title: [Clinical analysis of 202 cases of malignant tumor of the major salivary glands].
abstract: From March 1963 to July 1982, 202 patients with malignant tumor of the major salivary glands were admitted to our hospital. 198 cases were treated by surgery alone or combined with postoperative radiotherapy. The overall 3, 5, 10, 15-year survival rates were 73.2%, 59.6%, 41.5% and 29.9% respectively. The 5-year survival rates of parotid tumor, submandibular gland tumor and sublingual gland tumor were 65.2%, 44.2% and 60% respectively. The prognosis of the patients with a poor-differentiated pathology, especially the 10-year survival rates, were poor. In this study 50 cases were treated with postoperative radiotherapy. 118 cases without radiotherapy. The 5-year survival rates of the both were 62.5%, 57.0% respectively. After operation, 44 cases had positive evidence of microscopic metastasis. Of them, there were 21 cases had postoperative radiotherapy, 23 cases had not.
