U.S. Multisociety Task Force on Colorectal Cancer releases new recommendations for hamartomatous polyposis syndrome

Bethesda, Maryland (April 26, 2022) – Gastrointestinal hamartomatous polyposis syndromes are rare, hereditary disorders associated with an increased risk of colorectal cancer. The U.S. Multisociety Task Force on Colorectal Cancer has released new guidance for the diagnosis and management of patients with rare hamartomatous polyposis syndromes with a focus on endoscopic management.

Key takeaway: The U.S. Multisociety Task Force on Colorectal Cancer recommends patients with two or more lifetime hamartomatous polyps, a family history of hamartomatous polyps, or a cancer associated with a hamartomatous polyposis syndrome in first or second-degree relative undergo genetic evaluation. If the patient and doctor determine genetic testing is warranted, it should be performed using a multigene panel test.

“Each hamartoma syndrome presents a different cancer risk and requires a different surveillance approach, making genetic testing a critical tool in cancer prevention,” says lead author Dr. C. Richard Boland, University of California-San Diego School of Medicine. “By understanding a patient’s unique genetic makeup, we can craft personalized cancer surveillance plans to prevent cancer progression and save lives.”

The 14 recommendations in this new guidance document provide genetic evaluation guidance for patients with hamartomatous polyps as well as surveillance and treatment best practices. This new guidance is provided by the U.S. Multisociety Task Force on Colorectal Cancer, which is comprised of leading experts representing the American College of Gastroenterology (ACG), the American Gastroenterological Association (AGA) and the American Society for Gastrointestinal Endoscopy (ASGE).

ABOUT HAMARTOMATOUS POLYPOSIS SYNDROMES

Gastrointestinal hamartomatous polyposis syndromes are rare, autosomal dominant disorders, meaning one mutated gene is inherited from one parent. These syndromes are associated with an increased risk of gastrointestinal and colonic polyposis, colon cancer, and other extraintestinal manifestations and cancers. Hamartomatous polyposis syndromes include Peutz-Jeghers syndrome, juvenile polyposis syndrome, the PTEN hamartoma tumor syndrome (including Cowden’s syndrome and Bannayan-Riley-Ruvalcaba syndrome), and hereditary mixed polyposis syndrome.

ABOUT COLORECTAL CANCER

Colorectal cancer, the second leading cause of cancer death in the U.S., is preventable when precancerous polyps are found and removed before they turn into cancer. With routine colorectal cancer screening, more than one-third of colorectal cancer deaths can be avoided. Screening for average-risk patients is recommended to begin at age 45, and earlier for patients with risk factors or family history. To learn more, access patient education from the GI societies: ACG, AGA and ASGE.
