Description of Endoscopic Surveillance Adherence of Colorectal Cancer Patients Following Surgery

Aims The aim of surveillance is improvement of patient survival by early detection of recurrence or metachronous cancer. The objetive is to know the endoscopic surveillance adherence in patients undergoing surgery with curative intent for colorectal cancer at a Mexican hospital. Analize the prevalence and recurrence with the endoscopic protocol described in the literature.

Methods Retrospective and observational study. We select patients who were studied at endoscopy and oncology services at Hospital Central Norte de Petróleos Mexicanos, during January 2015 to December 2019. The analysis was descriptive with measures of central tendency for quantitative variables and frequency distribution for qualitative variables.

Results Were found 232 patients. From the final 48 patients, 50 % were female. The mean age was 69 years old. The most common site of cancer was sigmoid colon (36 %). The endoscopic surveillance was divided in 4 parts: done in appropriate time, done in unappropirate time, waiting in appropriate time, waiting in unappropriate time. About the first endoscopic control, 33 % are in a appropriate time, 6 % waiting and 27 % already done. From the patients who already gone on first surveillance control, 19 % had adenomas, regardless of abscence of tumor activity in the anastomosis. During this first control, we found 1 local recurrence and 2 metachronous cancer, the 3 patients were taken at unappropriate time of follow up, with a mean time of 36 months after surgery. 19 % of patients has the second endoscopy surveillance control; at this group, we found the second recurrence case. The third endoscopic surveillance control, was made to 6 % of patients and only 2 % had an appropriate interval time.

Conclusions We found a local recurrence prevalence of 4 %, comparable with literature and 4 % of prevalence for metachronous cancer, which is greater than described in the literature.The endoscopic surveillance for colorectal cancer is as important as screening.
