Background: Non-operative management of early-stage polypectomy-identified colorectal cancer (CRC) may be a safe alternative, but limited data exist.
Methods: We compared outcomes between adults with post-polypectomy CRC who did and did not ultimately undergo resection from 2003 to 2018. Overall (OS) and recurrence-free (RFS) survival were calculated via log rank analysis using the Mantel-Cox method and plotted on Kaplan-Meier curves with significance evaluated at P < 0.05.
Results: N = 78 patients were included, most commonly with rectal/rectosigmoid CRC (45%). Almost half (47%) had resections, and the remaining 41 patients (53%) underwent organ-sparing techniques. Chemoradiation was administered to 5 of these 41 patients (12%), all with rectal cancer. At median follow-up of 52 months, 5-year OS and RFS were 78% and 100% with no significant differences when compared to resection (all P > 0.1).
Discussion: Using evidence-based patient selection and adjuvant therapy, organ-sparing management provides equal survival when compared to resection for post-polypectomy CRC.

Development of a National Colorectal Cancer Screening Research Agenda: An Initiative of the Canadian Screening for Colorectal Cancer Research Network (CanSCCRN).

The Canadian Screening for Colorectal Cancer Research Network (CanSCCRN) recently set out to develop a national CRC screening research agenda and identify priority research areas. The specific objectives were to (1) identify evidence gaps relevant to CRC screening and the barriers and facilitators to evidence generation and uptake by CRC screening programs, (2) establish high-priority collaborative research ideas to inform best CRC screening practices, and (3) identify one to two research topics for grant development and submission within 12 to 18 months. Three focus groups were conducted with network members and relevant parties ( = 15) to identify evidence gaps, barriers, and facilitators to evidence generation and uptake.

Background: The goal of surveillance after the endoscopic resection of colorectal tumors is to reduce colorectal cancer (CRC) incidence and mortality. Considering the effective use of the limited endoscopic capacity and the cost of surveillance, it is desirable to develop a surveillance program that is as minimal as possible. In Europe (European Society of Gastrointestinal Endoscopy [ESGE]) and the USA (Multi-Society Task Force [MSTF]), after the results of the National Polyp Study (NPS) were established, guidelines were developed that stratified risk based on initial endoscopy, and surveillance programs for each risk group were proposed.

Background & Aims: Colonoscopy-based surveillance to prevent colorectal cancer (CRC) causes substantial burden for patients and health care. Stool tests may help to reduce surveillance colonoscopies by limiting colonoscopies to individuals at increased risk of advanced neoplasia.
Methods: This cross-sectional observational study included individuals aged 50-75 years with surveillance indication.
Development and External Validation of a Prediction Model for Colorectal Cancer Among Patients Awaiting Surveillance Colonoscopy Following Polypectomy.

Background And Aims: Demand for surveillance colonoscopy can sometimes exceed capacity, such as during and following the coronavirus disease 2019 pandemic, yet no tools exist to prioritize the patients most likely to be diagnosed with colorectal cancer (CRC) among those awaiting surveillance colonoscopy. We developed a multivariable prediction model for CRC at surveillance comparing performance to a model that assigned patients as low or high risk based solely on polyp characteristics (guideline-based model).
Methods: Logistic regression was used for model development among patients receiving surveillance colonoscopy in 2014-2019.

Article Synopsis
- Prophylactic closure using clips after endoscopic resections helps decrease the risk of delayed hemorrhage, particularly for larger non-pedunculated colorectal lesions removed using electrocautery.
- Cold resections, which are less invasive and have a lower risk of bleeding, generally do not require clip closure, and audit of clip usage revealed varying and often unnecessary application for smaller lesions.
- A study involving 3,784 colorectal lesions showed that clip placement was significantly more common after electrocautery (71.1%) compared to cold resection (3.9%), indicating potential areas for improving practice and reducing waste in outpatient colonoscopy procedures.
