• To highlight the potential of oncolytic viruses as targeted cancer immunotherapeutics.

Main Methods:

• Review of existing literature on oncolytic virotherapy.
• Analysis of preclinical studies involving oncolytic virus platforms.
• Examination of clinical trial data for oncolytic virotherapy efficacy and safety.

Main Results:

• Oncolytic viruses demonstrate tumor specificity and induce cancer cell lysis.
• Engineered viral vectors show improved tumor targeting, spread, and gene delivery capabilities.
• Oncolytic virotherapy exhibits potential in modulating the tumor microenvironment and eliciting in situ vaccination effects.

Conclusions:

• Oncolytic virotherapy is a rapidly advancing field with significant therapeutic potential in oncology.
• Further research and clinical studies are crucial for optimizing oncolytic virus design and application.
