Summary

Combination immunotherapy is currently the standard first-line systemic treatment for unresectable hepatocellular carcinoma (HCC). Approximately 30 % of patients treated with atezolizumab plus bevacizumab (Atezo-Bev) achieve complete or partial tumor response. Some patients who reach a partial response experience enough tumor regression to undergo curative therapies and subsequently attain a disease-free state. However, whether the prognosis of patients who become disease-free after curative therapy equals that of patients who achieve complete response with Atezo-Bev alone is unclear. Likewise, it remains uncertain whether patients who achieve partial response with Atezo-Bev and later undergo curative therapy fare better than those who remain in partial response without further curative treatment. Therefore, we designed this multinational, multicenter, retrospective chart-review study to address these questions.

Planned Cohorts

* Curative-therapy cohort: Patients with unresectable HCC who achieve partial response to Atezo-Bev and subsequently receive curative therapy-surgical resection, radiofrequency ablation, or definitive radiotherapy-to achieve a disease-free state.
* Control cohort: Patients with unresectable HCC who achieve complete or partial response to Atezo-Bev but do not undergo subsequent curative therapy.

Methods and End-points Data will be collected from no more than 30 hospitals worldwide, targeting roughly 400 patients in the curative-therapy cohort and 1,200 patients in the control cohort. Medical-record review will gather baseline characteristics, disease status, liver function, Atezo-Bev treatment details, curative-therapy specifics, treatment responses, and survival outcomes. The primary objective is to compare recurrence-free survival between the two cohorts. This retrospective study will close data collection on 31 March 2025.
