The Oncolytic Virus Therapy for Non-Small Cell Lung Cancer / 中国生物化学与分子生物学报

ABSTRACT

Since the oncolytic herpes simplex virus T-VEC was approved in the United States for the treatment of malignant melanoma in 2015, there has been increasing interests in the oncolytic virus therapy. The oncolytic virus therapy also occupies a certain position in the treatment research process of non-small cell lung cancer(NSCLC). Based on the rapid development of genetic engineering and protein engineering, researchers have designed many recombinant oncolytic viruses targeting various specific sites to further improve their targeting and oncolytic effect in order to alleviate symptoms and even cure NSCLC patients. This review introduces the two major classifications of oncolytic viruses, wild type and gene-edited, and how they achieve tumor lysis by specifically targeting and killing tumor cells. We focus on the research progress of oncolytic virus applied alone to treat NSCLC, or combined with chemotherapy, immunotherapies such as chimeric antigen receptor (CAR)-T cell therapy, immune checkpoint inhibitors and other current hot research to treat NSCLC. At the same time, we summarize and discuss the issue of targeted transport, which is of high concern in the academic field of oncolytic virus therapy, and point out that the use of extracellular vesicles as drug carriers has a good potential for development. Finally, we analyze the existing problems and future application prospects in the context of existing basic and clinical studies, to expend new approaches for the treatment of NSCLC, so that it is no longer limited to traditional therapies.
