Oncolytic viruses have the potential to powerfully and selectively kill cancer cells and have shown impressive efficacy in preclinical and clinical settings. However, their potential can be restricted by inefficient delivery into the complex tumor environment. Thus, the efficient delivery of oncolytic viruses remains a significant challenge in the field of oncology, limiting their therapeutic effect. https://www.creative-biolabs.com/oncolytic-virus/approaches-to-delivery-of-oncolytic-viruses.htm
