Table 15. Published Recommendations for Diagnosis and Surveillance of Juvenile Polyposis Syndrome (JPS)

Organization/ Author SMAD4/BMPR1A Testing Recommendeda Age Screening Initiated Frequency Method Comment 
ACPGBI (2007)15–18 yb1–2 yC or FS + BESurveillance for gene carriers and affected until age 70 y and discussion of prophylactic surgery.
Cleveland Clinic (2007) [533]15 y3 yC, EGDSome families with SMAD4 mutation also have HHT; these individuals may need to be screened for HHT.
Johns Hopkins (2007) [532]Yes, genetic testing preferred over colonoscopy15 y or at onset of symptomsYearly until polyp free then every 2–3 yCProphylactic surgery if >50–100 polyps, unable to manage endoscopically, severe GI bleeding, JPS with adenomatous changes, strong family history of CRC.
St. Mark's (2012) [489]Yes, genetic testing at age 4 y12 y1–3 y based on severityC, EGDConsider HHT workup.
NCCN (2014) [92]Yes~15 y2–3 y or 1 y if polyps are foundCRefer to specialized team.

ACPGBI = Association of Coloproctology of Great Britain and Ireland; BE = barium enema; C = colonoscopy; CRC = colorectal cancer; EGD = esophagogastroduodenoscopy; FS = flexible sigmoidoscopy; GI = gastrointestinal; HHT = hereditary hemorrhagic telangiectasia; NCCN = National Comprehensive Cancer Network.
a SMAD4/BMPR1A mutation analysis includes sequencing followed by analysis for deletions (e.g., multiplex ligation-dependent probe amplification), if no mutation found by sequencing.[504]
bYounger, if patient has presented with symptoms.
