Organ-specific response with first-line atezolizumab-bevacizumab versus lenvatinib for patients with advanced hepatocellular carcinoma.
Article in Hepatology international, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
backgroundImmune checkpoint inhibitor (ICI)-based treatments have become the mainstay of first-line treatment for unresectable hepatocellular carcinoma (HCC), but there has been a concern that intrahepatic HCC lesions may be less responsive to ICI monotherapy. We aimed to investigate the organ-specific response patterns among unresectable HCC patients treated with first-line atezolizumab-bevacizumab or lenvatinib.
methodsThis retrospective study included 386 patients with Child-Pugh A unresectable HCC who were treated with first-line atezolizumab-bevacizumab (n = 217) or lenvatinib (n = 169). The organ-specific response was separately evaluated according to the site of the lesions: liver, lung, lymph node (LN), and intraabdomen based on a radiological evaluation adopted from RECIST v 1.1.
resultsThe median age was 60 years. Hepatitis B infection was the most common etiology (n = 270, 69.9%), and 291 (75.4%) patients had a viral etiology. The proportion of patients achieving a ≥ 30% reduction in the tumor burden for each organ category was overall higher in the atezolizumab-bevacizumab group than that in the lenvatinib group: 20.2% vs. 11.8%, 23.0% vs. 12.2%, 27.9% vs. 17.9% and 33.3% vs. 15.0% for intrahepatic, lung, LN, and intraabdominal lesions, respectively. The corresponding values for the subgroup with a viral etiology were 17.3% vs. 8.1%, 18.8% vs. 13.3%, 28.9% vs. 3.6%, and 36.0% vs. 12.5%, respectively.
conclusionCompared to lenvatinib, atezolizumab-bevacizumab was associated with a favorable organ-specific response regardless of the site of the tumor lesions. Unlike anti-PD-1 monotherapy, atezolizumab-bevacizumab had a comparable organ-specific response between intrahepatic and extrahepatic lesions, especially for those with viral etiology HCCs.
