Abstract

We report here the efficacy of tumor-targeting Salmonella typhimurium A1-R (A1-R) on mouse models of disseminated and metastatic ovarian cancer. The proliferation-inhibitory efficacy of A1-R on human ovarian cancer cell lines (SKOV-3-GFP, OVCAR-3-RFP) was initially demonstrated in vitro. Orthotopic and dissemination mouse models of ovarian cancer were made with the human ovarian cancer cell line SKOV-3-GFP. After tumor implantation, the mice were treated with A1-R (5 × 107 colony-forming units [CFU], i.v.), and there were no severe adverse events observed. In the orthotopic model, tumor volume after treatment was 276 ± 60.8 mm3, compared to 930 ± 342 mm3 in the untreated control group (P = 0.022). There was also a significant difference in survival between treated mice and untreated mice in a peritoneal dissemination model (P = 0.005). The results of this report demonstrate that A1-R is effective for highly aggressive human ovarian cancer in metastatic and dissemination mouse models and suggest its clinical potential for this highly treatment-resistant disease.
