Comparing two techniques for removing certain colon and rectum tumors

Official title: Recurrence Rate After Endoscopic Resection of , Laterally Spreading Tumor Granular Type (LST-G) of the Colon and Rectum: Endoscopic Mucosal Resection (EMR) vs. Endoscopic Submucosal Dissection (ESD): A Multicenter Randomized Controlled Trial ( ESD vs EMR )

Run by Azienda USL Reggio Emilia - IRCCS · NCT06815406 · Data updated 2026-11-12

This study is testing which of two techniques for removing certain colon and rectum tumors works better to prevent them from coming back in patients with larger lesions.

Is this trial a fit for you?

Likely a good fit

Ideal candidates are adults aged 18 and older diagnosed with LST-G tumors larger than 20mm in the colon or rectum.

Probably not a fit

Patients with non-granular type tumors, certain lesion characteristics, or chronic inflammatory bowel diseases may not benefit from this study.

What this trial studies

This study evaluates the recurrence rates of Laterally Spreading Tumors - Granular Type (LST-G) in the colon and rectum after two different endoscopic removal techniques: Endoscopic Mucosal Resection (EMR) and Endoscopic Submucosal Dissection (ESD). EMR is a common method that may lead to higher local recurrence due to piecemeal resection, while ESD allows for complete removal in one piece, potentially reducing recurrence rates but requiring more skill and time. The study aims to determine which technique is more effective in preventing tumor recurrence in patients with LST-G lesions larger than 20mm. Participants will be monitored for recurrence rates post-procedure to assess the efficacy of each method.

Why it matters

Potential benefit: If successful, this study could lead to improved treatment options for patients with LST-G tumors, reducing the risk of cancer recurrence.

How similar studies have gone: Previous studies have shown promising results with ESD in reducing recurrence rates for similar lesions, indicating that this approach may be effective.
