Existing schemes of cancer combination therapy based on engineered EVs. Chemotherapy-related combination, immunotherapy-related combination, and visual therapy are three main categories. Other schemes, such as the combination of new and traditional therapy, combination of three or more drugs, are increasingly mentioned in recent studies. PDT photodynamic therapy; PTT photothermal therapy; ICI immune checkpoint inhibitors; ICB immune checkpoint blockade
