To address these unmet needs, the investigators bring together internationally recognized scientists from genomics and immunology and established clinician investigators in a synergistic team. This TCR capitalizes on recent collaborative advances made by the PIs in the consortium. The investigators have shown through multi-region sampling of freshly resected HCC and phylogenetic analysis, that significant intra-tumoral heterogeneity exists and have identified the specific positions of known clonal drivers. Simultaneously the investigators have analyzed the immune landscape of the tumor microenvironment with deep immune-phenotyping and found unique inter-patient immune landscapes predictive of clinical trajectory.
