Salivary neoplasms: overview of a 35-year experience with 2,807 patients.

We have reviewed a 35-year experience with 2,807 patients treated for salivary tumors which arose in the parotid gland (1,695 patients; 70%), submandibular gland (235 patients; 8%), and seromucinous glands of the upper aerodigestive tract (607 patients; 22%). Pleomorphic adenomas comprised 45% of the total, most of which occurred in the parotid gland. The clinical findings and the distribution of patients according to the histology and the site of origin are summarized. Treatment was surgical and the resection was conservative when possible, depending upon the extent of the tumor. The impact of site, histology, grade, and tumor stage on the results is shown.
