Efficacy Analysis of “T+A” Therapy in Different Treatment Populations of HCC

2024.01.08
Hepatocellular carcinoma (HCC) is the most common type of primary liver cancer. Most patients are unable to undergo surgical resection at the time of diagnosis, making systemic therapy an important treatment approach for this group. The combination immunotherapy of Atezolizumab plus Bevacizumab (“T+A”) has become the new first-line standard treatment for unresectable HCC patients due to its significant improvement in overall survival (OS) compared to sorafenib. However, its effectiveness in different populations, including HCC patients with different etiologies, Child-Pugh B grade HCC, and intermediate-stage HCC beyond the up-to-seven criteria, remains unclear. The journal "Hepatology Digest" has reviewed recent studies on this topic for the benefit of readers.

T lymphocytes play a crucial role in human adaptive immunity by recognizing antigens major histocompatibility complex (MHC) molecules through specific T-cell receptors (TCRs) on their surface. 95% of T cells have TCRs composed of α and β peptide chains connected by disulfide bonds, forming an α/β heterodimer. Each chain consists of constant and variable domains. TCR diversity arises from the rearrangement of the variable (V), diversity (D), and joining (J) gene segments of the peptide chains, along with random nucleotide additions or deletions.
