Adjuvant TACE Improves Prognosis After Resection in Dual-Phenotype Hepatocellular Carcinoma: A Propensity Score-Matched Study.
Article in Journal of hepatocellular carcinoma, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 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
Background and Aims: Dual-phenotype hepatocellular carcinoma (DPHCC) is an uncommon, highly aggressive form of liver cancer defined by the concurrent expression of both hepatocellular and cholangiocytic markers. This biphenotypic nature contributes to early recurrence and significantly worse survival compared to classic HCC. The benefit of adjuvant transarterial chemoembolization (TACE) after resection for DPHCC is unclear. We aimed to evaluate whether postoperative TACE improves outcomes in patients with resected DPHCC. Methods: We retrospectively evaluated 436 patients with confirmed DPHCC who underwent curative resection from 2013-2023 at a single center. Among them, 276 received adjuvant TACE and 160 had surgery alone. To minimize selection bias, we performed 1:2 propensity score matching, yielding a balanced cohort of 210 TACE-treated patients and 134 observation-only patients. Recurrence-free survival (RFS) and overall survival (OS) were assessed with Kaplan-Meier and Cox analyses (median follow-up 58 months). Results: Adjuvant TACE significantly prolonged RFS and OS compared to observation. In the matched cohort, TACE reduced the hazard of recurrence by 32% (HR 0.678, P = 0.032) and the hazard of death by 47% (HR 0.533, P = 0.026). Multivariate analysis confirmed adjuvant TACE as an independent protective factor for RFS and OS. Toxicities were mostly mild (11.4% Grade 3-4; no treatment-related deaths). Conclusion: In patients with DPHCC, the addition of adjuvant TACE after curative resection substantially lowers recurrence rates and prolongs long-term survival. These findings support incorporating TACE into postoperative management for this high-risk HCC subtype, warranting confirmation in prospective trials. Clinical Trial Registration: This study has been registered with the Chinese Clinical Trial Registry Center (ChiCTR2500103222).
