Endoscopic resection (ER) safely removes early GI cancers, offering histological analysis and clear margins. High-volume centers reduce ER risks, making it a viable alternative to surgery for specific early esophageal cancers.

Area of Science:

  • Gastroenterology
  • Endoscopic Surgery
  • Oncology

Background:

  • Endoscopic resection (ER) is a safe and effective method for resecting dysplastic lesions and early carcinomas in the gastrointestinal (GI) tract.
  • ER offers advantages over other local endoscopic treatments like thermal destruction and photodynamic therapy (PDT).
  • Histological processing of resected specimens provides crucial information on invasion depth and ensures clear margins.

Purpose of the Study:

  • To evaluate the safety and efficacy of endoscopic resection (ER) for early gastrointestinal cancers.
  • To compare ER with other local endoscopic treatments and surgical resection.
  • To determine the impact of procedural volume on ER outcomes.

Main Methods:

  • Review of endoscopic resection (ER) procedures for GI tract lesions.

  • Analysis of histological data to assess invasion depth and margin status.
  • Comparison of ER outcomes with surgical resection and other endoscopic therapies, considering center volume.

    • Main Results:

    • ER demonstrates decisive advantages over thermal destruction and PDT, including histological assessment and clear margins.
    • ER morbidity and mortality are significantly dependent on the frequency of esophagectomy performed at a center.
    • Centers performing >20 procedures/year had 8% mortality, vs. 21% in centers with <10 procedures/year.

    Conclusions:

    • Curative endoscopic treatment for early esophageal carcinomas should be performed in high-volume centers, similar to surgical high-volume centers.
    • Patients with high-grade dysplasia (HGIN) or mucosal Barrett's carcinoma should undergo ER with curative intent.
    • ER is a safe and effective alternative to radical surgery for select early esophageal cancers, with comparable survival rates to the general population.
