The PROP (Pall RT & Oligomet Progeam) @pmcancercentre @UHN would not be successful without our #APRT (previously CSRT). They play a vital role in patient care and clinical trials. Would love to see an expansion of such endeavor. @YatTsang @DKirschMDPhD @ldawsonmd

Is it time to rethink the role of the RTT in U.S. #RadOnc? What is an Advanced Practice Radiation Therapist (APRT)? Globally, APRTs are stepping into expanded roles—but in the U.S., that concept doesn’t yet exist. Should it? Let’s break it down. 🧵 #RadiationTherapy #APRT 1/7

En route to @NRGonc and will speak with colleagues about updates of @CDNCancerTrials @NCICancerTrials #CURB2 trial. This sign at the airport seems fitting! @KHigginsMD @JeffBradleyMD @UofTDRO @RadMedPM

🚨🚨🚨 We are activating this single-arm phase 2 trial of hypofractionated RT to oligoprogressive metastatic #melanoma, up to 10 lesions + extensive specimen collection for correlatives. There's an unmet need in this area - hope results of the trial will benefit more patients.

Interesting paper, although I wouldn't have included CURB since it's not OMD. Also would include LU002. Efficacy and Safety of Metastatic Directed Treatment of Oligometastatic Disease: Results of a Meta-analysis - Advances in Radiation Oncology advancesradonc.org/article/S2452-…

Hilarious. 😂 Should add that if p>0.05 some might change endpoint and re-analyze! This is just unthinkable when in grad school the mere mention of p value will give us negative points in exams!
