*2.2.5 Parotid gland*

The primary treatment for the cancer of parotid gland is surgical resection. Radiotherapy is used for adjuvant postoperative treatment except in small and low histological risk tumor with clear surgical margins [26]. In addition, radiotherapy is also indicated as radical treatment in advanced parotid gland cancer cases when resection of the tumor is not possible [27]. The prescribed dose to the primary site is about 66 Gy. IMRT is advocated as the treatment technique to improve OARs sparing [28].
