Overcoming Photodynamic Therapy Resistance: GSH‐Responsive AIE Photosensitizer‐Hydroxycamptothecin Nanoliposomes for Extrahepatic Cholangiocarcinoma
ABSTRACT Photodynamic therapy (PDT) has been shown to improve survival and quality of life in patients with unresectable extrahepatic cholangiocarcinoma. However, its therapeutic efficacy is frequently limited by the survival of residual tumor cells that can re‐enter the proliferative cycle. Our previous studies showed that residual cholangiocarcinoma cells can re‐enter the proliferative cycle following PDT accompanied by hypoxia‐induced activation of the HIF‐1α survival pathway and intracellular antioxidant progra …
