The upper aerodigestive tract mucosa of patients who develop squamous cell carcinoma of the head and neck (SCCHN) is predisposed to abnormally regulated growth, evidenced by the high incidence of synchronous and metachronous malignancies. We conducted a series of experiments to show that aberrant re

Abstract
Epidermal growth factor receptor (EGFR), a receptor tyrosine kinase that activates multiple signaling pathways, including phosphatidylinositolβ3βkinase/vβAKT murine thymoma viral oncogene homolog protein (Akt), has long been a target of novel therapies. Despite universal EGFR expression in head and neck squamous cell carcinoma (HNSCC), the majority of patients do not respond to EGFR inhibitors. This review focuses on mechanisms of resistance to these agents in HNSCC, and how these may be unique when compared with other malignancies such as nonβsmall cell lung and colorectal cancers. Published studies and abstracts reveal that there are likely several mechanisms underlying resistance, suggesting that different strategies will be required to improve efficacy of EGFR inhibitors in HNSCC.

## Abstract ## Background This study was to explore whether the efficacy of the epidermal growth factor receptor (EGFR) tyrosine kinase inhibitor ZD1839 (Z, Iressa, gefitinib) plus chemotherapeutic agents docetaxel (D) and cisplatin (P) may benefit from sequencing of the combination. ## Methods
## Abstract Although disease management of head and neck squamous cell carcinomas (HNSCC) has improved significantly, therapy resistance leading to tumor recurrence still counteracts improvement of longβterm survival. Consequently, identification of molecular markers that signal increased risk of t
Chemotherapy for advanced ovarian cancer remains suboptimal. Despite the improvements in objective response rates realized with cisplatin-based combination chemotherapeutic regimens, most patients still die of refractory cancer.
