Studies have shown that African Americans have higher incidences of cancer than that of other racial/ethnic groups. They also are more likely to be diagnosed later and to die of the cancer. Compared with whites, African Americans have poorer survival rates for the 4 most common types of cancer (lung, breast, prostate, and colorectal). The ready-to-launch Detroit Research on Cancer Survivors study, funded by the National Cancer Institute (NCI), is “uniquely poised” to find out why, said Douglas Lowy, MD, acting director of NCI.
The largest such study to date will include 5,560 African American cancer survivors and 2,780 family members and will look at cancer progression, recurrence, mortality as well as quality of life for survivors and their families. The researchers will investigate the “myriad factors that may affect cancer survival,” including type of treatment, coexisting disease, genetics, social structure, support, neighborhood context, poverty, stress, racial discrimination, and literacy.
The participants are drawn from 3 counties around Detroit where about 21,000 people are diagnosed with cancer every year. The study also uses data from the Detroit area population-based cancer registry, part of NCI’s Surveillance, Epidemiology and End Results (SEER) Program. Joanne Elena, PhD, MPH, scientific program director for the grant funding the study, calls it a “great example of an efficient use of an existing structure to rapidly recruit cancer survivors into research studies.”
The grant is for $9 million over 5 years. “Investigating the complex factors that lead to disparities in cancer among underserved populations should lead to a greater understanding of the social and biologic causes of such differences,” said Robert Croyle, PhD, director of NCI’s Division of Cancer Control and Population Sciences. “And our hope is that this knowledge will lead to better outcomes.”
