Salivary Gland. Photon beam and particle radiotherapy: Present and future

Salivary gland cancers (SGCs) are uncommon diseases accounting for only 2 –6.5% of all head and neck cancers, and are characterized by considerable variability in their biology and natural history [1]. Mucoepidermoid carcinoma (MEC), adenoid cystic carcinoma (ACC), and adenocarcinoma are the most frequent diagnoses, representing > 75% of all SGCs, although their frequency varies according to the site of origin (major vs minor salivary glands) [2]. Prognosis among SGCs differs according to histology and grading: non-ACC and high-grade tumors are associated with a poorer prognosis compared with low-grade tumors [3 –5].
