Bacterial cancer therapy: A turning point for new paradigms.

Cancer treatments have advanced considerably in recent years, appreciably enhancing the quality of life and survival of cancer patients. However, standard cancer treatments still have limitations that must be improved. In recent years, bacteria-based cancer therapy has gained much more attention owing to its unique properties that are unachievable with standard therapeutics. Bacteria species such as Salmonella, Clostridium, and Listeria have been shown to control tumor growth with improved prognosis in experimental animal models and clinical settings.
