Study searches for biomarkers that could identify colorectal cancer
Listen: interview about this study
A National Cancer Institute study underway at Upstate is looking for biological markers or biomarkers that signal the development of colorectal cancer the way pregnancy hormones signal a baby is growing. Leading the study are associate professors of surgery, Jiri Bem, MD, and David Halleran, MD, both of whom are colorectal surgeons.
What‘s new with this study being done at Upstate is the search for something in the blood or urine of a healthy person that could be used to reveal the presence of colorectal cancer before symptoms become apparent.
Bem says the potential is exciting, but this study is just the beginning. “This is going to be another small step toward that goal. It‘s going to take probably several years before we know what we‘ve achieved and where else we need to focus,” he says. The data collected in Syracuse will be included with data from about 5,850 other people in the United States.
Colorectal cancer is the second leading cause of cancer death in men and women combined. It has about a 50 percent mortality rate, which would be reduced if more people were screened regularly. The recommendation is every 10 years starting at age 50 for people with average risk. Experts believe 40 percent of people who should be screened, are not.
“Physicians can intervene and actually prevent the progression to a cancer,” Halleran explains. Colorectal cancers begin as benign growths called polyps. Finding polyps and removing them prevents the cancer, he says. That means undergoing colonoscopy, in which a long, thin tube is inserted through the rectum and into the colon so the doctor can visualize the inside of the large intestine. Any polyps found can be removed at the same time.
“Colonoscopy gives physicians the chance to be therapeutic as well as diagnostic.”

To join the study
Researchers from Upstate seek at least 100 Central New Yorkers to be involved in a study of biomarkers that may signal colorectal cancer. Participants will be asked for stool, urine and blood samples before undergoing colonoscopy. To be involved, a participant must:
- be between 50 and 80 years of age,
- have no symptoms of colorectal cancer,
- have no history of colorectal surgery, and
- have no cancer within the last five years.
