Pre-surgical oncolytic virotherapy improves breast cancer outcomes.

ABSTRACT

Oncolytic viruses (OVs) are a novel class of cancer biotherapeutics with the ability to kill cancers and trigger anti-tumor immunity. Using murine models of cancer in pre-clinical proof-of-concept studies, we found that neoadjuvant OV administration before surgery efficiently prevents relapse, controls metastases and sensitizes tumors to immune checkpoint inhibitors (ICIs).
