A much-needed collection of cutting-edge methods for the detection and discovery of new cancer markers, particularly molecular tumor markers. Each method is fully described by a hands-on expert who regularly uses it in the laboratory and has perfected it to a high degree of ready reproducibility. Special emphasis is given to statistical considerations in the analysis of tumor markers, recent discoveries in the field of serum and tissue marker proteins, cytogenetic markers, molecular markers, and markers for the early detection of cancer. The well-honed procedures detailed here will enable cancer researchers and clinical oncologists alike to realize the promise of these powerful new diagnostic strategies for the detection, therapy, and successful prevention of cancer.
