ReviewNatural and genetically engineered viral agents for oncolysis and gene therapy of human cancers.
Based on personal acquaintances and experience dating back to the early 1950s, the senior author reviews the history of viral therapy of cancer. He points out the difficulties encountered in the treatment of human cancers, as opposed by the highly successful viral therapy of experimentally maintained tumors in laboratory animals, especially that of ascites carcinomas in mice. A detailed account of viral therapy of human tumors with naturally oncolytic viruses follows, emphasizing the first clinical trials with viral oncolysates. ⋯ The facts strongly support the conclusion that viral therapy of human cancers will remain in the front lines of modern cancer therapeutics. It may be a combination of naturally oncolytic viruses and wild-type viruses rendered oncolytic and harmless by genetic engineering, that will induce complete remissions of human tumors. It may be necessary to co-administer certain chemotherapeutic agents, advanced cancer vaccines, or even immune lymphocytes, and targeted therapeuticals, to ascertain, that remissions induced by the viral agents will remain complete and durable; will co-operate with anti-tumor host immune reactions, and eventually will result in cures of advanced metastatic human cancers.
