Quality of Life in Adolescents and Young Adults: The Role of Symptom Burden.

Abstract

Adolescents and young adults (AYAs) with cancer report worse health-related quality of life (HRQOL) than other age groups. Symptom burden is a modifiable predictor of HRQOL. The objective of this study was to identify which symptoms are most burdensome to AYAs with advanced cancer. In this observational study, English-speaking individuals aged 12-25 years undergoing treatment for advanced cancer completed assessments of symptom burden (Memorial Symptom Assessment Scale) and HRQOL (Pediatric Quality of Life Inventory Generic Form and Cancer Module; minimal clinically important difference 4.4). We dichotomized participants as having low (<7) or high (≥7) symptom prevalence. Mixed regression models estimated HRQOL differences between groups. For individual symptoms, unadjusted mixed models estimated HRQOL reductions. N=58 AYAs completed baseline surveys. The median age was 17 years (IQR 15-19), 58% were male, 59% identified as white, and 44% were diagnosed with leukemia/lymphoma. High symptom prevalence was associated with a mean generic HRQOL 7 points lower (95% CI: -11, -3; P < 0.01) and cancer-specific HRQOL score 12 points lower (95% CI: -17, -7; P < 0.01) than low symptom prevalence. The most prevalent symptoms were fatigue (71%), pain (58%), and difficulty sleeping (58%). Fatigue (-8), difficulty concentrating (-7), and mouth sores (-6) were associated with the greatest generic HRQOL score reductions. Dysphagia (-12), difficulty concentrating (-12), and sadness (-11) were associated with the greatest cancer-specific HRQOL score reductions. The symptom experience among AYAs with advanced cancer is unique. Separate evaluation of AYA's symptoms may optimize management and improve HRQOL.
