Postoperative radiation therapy for malignant tumors of minor salivary glands. Outcome and patterns of failure

Abstract

Postoperative radiation therapy is effective in preventing local recurrence in most patients with minor salivary gland tumors after gross total excision. When local failure occurs, it tends to be a late event. For most patients, the authors recommend a postoperative dose of 60 Gy in 30 fractions to the operative bed; if there is named nerve invasion, the path of the nerve is treated electively to its ganglion.
