The overall prevalence of amplifications of five oncogenes analyzed was 34.5% for CCND1, 12.7% for EGFR, 8.8% for MYC, 6.2% for ZNF217, and 3.6% for ERBB2. CCND1 amplifications were associated with the pharyngeal site in primary carcinomas (P < 0.001), whereas amplifications of ZNF217 were less frequent in pharyngeal carcinomas as compared with primary oral and laryngeal carcinomas (P = 0.02). The amplification pattern of these oncogenes suggests that different molecular pathways are involved in HNSCCs of different localizations. ©2003 American Association for Cancer Research.
