Study reveals cancer diagnosis is more deadly in blacks
A study on deaths among people diagnosed with cancer gives a grim picture of survival among African Americans, according to researchers at the University of South Carolina’s Arnold School of Public Health.
One of the nation’s first studies to track the ratio of deaths based on the incidence of specific cancers, the report in the June 1, 2009, issue of the journal Cancer yields a powerful measure of the scope of the cancer problem among men and women, whites and blacks.
Researchers examined the eight public-health regions in South Carolina for the number cancer deaths among people diagnosed with cancer from 2001 to 2005 and then compared these numbers to corresponding national rates.
Although the study was done in South Carolina, it could be replicated in other states or regions by using cancer incidence and death data, said James Hebert, the study’s lead author and a professor in the Arnold School.
Comparing and mapping race- and sex-specific cancer “mortality-to-incidence ratios” (MIR) provide a powerful method to observe the scope of the cancer problem, he said.
