It is important to note that the relative
contribution of environmental, genetic,
and behavioral factors will be different for
each specific type of cancer and in each
individual.
It is also important to note that the
interaction between environmental,
genetic, and behavioral factors may
significantly increase the risk of cancer.

Logic Model
Common sources of data that can be
used for defining the cancer burden
•
•
•
•
Demographic data (Census U.S)
Risk factor data (BRFSS)
Incidence data (KCR)
Mortality data (State Vital Records)
Demographic (U.S. Census) data
• Covers the entire population
• Provides details on important factors that influence
the burden of cancer in a population
• Is only done once every 10 years in the U.S.
• Is difficult to determine the number of people in a
population by race and ethnicity.
CDC’s Behavioral Risk Factor
Surveillance System
•
•
•
•
Largest telephone survey in the world
Tracks many important health risks
Complex sample design
Difficult to generalize the information to small
populations
Incidence Data
• Closer in time to causal events
• Represents both occurrence and risk of getting
disease
• Difficult to get all of the cases
• Complex coding rules
• Screening effect
Mortality Data
• Very complete data
• Represents the ultimate negative health
outcome
• Far away in time from causal factors
• Care must be taken to use consolidated death
records
The C-Change Project Objectives
• Build a separate index for the burden of lung,
breast, and colorectal cancer.
• Construct the index using demographic data from
the U.S. Census; risk factor data from the BRFSS;
and incidence, stage at diagnosis, and mortality
data from the NAACCR CINA data file.
• Use the index to identify the states with the
highest disease burden for lung, breast, and
colorectal cancer.
Methodology (Approach)
• The association between the demographic, risk,
incidence, stage at diagnosis and mortality variables
were explored using bivariate regression models.
• Variables with R-Squared values .25 or greater were
used to construct the initial index for each type of cancer.
• The index was created using a simple rank sum
technique. States were ranked from the highest to lowest
cancer burden and placed into five groups with red being
the states with the highest burden of cancer and green
being those states with the lowest cancer burden.

An Example
In 2001, Kentucky had the highest colorectal
cancer incidence rate in the U.S. compared
to all of the other states
In 2001, it was also noted that Kentucky
was ranked 49th in colorectal cancer
screening compared to all other states with
the second to the lowest rate (34.7% of the
age eligible population).
Data about the burden of colorectal cancer was
assembled and presented to each of the 15 District
Cancer Councils.
Following these presentations, all 15 of the District
Cancer Councils implemented evidence-based
cancer control programs aimed at increasing
colorectal cancer screening for age eligible people
living in their District.
What happened following the implementation of
these colorectal cancer screening programs?

The increase in colorectal cancer screening
has been accompanied by a 22% decrease in
both the incidence and mortality of colorectal
cancer in Kentucky. It is important to note
that these changes are statistically significant
(P<.05). In other words, it is unlikely that
these changes happened by random accident.

A 22% reduction in colorectal cancer
incidence and mortality in Kentucky is a
significant public health success.
Working together we can make a real
difference in peoples lives.
