Abstract
BACKGROUND
Immunotherapy presents both promises and challenges in treating hepatocellular carcinoma (HCC) due to its complex immunological microenvironment. The role of B cells, a key part of the immune system, remains uncertain in HCC.
AIM
To identify B-cell-specific signatures and reveal novel immunophenotyping and therapeutic targets for HCC.
METHODS
Using the Tumor Immune Single-cell Hub 2 database, we identified B-cell-related genes (BRGs) in HCC. Gene enrichment analysis was performed to explore the possible collaboration between B cells and T cells in HCC. We conducted univariate Cox regression analysis using The Cancer Genome Atlas liver HCC collection dataset to find BRGs linked to HCC prognosis. Subsequently, least absolute shrinkage and selection operator regression was utilized to develop a prognostic model with 11 BRGs. The model was validated using the International Cancer Genome Consortium dataset and GSE76427.
RESULTS
The risk score derived from the prognostic model emerged as an independent prognostic factor for HCC. Analysis of the immune microenvironment and cell infiltration revealed the immune status of various risk groups, supporting the cooperation of B and T cells in suppressing HCC. The BRGs model identified new molecular subtypes of HCC, each with distinct immune characteristics. Drug sensitivity analysis identified targeted drugs effective for each HCC subtype, enabling precision therapy and guiding clinical decisions.
CONCLUSION
We clarified the role of B cells in HCC and propose that the BRGs model offers promising targets for personalized immunotherapy.
Core tip: We have established a reliable B-cell-related genes (BRGs) prognostic model and novel molecular subtypes in hepatocellular carcinoma (HCC). The BRGs model revealed the immune status and personalized treatment options of HCC molecular subtypes. B cells may play a role in tumor cytotoxicity by activating CD4+ and CD8+ T cells in HCC.
