Background: Salivary glands present a wide diversity in histopathologic types and biologic behaviors, thus complicating the search for prognostic factors.
Methods: We compared 2 prognostic scores that were previously published for patients with parotid carcinoma in a retrospective series of 175 patients treated in a single institution.
Results: Cox multivariate analysis indicated clinical skin invasion, facial nerve function, and perineural growth as the most significant recurrent disease-related prognostic factors.
