Background: Identification of molecular events of the recurrent squamous cell carcinoma (SCC) of the larynx and pharynx may aid in refining treatment strategies and improving outcome. The underlying molecular events of these recurrent tumors involve alterations in the tumor suppressor genes (p53) and protooncogenes (Bcl-2). We hypothesize that the development of these recurrent tumors involves alterations of the p53 and ...
