Lynch Syndrome tools

Tools for Bidirectional Cancer Registry Reporting to Identify Individuals at Risk for Lynch Syndrome

The following materials were developed to support state programs using bidirectional cancer registry reporting to identify individuals at risk for Lynch syndrome. State health departments are encouraged to customize the materials to meet their needs. Materials are categorized by those intended for patients and for healthcare providers, but materials may be suitable for multiple audiences. Please note that some materials will need to be filled out with state-specific information, as noted below.

Explanation of estimates

We estimated, by state, the number of persons with Lynch syndrome (LS) who could be identified by screening all persons with newly diagnosed invasive colorectal cancer (CRC). These estimates are based on the numbers of incident CRC cases reported by state cancer registries in 2010 (ref 1). To approximate the proportion of persons with CRC who could be expected to have LS, we used the estimate of 3% obtained by Moreira, et al, in a combined analysis of population-based studies in the U.S., Canada, Australia, and Europe (ref 2). To emphasize that this proportion is an imprecise approximation, we display estimates based on proportions of 2% and 4% for comparison.

Several factors that could influence these estimates have not been taken into account. These factors could include changes in state populations or CRC incidence since 2010; differences in LS prevalence among different racial and ethnic groups, which vary in their distribution among the states; and errors or uncertainty in the data used to calculate the estimates.
