Major advances have been performed in the understanding of genomic dysregulation of hepatocellular carcinoma. A median of 40 to 60 somatic mutations in coding sequence per tumor was identified including 2 to 6 mutations per tumor in genes driving liver carcinogenesis. The main genetic alterations target the key signaling pathways of liver carcinogenesis : telomere maintenance, cell cycle gene, Wnt/beta-catenin pathway, epigenetic modifier gene, oxidative stress pathway, AKT/mTOR and Ras/Raf MAP kinase pathways. A genotype/phenotype classification between these genetic drivers the tumor and patient's features have been also described and was correlated with transcriptomic profiling. These data will be helpful to identify subgroups of HCC that will respond or resist to systemic treatments already used in clinical practice such as tyrosine kinase inhibitors, anti-VEGFR antibody or checkpoint inhibitors and will be useful to identify new therapeutic targets tested in future clinical trials.

The present study was conducted to evaluate the prevalence of the signaling pathways mutation rate in the Gastrointestinal (GI) tract cancers in a systematic review and meta-analysis study. The study was performed based on the PRISMA criteria. Random models by confidence interval (CI: 95%) were used to calculate the pooled estimate of prevalence via Metaprop command. The pooled prevalence indices of signal transduction pathway mutations in gastric cancer, liver cancer, colorectal cancer, and pancreatic cancer were 5% (95% CI: 3-8%), 12% (95% CI: 8-18%), 17% (95% CI: 14-20%), and 20% (95% CI: 5-41%), respectively. Also, the mutation rates for Wnt pathway and MAPK pathway were calculated to be 23% (95% CI, 14-33%) and 20% (95% CI, 17-24%), respectively. Moreover, the most popular genes were APC (in Wnt pathway), KRAS (in MAPK pathway) and PIK3CA (in PI3K pathway) in the colorectal cancer, pancreatic cancer, and gastric cancer while they were beta-catenin and CTNNB1 in liver cancer. The most altered pathway was Wnt pathway followed by the MAPK pathway. In addition, pancreatic cancer was found to be higher under the pressure of mutation compared with others based on pooled prevalence analysis. Finally, APC mutations in colorectal cancer, KRAS in gastric cancer, and pancreatic cancer were mostly associated gene alterations.
