New recommendations for serrated polyposis syndrome
New consensus recommendations by the U.S. Multi-Society Task Force (MSTF) on Colorectal Cancer (CRC) address serrated polyposis syndrome (SPS), which is the most common gastrointestinal polyp syndrome yet is widely underrecognized and often goes undiagnosed. SPS is a clinical syndrome characterized by an increased number of serrated lesions and is associated with an increased risk of CRC.
The U.S. Multi-Society Task Force (MSTF) on Colorectal Cancer has issued new recommendations regarding serrated polyposis syndrome (SPS), a gastrointestinal polyp syndrome that is often underrecognized and undiagnosed. SPS is characterized by an increased number of serrated lesions, which are associated with a higher risk of developing colorectal cancer (CRC).
In their 2026 consensus statement published in the American Journal of Gastroenterology, the MSTF provides 11 evidence-based recommendations aimed at increasing awareness and identification of SPS among gastroenterologists and surgical endoscopists. These recommendations cover various aspects of SPS management, including clinical strategies for diagnosis, surgical and endoscopic treatment, CRC risk assessment, and surveillance intervals.
The task force emphasizes the importance of recognizing SPS, particularly by tracking the number of serrated polyps across multiple colonoscopies. Dr. Douglas K. Rex, the lead author of the consensus document and a representative from the American College of Gastroenterology, highlights the need for best practices in identifying serrated lesions during colonoscopy, performing endoscopic resection of these lesions, and implementing appropriate surveillance for SPS patients.
The MSTF's recommendations are based on the 2019 World Health Organization (WHO) criteria for SPS, which consider factors such as polyp size, cumulative number, and location. The guidelines favor endoscopic management, recommending clearance colonoscopy every 3-6 months and surveillance every 1-2 years, potentially extending to 3 years if the polyp burden is significantly reduced.
Additionally, the MSTF advises that first-degree relatives of individuals with SPS should undergo earlier colonoscopy screenings to detect any potential issues at an earlier stage.
