Adult survivors of childhood cancer have a greater cumulative burden of chronic health conditions than the general public, according to research published in The Lancet.
The study showed that, by age 50, childhood cancer survivors (CCSs) had experienced, on average, 17.1 chronic health conditions, and matched control subjects had experienced 9.2.
“The cumulative burden of chronic disease revealed in this analysis, along with the complexity and severity of chronic conditions some survivors experience, found childhood cancer survivors to be a vulnerable, medically complex population,” said study author Nickhill Bhakta, MD, of St. Jude Children’s Research Hospital in Memphis, Tennessee.
For this study, Dr Bhakta and his colleagues assessed the lifelong impact of 168 chronic health conditions—such as hepatic, thyroid, ocular, and reproductive disorders—on CCSs and control subjects.
The 3010 evaluable CCSs had survived 10 years or longer from their initial cancer diagnosis and were 18 years or older as of June 30, 2015. The 272 controls had no history of pediatric cancer and were matched to CCSs by age and sex.
At age 50, the cumulative incidence of chronic health conditions (of any grade) was 99.9% in CCSs and 96.0% in controls (P<0.0001). The cumulative incidence of grade 3 to 5 chronic health conditions was 96.0% and 84.9%, respectively (P<0.0001).
The cumulative burden for CCSs was 17.1 chronic health conditions, including 4.7 that were grade 3 to 5. For controls, the cumulative burden was 9.2 chronic health conditions, including 2.3 that were grade 3 to 5 (P<0.0001 for both comparisons).
The researchers said second neoplasms, spinal disorders, and pulmonary disease were major contributors to the excess total cumulative burden observed in CCSs. However, there was “notable heterogeneity” in burden according to the patients’ primary cancer diagnosis.
For instance, growth hormone deficiency was in the top 10th percentile of chronic health conditions for survivors of acute lymphoblastic leukemia but not for controls.
And pulmonary function deficits were in the top 10th percentile for survivors of acute myeloid leukemia and Hodgkin lymphoma but not for controls or survivors of acute lymphoblastic leukemia or non-Hodgkin lymphoma.
“This study found that the average childhood cancer survivor has a cumulative burden of chronic disease that requires a significant time investment by healthcare providers to disentangle and manage—time that community providers are unlikely to have,” Dr Bhakta said.
“The results suggest that childhood cancer survivors may benefit from the integrated, specialized healthcare delivery that is being tried for individuals infected with HIV or those with other complex, chronic health problems.”
