Area of Science:

  • Gastroenterology and Oncology
  • Preventive Medicine
  • Cancer Screening

Background:

  • Colorectal cancer (CRC) mortality is best reduced through screening for colorectal neoplasia.
  • Current screening methods like fecal occult blood tests and endoscopy face compliance challenges.
  • Emerging technologies like colonography and fecal DNA testing are not yet suitable for population screening.

Purpose of the Study:

  • To review current strategies for colorectal cancer screening and diagnosis.
  • To discuss advances in the prevention and management of colorectal adenomas and cancer.
  • To evaluate the effectiveness and limitations of various diagnostic and surveillance methods.

Main Methods:

  • Review of current literature on colorectal cancer screening, diagnosis, and prevention.

  • Analysis of new findings regarding aspirin's role in adenoma recurrence.
  • Evaluation of dietary factors, biomarkers, and endoscopic surveillance techniques.

    • Main Results:

    • Long-term aspirin use shows preventive effects on adenoma recurrence, though optimal dosage and mechanism (involving cyclooxygenase-2) require further study.
    • Low fiber intake, not low folate consumption, is associated with adenoma risk.
    • Endoscopic surveillance remains suboptimal, prompting efforts to reduce endoscopy frequency and pathologist workload.

    Conclusions:

    • Fecal occult blood test programs combined with endoscopy are crucial for CRC mortality reduction.
    • Selective diagnostic strategies aim to minimize unnecessary procedures for symptomatic patients.
    • Advances in surgery, radiotherapy, and interventional endoscopy (argon plasma coagulation, metal stents) improve rectal and colonic cancer management.
