Purpose: Chemotherapy-induced mucositis is a prevalent and burdensome toxicity among adolescent and young adults (AYAs) with cancer and impedes the delivery of optimal therapy. Its development is not well understood, but baseline stress and inflammation may be contributory factors. This pilot study evaluates stress and inflammation as risk factors for mucositis, identifies effect size estimates, and evaluates the feasibility of a prospective study to investigate mucositis development. Methods: Thirty AYAs receiving chemotherapy with substantial risk of mucositis completed baseline stress measures, and serum was collected for inflammatory biomarker analysis. Regression and mediation analyses determined the relationship between stress/inflammation and mucositis. Results: Stress appears to be a significant risk factor for incidence of mucositis (odds ratio 1.13, p = 0.125) and predicts total mucositis score (β = 0.281, p = 0.023) as well as peak incidence (β = 0.052, p = 0.018). Baseline levels of interleukin (IL)-1a and epidermal growth factor (EGF) predicted mucositis development, and EGF and IL-8 may mediate the relationship between stress and mucositis. Findings suggest that stress-induced inflammation exacerbates symptom development. Conclusion: Results from this pilot study inform mucositis symptom models, suggesting that psychosocial and physiologic factors are involved in development. Importantly, this pilot study provides initial effect size estimates, including magnitude and direction of relationships, that are essential to informing larger, more robustly powered studies. High enrollment, low attrition, and minimal missing data in this study suggest this model is feasible for research in this population. Importantly, this work is a first step in identifying new risk factors for mucositis and targets for nurse-led interventions to prevent toxicity development.
