More Children Die of Cancer in Low-Income Countries

Don’t Forget About the Children

By Uduak Thomas, M.A.

An article that appeared in Nature News recently highlighted a series of four studies covering various aspects of pediatric cancer that were published in The Lancet Oncology journal. According to these studies, 94 percent of children worldwide aged 0-14 years who die from cancer are in low- and middle-income countries with the usual suspects — poverty, few health-care providers, weak health systems, and poor access to education, modern technology, and health care — named as the culprits. That’s a very different picture from high-income countries where childhood cancer survival rates stand at about 80 percent, according to the researchers.

It’s quite clear why children in high-income countries do better than their counterparts in resource limited settings. There’s more research that’s done here and abundant financial and human resources that has been poured into cancer studies and treatment development. A simple Google search today will yield all sorts of scientific efforts in the US and other countries of the first world that focused on fighting pediatric cancers. One example is a joint effort of the National Cancer Institute and the Cancer Therapy Evaluation Program dubbed Therapeutically Applicable Research to Generate Effective Treatments, or TARGET, initiative, which is using genomics technologies to identify biomarkers that could be used to develop new and more effective treatments for childhood cancers such as acute lymphoblastic leukemia and neuroblastoma.

Other efforts by the NCI and CTEP include the Children’s Oncology Group, an international consortium which develops and coordinates cancer clinical trials at more than 200 member universities and hospitals in the US, Canada, Europe, and Australia involving over 5,000 cancer researchers. There are also several excellent hospitals in the developed world such as the Children’s Hospital of Philadelphia and Dana-Farber Cancer Center/Boston Children’s Hospital that make it easier to get children dealing with cancer the help they need.

 

Now, do a second Google search this time for cancer research in the third world and you’ll find next to nothing being done at the local level — what little there is mostly being conducted by scientists from higher-income countries. That’s not to say that there aren’t praiseworthy efforts going on at the global level. One of these is the International Confederation of Childhood Cancer Parent Organizations (ICCCPO), which initiated the International Childhood Cancer day on February 15 to raise worldwide public awareness of childhood cancer; and continues working to improve access to treatment and care for children with cancer globally.  Another organization is the International Cancer Center, Mahatma Gandhi Memorial Medical Trust, in India, which combines radiation therapy with public health education about cancer prevention.

Meanwhile, the World Health Organization’s International Agency for Research on Cancer is also paying attention. They are working on a document that will provide data on cancer incidence in children and adolescents from around 200 areas worldwide. It’s also working with the Automated Childhood Cancer Information System (ACCIS) to do comparative analyses of cancer incidence and survival in European children and adolescents; and with the European Network for Cancer Research in Children and Adolescents (ENCCA) to explore the possibility of collecting clinically relevant information from population-based cancer registries. They eventually hope to be a resource for researchers and public health policy-makers on incidence, mortality, and survival data for childhood cancer.

The benefits of pediatric cancer research and changes in health policies will eventually make their way down to poorer nations of the earth but that’s going to take awhile. Children in countries in much of Africa, Asia, even parts of Europe that don’t have access to these treatments and who cannot afford the costs of care and treatment cannot wait.

In their paper, Pritchard-Jones et al offer some suggestions for short term improvements. They write that in poorer countries the priority should be “to improve access to an affordable, best standard of care in each country.”

“Every country should have a national cancer plan that recognizes the unique demographic characteristics and care needs of young people with cancer,” they said.

Furthermore, “referral routes and care pathways must take account of the large geographical distances between many patients’ homes and treatment centers, and the economic, cultural, and linguistic diversity of the populations served,” they said.

For their part, Magrath et al write that more public education, better-trained health professionals, locally relevant research, regional hospital networks, international collaboration, and health insurance are factors that need to be addressed.
