Research on Women's Cancers Lacking in Poor and Middle-Income Countries

Wednesday, September 02, 2015

Low- and middle-income countries (LMICs) see millions of cases of breast and cervical cancer each year, but much of the research on these diseases is based in wealthier countries that have far greater resources and treatment options available, according to a review of existing research published Sept. 1 by the CDC’s Global and Territorial Health Research Network. The network's coordinating center is based at the University of Rochester.

The research disparity means gaps in our understanding of these cancers, since they may behave differently based on patients’ geography, culture and local medical practices. Recommendations and protocols based on research conducted outside of low- and middle-income countries may or may not be practical or even possible. Without this fundamental knowledge, patients in these regions may often suffer preventable illness and death.  

 “We’re talking about many countries in sub-Saharan Africa, Latin America, Asia, Southeast Asia – in other words, most of the world,” said Timothy Dye, Ph.D., professor and associate chair of Obstetrics and Gynecology at the University of Rochester’s School of Medicine and Dentistry, and principal investigator of the CDC’s Global and Territorial Health Research Network Coordinating Center. Dye is corresponding author of the review, published in PLoSOne, a peer-reviewed, open-access resource from the Public Library of Science.

“We’re arguing for more research to be done in low- and middle-income countries so prevention and treatment strategies there can be more evidence-based,” Dye said. “Better research on breast and cervical cancer in low- and middle-income countries would help develop more effective prevention programs as well.”

Introduction of the Human Papilloma Virus (HPV) vaccine in LMICs has shifted the focus toward prevention in cervical cancer, though similar developments toward prevention of breast cancer have not been documented. For both women’s cancers, the focus on implementation science (how interventions fit within real-world public health and clinical service systems) is often lacking for low- and middle-income countries.  

“With women’s cancers continually emerging as a major contributor toward morbidity and mortality around the world, failing to address their prevention and control with research generated by and for low- and middle-income settings could lead to inappropriate recommendations based on research generated in high-income settings,” said Dye.

In recommending expansion of the research base for women’s cancers in low- and middle-income countries, the authors also stress the importance of evaluating implementation of breast and cervical cancer interventions on the ground.

“The best hope for improving cancer control in low- and middle–income countries is to make sure that what we think works toward prevention and control, actually works in the settings and circumstances faced around the world,” Dye added.

The Global and Territorial Health Research Network, or “Global Network,” is a Thematic Network of the CDC’s Prevention Research Centers Program. The Global Network’s Coordinating Center is located at the University of Rochester with participating Collaborating Centers at Yale University’s Yale-Griffin Prevention Research Center and the University of Illinois at Chicago’s Illinois Prevention Research Center. Additional authors for the study come from the University of North Carolina at Chapel Hill, the University of South Florida, the University of Hawai’i at Manoa, the University of Washington, and Centers for Disease Control and Prevention’s Division of Population Health.
