Benefits of colonoscopic surveillance after curative resection of CRC

290 patients, median time of follow-up, 20m Follow-up colonoscopies recommended at 6-month or 1-year

intervals 31 (10.7%) of patients were diagnosed subsequently with

intraluminal recurrence 21(67,7%) of recurrences occurred within 2 years 45.2% (14p) of the recurrences were intraluminal 38.7% (17p) were asymptomatic at the time of the detection

Metachronous neoplasms occur in 2,1% with median time of the diagnosis 128 months

In 66,7% of the diagnosed recurrences, asymptomatic In 88,3% of patients, no curative second-look surgery The rate of discovered metachronous tumors was similar,

irrespective of the follow-up regimen

Resectability of LR

75% of curative resections in patients with asymptomatic LR 15,8% of curative resections in patients with symptomatic LR

Conclusion

Earlier diagnosis of the recurrence may increase likelihood of the cure

Aggressive colonoscopic surveillance in the first two years
