Area of Science:

  • Gastroenterology
  • Oncology
  • Public Health

Context:

  • Colorectal cancer incidence and age of diagnosis are changing globally.
  • The Chinese population is experiencing increased life expectancy.
  • Early detection methods for colorectal cancer are vital.

Purpose:

  • To analyze the incidence of colorectal cancer in subjects over sixty years old.
  • To assess the effectiveness of fiberoptic colonoscopy in early cancer detection.
  • To highlight the rising median age of colorectal cancer diagnosis.

Summary:

  • A study of 4595 subjects from 1981-1988 found 476 colorectal cancers.
  • In individuals over sixty (692 subjects), 164 (23.7%) colorectal cancers were detected.
  • The median age of colorectal cancer diagnosis has risen by 7 years.
  • Cancer of the ascending colon was more prevalent (8.5%) in those over sixty.
  • A significant misdiagnosis rate of 75.6% was observed in elderly patients.

Impact:

  • Recommends fiberoptic colonoscopy for early colorectal cancer detection in the elderly Chinese population.
  • Emphasizes the need for improved diagnostic accuracy in older adults.
  • Contributes to understanding demographic shifts in colorectal cancer.
