Increased Risk of Colon Cancer in HDGC Patients

Posted by Karen Chelcun Schreiber On January - 30 - 2010

The following is an excerpt from the as yet unpublished Cambridge meeting. The paper has just been accepted by the Journal of Medical Genetics and will be published early in the new year.

“There is also emerging evidence for an increased risk of colon cancer in HDGC families, and these colon cancers can display signet ring cell features (personal communications David Huntsman and Paul Pharoah). In CDH1 families in which colon cancer is reported information should be collected concerning the age at diagnosis, whether the affected member(s) are first or second degree relatives and whether the pathology was mucinous or showed signet ring cells. Depending on these factors enhanced screening should be considered with colonoscopy beginning at age 40 or 10 years younger than the youngest diagnosis of colon cancer, whichever is younger, and repeated at intervals of 3-5 years. It is imperative that data on colonoscopic screening in these individuals is collated so that these guidelines can be evidenced based in the future”.

Hereditary Diffuse Gastric Cancer (HDGC)

Posted by Karen Chelcun Schreiber On January - 29 - 2010

Gastric cancer is the second most common cause of cancer-related death in the world.

The American Cancer Society estimated that 21,500 new cases of stomach (gastric) cancer would be diagnosed in the United States in 2008.1 Because gastric cancer is difficult to diagnose, it is often discovered in patients at a late stage with a poor prognosis. The treatment for gastric cancer is surgery and chemotherapy;2 however, the overall 5-year survival rate is low, at 24.3%.1

It is estimated that 1-3% of cases of gastric cancer are caused by Hereditary Diffuse Gastric Cancer.2 Hereditary diffuse gastric cancer (HDGC) is an inherited cancer syndrome that leads to an increased risk for both diffuse gastric cancer and lobular breast cancer in women. Patients who inherit the genetic mutation for HDGC are at high risk for developing gastric cancer at a young age.3 Read the rest of this entry »

Watch the video about Mapping the Human Genome and Stomach Cancer.

“Good Morning America” considers the discovery of genetic markers such as the one causing HDGC to be one of the top medical advances of the decade. Stomach cancer is mentioned specifically in this video from December 29, 2009 featuring Dr. Tim Johnson’s descriptions of medical breakthroughs. We are confident that the efforts of all of us impacted by HDGC and other diffuse gastric cancers, have already resulted in this national coverage: one small step in educating the world, on our journey to prevent gastric cancer and ultimately to find a cure!

HDGC Research: In pursuit of stomach cancer prevention

Posted by Karen Chelcun Schreiber On November - 11 - 2009

A  prestigious James Cook Fellowship has been awarded to researcher Parry Guilford, University of Otazo, New Zealand, to pursue innovative research aimed at reversing or preventing the very early stages of stomach cancer.

Read Parry Guilford’s personal post detailing his exciting research plan for HDGC / CDH1 gene research.  His two year fellowship will begin in March, 2010.

The James Cook Fellowship provides funding for two years of concentrated research, free of teaching and administrative commitments.  My planned research is built broadly around establishing methods to assess individual risk of developing gastric cancer.  As we all know, CDH1 mutation carriers have a lifetime risk of around 70-80% of developing diffuse gastric cancer, but we have little understanding of an individual’s actual risk at any particular point in time. A better understanding of this would help individual carriers decide what the best time for surgical intervention is.  Read the rest of this entry »

CDH1 gene mutation causes stomach cancer: How is it inherited?

CDH1 Mutations and Inheritance

By Amy Stettner, MS, CGC
Genetic Counselor
Madison, WI

Our bodies are made up of trillions of tiny cells. We have skin cells, muscle cells, bone cells, stomach cells, etc. Each cell contains a copy of our genetic code. This genetic code is made up of DNA and is packaged into structures called chromosomes. Read the rest of this entry »

HDGC and the Increased Risk of Lobular Breast Cancer

Posted by Johanna Chelcun On August - 25 - 2009

by Johanna Chelcun, MHS, PA-C

 

Scientific Background

The role of the E-cadherin protein affected by CDH1 gene mutations is adhesion of adjacent cells in certain tissues of the body.   In patients with a CDH1 gene mutation, the loss of E-cadherin is thought to lead to invasive tumors, most often in the lining of the stomach.  However, a form of breast cancer called lobular breast cancer has also been associated with the CDH1 gene mutation and hereditary diffuse gastric cancer.

Lobular breast cancer caused by CDH1 mutations cause cancerous cells to be scattered throughout the breast tissue, making the cancer difficult to diagnose (much like hereditary diffuse gastric cancer).  Additionally, the same type of cancer cells, called signet ring cells, are found in both lobular breast cancer and diffuse gastric cancers.  This helps to solidify a relationship between the CDH1 gene mutation and an increased risk of both diffuse gastric cancer and lobular breast cancer.  To date, lobular breast cancer is the only cancer besides gastric that is known to occur at increased rates in families affected by a CDH1 gene mutation.

TV New Zealand Close Up: The Kiwis who inspired a Grey’s plot

Posted by Karen Chelcun Schreiber On June - 14 - 2009

View an uplifting and interesting Close Up news broadcast about Hereditary Diffuse Gastric Cancer (HDGC) on TV New Zealand featuring Parry Guilford, the scientist who first identified HDGC and the CDH1 gene mutation that causes HDGC.  His discovery, only eleven years new, has been saving so many lives, including in the Chelcun family and many other families worldwide.  The Close Up includes interviews with the original families in whom HDGC was first identified.  We must find ways to fund the promising research that will ultimately lead to the prevention of this particular cancer as well as other related cancers.

New Zealand Listener, Interview with Parry Guilford

Posted by Karen Chelcun Schreiber On June - 10 - 2009

When the hospital drama Grey’s Anatomy screens on June 14 (in New Zealand), there will be a ripple of pride through the corridors of Otago University’s Cancer Genetics Laboratory.  That’s because one of the main storylines in the episode - a family grappling with the terrible consequences of inherited stomach cancer - has its origins in a 1998 discovery by researchers at the laboratory, let my Oamaru-raised geneticist Parry Guilford.

      Thank you so much for your message Cecily. I think it is just amazing that we can ‘chat’ to others just like ourselves, even if we are oceans apart. I still feel amazed at how well my recovery has gone thus far and it is just lovely to read other personal stories that reassure me [...]
