Impact of an oral care intervention protocol on oral health outcomes in head and neck cancer patients undergoing radiation or chemoradiation therapy.

BACKGROUND

Head and neck cancer patients receiving chemotherapy and radiation therapy may experience a notable and frequently sudden decline in their oral health. These alterations include oral mucositis that develops during and shortly after treatment, candida infections, trouble speaking, difficulty eating, bleeding gums, and tissue fibrosis.

MATERIALS AND METHODS

This study aimed to determine the effectiveness of oral care intervention protocol (OCIP) on oral health and oral complications. The experimental group received a structured oral care protocol, and the control group received oral care as per the standard of care of the study setting. These patients were observed every week for up to 6 weeks until the completion of radiation therapy/chemoradiation. An experimental design using a randomized controlled trial was adopted for the study. After providing informed consent, the data were collected from 80 head and neck cancer patients.

RESULTS

The maximum number of patients, i.e., 42.5% in the experimental group and 32.5% in the control group, were diagnosed with tongue cancer. Most of the participants, i.e., 57.5% in the experimental group and 67.5% in the control group, received chemoradiation as the treatment plan. Among all the oral complications, the median days to develop mucositis (p =.015), swallowing difficulty (p =.009), and chewing difficulty (p =.032) were significantly different from those of the control, indicating that the intervention was effective. As treatment progressed over the weeks, the severity of the oral problems increased in both groups (p =.001). Compared with routine care, oral care intervention improved oral health scores among cancer patients receiving head and neck radiation therapy/chemoradiation [F (401.982), p =.001].

CONCLUSION

These data suggest that the OCIP is clinically helpful in maintaining overall oral health among cancer patients receiving head and neck radiation/chemoradiation. The OCIP effectively delays the incidence of oral complications arising from head and neck radiation therapy/chemotherapy but does not prevent them. The findings of this study can also contribute to providing evidence for the use of an oral care kit, including all evidence-based interventions for patients receiving head and neck radiation/chemoradiation.
