The polymerase chain reaction (PCR) has had a significant impact on all aspects of the molecular biosciences, from cancer research to forensic science. The sensitivity and specificity inherent in the technique allow minute quantities of genetic material to be detected while the unique properties of thermostable DNA polymerase ensure that abundant copies are reliably reproduced to levels that can be visualized and/or used for further applications. This chapter describes applications of PCR and PCR-RT to investigate primary cancer and metastatic disease at both the DNA and mRNA expression levels.
