Brain cancer survival in Kentucky: 1996-2000

Abstract

This is a report of brain cancer survival patterns in certain Area Development Districts (ADDs) in Kentucky, the state, and the nation. Brain cancer is of national and regional concern as it is a disease of high case fatality rates and relatively short survival. Comparisons for survival were made between the U.S.A. and the state. Kentucky has higher brain cancer mortality rates than the U.S.A., but significantly better cause-specific survival (p < 0.05). In order to examine within state variations for brain cancer survival, data organized for the fifteen ADDs from the state's central cancer registry were used. The analytic focus of this analysis were three regions expressly: the Purchase ADD (location of the Paducah Gaseous Diffusion Plant), the Green River ADD (the location of elevated brain cancer mortality rates), and the Kentucky River ADD (comprising counties that each have significantly more than the state average of persons living below the national poverty level). We found no evidence of lower survival for brain cancer among the poorer region of the state. The western districts were found to have lower cause-specific survival than the state (p < 0.05) and the U.S.A. Such a regional variation alerts population-based researchers to consider varying survival trends within the state's population.
