Reviewing Colorectal Cancer Stage at Diagnosis Trends
Maine Cancer Registry
Registry data and Behavioral Risk Factor Surveillance System (BRFSS) data from the past decade have been used for several years to inform and motivate the Maine Cancer Consortium, cancer programs, policy makers, grantors, and citizens.
The registry reviewed colorectal cancer stage at diagnosis data in four time blocks between 1995 and 2005 and found a continuous increase in percent local stage, a continuous decrease in percent regional stage, and stable distant disease. During this same time frame, age-adjusted rates of colorectal cancer mortality declined in Maine.
BRFSS data on Maine adults aged 50 years and older showed an increase in those reporting ever having had sigmoidoscopy or colonoscopy from 42% in 1999 to 62% in 2005.
By 2004–2005, 47% of colorectal cancer in Maine was localized at diagnosis compared with 40% for the U.S. population, according to national data showing a direct relationship between stage at diagnosis and survival.
Maine Cancer Registry data were used in Maine's successful application to CDC for funding to implement colorectal cancer screening opportunities for low-income and uninsured Mainers throughout the state. The data helped identify the regions and counties where incidence or mortality are highest (which correlated with BRFSS data), suggesting where the comprehensive cancer control and colorectal cancer screening programs might focus their efforts.
