Endoscopic surveillance for colorectal cancer and its precursor lesions in Lynch syndrome; time for some policy shifts?

Based on higher precursor lesion detection and lower CRC incidences in LS individuals with a gPV in MSH6 or PMS2 under biannual endoscopic surveillance, this study supports the potential for extended surveillance intervals in the latter group. As treatment for the detected T1 CRCs varied considerably with nearly equivalent recurrence rates, in selected cases less invasive interventions for LS individuals could be considered.
