Online now: our report in EJC compiles toxicity data from 213 pts across 3 multi-site SBRT + immune checkpoint inhibitor trials at UChicago to characterize the toxicity profile of combined modality treatment: https://t.co/n6o113ybzu
We found rates of toxicity were similar to those seen in major trials of ICI alone, suggesting that SBRT adds minimal toxicity (consistent with low rates of SBRT tox in SABR-5 and recently OligoCare). Critically, standard SBRT constraints were used with priority on OAR sparing.
Considering negative trials of radiation and immunotherapy in light of available preclinical and translational data. Our review of this rapidly evolving field: https://t.co/9Ym4qazNkX
Could we hold off on checkpoint inhibitors in patients with low-volume metastatic disease and treat with local therapy instead? Our editorial exploring this idea: https://t.co/nR8582LmMZ (thanks to @rweichselbaum@MuzamilArshad18@RohanKatipally@SeanPitroda)

@ajuloorimd@UCCancerCenter Thanks for the shoutout! One of the great things about training @UChicagoRadonc is working with cool data like this. Looking at our SBRT/ICI trial data we realized we had a kind of natural experiment going on (ICI w/ or w/o liver met SBRT).
@ajuloorimd@UCCancerCenter@UChicagoRadonc Reassuringly we found that overall combined modality treatment is, as @Docace911 always says, SAFE. Given that our liver constraints were easily met, there is likely room to dose-escalate for these tougher-to-control liver mets.
