Stand Up To Cancer (SU2C) announced today that an international team of experts will take a new approach to fighting the world's third-leading cause of cancer death -- stomach (or gastric) cancer.
Too often, gastric cancer is detected at an advanced stage, when it is very hard to treat. This new team will apply its technological prowess to the challenge of detecting gastric cancer at an early stage, potentially saving many thousands of lives."

The SU2C Gastric Cancer Interception Research Team: Early Detection and Interception of Diffuse and Intestinal Gastric Cancer was introduced at the SU2C Scientific Summit 2020, a meeting organized by the American Association for Cancer Research, SU2C's Scientific Partner, at which scientists, advocates, funders, and others hear reports on the progress of numerous SU2C-supported teams and individual researchers.
The $3 million research team will be funded over three years and is supported by generous grants from the Cless Family Foundation and Sara & Jeff Schottenstein Family Charitable Fund.
Andrew T. Chan, MD, MPH, professor of medicine at Harvard Medical School and director of cancer epidemiology at the Massachusetts General Hospital Cancer Center, will serve as leader of the SU2C Gastric Cancer Interception Research Team. The co-leader is Sandra Ryeom, PhD, associate professor of cancer biology at the University of Pennsylvania's Perelman School of Medicine. The team features researchers from the University of Chicago, City of Hope Comprehensive Cancer Center, Memorial Sloan Kettering Cancer Center and Samsung Medical Center.
The Research Team will conduct intensive studies to identify biomarkers, such as particular bits of DNA and cells that are shed from the tumor that circulate in the blood system and indicate the presence of gastric cancer.
"Gastric cancer can be a devastating diagnosis because it carries such a poor prognosis," stated Marty Cless. "After witnessing my father lose his battle with this disease, the urgency is early detection. Developing new diagnostic tools to find these cancers earlier will improve patient outcomes and change the prognosis from dire to hopeful."
"Bringing early interception to gastric cancer patients in collaboration with SU2C and the Cless family is key to help gastric patients triumph over this devastating disease," said Jeff Schottenstein. "This project honors the memory of my inspirational, kind and beautiful wife, Sara Schottenstein, who lost her battle with gastric cancer in 2016. Sara was such a warm and loving person. I am deeply touched to know that her legacy includes helping others in such a meaningful way."
In addition to U.S.-based scientists, the team includes researchers at the Samsung Medical Center in Seoul, South Korea, the country with the highest rate of stomach cancer in the world, according to the World Cancer Research Fund (WCRF).
Stomach cancer - also known as gastric cancer - is the fifth most common cancer worldwide, and third-leading cause of cancer death, according to the WCRF. Around 952,000 new cases of stomach cancer occurred around the world in 2012, accounting for seven per cent of all new cases of cancer. About 70 per cent of cases of stomach cancer occur in less developed countries with about half of all cases in Eastern Asia, particularly China.
In the United States, the rate of survival five years after diagnosis is only 32 percent, according to the National Cancer Institute. Survival rates are lower in less-developed countries, according to the WCRF. The poor prognosis is attributed largely to the fact that symptoms often appear only at a late stage in the development of the cancer.
"We have been actively involved in developing new endoscopic imaging techniques that can define areas of the stomach that are at high risk of developing cancer," Chan said. "We can also use this information to derive new blood-based biomarkers that can be used for early detection of stomach cancer."
Techniques to be explored include a tiny, pill-sized camera that can be swallowed by a patient without sedation, Chan said. This camera can provide detailed images of the lining of the stomach to identify abnormal areas that might be precancerous.
When validated in clinical trials, the refined techniques will help doctors detect precancers in populations at high risk.
The team will be the sixth SU2C team focusing on Cancer Interception, which is the concept of detecting and diagnosing cancer at a very early stage and/or developing techniques to prevent precancerous lesions from developing into full-blown cancer. Teams established earlier focus on cancers of the lung and pancreas and on multiple myeloma, a malignancy of the bone marrow.
