Influence of anxiety/depression on chemotherapy-induced oral mucositis and related quality of life: A prospective cohort study

The impact of anxiety and depression on chemotherapy-induced oral mucositis has not been extensively explored in the literature. The aim of the present study was to evaluate anxiety/depressive symptoms, health-related quality of life, and oral health-related quality of life and their association with oral mucositis among individuals receiving chemotherapy. This is a prospective longitudinal study carried out at a Brazilian referral service. The Hospital Anxiety and Depression Scale (HADS), World Health Organization Quality of Life-BREF (WHOQOL-BREF), and Oral Health Impact Profile questionnaire (OHIP-14) were applied at D0 (before chemotherapy) and D15 of chemotherapy. Clinicodemographic data and oral mucositis severity scores were evaluated. A total of 37 individuals (median age: 49 years) were included in the study. Nearly 38% of patients developed chemotherapy-induced oral mucositis and had higher anxiety/depression scores at baseline. Oral mucositis had a negative impact on oral health-related quality of life regarding functional limitation, physical pain, physical disability, and handicap. Anxiety/depressive symptoms are associated with oral mucositis that affects overall health and oral health-related quality of life. •Impact of oral mucositis (OM) on quality of life goes beyond oral health symptoms.•Anxious and depressive states contribute to the onset of chemotherapy-induced OM.•OM had a negative impact on oral health-related quality of life.•Monitoring mental health status and physical support in an oncology setting.
