[The clinical characteristic treatment strategy and prognosis of adenoid cystic carcinoma of the head and neck].

To explore the clinical characteristics, treatment strategy and prognosis of adenoid cystic carcinoma of the head and neck (ACCHN). A retrospective analysis of the clinical and follow-up treatment of 79 patients with ACCHN from June 2008 to July 2017 was conducted in the Cancer Hospital of Zhengzhou University. A total of 79 ACCHN cases, including 31 males and 48 females. The age ranged from 19 to 77 (median, 52). The clinical manifestations of ACC were related to the locations of primary tumor.The mean size of the tumor was 2.6 cm (range from 1.5 to 7.7 cm). 50 of 79 patients with a definitive pathological diagnosis received surgical resection. 59 cases received chemotherapy and 62 cases received radiotherapy. With a median follow-up of 55 months, the 5-year, 10-year survival rate of these patients were 69.6% and 54.4%, respectively. ACCHN is an uncommon neoplasm with the characteristics of epithelial nerve growth, being inclined to distant metastasis, and high early misdiagnosis rate. The clinical manifestation, imaging and pathological result are need to be combined together to diagnose ACCHN.
