Young patients with sporadic colorectal adenomas: current endoscopic surveillance practices and outcomes.

BACKGROUND AND AIMS

For young individuals (age <40 years) without strong family histories that would put them at risk for genetic colorectal cancer syndromes, it is unclear if national Multi-Society Task Force surveillance recommendations apply or if endoscopists follow these guideline recommendations when such patients are incidentally found to have adenoma(s) on colonoscopy.

METHODS

We reviewed records on young (age <40 years) patients, with either no family history or only a moderate family history (1 first-degree family member with colorectal cancer at age ≥50), who were found to have neoplastic polyp(s) on their index colonoscopy. We assessed the pattern of endoscopist surveillance recommendations, whether endoscopist recommendations complied with national guidelines, and compliance with surveillance recommendations.

RESULTS

One hundred forty-one subjects were included, of whom 19 (13.5%) had a moderate family history of colorectal cancer. For patients with non-high-risk findings, 27.7% were asked to repeat their colonoscopy in ≤3 years and 99.0% within 5 years. Endoscopist surveillance recommendation compliance rates with national guidelines were >65.0% for low-risk neoplasia but lower for high-risk (40.0%), nonpolypoid (44.2%), and serrated neoplasia (54.2%, P < .001 for all). Subjects whose endoscopist recommendations were noncompliant with guidelines were usually recalled too early (96%). Only 24.7% of subjects were actually compliant with endoscopist surveillance recommendations.

CONCLUSIONS

For young patients with neoplastic polyp(s) but no strong family history, most endoscopists complied with national guidelines and recommended repeat colonoscopy in 3 to 5 years. However, relatively few patients were compliant with repeat colonoscopy recommendations. For most cases that were noncompliant with guidelines, patients were recalled too early as opposed to too late.
