Gene therapy for cancer: present status and future perspective

Area of Science:

• Oncology
• Genomics
• Biotechnology

Background:

• Cancer is fundamentally linked to somatic genomic aberrations in host DNA.
• Recent advancements in human genomics have spurred research into genetic manipulation for cancer treatment.

Purpose of the Study:

• To explore the evolving landscape of gene therapy for cancer.
• To highlight advancements in vectors, immunomodulation, and tumor microenvironment manipulation.
• To discuss the future role of gene therapy in personalized cancer care.

Main Methods:

• Gene transfer via viral and non-viral vectors.
• Immunomodulation of tumor cells and the host immune system.
• Tumor microenvironment modification to enhance anti-tumor immunity.

Main Results:

• Newer gene therapy vectors show reduced risks of mutagenesis and immunogenicity compared to older methods.
• Modest clinical success has been achieved with manageable side effects.
• Several novel therapies like antibodies, engineered immune cells, and vaccines are in development.

Conclusions:

• Gene therapy is poised to become a crucial component of multimodality cancer treatment.
• Personalized gene therapy strategies will be tailored to individual genomic and tumor profiles.
• Future cancer care will likely integrate gene therapy with surgery, radiation, and chemotherapy.
