Interpreting liver mets on MRI can be challenging, in part b/c imaging features (hypo vs hypervascularity) vary by primary tumor site. I adapted this slide from Dr. Jim Apisarnthanarax presentation at ASTRO. Important for diagnosing & if treating w MR-guided RT.

Enjoyed co-leading liver SBRT workshop & nice to see how ROs practice globally. In US, SBRT constrained to 5 fx (billing, pt convenience), but in Germany 7, 12 fx often used. Table shows how more fx maintains ablative dosing to tumor (BED10) but spares normal tissues (EQD23).

The optimal management of oligometastatic HNSCC is a debated and important question. How can we improve *overall survival* in this more favorable population? EA3211 is a phase III randomized trial studying this exact issue. Enrollment is even more streamlined with the most

I’m not privy to his clinical details so can’t fully comment but feel that the data supports RT in de novo mHSPC (regardless of volume of ds) PEACE-1 showed RT improved time to mCRPC and GU adverse events (and OS if not getting ARPI)

It’s with deep sadness that we share the unexpected passing of our daughter and sister, Emman. She brought so much joy, laughter, and love into our lives and into the lives of everyone who knew her. Emman had a way of making people feel seen and heard, and she wasn’t afraid to

The final results from the phase III TRILYNX study recently dropped, comparing X+CRT with CRT in HPV-negative HNCC, and not only was it negative but it suggested worse toxicity AND disease-control outcomes with xevinapant. ascopubs.org/doi/10.1200/JC…

Should we think about 3 tier SABR response following kidney SABR? Shankar Siva Chad Tang, MD Jeff Ryckman Nicholas Zaorsky, MD MS I am just liking this initial version which I just put together for a recent talk. May be adding “reassuring” for non-progressive

#RT utilization rate for #CTCL only 29% over all treatment lines. Unexpectedly lowest in highly accessible areas; no distance-decay association. Geographic disparities in diagnosis & RT-utilization rates may relate to dermatologist & linac availability ➡️ redjournal.org/article/S0360-…

Great to see the updated BCLC guidelines include RT! RT now incorporated into most major guidelines for HCC (BCLC, AASLD, EASL, NCCN, others) & should be a standard of care option. Full link here: sciencedirect.com/science/articl… OncoAlert
