Abstract 1248: Intralesional injection with PV-10 induces a systemic anti-tumor immune response in murine models of breast cancer and melanoma

PV-10 is a 10% solution of Rose Bengal that is currently being examined as a novel cancer therapeutic. In melanoma patients, intralesional injection (IL) of PV-10 has led to regression of injected lesions as well as distant metastases. In this study, we examined the efficacy and potential immune mechanism of PV-10 treatment in murine models of breast cancer and melanoma. In BALB/c mice bearing MT-901 breast cancer, injection of PV-10 led to regression of injected and untreated contralateral subcutaneous lesions (p
