Establishing a center of excellence for hereditary diffuse gastric cancer syndrome (2019)

“While no set of standards exist to identify centers of excellence for the treatment and study of patients with HDGC syndrome, the elements described herein can serve as a model for comprehensive, quality care.”

This topic is likely to be raised in March 2019 at the IGCLC workshop to update the HDGC Clinical Guidelines.

Here is a list of some of the medical centers known to have some level of multidisciplinary teams with HDGC expertise.

CDH1 Mutation Gene
Support for all those who carry the CDH1 gene and there family,s. Sharing your experiences with others. Letting others no how you cope without a stomach. Everyone is different. One day at a time.

CDH1 Mutation with no known family history of Gastric Cancer
This page was created to support one another and keep each other abreast of new developments in our health and testing as well as new research as it becomes available.

CDH1 Mastectomy
This group is intended for anyone with the CDH1 mutation that has had or is looking to have a mastectomy. We have found that other mastectomy pages can be very daunting and intimidating. Being a part of the CDH1 community, in other forms, has been very uplifting and we are thankful for the group we are a part of. We would like to extend that into the mastectomy portion of the CDH1 mutation.

Feel free to comment and ask questions. We like to be an open book here and encouraging to each other while on this journey we ALL never expected to be on!
