Background and Objective: Salivary duct carcinomas are an uncommon but distinct group of highly malignant salivary gland tumors. It is the purpose of this article to analyse the clinical courses and the results of treatment for salivary duct carcinoma. Materials and Method: The study was conducted a retrospective review of 10 consecutive patients’ records seen over a 12-year period from 1989 through 2000 at Department of Otolaryngology-Head and Neck Surgery, Korea Cancer Center Hospital. Results: Tumors originated from parotid gland in 7 patients and from submandibular gland in 3 patients. In parotid tumor, locoregional recurrence was developed in 4 patients and distant metastasis was found in 3 patients. In submandibular tumor, locoregional recurrence was developed in 2 patients, and distant metastasis was in all 3 patients. Conclusion: We point out the highly aggressive biological behavior of the tumor and poor prognosis. We hope this report will be help for further research. (J Clinical Otolaryngol 2001;12:249-253)
