Abstract

Objective

Clinical trials have explored the role of curcumin in the prevention and treatment of oral mucositis (OM) in head and neck cancer patients. To provide evidence for curcumin management of OM for clinicians, a comprehensive meta-analysis of these findings is necessary. This meta-analysis aimed to evaluate the efficacy and safety of curcumin for OM caused by radiotherapy (RT) and/or chemotherapy (CT) for head and neck cancer.

Methods

Randomized controlled trials were identified from the PubMed, Embase, Web of Science, Cochrane Library, Medline, and Google Scholar databases. RevMan 5.3 was used for statistical analysis to calculate the combined risk ratios (RRs).

Results

Six studies involving 266 patients were included. Curcumin considerably reduced weight loss (mean difference [MD] − 0.78) in both the prophylactic and therapeutic phases. When used as a preventative treatment, curcumin did not reduce the incidence of OM (RR 0.99), but it did reduce the incidence of severe OM (RR 0.44) and the mean severity of OM (SMD -1.44). Curcumin also reduced the severity of OM (MD 0.82) compared to chlorhexidine.

Conclusion

Curcumin is a safe, natural bioactive substance that can effectively prevent and treat OM in patients receiving RT and/or CT, as well as reduce weight loss.
