Therapeutic Potential of Oncolytic Viruses in the Treatment of Lung Cancer Caused by Chemical Warfare Agents: A Narrative Review.

In World War I, sulfur mustard or mustard gas was used as a chemical weapon for the first time. Years later, during the imposed war (eight years of holy defense) against the Islamic Republic of Iran, Iraq used this poisonous gas against the soldiers and people of Iranian cities. Many years after the war, many chemical veterans still suffer from its effects. Mustard gas is a strong alkylating substance with cytotoxic and mutagenic properties, which causes blisters in mucous membranes and skin when it comes in contact with the skin. It is usually a colorless or amber-yellow oily liquid. In high concentrations, it has a disgusting smell similar to horseradish, onion, or garlic, which is mostly due to contamination with ethyl sulfide and other byproducts of its synthesis. Various studies have proven that long-term exposure to this toxic gas can lead to respiratory disorders and lung cancer. Considering the drug resistance and special conditions of chemical veterans with lung cancer, one of the new methods proposed for their treatment is the use of oncolytic viruses. The purpose of this study is to review the therapeutic potential of oncolytic viruses in the treatment of lung cancer caused by chemical warfare agents. [ABSTRACT FROM AUTHOR]
