Persistent Symptoms,Quality of Life,and Correlates with Health Self-Efficacy in Adolescent and Young Adult Survivors of Childhood Cancer

Abstract

Purpose:

The numbers of adolescent and young adult (AYA) survivors of childhood cancer are exponentially growing. To ensure suitable services are available to meet the needs of this growing population, understanding the experience of late effects, quality of life, and potentially modifiable factors, such as self-efficacy, is required.

Methods:

AYA survivors of childhood cancer recruited through an After Cancer Therapy Service at a Children's Hospital rated their symptoms experience, quality of life, and self-efficacy using the Patient Reported Outcome Common Terminology Criteria for Adverse Events, Functional Assessment of Cancer Therapy-General (FACT-G), and Patient-Reported Outcomes Measurement Information System (PROMIS^®), respectively. Descriptive statistics were used to characterize the sample. Quality-of-life scores were compared with population norms. Regression analyses were used to explore the relationships between symptom experience, quality of life, and self-efficacy.

Results:

Thirty participants (mean age 22 ± 4.4 years) reported an average of nine symptoms as persistently experienced at moderate or higher rated intensity among participants (standard deviation ±8.7; range: 0–32; interquartile range: 2–16); over half (n = 17, 56.7%) had finished treatment 10 or more years ago. Participants scored lower on the FACT-G Physical Well-being and Emotional Well-being, and higher on Social Well-being subscales than the general population. Around two-thirds of participants were confident in their ability to self-manage their health based on their health self-efficacy score. Bivariate linear regression identified a statistically significant increase in the overall quality of life with increased self-efficacy, adjusted for age and sex (0.60, 95% confidence interval [CI] 0.30–0.90, p < 0.01). Higher symptom burden was associated with a lower overall quality of life after adjusting for age and sex (−0.95, 95% CI: −1.35 to −0.54, p < 0.001).

Conclusion:

Young cancer survivors experience a substantial number of persistent symptoms related to their cancer treatment that may negatively impact aspects of their quality of life. Health self-efficacy is a potential target for future interventions.
