Molecular testing aids cancer diagnosis, but histopathology remains key. DNA microarrays reveal gene expression profiles, improving cancer subtyping and patient outcomes, especially in prostate cancer research.

Area of Science:

  • Oncology
  • Molecular Biology
  • Genomics

Background:

  • Current cancer diagnosis and prognosis largely depend on histopathological data.
  • Molecular testing is increasingly utilized but requires integration with morphological findings.
  • Cancer diversity, even with similar morphology, impacts clinical outcomes.

Purpose of the Study:

  • To review advances in cancer gene expression profiling using DNA microarray technology.
  • To emphasize the application of these techniques in human prostate cancer research.
  • To discuss the implications of molecular profiling for cancer diagnosis and prognosis.

Main Methods:

  • Review of recent studies utilizing DNA microarray technology in cancer research.
  • Focus on gene expression profiling of human prostate cancer specimens.
