Heavy ion therapy for skull base tumors
The main types of skull base tumors include chordoma, chondrosarcoma, pituitary tumor, craniopharyngioma, skull base meningioma, olfactory neuroblastoma, etc. These tumors are difficult to completely remove due to their proximity to the organs at risk. Traditional photon radiotherapy is limited by normal tissue damage and other factors, so heavy ion radiotherapy has become a promising treatment.
The existing case data of NIRS in Japan for heavy ion treatment of skull base show that the 5-year local control rate of heavy ion radiotherapy for skull base chordoma, chondrosarcoma, pituitary tumor, craniopharyngioma, skull base meningioma, olfactory neuroblastoma, etc., is more than 80%, the 5-year overall survival rate is more than 50%, and the toxic side effects are very mild or no.
The clinical symptoms of skull base tumor vary according to the location and scope of the tumor. In front skull base tumor, there may be anosmia, nasal obstruction, headache, etc., in middle skull base tumor, there may be diplopia, eyelid ptosis, visual field defect, eye protrusion, etc., and in back skull base tumor, tinnitus, vertigo, impaired hearing, etc. In carbon ion therapy, it is important to determine the distance between the tumor and the organs at risk, including the brain stem, spinal cord, and cranial nerves, because it is difficult to protect nerve function when the tumor is close to the organs at risk.

Indications for the treatment of skull base tumors with heavy ions
1. Skull base tumor with definite diagnosis;
2. Skull base tumors with larger resection scope or more postoperative complications that are unwilling to receive surgical treatment;
3.postoperative residual need for radiotherapy;
4. Patients who relapse after surgery and cannot be operated again;
5. the lesion around the blood vessels or nerves, surgery can not be removed.
