Enhanced therapeutic outcomes with atezolizumab-bevacizumab and SIRT combination compared to SIRT alone in unresectable HCC: A promising approach for improved survival - 07/02/24
Highlight |
• | New innovative approach Administering AtezoBev both before and after SIRT. |
• | Administering AtezoBev both before and after SIRT is associated with improved Overall Survival and Progression-Free Survival outcomes in comparison to SIRT alone for unresectable HCC. |
• | there was no elevated incidence of side effects observed in patients treated with the combination of SIRT and AtezoBev when compared to those undergoing SIRT alone. |
Abstract |
Background |
Integrating immunotherapy with locoregional therapies marks a significant milestone in the realm of hepatocellular carcinoma (HCC) treatment . This study aimed to assess the impact of addition of Atezolizumab-Bevacizumab (AtezoBev) on the outcome patients treated with SIRT.
Methods |
We conducted a study that included all Child-Pugh A HCC treated with SIRT since 2017. We examined the effects of the addition of 3 infusions of AtezoBev before the SIRT procedure and after SIRT on patients outcome (AtezoBev-SIRT group). Time-to-event data were analyzed using Kaplan-Meier with the log-rank test.
Results |
Thirty five HCC patients treated with SIRT were included, of whom 23 % also received AtezoBev infusions. The two groups were similar in terms of liver function and HCC parameters. The median OS was not reached for patients who received AtezoBev in combination with SIRT and 14 months for patients only treated by SIRT. The median PFS was higher in the group treated by SIRT and AtezoBev vs SIRT alone (11.3 months vs 5.8 months). In the global cohort, 8 patients presented a downstaging (23 %), 4 underwent liver surgery (1 in the AtezoBev-SIRT group) and 4 liver transplantation (1 in the AtezoBev-SIRT group)
Conclusions |
The administration of AtezoBev, both before and after SIRT, is associated with enhanced OS and PFS outcomes compared to SIRT alone for unresectable HCC.
