Emerging Bioengineering Approaches for Cancer and Tumor Therapy

Cancer has become a significant socioeconomic burden globally, with millions of new cases and deaths each year. The promising field of bioengineering has recently undergone significant advancements, providing new methods for combating cancer. Increasing attention has been directed toward understanding the molecular mechanisms of human diseases, supported by the availability of various genetic tools and rapid technological advancements. These developments have enabled the use of the latest gene therapy techniques for cancer treatment, including gene editing, gene deletion, and correcting defective genes through methods such as TALENs, Zinc fingers, RNAi, CRISPR, site-directed mutagenesis (SDM), and enzyme therapy to modulate catalytic activity. In addition, bioengineering vaccines like mRNA vaccines, bioinformatics, computational tools, artificial intelligence (AI), nanotechnology, and chemotherapy are emerging as significant cancer treatment strategies. Among these, gene editing and gene therapy have gained particular attention in recent years and are often used in combination with other therapeutic approaches. The engineering of enzymes and advancements in nanotechnology have also significantly progressed. AI and bioinformatics have contributed to more precise diagnosis, prediction, and prognosis, enabling tailored treatment of cancer and tumors. Imaging and radiotherapy, enhanced by AI, have improved surgical outcomes, even from remote locations. Precision oncology has emerged, using bacteria and viruses to target tumors directly. In this review, we discuss recent advancements and challenges in various cancer therapies.
