Each of us on the Save Our Stomachs team has had our lives, and our family’s lives, upended by HDGC. Without advancements in diagnostics and treatment, our descendants lives will also be impacted. We are motivated to make a difference for all who are now facing life with HDGC and to ensure ongoing research for the benefit of future generations.

Professor Parry Guilford in the lab

Meet Parry

Parry Guilford is a Professor of Cancer Genetics at the University of Otago, Dunedin, Aotearoa New Zealand. He completed his MSc at Otago in 1983, and his PhD at Cambridge University in 1989. He is a co-founder of the cancer diagnostics company Pacific Edge Ltd and a board member of the New Zealand Health Research Council. His research areas include the genetics and management of inherited cancers, in particular Hereditary Diffuse Gastric Cancer (HDGC). Most recently, this has focused on the identification of synthetic lethal vulnerabilities which can be exploited for the chemoprevention of HDGC. Other active research areas include the development and implementation of genomics-based cancer diagnostic tools, and the use of these technologies to reduce inequities in healthcare.

How Did We Get Here?

There is a backstory to how Save Our Stomachs came into being. The story begins with the forming of an unlikely friendship. A friendship between a New Zealand based cancer geneticist and an American patient whose life was saved when she discovered his research. A relationship of mutual respect, curiosity, and the sharing of critical information each had for the other developed, when following a stomach cancer diagnosis, Karen Chelcun Schreiber reached out to Professor Parry Guilford. Each has since expanded their service to the community of HDGC affected families in remarkable ways because of their unlikely meeting and subsequent friendship.  Here, in part, is how their meeting led to change in what patients in the U.S. and around the world would learn about HDGC, and how the Save Our Stomachs campaign came into being.

Now Is The Time


“Dear Doctors,”

I wrote, “I have read with great interest the media release of March 17, 2007 entitled ‘Stomach Cancer Discovery Gives New Hope To Families’.”

I had just figured out mine was a Hereditary Diffuse Gastric Cancer (HDGC) family, having just tested positive for a CDH1 gene mutation. I wrote an email in June 2008, three months before my preventive total gastrectomy was to take place in Boston MA.

in Looking for a miracle I wrote to the New Zealand team that discovered the connection of a CDH1 gene mutation and HDGC and published this paper. Parry Guilford, Bostjan Humar and Simon Ancelle.

I said, “I am wondering if you can provide an update on the findings of your study. Is it possible with your research that there may be an alternative course of action for me to the total gastrectomy? Since I only have three months until my surgery date, time is of the essence.”

I Was Desperate, and I Was Out of Time

I was grasping at straws, hoping for an alternative to my total gastrectomy only months away. I was on my own, with virtually no resources at that time. I found Dr. Sam Yoon, a surgeon in Boston MA who, at the time, had performed the largest series of preventive total gastrectomies for HDGC. I was #7.

 Although there was no miracle solution, what I did get from Parry was a kind, thoughtful and encouraging message with the positive outlook that I needed, and the confidence that I was making the right decision, and that I could do this.

This was the start of my passion to support HDGC research, to raise money for the work taking place in New Zealand, and to help others who may not yet know that they too are affected by this hereditary cancer syndrome. This was the start of a long journey with Parry, my lifesaver, my colleague, and best of all, my friend.

Advocacy – My Passion

I started the Chelcun Family Fund for Stomach Cancer Research, and the Be Strong Hearted website to raise awareness. That led to founding No Stomach For Cancer (NSFC), then an HDGC advocacy site, active involvement in the International Gastric Cancer Linkage Consortium (IGCLC), and the establishment of an HDGC Research Endowment Fund.

With One Foot In Today And
An Eye On The Future

I’ve been committed to working to fund this endowment for several years and realized the time to do this right is Right Now. It’s time for that miracle I was looking for 14 years ago – and it’s so, so close.

Incredibly dedicated people from all walks of life, individuals affected by HDGC and equally committed to funding the research that will bring change, have banded together to launch the Save Our Stomachs campaign.

Right now. For the present generations. For the children. For the future.

Parry Guilford was born and grew up in the South Island of New Zealand, not far from where he works today at the University of Otago in Dunedin.  The father of four grown up children, Parry spends his holiday time fishing, hiking and skiing, each with either decreasing speed, skill or success.

HDGC Patient & Research Advocate
Madison WI

Sadly, the HDGC family lost Karen to Pancreatic Cancer in 2023. She parted the earth July 3, surrounded by her loved ones. To have known Karen was a gift and a blessing. She was an advocate for and mentor to many. Her life was one of service and she will be missed dearly.  We extend our condolences to her family and loved ones. 

“While November is Stomach Cancer Awareness Month, it is always time to raise awareness.”
– Karen Chelcun Schreiber

The following is an excerpt from her obituary, followed by Karen’s own description of her life and advocacy work on behalf of families faced with an HDGC diagnosis.

“Karen lost both her mother and brother to stomach cancer, and as a result she dove headfirst into research and patient advocacy. As a founder of No Stomach For Cancer in 2009, she led the charge in advocating for proper care, preventative treatment, awareness and education about stomach cancer. She participated in the creation of international standards of care for patients with HDGC. Her impact on families across the world has earned her numerous awards and recognition for her advocacy and philanthropic work. Karen lived the last 15 years of her life without a stomach due to Hereditary Diffuse Gastric Cancer Syndrome, and she helped guide countless members of the HDGC community through the same process. Most recently, along with “Parry’s Angels” she helped found Save Our Stomachs, a campaign that provides sustainable funding for research to identify drugs that will prevent the development of this cancer and identify a better way to determine cancer risk.”

Read Karen’s full obituary on the Tributes page.


I’m an optimistic realist. I love to laugh, often at myself. I am learning how to focus on Right Now! I have the most amazing family, friends and colleagues. The silver lining of HDGC has been the people I have come to know, to help, to work with, and to love, all throughout the world.

While November is Stomach Cancer Awareness Month, it is always time to raise awareness.

In 2007, my sister Deana Hamilton Hughes passed away at 39 years old from signet ring cell gastroesophageal cancer. Following her death, I went to the doctor and had an endoscopy to make sure he didn’t see anything similar to my sister’s cancer inside my GI tract. Once I got the “no issues” message from my doctor, I never thought about it again.

Then, in early 2020, a visit to my doctor for an “early satiety” complaint turned into a Hereditary Diffuse Gastric Cancer diagnosis caused by the CDH1 gene mutation. Although she wasn’t ever tested, my sister obviously carried the gene mutation. My Mom had the gene mutation and never developed cancer that we know about. She likely received the gene mutation from her father, who had a partial gastrectomy at the Mayo Clinic, and died a few years later of stomach cancer. My cousin Ryan and his Mom (my Aunt) Kathy are the only others in the family that we know carry the CDH1 gene mutation. Ryan has two sons that are too young to be tested. Finally, Kristen and I have one son, Wyatt. Sadly, I passed the CDH1 gene mutation on to him.


My personal life mission is to love everything life delivers to me (Amor Fati) and do my best to help people I love fulfill and enjoy their own life mission.


As you might imagine, passing the gene mutation on to Wyatt was devastating to me and my family. With that in mind, I fully commit to a new personal life mission to “Save Our Stomachs”. I have other good friends (that I consider family) in our CDH1 community that share our scenario of having passed the gene mutation on to their kids.

I believe our cause may encourage you to think a bit more seriously about supporting our Foundation fund raising targets more than other causes the next year or two to help me achieve a specific goal I have set for myself.


My goal is to raise $1,000,000 dollars. $250,000 by the end of 2022, and $750,000 by the end of 2023. Here is my “Why” Statement to convince you to help me:


The cause of HDGC is my CDH1 Gene Mutation. I passed this CDH1 Gene Mutation onto my son, Wyatt Hamilton. The current protocol for Wyatt, and other patients with the CDH1 Gene Mutation, is to have a prophylactic gastrectomy between the ages of 20 and 30 years old to “most successfully prevent” getting stomach cancer. Wyatt is currently 20 years old. The urgency of my goal is immediate.

My effort right now, and for the rest of my life, is to spend my healthy days doing everything I can to save Wyatt’s stomach. I can specifically do that in two ways: (1) Fund Parry Guilford’s Otago University Research Lab with an Endowment Fund to help him continue his work, and (2) Fund Dr. Jeremy Davis at the NIH to run a new Human Clinical Trial. The Human Clinical trial is almost ready to implement, and it’s a chemo prevention drug that Parry Guilford’s Lab is working on so Dr. Jeremy Davis can “put it into production”, so to speak. This Human Clinical Trial, should Wyatt and other patients decide to enter it, could allow them to delay Total Gastrectomy for a longer period of time with more assurance cancer won’t develop while they wait.

I’m asking my friends and family to make their donations to the DLH Foundation as often as possible, and we will pass those donations through to Otago and NIH. My goal is to raise and then donate the $1,000,000 to the two recipients. I will publish the financial results as frequently as necessary.

Being a father has created an intense passion toward impacting future generations with better outcomes in regard to CDH1 mutation research and treatment. My journey started with my father being diagnosed in the late stages of hereditary diffuse gastric cancer. Like many other families, the one who gives this gift of knowledge and lifeline to the future, is usually diagnosed too late with limited treatment options followed by a bleak timeline.

I am a carrier of this gene mutation which I inherited from my father. I enrolled in a study at the National Institute of Health and began endoscopic surveillance on my stomach. During my second round of surveillance, signet ring cell adenocarcinoma was found. My stomach was removed shortly after. I know better options are on the horizon for future generations and with your help we can support the future of HDGC research.

I currently work as a rehabilitation specialist and am pursuing a doctorate in traditional Chinese medicine.

“Polly wanna cracker?” Yes, I do! Since my stomach was removed in June of 2022 due to my CDH1 genetic mutation, I have been hungry all the time! I also had my breasts removed in April of 2021. Although I am cancer-free, I am not worry-free. I have three beautiful children that could potentially carry this genetic mutation. As a retired nurse, artist, wife, and mother, it has become my mission to spread awareness about this deadly syndrome. More awareness brings more funding, research and better treatment options for everyone affected.

In 2016, at age 34, I decided to do genetic testing due to two instances of breast cancer in my immediate family. I wasn’t concerned when my doctor told me the lab was backed up and it would take a few more weeks to get the results. But on the afternoon of September 16, my doctor called to tell me I carried the CDH1 mutation—something I had never heard of. Everything snowballed from there.

Living in New York City meant I had access to Memorial Sloan Kettering and a group of CDH1 experts at arm’s length. Another genetic test confirmed the mutation. An endoscopy followed soon after, in which my doctor extracted 80~ biopsies from my stomach. A few days later, I received the call nobody ever wants to receive—cancer was found. On October 24, 2016, Dr. Vivian Strong performed a Total Gastrectomy. I was completely cured. In the fall of 2019, I had a prophylactic double mastectomy, also at MSK, by Dr. Alexandra Heerdt and Dr. Joseph Disa.

The mission of Parry Guilford’s Lab is very dear to me as I have a son who has a 50% chance of inheriting my CDH1 gene mutation and associated risks for stomach cancer.

In 2015 I not only discovered that I carry the rare genetic mutation, CDH1, but was also diagnosed with infertility. It was a blessing in disguise as I was able to genetically test my embryos and chose the ones that would not inherit the gene. Since then my life has been dedicated to raising awareness for stomach cancer. My sister Polly and I created a YouTube channel aimed at promoting a healthy lifestyle all while bringing attention to genetic mutations. I am beyond excited and proud to be representing this community and to be able to use my voice for such an important cause.
