As a promising non-invasive treatment method, phototherapy has attracted extensive attention in the field of combined cancer therapy. Among various optical agents, organic ones have been considered as a promising clinical phototheranostic agent due to its high safety and non-toxic property. In addition, due to the clear structure, facile processability, organic optical agents can be easily endowed with multiple imaging and phototherapeutic functions, significantly simplifying the relatively complex system of imaging-guided combined cancer therapy. This review summarizes the recent research on organic optical agents in imaging-guided combined cancer therapy. The application of organic optical agents in a variety of combined cancer therapeutic modes guided by imaging are introduced respectively, including photodynamic and photothermal combined therapy, phototherapy-combined cancer chemotherapy, and phototherapy-combined cancer immunotherapy. Finally, the concluding remarks and the future prospects are discussed.
