Endoscopy·2004

Area of Science:

  • Gastroenterology
  • Oncology
  • Preventive Medicine

Background:

  • Colonoscopy is superior to barium enema for neoplasia detection, but surveillance programs remain inadequate.
  • Virtual colonoscopy's diagnostic accuracy is under evaluation, with its clinical role yet undefined.
  • Screening with fecal occult blood testing (FOBT) significantly reduces colorectal cancer mortality and incidence.

Purpose of the Study:

  • To review current evidence on colorectal cancer screening methods.
  • To define the optimal role of various screening modalities in clinical practice.
  • To discuss emerging techniques and chemopreventive strategies for intestinal neoplasia.

Main Methods:

  • Review of prospective trials and feasibility studies on colorectal cancer screening.

  • Evaluation of diagnostic accuracy for virtual colonoscopy.
  • Analysis of chemopreventive studies on dietary factors, aspirin, and NSAIDs.

    • Main Results:

    • FOBT screening reduces mortality and incidence; precursor lesion removal is beneficial.
    • Sigmoidoscopy alone may be suboptimal but can complement FOBT.
    • Aspirin and NSAIDs show chemopreventive effects in early carcinogenesis; fiber supplementation's role is uncertain.

    Conclusions:

    • FOBT is effective for population screening; molecular stool screening is experimental.
    • Colonoscopy is best reserved for high-risk individuals, not initial screening.
    • Genetic markers and public information services are crucial; new endoscopic techniques are advancing care.
