi consensus on primary endpoints for MDT trials in oligometastatic cancer — because the endpoints we've been using were designed for drugs, not for ablation.

New research from @jsunny99@thayerschool reveals FLASH radiotherapy's normal tissue sparing effect requires sequential deliveries to be within ~10s—matching tissue reoxygenation time. Split-dose study provides key evidence linking oxygen dynamics to the FLASH effect. Read about it in the #RedJournal: https://t.co/D0nYc9Pdti
The phase 3 PSMAddition trial has met its primary end point, showing that lutetium (177Lu) vipivotide tetraxetan plus SOC significantly improved rPFS vs SOC alone in patients with PSMA-positive mHSPC. #pcsm

Check out the latest @ASCO guidelines on functional NETs. While management of well-differentiated NETs is often nuanced, three critical factors should be assessed at the initial visit to guide an effective treatment plan:
1.Tumor Grade
2.Disease Stage
3.Functional Status

Carboplatin + involved node radiotherapy (INRT) is now a treatment option for seminoma stage IIA/B in the latest version of the #NCCN Guidelines . Thank you to all patients who took part in #SAKK0110 & #SAKK0118 and to all collaborators. @sakk_ch
Potential Impact of LDRT: The addition of LDRT appears to have mitigated some of the degenerative changes typically seen in osteoarthritis progression, suggesting a potential protective or slowing effect on joint deterioration.

Decipher GC for predicting treatment prog in AS pts, adjusted for mpMRI findings (n=338; f/u: 26 mo)
🔹GC score ≥0.45 assoc w/ ⬆️rate of tx prog in both pts with PI-RADS 1-3 & 4-5 lesions (HR: 1.6, p=0.05)
🔹mpMRI PI-RADS 4-5 lesions not assoc w/ rate of tx prog in pts with GC score ≥0.45
📍Findings further support NCCN recs to consider incorporation of Decipher for risk strat of clinically localized PCa pts
