Prognostic Significance of Liquid Biopsy-Detected Genetic Alterations in Hepatocellular Carcinoma.
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. Not yet cited in PubMed.
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: Hepatocellular carcinoma (HCC) is a leading cause of cancer-related mortality worldwide and is increasingly diagnosed in younger populations. Conventional biopsy techniques can be invasive and may not accurately capture tumor heterogeneity. Liquid biopsy, analyzing circulating tumor DNA (ctDNA), offers a minimally invasive and dynamic alternative for detecting genetic alterations critical to early diagnosis and personalized treatment strategies. Methods: We analyzed serum-derived ctDNA from 20 HCC patients to identify genetic variants using next-generation sequencing (NGS). Mutations in key oncogenes and tumor suppressor genes (eg, KIT, FGFR1, FGFR3, EGFR, BRAF, FBXW7) were evaluated for their association with clinical outcomes, including tumor size, metastasis, and overall survival. Statistical analyses were performed using SPSS (v.30), with survival curves assessed via the Kaplan-Meier method. Results: Of the 20 patients (mean age 64.8±13.1 years), 35% had detectable ctDNA mutations. The most frequently observed alterations were in KIT (28.6% of ctDNA-positive patients), followed by FGFR1, FGFR3, EGFR, BRAF, and FBXW7. Patients harboring FGFR1 and FGFR3 mutations exhibited the poorest survival (3 and 7 months, respectively). Conversely, one patient with a BRAF mutation showed prolonged survival (60 months), and KIT mutations were linked to comparatively better outcomes. Overall, ctDNA-positive patients demonstrated shorter mean survival (22.5 months) than ctDNA-negative patients (35.7 months). Conclusion: Liquid biopsy-detected genetic alterations correlate with clinical outcomes in HCC, underscoring the prognostic value of ctDNA analysis. Mutations in FGFR1 and FGFR3 were associated with aggressive disease, suggesting these pathways as potential therapeutic targets. Integrating liquid biopsy with other diagnostic modalities may enhance personalized management and improve prognosis for patients with HCC.
