Adjuvant PD-1 inhibitors improve recurrence and survival outcomes in high-risk hepatocellular carcinoma patients after curative hepatectomy.
Article in European journal of medical research, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers, 1 of them a synthesis that pooled it.
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
backgroundHepatocellular carcinoma (HCC) is the most prevalent malignancy in China, with liver resection recognized as the primary curative intervention. However, HCC patients face an elevated risk of recurrence, thereby significantly impacting prognosis. PURPOSE: This study aimed to assess the impact of adjuvant programmed cell death protein-1 (PD-1) inhibitors on survival outcomes in patients with HCC who are at high risk for postoperative recurrence following curative hepatectomy. MATERIALS AND
methodsAmong the 199 study participants, 77 received adjuvant PD-1 inhibitors. Propensity score matching (PSM) was used to balance baseline differences between patients who received adjuvant PD-1 inhibitors and those who did not. Assessment of overall survival (OS) and recurrence-free survival (RFS) was conducted using Kaplan-Meier curves, while Cox regression analysis was employed to identify prognostic factors influencing survival.
resultsAfter PSM, the 1-year and 2-year RFS were 87.1% and 74.2% in the PD-1 inhibitors group and 44.6% and 37.8% in non-PD-1 inhibitors group (p < 0.001). The 1-year and 2-year OS were 98.5% and 95.7% in the PD-1 inhibitors group compared with 90.7% and 77.0% in non-PD-1 inhibitors group (p = 0.004). Multivariable analyses demonstrated that the use of adjuvant PD-1 inhibitors was significantly associated with improved RFS and OS. Subgroup analysis indicated that adjuvant PD-1 inhibitors group achieved longer RFS than the non-PD-1 inhibitors group in patients without adjuvant transarterial chemoembolization (TACE).
conclusionThe administration of adjuvant PD-1 inhibitors may effectively reduce the risk of tumor recurrence and improve survival in HCC patients with high risk of recurrence after curative hepatectomy.
