The Correlation of Postoperative Polyp Recurrence and Colorectal Cancer

Postoperative Endoscopic Polyp Recurrence Correlation With Pathological Status Classification of Colorectal Cancer: a Multicenter, Retrospective Cohort Open-label Study

Postoperative endoscopic polyp recurrence correlation of colorectal cancer: a retrospective cohort open-label study

This study aims to address the gaps in existing research by focusing on the high-risk group of colorectal cancer patients post-radical surgery, systematically reviewing potential factors influencing polyp recurrence, further clarifying independent risk factors for postoperative polyp recurrence in this population, and constructing a predictive model that better aligns with the clinical needs of such patients, thereby providing more precise references for developing personalized follow-up strategies in clinical practice.

Inclusion Criteria:

Patients who underwent radical surgery for colon cancer at Gansu Provincial People's Hospital from January 2015 to December 2024 and regularly completed colonoscopy follow-up after surgery were selected as the research subjects. Inclusion criteria:

Diagnosed with colon cancer through histopathological examination ; Undergoing radical R0 resection ； Complete Colonoscopy follow-up after surgery less than 12 months.

Exclusion Criteria:

With adenomatous polyposis , Lynch syndrome and Peutz-Jeghers syndrome； Combined inflammatory bowel disease; Polyp were present before surgery and have not been completely removed； With distant metastasis or local recurrence； Clinical data is missing and can not be analyzed.
