Therapeutic Effects of Bovine nterovirus Infections on Autochthonous Rat Ovarian Carcinomas Induced by 7, 12-dimethylbenz (a) anthracene (DMBA)

Abstract

It has been previously reported that infection by a bovine enterovirus (MZ-468), which does not infect normal human cells, was remarkably effective for the therapy of adult T cell leukemia (ATL) in experimental rabbit models (Shingu et al. 1991). Therapeutic treatment studies were performed twice on 30 and 20 autochthonous rat ovarian carcinomas induced by DMBA. The average tumor size of the virus treatment group was significantly smaller than the control group when analyzed by a nonparametric Mann-Whitney method (p<0.06 and 0.002 for the 1st and 2nd experiments, respectively). These results indicate that an enterovirus infection may be clinically useful for the therapy of human ovarian cancers with bad prognoses.
