OBJECTIVE: @entity189 ( @entity189 ) is a rare @entity5 of the salivary gland. The aim of this study was to analyze the diagnosis, treatment and prognosis of @entity189 of the parotid gland. METHODS: The clinicopathological data of 17 cases of @entity189 of the parotid gland treated in our hospital from 1999 to 2013 were analyzed retrospectively. Of all the 17 @entity1 , 9 cases received radical surgery only, 5 cases received postoperative radiotherapy, 2 cases received preoperative radiotherapy, and one case received chemotherapy. The survival rate was calculated by Kaplan-Meier analysis. RESULTS: Among the 17 @entity1 , 11 @entity1 had post-operative recurrence (11/17, 64.7%), Of these 11 cases, 5 cases (45.5%) had recurrence within one year after the first operation. During the follow-up for 12-180 months (median 50 months), six cases died (two @entity1 died of distant metastases and 4 cases died of local recurrence). The overall 1-year, 2-year and 5-year survival rates were 94.1%, 74.2% and 64.9%, and the overall 1-year, 2-year and 5-year recurrence-free survival rates were 70.6%, 48.1% and 40.1%, respectively. CONCLUSIONS: Radical surgery is the main treatment modality for @entity189 of the parotid gland. For the @entity1 with extensive lesions or after palliative surgery, adjuvant radiotherapy or chemotherapy might be helpful. However, its therapeutic efficacy remains to be proved.
