				        	Objective To evaluate the risk of locoregional recurrence (LRR) and the influencing factors for long-term survival in patients with epithelial-myoepithelial carcinoma (EMCa).Methods A retrospective analysis was performed for 18 EMCa patients, who received initial therapy or initial adjuvant therapy in our hospital from 1999 to 2015, to investigate their survival.Among these patients, 8(44%) underwent surgery alone, 9(50%) received adjuvant radiotherapy, and 1(6%) received radical concurrent chemoradiotherapy.Locoregional recurrence-free survival (LRFS) and overall survival (OS) rates were compared between these groups.The Kaplan-Meier mtthod was used to calculated survival rates and log-rank test was used to compare the LRFS.Results With a median follow-up time of 46 months, 5 patients developed LRR, and the 5-year LRFS and OS rates were 69% and 93%, respectively.The patients treated with radiotherapy had a significantly higher 5-year LRRFS rate than those not treated with radiotherapy (71% vs.57%, P=0.569).Conclusions LRR is the main failure mode of EMCa treatment, and further improving local control is the key to improved survival.
