Abstract The authors retrospectively analyzed epidermal growth factor receptor (EGFR) gene amplification in 49 cases of squamous cell carcinoma (SCC) arising from the nasal cavities (NC) and paranasal sinuses (PS) by using slot‐blot analysis of DNA extracted from formalin‐fixed, paraffin‐embedded tissues. Also, the relationship between the results of gene analysis and the clinical features of the patients was studied to investigate the clinical significance of the EGFR in SCC of the NC and PS. Amplification of the EGFR gene was detected in 5 of the 49 cases (10%). No significant difference was observed between EGFR gene amplification and the presence of lymph node metastases, local recurrence, or prognosis. This suggests that EGFR gene amplification is not related to the local progression or metastasis of the SCC in the NC and PS. In addition, it appears that amplification of the EGFR gene is not a prognostic indicator for SCC in the NC and PS.
