Stereotactic body radiotherapy with sintilimab and bevacizumab biosimilar in anti-PD-1 refractory hepatocellular carcinoma: the ReUNION-1 phase 2 trial.
Trial report in Nature communications, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 papers.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Immune checkpoint inhibitor (ICI) resistance in hepatocellular carcinoma (HCC) poses a major therapeutic challenge. Here we present a Phase 2 trial evaluating stereotactic body radiotherapy (SBRT) combined with sintilimab and bevacizumab biosimilar (PD-1/VEGF blockade) to overcome resistance in ICI-refractory HCC. Twenty-one patients with progressive HCC after ICI therapy receive SBRT followed by sintilimab 200 mg and bevacizumab biosimilar 15 mg/kg every 3 weeks. The primary outcome, objective response rate in non-irradiated lesions is 33.3%, with a disease control rate of 66.7%. Median progression-free survival is 6.2 months, and estimated median overall survival is 24.4 months. SBRT achieves 100% local control, with 33.3% experiencing grade 3 or higher adverse events. Proteomic profiling reveals that responders exhibit lower baseline IFN-γ and elevated IL-6, while post-SBRT increases in IFN-γ, IL-2, and IL-6 correlate with improved outcomes. These results indicate that combination of SBRT in ICI-refractory HCC is effective, well-tolerated, and may be guided by cytokine assessment.
