Testing underway on vaccines to intercept brewing colon cancer before it takes root
ABC7 Los Angeles • • health
Key Points:
- Dr. Stacy Norton, who has Lynch syndrome, participated in testing a new vaccine aimed at preventing colon cancer by training the immune system to detect precancerous growths caused by genetic mutations.
- Lynch syndrome is an inherited condition affecting about 1 million Americans, significantly increasing the risk of colorectal and other cancers due to faulty mismatch-repair genes that fail to correct DNA errors.
- Early clinical trials of vaccines targeting Lynch syndrome-related cancers have shown promise, with vaccinated participants exhibiting fewer precancerous polyps and increased immune response against tumor cells.
- Additional vaccine studies are underway, including trials using mRNA technology by Moderna and another vaccine by ImmunityBio, aiming to provide more effective prevention options beyond frequent colonoscopies.
- Lynch syndrome may contribute to the rising rates of colorectal cancer in younger adults, highlighting the importance of genetic testing and early screening for those with family histories or early-onset tumors.
