Assessment of Salivary Function Change in Nasopharyngeal Carcinoma Treated by Parotid-Sparing Radiotherapy

Abstract

With parotid-sparing radiotherapy for nasopharyngeal carcinoma, gland function can recover significantly 12 months after radiotherapy. There were significant rank-order correlations between LENT/SOMA subjective and objective (analytic) grading scores at 6 to 18 months' follow-up.
