Applications of yoga in oral oncology: A systematic scoping review

BACKGROUND AND AIMS: Yoga is well‐thought‐out as an all‐inclusive approach globally and can be administered in clinical care as an integrative or alternate approach to regular treatment. Yoga exercise has been disclosed to influence remission from cancer cells over a long period of time and also reverses epigenetic alterations. Applications of Yoga in the management of oral oncology patients are scarce, hence the need for a scoping review of the literature. Hence, this study aimed to conduct a scoping review of the existing empirical evidence on the applications of yoga in oral oncology. METHODS: The review methodology was informed by Joanna Brigg's Institute guidelines for systematic scoping reviews, and the review was reported in accordance with the Preferred Reporting Items for Systematic Reviews and Meta‐Analyses extension for Scoping Reviews. Ten databases were searched. The records of all the literature retrieved from the search were imported into the Rayyan software for deduplication. After the full‐text screening, only two were found eligible for inclusion in the scoping review. Data obtained in the included literature were extracted and synthesized. RESULTS: This review found that Yoga was not significantly effective in the management of stress among oral cancer patients (p‐values > 0.04). However, it was found that Yoga significantly reduced anxiety, saliva stickiness, and episodes of falling ill (p‐values < 0.05) while it improved mental well‐being, cognitive functioning, emotional functioning, and head and neck pain of those oral cancer patients that received it (p‐values < 0.05). CONCLUSION: An integrative care approach that considers nonpharmaceutical techniques such as yoga could help to reduce care cost while improving care outcomes and quality of life of oral cancer patients. Hence, it is imperative to consider yoga along with its potential benefits, and we recommend gradual incorporation of yoga into oral cancer care.
