Despite the fact that HCC has distinct morphological and phenotypic patterns, therapeutic options are limited to comparatively homogeneous drugs such as multi-targeted tyrosine kinase blockers and immune checkpoint blockers. Multiple studies evaluating the effectiveness of different medications have yielded disappointing findings, indicating that HCC has poor immunity to chemotherapy, which is exacerbated by multidrug resistance. As a result, more successful therapies addressing HCC's disordered metabolic and molecular pathways are needed. The quite often change in sequence of genes and molecular targets in HCC patients are telomerase reverse transcriptase, Wnt/-catenin signaling pathway oncogene (CTNNB1), and the TP53 gene, according to integrated genomic profiling.
