Changes to This Summary (02/01/2012)
The PDQ cancer information summaries are reviewed regularly and updated as new information becomes available. This section describes the latest changes made to this summary as of the date above.
Education and Counseling About Risk/Risk Communication 1
Added text 2 about a prospective study that evaluated the effects of a CD-ROM decisional support aid for microsatellite instability (MSI) tumor testing and tested a theoretical model of factors influencing decisional conflict surrounding decisions to pursue MSI tumor testing (cited Hall et al. as reference 28).
The Option of Genetic Testing 3
Added text 4 about a study that examined the interpretation of direct-to-consumer (DTC) information and found that even in a highly educated cohort, the reported ease of understanding the test results was not related to an accurate interpretation of the results (cited Leighton et al. as reference 39).
Added text 5 about a follow-up study of individuals who purchased a DTC personalized genomic risk test that found no evidence of clinically meaningful distress, health behavior change (dietary fat intake, exercise), or a statistically significant difference in screening test uptake compared with baseline measures (cited Bloss et al. as reference 41).
