2004 NOV 4 - (NewsRx.com & NewsRx.net) -- Researchers with the U.S. National Cancer Institute (NCI) have identified time-related area socioeconomic disparities that affect cervical cancer incidence and mortality in the U.S.
"Temporal cervical cancer incidence and mortality patterns and ethnic disparities in patient survival and stage at diagnosis in relation to socioeconomic deprivation measures have not been well studied in the United States," said G.K. Singh and colleagues with the NCI's Division of Cancer Control & Population Science.
In their study, Singh and team "analyzed temporal area socioeconomic inequalities in U.S. cervical cancer incidence, mortality, stage, and survival. County and census tract poverty and education variables from the 1990 census were linked to U.S. mortality and Surveillance, Epidemiology, and End Results cancer incidence data from 1975 to 2000. Age-adjusted incidence and mortality rates and 5-year cause-specific survival rates were calculated for each socioeconomic group and differences in rates were tested for statistical significance at the 0.05 level."
The researchers observed "substantial area socioeconomic gradients in both incidence and mortality . . ., with inequalities in cervical cancer persisting against a backdrop of declining rates."
"Cervical cancer incidence and mortality rates increased with increasing poverty and decreasing education levels for the total ...
