Ferroptosis and Photodynamic Therapy Synergism: Enhancing Anticancer Treatment.

Photodynamic therapy (PDT) is widely used in cancer treatment; however, several challenges compromise its efficiency. We propose a synergistic action between PDT and ferroptotic cell death. PDT acts as a source of reactive oxygen species for the Fenton reaction, which may reinforce ferroptosis induction and increase PDT efficacy in anticancer therapy.
