Antitumour treatments are evolving, including bacteria-mediated cancer therapy which is concurrently an ancient and cutting-edge approach. Salmonella typhimurium is a widely studied bacterial species that colonizes tumor tissues, showing oncolytic and immune system-regulating properties. It can be used as a delivery vector for genes and drugs, supporting conventional treatments that lack tumor-targeting abilities. This article summarizes recent evidence on the anticancer mechanisms of S. typhimurium alone and in combination with other anticancer treatments, suggesting that it may be a suitable approach to disease management.
Keywords: bacteria-mediated cancer therapy (BMCT); bacterial delivery vector; bactofection; combination therapy; tumor therapy.
