Effectiveness of Oral Cryotherapy for Oral Mucositis on Cancer Patient Undergoing Cancer Therapy: A Systematic Review

BACKGROUND: Oral mucositis is one of the complications in patients undergoing cancer therapy. Oral cryotherapy (OC) is an intervention to reduce the severity of oral mucositis.
AIM: To identify, analyze, and evaluate articles regarding the effectiveness of cryotherapy for oral mucositis in cancer patients undergoing cancer therapy.
METHODS: We performed searching on seven databases (PubMed, CENTRAL, Wiley, CANCERLIT, Science Direct, EBSCO, and SpringerLink). The investigation focused on English-language articles, intervention, or observational study reporting on the effectiveness of OC against oral mucositis in patients undergoing chemotherapy, and published between October 2015 and October 2020.
RESULTS: Eleven articles met the eligibility criteria for inclusion consisting of 5 RCTs, 3 Quasi-Experiment studies, 2 Cohort studies, and one pre-experimental study. The majority of the studies show that OC is an effective intervention to reduce the degree and severity of oral mucositis in patients undergoing cancer therapy (Hematopoietic Stem Cell Transplantation and chemotherapy).
CONCLUSION: OC is practical, low-cost, and relatively safe and can be an alternative therapy in reducing oral mucositis as a side effect of cancer therapy.
