Heavy Ion Radiotherapy

To observe the efficacy and toxicities of heavy ion radiation therapy for locally advanced or advanced primary thymic epithelial malignant tumor received R2 resection. The primary endpoint was progression-free survival and toxicities, and the secondary endpoint was local relapse-free survival, overall survival and cause-specific survival.

The objective is to use the advantages of heavy ion physical dosimetry and biology to improve the tumor control rate and long-term survival rate of high-grade glioma, reduce the occurrence of brain tissue radiation damage caused by increasing prescription dose, and provide new treatment suggestions for glioma radiotherapy.
