Abstract
OBJECTIVE: Adenoid cystic carcinoma (ACC) is characterized by a high rate of local recurrence and late distant metastasis. The status of an elective neck dissection (END) is controversial in the literature.
STUDY DESIGN: In this study we retrospectively analyzed the surgical treatment and follow-up examinations of 59 patients with ACCs of a salivary gland treated in a single center between 1980 and 2016.
RESULTS: The incidence of occult nodal metastases among all patients who underwent END was 20.6%. The overall survival and the disease-free survival of patients who underwent END versus patients without END had no significant differences. Even in the case of positive lymph nodes metastasis there was no significant benefit in survival or local recurrence control.
CONCLUSION: The incidence of occult neck metastases in patients with ACC was 20.6%. There was no significant enhanced survival in the group of patients who underwent an END.
