Abstract
The clinical data of 61 patients of salivary duct carcinoma admitted to the First Medical Centre of Chinese PLA General Hospital from January 2010 to December 2020 were retrospectively reviewed. A total of 55 patients (90.2%) were male and 6 (9.8%) were female. There were 51 patients (83.6%) aged≥50 years. The primary tumor of 45 patients (73.8%) were from the parotid gland. There were 35 patients (57.4%) who had cervical lymph node metastasis and 25 patients (41.0%) had distant metastasis. All patients underwent surgery and 50 of them (82.0%) received adjuvant radiotherapy. The 3-year and 5-year survival rates were 58.0% and 43.3%, respectively. Compared with the patients who had undergone surgery only, the survival rates of those who had postoperative adjuvant radiotherapy and chemoradiotherapy were higher. It can be seen that radical surgical treatment is necessary, and postoperative radiotherapy can reduce the recurrence rate and increase the survival rate to a certain extent.
