[Prognostic molecular markers in oral and lip squamous cell carcinoma--evaluation of expression and its significance].

Introduction: Head and neck cancer treatment optimization and individualization has become possible due to the implementation of the prognostic and predictive molecular markers in diagnostics.

Aim: The aim of this study was an attempt to determine which of the investigated molecular markers may have prognostic and predictive value in head and neck cancers.

Materials And Methods: The paraffin blocks from 47 patients with oral and lip squamous cell carcinoma (SCC) after surgical treatment in the Institute of Oncology in Gliwice in the period of 1998-2002 were investigated.
