Nina Sanford: Unresectable HCC treated with IO+SBRT
Nina Sanford posted on X about recent paper by Chi Leung Chiang et al., titled “Complete Response to Locoregional Therapy Plus Immunotherapy for Hepatocellular Carcinoma” published on JAMA Oncology.
Authors: Chi Leung Chiang, Kenneth Sik Kwan Chan, Keith Wan Hang Chiu, Francis Ann Shing Lee, Wenqi Chen, Natalie Sean Man Wong, Ryan Lok Man Ho, Venus Wan Yan Lee, Kwan Man, Feng Ming Kong, Albert Chi Yan Chan.
“Unresectable HCC (median tumor diameter 10cm, 60% MVI) treated with IO+SBRT (N=63):
-46% achieved complete response, much higher than prior trials of IO alone: atezo/bev (CR 5.5% IMBRAVE150) and STRIDE (3.3% CR)
-CR associated with better OS (3yr 76% vs. 28%)!
Other points:
-Interestingly the median dose was 35 Gy in 5 fractions: HCC is radiosensitive & may not need ablative dosing, particularly when combined w IO.
-TACE allowed (78% received pre-SBRT)
-Upcoming RCT NRG GI012 will assess atezo/bev +/- SBRT.”
