BACKGROUND: Photodynamic therapy (PDT) is a therapeutic intervention that can be applied to cancer treatment. The interaction between a photosensitizer (PS), ideal wavelength radiation, and tissue molecular oxygen triggers a series of photochemical reactions responsible for producing reactive oxygen species. These highly reactive species can decrease proliferation and induce tumor cell death. The search for PS of natural origin extracted from plants becomes relevant, as they have photoactivation capacity, preferentially targeting tumor cells and because they do not present any or little toxicity to healthy cells.
OBJECTIVE: Our work aimed to carry out a qualitative systematic review to investigate the effects of curcumin (CUR), a molecule considered as PS of natural origin, on PDT, using red light or near-infrared radiation in tumor models.
METHODS: A systematic search was performed in three databases (PubMed, Scopus, and Web of Science) using the PICOT method, retrieving a total of 1,373 occurrences. At the end of the peer screening, 25 eligible articles were included in this systematic review using inclusion, exclusion, and eligibility criteria.
RESULTS: CUR, whether in its free state, associated with metal complexes or other PS and in a nanocarrier system, was considered a relevant PS for PDT using red light or near-infrared against tumoral models in vitro and in vivo, acting by increasing cytotoxicity, inhibiting proliferation, inducing cell death mainly by apoptosis, and changing oxidative parameters.
CONCLUSION: The results found in this systematic review suggest the potential use of CUR as a PS of natural origin to be applied in PDT against many neoplasms, encouraging further search in PDT against cancer and serving as an investigative basis for upcoming pre-clinical and clinical applications.
