    Aims:

    The English Bowel Cancer Screening Programme (BCSP) offers individuals aged 60 to 74 years guaiac FOB testing, with an invitation for colonoscopy if positive. Post-polypectomy surveillance is performed within the BCSP for individuals within the screening age range.

    Methods:

    Details were extracted from the BSCP database for individuals who attended surveillance from the start of the BCSP in 2006 until January 2017. Data were analysed using Stata 14.

    Results:

    9742 individuals with high risk (HR) adenomas at baseline subsequently attended for 2nd surveillance (S2). In this group,

    • Of 3639 with no further adenoma at 1st surveillance (S1), 288 (7.9%) had advanced adenoma (AA) and 20 (0.5%) CRC at S2

    • Of 3347 with LR adenomas at S1, 342 (10.2%) had AA and 9 (0.3%) CRC at S2

    • Of 1533 with IR adenomas at S1, 217 (14.1%) had AA and 8 (0.5%) CRC at S2

    • Of 1223 with HR adenomas at S1, 181 (14.7%) had AA and 5 (0.4%) CRC at S2

    7822 individuals with IR adenomas at baseline attended S2.

    • Of 4342 with no adenoma at S1, 203 (4.7%) had AA and 13 (0.3%) CRC at S2

    • Of 2324 with LR adenomas at S1, 149 (6.4%) had AA and 7 (0.3%) CRC at S2

    • Of 586 with IR adenomas at S1, 47 (8.0%) had AA and 1 (0.2%) CRC at S2

    • Of 570 with HR adenomas at S1, 62 (10.9%) had AA and 1 (0.2%) CRC at S2.

    Conclusions:

    AA at S2 occurs in 7.9% – 14.7% for HR at baseline and 4.7% – 10.9% for IR at baseline. For those with a maximum risk of IR at both baseline and S1, AA occurs in ≤8.0% at S2. These findings support the discontinuation of surveillance in lower risk groups.
