## Abstract MicroRNAs (mirs) are small noncoding RNA molecules (βΌ22 nucleotides) that regulate posttranscriptional gene expression. Currently, there has not been a comprehensive study of their role in primary head and neck squamous cell carcinoma (HNSCC). To determine the role of mirs in HNSCC, we

Abstract
Background
The aim of this review was to discuss the role of altered fractionation and adjuvant chemotherapy for patients treated with definitive radiotherapy (RT) for head and neck squamous cell carcinoma (HNSCC).
Methods
This review explores the pertinent literature and discusses the optimal management of previously untreated patients with stage IIIβstage IVA and/or βB HNSCCs.
Results
Depending on the schedule, altered fractionation improves locoregional control and survival. Both hyperfractionation and concomitant boost RT improve locoregional control and are associated with improved overall survival (OS). Adjuvant chemotherapy improves OS; the greatest impact is observed after concomitant versus induction or maintenance chemotherapy. Monochemotherapy appears to be equivalent to polychemotherapy. Drugs associated with the greatest survival benefit include fluorouracil and cisplatin. Intraarterial chemotherapy offers no advantage over intravenous chemotherapy. Concomitant cetuximab and RT results in improved outcomes similar to those observed after concomitant cisplatinβbased chemotherapy and RT.
Conclusions
Altered fractionation and/or concomitant chemotherapy result in improved outcomes compared with conventionally fractionated definitive RT alone for stage IIIβstage IV HNSCC. The optimal combination of RT fractionation and chemotherapy remains unclear. Β© 2009 Wiley Periodicals, Inc. Head Neck, 2009

## Abstract Comparative genomic hybridization (CGH) was used to detect chromosomal changes during metastasis formation of head and neck squamous cell carcinomas (HNSCCs). In total, 92 tumors of 54 patients were investigated. In 34 of these, the metastases were compared to the corresponding primary
Molecular studies have revealed that microsatellite instability and loss of heterozygosity occurred in head-and-neck cancer, suggesting the involvement both of suppressor and of mutator pathways in head-and-neck carcinogenesis. There is evidence for relations between tumor phenotype and clinical par

The emerging field of proteomics offers great promise for unraveling the complex molecular events of tumorigenesis, as well as those that control clinically important tumor behaviors such as metastases, invasion, and resistance to therapy. Understanding the molecular basis of these tumor characteris
