Abstract

Objective: We previously reported a characterisation of the hepatocellular carcinoma (HCC) immune contexture and described an immune-specific class. We now aim to further delineate the immunogenomic classification of HCC to incorporate features that explain responses/resistance to immunotherapy. Design: We performed RNA and whole-exome sequencing, T-cell receptor (TCR)-sequencing, multiplex immunofluorescence and immunohistochemistry in a novel cohort of 240 HCC patients and validated our results in other cohorts comprising 660 patients. Results: Our integrative analysis led to define: (1) the inflamed class of HCC (37%), which includes the previously reported immune subclass (22%) and a new immune-like subclass (15%) with high interferon signalling, cytolytic activity, expression of immune-effector cytokines and a more diverse T-cell repertoire. A 20-gene signature was able to capture ~90% of these tumours and is associated with response to immunotherapy. Proteins identified in liquid biopsies recapitulated the inflamed class with an area under the ROC curve (AUC) of 0.91; (2) The intermediate class, enriched in TP53 mutations (49% vs 29%, p=0.035), and chromosomal losses involving immune-related genes and; (3) the excluded class, enriched in CTNNB1 mutations (93% vs 27%, p<0.001) and PTK2 overexpression due to gene amplification and promoter hypomethylation. CTNNB1 mutations outside the excluded class led to weak activation of the Wnt-βcatenin pathway or occurred in HCCs dominated by high interferon signalling and type I antigen presenting genes. Conclusion: We have characterised the immunogenomic contexture of HCC and defined inflamed and non-inflamed tumours. Two distinct CTNNB1 patterns associated with a differential role in immune evasion are described. These features may help predict immune response in HCC.

  • Several gene signatures capturing inflamed tumour microenvironment components are associated with favourable response to immune-checkpoint inhibitors, but none has been clinically validated.

    “Several gene signatures capturing the inflamed components of the TME have been associated with a favourable response to ICIs69,72,78–81, but none has been clinically validated thus far.”

    From Adjuvant and neoadjuvant immunotherapies in hepatocellular carcinoma (2024) · cites this paper as [78]

    The Discussion (page unavailable) reports two inflammatory signatures associated with ICI response in advanced HCC, and the Results (page unavailable) find higher expression of the paper’s Inflamed signature in responders than non-responders. The paper describes a continuing need for clinically useful biomarkers, but it does not establish the categorical claim that none of these signatures has been clinically validated. (LLM, conf=0.82)

    Experimental — accuracy not yet measured
  • Patients with inflamed hepatocellular carcinomas tend to have a favourable prognosis and are the most likely to benefit from immune-checkpoint inhibitors.

    “Overall, patients with inflamed HCCs tend to have a favourable prognosis and are the most likely to have improved outcomes when receiving ICIs owing to the presence of responsive immune cells72,78.”

    From Adjuvant and neoadjuvant immunotherapies in hepatocellular carcinoma (2024) · cites this paper as [78]

    In the Results (Inflamed class; page unavailable), the Inflamed signature was higher in ICI responders than non-responders, supporting the suggestion that these tumors may benefit from ICIs. The Results (Defining inflamed and non-inflamed HCCs; page unavailable) report better survival only for the Immune Active subclass; the Immune-like subclass showed no survival difference from non-inflamed profiles, so a favourable prognosis is not established for the Inflamed class as a whole. (LLM, conf=0.88)

    Experimental — accuracy not yet measured
  • Molecular classifications have identified classes of hepatocellular carcinoma associated with ICI responsiveness (inflamed class) and ICI resistance (excluded class).

    “Molecular classifications have identified classes of hepatocellular carcinoma associated with ICI responsiveness (inflamed class) and ICI resistance (excluded class).26”

    From Pathological response following neoadjuvant immune checkpoint inhibitors in patients with hepatocellular carcinoma: a cross-trial, patient-level analysis (2024) · cites this paper as [26]

    The Results (Inflamed class; page unavailable) report that ICI responders had significantly higher expression of the Inflamed signature, supporting the responsiveness association. The Results (Non-inflamed classes; page unavailable) identify an Excluded class with low immune infiltration, but do not establish that this HCC class is associated with ICI resistance. The Introduction discusses resistance in immune-excluded tumors as evidence from other cancer types. (LLM, conf=0.86)

    Experimental — accuracy not yet measured
  • Inflamed tumours make up about 30% of hepatocellular carcinomas and show extensive immune infiltration, increased immune checkpoint expression, interferon signalling activation, and a low burden of large chromosomal alterations.

    “Inflamed tumours constitute ~30% of HCCs and exhibit extensive immune cell infiltration and immune activity, detected as increased expression of immune checkpoints (such as PD-1 or its ligand PD-L1), activation of IFN signalling and a low burden of large chromosomal alterations70,71,78.”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
