USMSTF Guidelines for follow-Up after Colonoscopy and Polypectomy in colorectal cancer
U.S. Multi-Society Task Force on Colorectal Cancer (USMSTF) has released its updated guidelines for Polypectomy Surveillance. This is an update to a 2012 guideline. The objective is to update the 2012 recommendations for follow-up after colonoscopy with or without polypectomy in average-risk individuals. The guidelines have been published in the journal Gastroenterology.
Colonoscopy is performed routinely for colorectal cancer (CRC) screening, follow-up of other abnormal screening tests, workup of signs and symptoms of gastrointestinal disease, and surveillance after CRC and polyp removal
This document is based on recent evidence regarding the effect of screening and surveillance on incident colorectal cancer (CRC) and polyp risk, in the era of heightened focus on the importance of high-quality colonoscopy and broader use of technological advances.
Key Recommendations are
- The recommendations assume high-quality baseline colonoscopy, defined as complete examination to the cecum, adequate bowel preparation, a performance by a colonoscopist with adequate adenoma detection rate, and attention to complete polyp excision.
- The individuals with normal colonoscopy, or with <20 hyperplastic polyps <10 mm, should undergo surveillance in 10 years.Individuals with 1–2 adenomas <10 mm should undergo surveillance colonoscopy in 7–10 years. In those with 3–4 adenomas <10 mm, surveillance should occur in 3–5 years.
- Individuals with 5–10 adenomas, adenoma ≥10 mm, or adenoma with villous component or high-grade dysplasia should undergo surveillance in 3 years.
- Patients with >10 adenomas should return for surveillance in 1 year, with consideration for genetic testing based on adenoma burden, age, and family history.
- In the case of piecemeal resection of adenoma ≥20 mm, surveillance colonoscopy should occur in 6 months, then 1 year later, then 3 years after the second examination.
- Individuals with 1–2 sessile serrated polyps (SSPs) <10 mm should undergo surveillance colonoscopy in 5–10 years. In those with 3–4 SSPs <10 mm or hyperplastic polyp ≥10 mm, surveillance should occur in 3–5 years.
- Individuals with 5–10 SSPs, SSP ≥10 mm, SSP with dysplasia, or traditional serrated adenoma should undergo surveillance in 3 years.
This USMSTF 2020 guideline has added granularity that allows for more personalized recommendations, particularly for patients with small polyps.
