[Prognostic factors in head and neck mucoepidermoid carcinoma].

Background: In patients with mucoepidermoid carcinoma (MEC) originating in salivary glands, because of the relative rarity of these tumors and the remarkable variability in their biological behavior, opinions differ about appropriate classification, grading, and treatment.

Objective: We undertook this study to analyze clinical and histological prognostic factors in a series of patients with MEC using univariate and multivariate survival analyses.

Methods: We reviewed 47 patients with MEC treated at our institution from 1985 to 2000.
