Genetic Information to Inform Treatment and Screening for Prostate Cancer, GIFTS Study

OUTLINE:

Participants complete questionnaire over 20 minutes at baseline, then undergo collection of saliva sample for genetic testing. Participants identified to have an inherited mutation in a deoxyribonucleic acid (DNA) repair gene undergo genetic counseling. Participants whose genetic testing does not indicate an inherited mutation in a DNA repair gene receive a letter thanking them for their participation and emphasizing the importance of ongoing communication with their physician and family members about cancer risk. Participants may also receive an educational flyer with or without a educational video regarding prostate cancer and genetic testing.

Participants will be sent newsletters every year to encourage study engagement and update health questionnaires every two years.
