To date, the pathophysiologic mechanism of HFS development induced by PLD administration has not been well understood.Materials and Methods: The histological features of skin lesion in PLD-induced HFS model were characterized by hematoxylin and eosin (H&E) staining and picrosirius red staining, and the induction of inflammation and apoptosis in the epidermal layer was detected by immunohistochemical and TUNEL staining. Moreover, the generation of reactive oxygen species (ROS) was determined to elucidate the potential mechanism of skin lesion in the development of HFS.Results: The administration of PLD has been demonstrated to induce the histological damage of skin tissues including the destruction of collagen fibers and the induction of severe inflammation and apoptosis of epidermal cells. The mechanism was probably attributed to the accumulation of PLD in the skin tissues during the long-term circulation and further the induction of ROS to cause the oxidative damage of keratinocytes owing to the sustained release of doxorubicin from PLD.Conclusion: The ROS generation induced by the administration of PLD has been identified to be a crucial factor in the development of HFS, which could be used as a potential therapeutic target to alleviate the HFS symptom of PLD administration.Keywords: PEGylated liposomal doxorubicin, hand-foot syndrome, reactive oxygen species, skin lesion
