Association of tapasin and HLA class I antigen down-regulation in primary maxillary sinus squamous cell carcinoma lesions with reduced survival of patients.

Abstract

Tapasin expression appears to be associated with HLA class I antigen expression in primary maxillary sinus SCC lesions. Furthermore, defects in tapasin and HLA class I antigen expression in primary maxillary sinus SCC lesions may play a role in the clinical course of the disease, because these defects were associated with poor prognosis.
