Background:
To evaluate the role of postoperative treatment in parotid gland carcinoma (PGC) based on risk stratification.
Material And Methods:
A total of 301 PGC patients were retrospectively analyzed using risk stratification. The Kaplan-Meier method and Cox analysis were performed to conduct survival analysis.
Results:
In the high-risk group, those treated with postoperative radiotherapy (RT) had a better 5-year disease-free survival (DFS) than those treated with surgery alone. In the low-risk group, both surgery + RT and surgery + chemotherapy (CT) significantly improved DFS when compared with surgery alone. Cox analysis showed that patients who underwent surgery + RT or surgery + CT had a lower risk of disease progression than those who underwent surgery alone in the low-risk group. In the high-risk group, patients who underwent surgery + RT had a lower risk of disease progression.
Conclusions:
Postoperative RT showed considerable benefit in improving disease control in patients with PGC, even in those without high-risk factors.
