The University of Colorado invites you to take part in a research study if you have a mutation, also referred to as a variant, in the CDH1 or CTNNA1 gene.
Researchers at the University of Colorado Cancer Center are conducting a study to better understand how people with CDH1 and CTNNA1 mutations think about their risk of gastric (stomach) cancer and how they feel about the medical options available to them. The study is titled: Perceptions of Gastric Cancer Risk and Attitudes Towards Endoscopic Surveillance in Patients with CDH1 and CTNNA1 Pathogenic Variants. What you share may help improve provider knowledge, patient communication, and future research in this area.
If you choose to participate, you will be asked to complete an online survey. The survey is a self-report questionnaire and takes about 20 to 30 minutes to complete.
You can complete the survey here https://redcap.ucdenver.edu/surveys/?s=K7JJMRXC7WXYEXYP
If you have family members with a CDH1 or CTNNA1 mutation who may also be interested in participating, please feel free to forward this email and the survey link to them.
If you have questions about the study, please contact the lead investigator, Swati G. Patel, MD, MS, at 303-724-2441 or [email protected].
Thank you for considering participation in this research study.
