Abstract
BACKGROUND: The 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. METHODS: We reviewed the records of 61 consecutive patients with ACC. Surgery was performed in all patients. RESULTS: The 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). CONCLUSION: Careful 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.
