Young adult survivors of childhood cancer tend to have inferior health-related quality of life (HRQOL) when compared to the general population, according to research published in the Journal of the National Cancer Institute.
Childhood cancer survivors (CCSs) ages 18 to 29 reported overall HRQOL similar to that of people from the general population who were in their 40s.
However, CCSs fared better if they did not have chronic health conditions.
“Our findings indicate survivors’ accelerated aging and also help us understand the health-related risks associated with having had cancer as a child,” said study author Lisa Diller, MD, of Dana-Farber/Boston Children’s Cancer and Blood Disorders Center and Harvard Medical School in Boston, Massachusetts.
“What’s encouraging is that the lower quality of life scores are associated with chronic disease after treatment, not with a history of pediatric cancer itself. If we can prevent treatment-related conditions by changes in the therapy we use for the cancer, then childhood cancer will become an acute, rather than a chronic, illness.”
Dr Diller and her colleagues used information from the Childhood Cancer Survivor Study to compare CCSs (n=7105) and their siblings (n=372) and information from the Medical Expenditures Panel Survey to make comparisons to the general population (n=12,803).
The researchers estimated health utility, a summary measure of quality of life, in these subjects using the Short Form-6D (SF-6D). A score of “1” indicated perfect health, and a score of “0” indicated death.
Results showed that CCSs had significantly lower SF-6D scores than the general population. The mean scores were 0.77 and 0.81, respectively (P<0.001).
But there were no clinically meaningful differences between the CCSs’ siblings and the general population. Their mean SF-6D scores were 0.80 and 0.81, respectively.
Young adult CCSs ages 18 to 29 had a mean score of 0.78, which was roughly equivalent to that reported for 40-to-49-year-old adults in the general population.
However, the presence or absence of chronic health conditions played a role in HRQOL. CCSs who reported no chronic conditions had SF-6D scores similar to the general population, with a mean score of 0.81.
But CCSs with chronic conditions had scores that matched the scores of chronically ill members of the general population. CCSs with 2 chronic conditions had a mean score of 0.77. Those with 3 or more disabling, severe, or life-threatening conditions had a mean score of 0.70.
“By enabling comparisons to the general population, our findings provide context to better understand how the cancer experience may influence the long-term well-being of survivors,” said study author Jennifer Yeh, PhD, of the Harvard T.H. Chan School of Public Health in Boston.
“This is another way to understand the health challenges survivors face and where to focus efforts to improve the long-term health and quality of life of survivors.”
