Oncolytic Viruses: a novel treatment strategy for breast cancer

Breast cancer, an unceasingly occurring neoplasm, is one of the major determinants of mortality in women. Several ineffective attempts have been pursued using with conventional therapies against breast cancer. Resistance to existing therapies and their respective debilitating adverse effects have led research toward a new era of cancer treatment using viruses. Virotherapy constitutes a developing treatment modality with multiple mechanisms of therapeutic activity in which the viruses can be directly oncolyticand can express transgenes or induce host immune response against tumor cells. Several different DNA- and RNA-containing viruses have been considered for virotherapy of breast cancer including adenovirus, herpes virus, vaccinia, reovirus, Newcastle Disease virus, measles virus and vesicular stomatitis virus. This review aims to summarize the viro-therapeutical agents against breast malignancies. Key Scientific Concepts of Review: In this review paper, we proposed a new strategy to virus’s combinatorial treatments using several kinds of transgenes and drugs. These recombinant viruses have provided evidence of treatment efficacy against human breast cancer
