Cancer gene therapy is reshaping oncology by addressing disease at the genetic, cellular, and immune-system levels rather than relying solely on cytotoxic intervention. The field spans ex vivo and in vivo gene delivery, viral and non-viral vectors, gene-modified cell therapies, oncolytic viruses, RNA-based approaches, tumor suppressor replacement, immune checkpoint modulation, and genome-editing-enabled strategies. Clinical momentum is supported by advances in vector engineering, improved manufacturing controls, companion diagnostics, biomarker-guided patient selection, and expanding regulatory experience with advanced therapy medicinal products. The most active areas include hematologic malignancies, where engineered immune cells have demonstrated durable responses in selected patient populations, and solid tumors, where innovation is focused on overcoming tumor heterogeneity, immune suppression, delivery barriers, and antigen escape. For healthcare systems, cancer gene therapy presents a dual imperative: accelerating access to potentially transformative treatments while managing complex requirements for cold chain logistics, long-term follow-up, pharmacovigilance, specialized clinical infrastructure, and value-based reimbursement. As oncology shifts toward precision medicine, gene therapy is becoming a critical pillar in the broader cancer treatment continuum, linking molecular diagnostics, individualized treatment design, immune engineering, and real-world evidence generation.

The cancer gene therapy landscape is undergoing a structural transition from experimental intervention to clinically integrated precision oncology. The first major shift is the diversification of therapeutic platforms, with engineered T-cell therapies, tumor-infiltrating lymphocyte approaches, oncolytic viral therapies, gene-silencing technologies, and genome editing advancing in parallel. This diversification is reducing dependence on a single modality and encouraging combination strategies with checkpoint inhibitors, targeted therapies, radiation, and conventional chemotherapy. The second shift is the evolution of delivery science. Improved lentiviral, retroviral, adenoviral, adeno-associated viral, lipid nanoparticle, and polymer-based delivery systems are being optimized for payload capacity, tissue tropism, immunogenicity, persistence, and manufacturing scalability. The third shift is the move toward earlier-line use and broader tumor coverage, supported by biomarker enrichment and adaptive trial designs. Regulators are increasingly emphasizing potency assays, comparability protocols, long-term safety monitoring, and post-authorization evidence, reflecting the complexity of living and gene-modifying therapies. Manufacturing is also transforming, with closed-system processing, automation, decentralized production models, and quality-by-design practices reducing variability and strengthening supply resilience. Together, these changes are repositioning cancer gene therapy as a precision, platform-based discipline where clinical outcomes depend on the integration of molecular biology, immunology, manufacturing science, digital analytics, and health system readiness.

Artificial intelligence is increasingly influencing cancer gene therapy across discovery, development, manufacturing, clinical deployment, and post-treatment monitoring. In discovery, machine learning models are used to identify tumor-associated antigens, predict neoantigen immunogenicity, prioritize genetic targets, design guide RNAs, optimize vector payloads, and model off-target effects. In translational research, AI supports multi-omics integration across genomics, transcriptomics, proteomics, single-cell sequencing, spatial biology, and clinical datasets, helping researchers understand tumor microenvironments and resistance mechanisms. In clinical development, AI-enabled patient stratification can improve trial enrichment by aligning molecular profiles with therapy mechanisms, while synthetic control methods and real-world data analytics may strengthen evidence generation where randomized trials are challenging. Manufacturing is another critical application area, as AI can monitor process parameters, predict batch variability, support release testing, and improve autologous cell therapy scheduling. In clinical practice, AI-driven decision support can help interpret complex molecular reports, assess eligibility, forecast toxicity risk, and personalize monitoring for cytokine release syndrome, neurotoxicity, immune escape, and relapse. The cumulative impact of artificial intelligence is not the replacement of scientific and clinical judgment, but the acceleration of evidence-based decision-making in a field defined by biological complexity, individualized production, and high-stakes therapeutic decisions. Responsible adoption requires validated algorithms, transparent data governance, bias mitigation, cybersecurity, interoperability, and regulatory alignment.
