Background and PurposeAdenoid cystic carcinoma (ACC) is characterized by high rate of local recurrence and late distant metastasis. The status of an elective neck dissection (END) is controversial discussed in the literature.MethodsIn this study we analyzed the surgical treatment and follow up examinations of 59 patients with adenoid cystic carcinomas of a salivary gland treated in a single center between 1980 and 2016 retrospectively.ResultsThe incidence of occult nodal metastases among all patients who underwent elective neck dissection was 20.6%. The overall survival and the disease free survival of patients who underwent END vs. patients without END showed no significant differences. Even in case of positive lymph nodes metastasis there was no significant benefit in the survival or the local recurrence control.ConclusionThe incidence of occult neck metastases in patients with ACC was 20.6%. There was no significant enhanced survival shown in the group of patients who underwent an END.
