With the rapid advances in tumor genetics, an increasing number of amplifications have been identified in various human neoplasms (4). Examples of oncogenes amplified in tumors include N-myc and HER-2/neu, which have been proposed as prognostic markers in neuroblastoma and breast cancer, respectively (5,7). To date, most of the information on the amplification of genes has been gathered from co...
