ABSTRACT

<p><b>OBJECTIVE</b>To study the clinical characteristics, treatment and prognosis 24 cases of carcinoma in pleomorphic adenoma in salivary gland.</p><p><b>METHODS</b>The clinical data of 24 patients with carcinoma in pleomorphic adenoma treated in our hospital from September 1974 to July 1995 were analyzed.</p><p><b>RESULTS</b>The overall 5-year survival rate was 66.7%. The five-year survival rates of patients with carcinoma in pleomorphic adenoma in the major and minor salivary glands were 63.6% and 2/2, respectively.</p><p><b>CONCLUSION</b>Operation is the optimal treatment and extensive resection at the initial operation is suggested. For lumps in the submaxillary gland, preventive neck dissection should be considered. Postoperative radiotherapy can not improve the local-control rate.</p>
