Stereotactic body radiation therapy combined with cadonilimab and lenvatinib in the treatment of hepatocellular carcinoma with Vp3 or Vp4 portal vein tumor thrombus: a prospective, multicenter, single-arm, phase II clinical trial.
Trial report in Frontiers in immunology, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to trial NCT06040177 (Efficacy and Safety of SBRT Combined With Cardonilizumab and Lenvastinib in the Treatment of Unresectable Hepatocellular Carcinoma With Portal Vein Tumor Thrombus#a Prospective, Multicenter, Single-arm Clinical Study), which is not on this map.

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.

Abstract
Background: Hepatocellular carcinoma (HCC) patients with portal vein tumor thrombus (PVTT) exhibit a dismal prognosis, occurring in 44%-62.2% of cases at initial diagnosis. The optimal treatment for this population remains undefined. Methods: In this prospective, multicenter, single-arm phase II trial across three Chinese centers, eligible HCC patients with Vp3/4 PVTT received combined stereotactic body radiotherapy (SBRT), cadonilimab, and lenvatinib. Primary endpoint was objective response rate (ORR) in primary liver lesions (RECIST v1.1/mRECIST); secondary endpoints included ORR in PVTT, progression-free survival (PFS), overall survival (OS), duration of response (DOR), and safety. Results: Of 24 enrolled patients, 21 were evaluable for efficacy. ORR for primary lesions was 38.1% (RECIST v1.1) and 47.6% (mRECIST), with a disease control rate (DCR) of 100% by both criteria. For PVTT, ORR and DCR were 76.2% and 100%, respectively. At a median follow-up of 19.7 months, median PFS was 6.8 months (95% CI: 4.6-12.9), DOR was 10.4 months (95% CI: 2.9-NE), and OS was 13.4 months (95% CI: 6.8-NE). Early biomarker declines (≥75% AFP reduction or ≥50% PIVKA-II decline at 6 weeks) correlated with superior outcomes: AFP reduction predicted longer PFS (HR=0.22, p=0.006) and OS (HR=0.25, p=0.024); PIVKA-II reduction similarly predicted PFS (HR=0.28, p=0.007) and OS (HR=0.18, p=0.002). Common treatment-related adverse events (TRAEs) included hypertension (50%), thrombocytopenia (42%), and fatigue (38%). Conclusions: The combination of SBRT, cadonilimab, and lenvatinib showed promising efficacy and manageable toxicity in HCC patients with Vp3/4 PVTT. Early AFP or PIVKA-II response at 6 weeks may serve as a prognostic biomarker. Clinical Trial Registration: ClinicalTrials.gov, identifier NCT06040177.
