Data to support why the PTV matters in primary RCC SBRT from our Aussie friends. โ€œSparing functional kidney from high-dose regions (>50% isodoses) may help reduce risk of functional loss.โ€ pubmed.ncbi.nlm.nih.gov/26873790/ MR-Linac Consortium Shankar Siva

Radiotherapy can be an impactful tool in oligometastatic disease, improving local control while micrometastases are managed with systemic therapy. Does it improve survival? Let's find out!

Great collaboration between MOMENTUM and Oligocare registries, presenting the preliminary outcomes (of 15 institutions) regarding liver SBRT using MRI or CT guided approach during #ESTRO2025 !

297 liver oligo met patients accrued from 2019-2023, with 2yr LC and OS outcome estimates reported in May of 2025! And BTW, within MOMENTUM, the accrual of this subgroup has doubled since 2023. This is the power of platform registries for emerging technologies and treatments.

๐Ÿคž2nd patient soon! ULTRAS is a Ph3 RCT (PI Ali Hosni) of 2 dose levels for 1 fx MR-guided SBRT for liver mets. A hesitation w 1 fx CT-based RT was risk of marginal miss. W better visualization & on table adaptation, I think MR-guided RT has great potential in this setting.

We asked the study team to explain NRG-CC014, the PREEMPT Study, which recently activated & is now enrolling patients with high-risk bone asymptomatic metastases. ow.ly/TngB50VSJnK Sign up for the webinar to learn more about this trial. โฌ‡๏ธ Erin Gillespie, MD MPH

๐Ÿ‘‡One step closer to Fiducial-free, Sim-free, Single fraction SABR to liver mets. That's where the MR-Linac Consortium is pushing and it will be a blessing for patients. Especially in regions where IR docs are few... and maybe even where they are plentiful๐Ÿ™‚ Ali Hosni Todd Aguilera MD PhD
