Abstract
Background.
The epidermal growth factor receptor (EGFR) and the inhibitor of apoptosis protein survivin play important roles in the regulation of cellular proliferation and survival in squamous cell carcinomas. Their correlation in oropharyngeal squamous cell carcinoma (OSCC) has not been evaluated yet.
Methods.
In this multicenter study, we analyzed the expression of survivin and EGFR in tissue specimens from 73 selected patients with OSCC using immunohistochemistry.
Results.
Higher cytoplasmic survivin scores were significantly correlated with high scores of EGFR expression (p = .013). Nuclear survivin expression was associated with a poor overall survival rate with an estimated 3βyear overall survival probability of 17.3% versus 87.4% for nonβnuclear expression of survivin (p <.001). Multivariate analysis revealed that nuclear survivin expression was an independent negative prognostic factor (p = .008).
Conclusion.
Considering the strong impact of nuclear survivin expression on survival, the survivin expression should be prospectively evaluated to select patients with an increased risk for disease recurrence. Β© 2008 Wiley Periodicals, Inc. Head Neck, 2008

Background: Evidence exists that estrogens influence the action of epidermal growth factor (EGFj and its receptor (EGF-Rj at multiple levels. Estrogen and antiestrogen action on gastric and other gastrointestinal malignancies has been evaluated by several groups with conflicting results, and EGF-R h
To evaluate the clinical significance of the expression of epidermal growth factor receptor (EGFr) in oral squamous cell carcinoma (SCC), 100 formalin-fixed, paraffin-embedded cases of this tumour and ten samples of normal oral mucosa were immunostained with a monoclonal anti-EGFr antibody using an
