A team of
Cleveland Clinic researchers have found that regular screening for Lynch Syndrome, the top genetic cause of adult colon cancer, can significantly reduce the occurrence of subsequent cancers. Researchers screened all colorectal cancers surgically removed at the Clinic for Lynch Syndrome and referred those who tested positive to genetic counselors.
Lynch Syndrome affects patients at an early age and often leads to multiple colorectal cancers. Women are additionally more susceptible to uterine and ovarian cancers. By identifying the disease early, people with Lynch and their families can work with their doctors and counselors to keep an eye on signs of early cancers.
The research was led by Charis Eng, Hardis Chair and founding director of the Cleveland Clinic
Lerner Research Institute’s
Genomic Medicine Institute. The findings were published in the online
Journal of Clinical Oncology.
“This paper shows successful implementation of a rapid, cost-effective system-wide screening to detect potential Lynch syndrome,” says Eng. “Because of this research, we know how to catch these things early and how to prevent them. If you are positive for Lynch, cancer can occur as young as age 25 and you should get a colon screening every year, and women should also get uterine screenings.”
Eng says patients with Lynch Syndrome can then weigh the surgical options when they are diagnosed with colon cancer. Patients may opt to have the entire colon removed, and women may opt to have the uterus and ovaries removed as well, to prevent future cancers.
“Instituting high risk surveillance early routinely saves lives,” Eng says. "It is an extreme challenge to bring genomics research to successful implementation in genomic medicine practices,” says Eng. “Here, we have achieved 100 percent successful implementation of universal Lynch syndrome screening.”
