Carbon ion radiotherapy, with its powerful biological effects, provides excellent therapeutic efficacy for patients with radioresistant tumors. By focusing the irradiation beam on the target lesion, this approach guarantees a low probability of damage to critical organs (e.g., the brain, spinal cord, eyes and optic nerves) in the immediate vicinity of the target tumor. With regard to tumors in the head and neck region, carbon ion radiotherapy is indicated for the treatment of adenoid cystic carcinomas, adenocarcinomas and malignant mucosal melanomas in the oral and maxillofacial area. The safety and efficacy of this therapy have been established. Certain groups of radioresistant tumors are not indicated for surgical resection because of possible surgery-induced injury to critical organs, and these tumors raise a significant clinical concern because of the paucity of effective treatment options. Carbon ion radiotherapy represents a definitive treatment for these malignancies.},
