Abstract
BACKGROUND: The purpose of this study was to present our preliminary exploration of safety and efficacy of postoperative low-dose-rate brachytherapy for the early clinical stages of minor salivary gland carcinomas of the lip and buccal mucosa. METHODS: Twenty-seven patients with the early stages of minor salivary gland carcinomas of the lip and buccal mucosa received postoperative 125 I seed interstitial brachytherapy from March 2005 to May 2015. Actuarial likelihood estimates for local control, overall survival, and disease-free survival were calculated by Kaplan-Meier method. RESULTS: The actuarial 3-year, 5-year, and 10-year local control rates were 94.7%, 82.9%, and 82.9%, respectively. The actuarial 3-year, 5-year, and 10-year overall survival rates were 93.3%, 93.3%, and 77.8%, respectively. No patient experienced toxicity above grade 2. CONCLUSION: Postoperative 125 I seed interstitial brachytherapy is an alternative to radical surgery for early stages of minor salivary gland carcinomas of the lip and buccal mucosa, which offers satisfactory cosmetic and functional outcomes.
