Paper Abstract
Background: Squamous cell carcinoma (SCC) is a common skin cancer and its treatment is still difficult. The aim of this study was to evaluate the effectiveness of nanoparticle (NP)-assisted ALA delivery for topical photodynamic therapy (PDT) of cutaneous SCC.
Methods: UV-induced cutaneous SCCs were established in hairless mice. ALA loaded polylactic-co-glycolic acid (PLGA) NPs were prepared and characterized. The kinetics of ALA PLGA NPs-induced protoporphyrin IX (PpIX) fluorescence in SCCs, therapeutic efficacy of ALA NP-mediated PDT, and immune responses were examined.
Results: PLGA NPs could enhance PpIX production in SCC. ALA PLGA NP mediated topical PDT was more effective than free ALA of the same concentration in treating cutaneous SCC.
Conclusion: PLGA NPs provide a promising strategy for delivering ALA in topical PDT of cutaneous SCC.
