Overcoming barriers, addressing challenges
Investigators are also making headway in proving that collecting social determinants of health (SDoH) data during existing clinical trials is easily achievable.
Past Children’s Oncology Group trials have collected only race, ethnicity, insurance, and zip code data as proxies for exposure to adverse SDoH. Dr. Winestone and her colleagues recently investigated the feasibility and acceptability of the first COG trial to prospectively embed SDoH data collection.
Of eligible participants, 360 of 413 opted-in to the embedded SDOH aim across 101 COG sites (87.2% consent rate). Among participants, 316 surveys (87.8%) were completed a median of 11 days post enrollment, according to the findings, which were presented at the ASCO annual meeting.
“We’ve come to realize the importance of the social determinants of health [as it pertains] to outcomes, but it has been a process to learn how to effectively collect that data in a large collaborative environment,” said Dr. Winestone. “This abstract demonstrates that patients are very willing to provide this data, and they’re able to do it in an efficient way. People think of these questions as very sensitive and that families may not want to share the answers, but this study demonstrates those presumptions are false.”
The authors hope the findings fuel incorporation of SDoH data collection in future National Clinical Trials Network trials to inform impactful health equity research.
While such research and intervention efforts are gaining momentum, challenges to do the work remain. A lack of research funding and support are among the obstacles, Dr. Winestone said.
To date, much of pediatric cancer work has focused on developing new therapeutic approaches to reach a cure for more patients, she explained.
“While that’s incredibly essential, if we’re creating these approaches that only work for a subset of patients that have resources, we’re contributing to the inequities in the system,” Dr. Winestone said. “Really, [we need] dedicated support to studying how to make sure the interventions we know are effective are reaching all populations, and that the patients are poised to benefit from those interventions by setting them up for success.”
A strong research infrastructure exists to evaluate and support clinical drug trials in pediatric oncology, but the same does not exist for health equity interventions, Dr. Bona adds. A significant question that needs to be addressed is how best to integrate health equity evaluation into existing infrastructure or whether to build a parallel infrastructure.
Despite the challenges, Dr. Bona believes now is exactly the right time to investigate and intervene in poverty as a risk factor for childhood cancer relapse and outcomes. What has led to success in childhood cancer is how pediatric oncology has collaborated across the country to operate clinical drug trials at various centers, all in the same way, to identify which treatments work best, she said.
“We have an opportunity now in pediatrics to take advantage of this highly successful clinical trials research infrastructure to integrate interventions to address disparities in a way that has not been done previously,” she said. “The opportunity to significantly improve survival in childhood cancer by reducing disparities exists if we take this head on from a research and funding perspective and approach social risk factors just as we already know how to approach tumor genomic risk factors.”
