Surface-enhanced laser-desorption and ionization time-of-flight mass spectrometry (SELDI-TOF MS) shows promise for early cancer detection by identifying novel biomarkers. Further research is needed to ensure reproducibility and standardization for clinical use.

Area of Science:

  • Biomarker Discovery
  • Proteomics
  • Mass Spectrometry

Background:

  • Proteomic approaches are increasingly utilized for disease diagnosis.
  • Surface-enhanced laser-desorption and ionization time-of-flight mass spectrometry (SELDI-TOF MS) is a promising proteomic technology.

Purpose of the Study:

  • To review literature on proteomic technologies for early cancer detection.
  • To evaluate the potential of SELDI-TOF MS in cancer diagnostics.

Main Methods:

  • Literature review of English language studies.
  • Utilized PubMed and Medline databases.
  • Focused on studies employing proteomic technologies for cancer detection.

Main Results:

  • SELDI-TOF MS is an array-based mass spectrometry technique.
