A pan-cancer perspective analysis reveals the prognostic significance of SLC7A11 in hepatocellular carcinoma.
Article in Frontiers in oncology, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 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: The cystine/glutamate antiporter SLC7A11 is critically involved in tumorigenesis andferroptosis regulation. However, its comprehensive role in hepatocellular carcinoma (HCC) prognosis and tumor immunity remains elusive. Methods: We evaluated SLC7A11 expression using immunohistochemistry (IHC) in a clinical HCC cohort and analyzed its prognostic significance. A pan-cancer analysis across The Cancer Genome Atlas (TCGA) datasets was performed to investigate SLC7A11 genetic alterations, its impact on the tumor microenvironment (TME), tumor mutation burden (TMB), and therapy response. Results: SLC7A11 was significantly upregulated in HCC tissues, and high expression predicted poorer overall survival. Pan-cancer analysis confirmed its aberrant expression and identified a recurrent missense mutation (c.G>A) across various cancers. Elevated SLC7A11 expression correlated with higher TMB and TIDE scores, indicating a potential link to immunosuppression. It was enriched in metabolic pathways and associated with increased M0 macrophage infiltration. Furthermore, SLC7A11 expression positively correlated with response to agents including Gemcitabine and Bortezomib but conferred resistance to Cisplatin and others. Conclusion: Our findings establish SLC7A11 as a powerful prognostic biomarker for HCC, unveil its role in shaping an immunosuppressive TME, and highlight its value in predicting response to conventional and emerging therapies, providing a rationale for targeting SLC7A11 in future treatment strategies.
