- Abstract
- BackgroundThe purposes of this study were to evaluate the oncologic outcomes of salivary gland adenoid cystic carcinoma (ACC) and to confirm the benefits of elective neck dissection. MethodsWe reviewed the records of 61 consecutive patients with ACC. Surgery was performed in all patients. ResultsThe occult metastasis rate was 15.38% (4 of 26 patients) and no regional recurrence in the elective neck dissection group was identified. Among 4 clinically node positive (cN+) patients, regional metastasis was identified in 3 through therapeutic neck dissection. Regional recurrence was identified in 4 patients (4 of 31) who had never undergone elective neck treatment of clinically node negative (cN-) status, exclusively. Overall regional metastases (overall N+) were identified in 11 patients. The overall survival rate was 84.99% at 5 years, 81.13% at 10 and 15 years in (overall N-) status, contrary to 56.82% at 5 years and 28.41% at 10 years in overall N+ status (p = .025). ConclusionCareful follow-up of regional status is important, and proper therapeutic and elective neck treatment can achieve regional control in ACC. Elective neck dissection is recommendable and can provide valuable staging and prognostic information. (c) 2014 Wiley Periodicals, Inc. Head Neck 36: 1796-1801, 2014
