Clinical Management of HDGC

HDGC Clinical Guidelines Updated

strand of DNA

Increasing awareness of HDGC and the rapid advances in genetic diagnostic tools, endoscopic modalities, and the increasing use of laparoscopic surgery led a group of clinical geneticists, gastroenterologists, surgeons, oncologists, pathologists, molecular biologists, dietitians, and patients’ representatives from nine different countries to convene a workshop in order to update the management guidelines for this condition set in 2010 and to propose directions for future research.

The workshops were held in 2014 and 2019. Our Founder, Karen Chelcun Schreiber, had the privilege of participating in the workshops, and to represent those patients and families she has talked with and learned from over the years through her work with No Stomach For Cancer.

The new guideline was published online in August 2020 in the Lancet Oncology

The groups organize to discuss a variety of topics including genetic testing, surgery, surveillance strategies, pathology reporting, and the patient’s perspective on multiple aspects, including diet post gastrectomy.

Workshop discussions are focused on five major topics:

  • Genetic counseling and mutation analysis
  • Endoscopic surveillance and screening of cancer
  • Risk-reduction surgery of the stomach and breasts
  • Pathological specimen processing and diagnosis
  • Patients’ and dietician’ perspective

Updates and new areas addressed in the latest guideline include:
