ABSTRACT

The management of hepatocellular carcinoma (HCC) faces substantial and evolving challenges, driven by its aggressive biology, drug resistance, and the clinical urgency to detect recurrence. The treatment paradigm has undergone a profound transformation, evolving from surgical interventions and molecular targeted agents to the current era dominated by immunotherapy. Immune checkpoint inhibitors, particularly when used in combination with anti-angiogenic drugs or as part of dual-checkpoint blockade regimens, have established a new first-line standard of treatment for advanced HCC, delivering unprecedented survival improvements. Despite this progress, significant obstacles remain, including primary and acquired resistance, variable patient responses, and notably reduced efficacy in specific etiological subgroups. This comprehensive review synthesizes the emerging modalities such as bispecific antibodies, adoptive cell therapies, and innovative rational combinations that integrate systemic immunotherapy with locoregional treatments or novel targeted agents. Furthermore, we delve into the critical search for predictive biomarkers, encompassing liquid biopsy and multi-omics approaches, and dissect the complex cellular and molecular mechanisms underlying therapeutic resistance within the immunosuppressive tumor microenvironment. Finally, we outline future translational directions, emphasizing the expansion of immunotherapy, the development of tailored strategies for therapy-resistant disease, and the imperative move towards a personalized, biomarker-driven treatment framework. This review provides a cohesive overview of the field and charts a roadmap for future research to overcome the current challenges in HCC immunotherapy.

ABSTRACT

Lung cancer remains the leading cause of cancer-related mortality, yet current precision oncology approaches remain overwhelmingly tumor-centric, guided by genomic alterations and immune biomarkers, while largely neglecting the profound impact of aging biology on treatment response. While emerging evidence suggests that aging biology can modify therapeutic benefit and toxicity, its clinical integration remains uneven and largely investigational. In this review, we explicitly distinguish the chronological aging from biological aging to clarify how host biology modifies therapeutic benefit and toxicity. We synthesize mechanistic, translational, and early clinical evidence, while explicitly noting areas where prospective validation is lacking, to reframe personalization of lung cancer therapy through an age-conscious lens. We summarize data indicating that immunosenescence is associated with T-cell exhaustion, myeloid dominance, and extracellular matrix stiffening, features that may contribute to immune-evasive tumor phenotypes and attenuated responses to immune checkpoint blockade in subsets of patients, while pediatric cases, though rare, illustrate how global precision initiatives like iTHER and ZERO enable cautious adaptation of adult therapies. Moving beyond chronological age, we discuss biological age biomarkers, including PhenoAgeAccel, epigenetic clocks, telomere length, and frailty indices, which outperform traditional metrics in predicting risk, resistance, and toxicity, and propose integrating these tools into trial design, screening, and care planning which show promise for risk stratification and toxicity prediction but are not yet validated for routine treatment selection. Looking forward, we outline investigational strategies at the intersection of geroscience and oncology, including immune engineering, senolytics, microenvironmental modulation, and AI-driven multi-omic modeling. Overall, this review argues that biological age represents a critical but still underdeveloped dimension of precision oncology, and highlights key evidence gaps that must be addressed before age-aware personalization can be implemented in routine lung cancer care.

ABSTRACT

The prognosis for hepatocellular carcinoma remains grim. Combining radiotherapy with immune checkpoint blockade (ICB) has shown potential to enhance therapeutic outcomes, yet there is a pressing need for further advancements. Our previous research demonstrated that this combined approach suppresses ALKBH5 gene expression and increases m6A modification levels in hepatocellular carcinoma tissues. High-throughput sequencing and detailed molecular analysis revealed that inhibiting ALKBH5 amplifies CIITA m6A modifications post-therapy. This modulation triggers MHC II molecule expression in tumors, facilitating the presentation of tumor-associated antigens to CD4 + T lymphocytes and the recruitment of CD8 + T cells for an anti-tumor immune response. Building on these findings, we engineered a CIITA vector with a specific site mutation to confirm that the regulation of CIITA by the combined radiotherapy and immunotherapy is mediated through m6A methylation. Consequently, we established a comprehensive network involving ALKBH5, CIITA, MHC II, and CD4+ and CD8 + T cells. To elucidate the role and underlying molecular mechanisms of this combined therapy in reshaping the tumor immune microenvironment for hepatocellular carcinoma, we employed multi-omics approaches across in vitro, animal model, and clinical multi-dimensional studies, offering novel insights for enhancing treatment efficacy.
