Rural and urban kids in U.S. have same cancer survival odds

"The widespread availability of public health insurance for children and adolescents and a nationwide network of pediatric cancer providers" may be why.

Living in a rural or urban area at the time of a cancer diagnosis has no impact on a child’s chance of survival, a new study shows.

“The widespread availability of public health insurance for children and adolescents and a nationwide network of pediatric cancer providers may explain this finding,” says Kimberly Johnson, associate professor at the Brown School at Washington University in St. Louis, and senior author of the paper, which appears in the journal Cancer.

The researchers believe the study to be the first to examine the relationship between rural/urban residence and childhood or adolescent cancer survival in the United State.

Johnson and coauthors Arash Delavar and Qianxi Feng, recent graduates of the Brown School, obtained information from the database Surveillance, Epidemiology, and End Results 18, which compiled information for individuals diagnosed at ages birth to 19 years with a first primary malignant cancer from 2000 through 2010.

Researchers defined rural/urban residence at the time of diagnosis using Rural-Urban Continuum Codes, which the US Department of Agriculture developed.

“CHIP has been shown to decrease disparities in access to care for children living in rural areas, which may improve cancer survival.”

Among the 41,879 cancer cases examined, approximately 54.7 percent were non‐Hispanic white, 54.3 percent were male, and 90.4 percent lived in a metropolitan county.

Individuals living in non-metropolitan counties versus metropolitan counties had a similar risk of cancer death, as did those living in non-metropolitan rural counties.

“Our findings are contrary to the rural-urban disparities in survival reported among adults with cervical and lung cancer in the United States, and children with cancer in a number of other countries,” Johnson says.

Possible explanations include the high rates of health insurance among children and adolescents compared to adults and a strong pediatric oncology network of hospitals throughout the United States.

“Children and adolescents generally have greater eligibility for public health insurance, including plans under the Children’s Health Insurance Program (CHIP), which may explain why children have a much lower uninsured rate (5 percent) compared with adults (12 percent),” Johnson says. “CHIP has been shown to decrease disparities in access to care for children living in rural areas, which may improve cancer survival.”

The extensive network of pediatric cancer specialists that exists throughout the United States through the Children’s Oncology Group, a program of the National Cancer Institute, may also contribute to similar survival between rural and urban childhood cancer patients, she says.

“It has been estimated that greater than 90 percent of children and adolescents diagnosed with cancer in the United States are treated at one of the more than 200 Children’s Oncology Group-affiliated cancer centers in the United States, which helps reach children living in areas with fewer medical resources,” Johnson says.
