Figure 3. Kaplan-Meier curve of overall survival (OS) by objective response (OR).
Patients who achieved OR after transarterial radioembolization (TARE) had a significantly longer median OS of 17 months compared with patients that did not who survived a median of 10 months (p=0.03). Response was landmarked at 2 months after TARE, since response status was not known until the first follow-up PET/CT. The analysis includes patients with imaging response assessment who were followed for at least 2 months (n=58).
