[en] Purpose: Salivary gland tumors are relatively rare malignancies that are not commonly seen in the usual radiation oncology practice. The purpose of this course is to review the role of radiotherapy in the treatment of salivary gland tumors and to provide specific examples of treatment planning techniques for selected cases. Materials and Methods: Salivary gland tumors comprise a diverse group of histologies often with unique patterns of spread. An overview of the implications of this as it impacts treatment decisions will be presented. Both malignant neoplasms and 'benign' pleomorphic adenomas will be discussed. The historical data relating to the role of radiotherapy in the treatment of salivary glands is reviewed. Currently the mainstay of treatment is surgery and the rationale and specific indications for postoperative radiotherapy discussed. A comparison is made between conventional low linear energy transfer (LET) photo/electron irradiation and high LET neutron radiation and specific indications for the later form of treatment delineated. The limited data on interstitial implants, hyperthermia, and altered fractionation treatment regimens will also be mentioned. Examples of treatment planning approaches used in specific cases will be presented. These examples will be selected in order to illustrate alternative approaches to the more familiar 'parallel opposed' techniques. Results: Hopefully at the end of this course the attendees will have a greater appreciation of the role of radiotherapy in the treatment of salivary gland tumors and will be able to apply this information to such tumors as will be seen in their practices. Conclusions: Radiotherapy has much to offer in the treatment of salivary gland tumors both from the viewpoint of improving cosmesis and function by allowing less radical surgery to be performed
