The purpose of this study is to learn more about malignant colorectal polyps and the risk of the cancer remaining, coming back, or spreading after the polyp is removed. The researchers also want to understand how patients and doctors make decisions about treatment after a malignant polyp is removed. Additionally, the researcher will collect information medical records, including results from tests, imaging scans, lab work, and pathology reports. The researchers may also collect images from your colonoscopy and copies of pathology slides the polyp. The researchers will also follow the patient's health over time through regular doctor visits. If the patient does not have a scheduled visit, a member of the study team will contact the patient by phone at 1 year, 3 years, and 5 years after the patient joins the study to ask about their health.

RECRUITINGRisk of residual disease and/or recurrent disease
Residual disease analysis will be limited to patients who underwent surgery (in addition to endoscopic resection). Participants will be evaluable if they undergo adequate pathological assessment of the resected specimen.Adequate assessment is defined as histopathological evaluation of all relevant tissue specimens with a documented report. Participants with incomplete or inadequate pathological assessments will be considered inevaluable. Risk of residual disease will be estimated using the Kaplan-Meier method and reported with 95% confidence intervals. Local recurrence is defined by the reappearance of disease at or near the primary site. The date of diagnosis and anatomical site of recurrence will be documented. Distant recurrence is defined by disease spread to sites distant from the primary lesion. The date of diagnosis and specific sites involved will be documented.
