Mass spectrometry MALDI imaging of colon cancer biomarkers: a new diagnostic paradigm.
Colorectal cancer (CRC), is the second-leading cause of cancer-related deaths in the USA, affecting both men and women. Current projections show little or no change since the publication of a morbidity and mortality study in 2005. The projected number of new cases for 2008 is 154,000, and the projected number of CRC cancer deaths for 2008 is 53,000. The standard diagnostic paradigm is based on histopathology of either biopsy or surgical specimens. This article suggests a new paradigm for colon cancer diagnosis and staging using matrix-assisted laser desorption/ionization imaging mass spectrometry (MALDI IMS or IMS). IMS may identify potential tumors in normal tissue of cancer patients and predict those cancer patients who are at risk for recurrent cancer.
