Study of Biological Effect of Tarceva (OSI-774) for Patients Stricken by ENT Epidermoid Carcinoma
The purpose of this study is to evaluate the biological effect of Tarceva (OSI-774) from an inhibition of EGF tumor receptor tyrosine kinase activity's point of view, for patients who are carriers of head and neck epidermoid carcinoma.

|Official Title:||Pilot Study, Without Direct Individual Benefice, of Biological Effect of Tarceva (OSI-774) at Posology of 150 mg by Day for Patients Stricken by ENT Epidermoid Carcinoma Waiting for First Surgical Picking up.|
- To evaluate the biological effect of Tarceva (OSI-774) from an inhibition of EGF tumor receptor tyrosine kinase activity's point of view, for patients who are carriers of head and neck epidermoid carcinoma.
- Correlation study between pharmacokinetic and biological effect observed of molecule OSI-774.
- Verification of biological effect of Tarceva's homogeneity (inhibition of EGFR-TK) according to sites, particularly from the point of view of a possible difference primary tumor/metastatic adenopathy and tumorous tissue/healthy tissue.
- Characterisation of OSI-774 modes of action from the cellular cycle arrest proteinic effectors's point of view.
- Constitution of frozen tissue bank for genomic (sequencing) study of tumorous EGF-R structure and for modification of in situ gene expression induction with OSI-774 by RNA microarrays technology.
- Pharmacogenomics study of Tarceva's metabolism : genes studied code for cytochrome 3A5 and glycoprotein-P.
