    Author: Yu GY, Ma DQ.
    Journal: Zhonghua Zhong Liu Za Zhi; 1986 Sep; 8(5):395-8. PubMed ID: 3032547.
    Abstract:
    342 cases with carcinoma of salivary glands were analysed. 152 tumors were located in parotid, 42 in submaxillary, 17 in sublingual and 131 in minor salivary glands. Pathological diagnosis were 106 mucoepidermoid carcinoma, 80 adenoid cystic carcinoma, 54 malignant mixed tumor, 40 adenocarcinoma, 38 papillary cystadenocarcinoma, 17 acinic cell carcinoma, 5 squamous cell carcinoma, and 2 undifferentiated carcinoma. The 3, 5, 10 and 15 year survival rates of these 342 cases were 76.6%, 65.9%, 48% and 29%, respectively. The difference between survival rate and relapse-free survival rate was about 8%. The prognosis of acinic cell carcinoma and mucoepidermoid carcinoma was much better than that of squamous cell carcinoma, adenocarcinoma and undifferentiated carcinoma. The survival rates, according to location, were: minor salivary gland tumors the highest, and those of submaxillary gland tumors the lowest. Postoperative radiotherapy improved the survival rate of adenoid cystic carcinoma. The overall recurrence rate was 37.4%, the neck lymph node metastasis rate 14.3% and the distant metastasis rate 9.1%.
