Tumor marker analysis constitutes a sizable portion of routine clinical chemistry testing. This area of investigation has advanced considerably over the last 50 years. Many new tumor markers have been discovered and are now used routinely for cancer screening, diagnosis, and monitoring and for prediction of therapeutic response. Despite these advances, it is clear that the contribution of these markers to patient care and, especially, to altering clinical outcomes is relatively limited. Most, if not all, of the markers that we use today are compromised by their low diagnostic sensitivity and specificity. The nature of cancer as a disease is such that it is not acceptable to misdiagnose or mistreat patients. For this reason, tumor markers are not used for definitive diagnosis; they are used as aids to help physicians make decisions, after combining other clinical and diagnostic data.
