Area of Science:

  • Oncology
  • Biomarkers
  • Cell Biology

Background:

  • Carcinogenesis is associated with abnormal cell proliferation.
  • Cell proliferation has prognostic value in human tumors.
  • Proliferative abnormalities can precede morphological changes, making them potential early biomarkers.

Purpose of the Study:

  • To review methods for measuring cell proliferation in clinical samples.
  • To highlight the importance of these methods as biomarkers for chemoprevention.
  • To emphasize the need to understand the strengths and weaknesses of each technique.

Main Methods:

  • Review of techniques for assessing cell proliferation in tissue sections.
  • Includes mitosis counting, AgNORs, bromodeoxyuridine uptake, and immunohistochemistry for proteins like PCNA and Ki-67/MIB-1.
