Tumors were established by injection of 106 U87 cells into the right caudate nucleus of BALB/c nude mice. Mice were randomly assigned to either MV-CEA treatment (1.8 × 106 TCID50), UV-inactivated MV-CEA treatment, or remained untreated. Significant prolongation of survival was observed in the mice treated with MV-CEA, as compared to mice that received UV-inactivated MV-CEA or no treatment (p = 0.02).
