Résumé

The local control rate of chondrosarcomas treated with carbon-ion radiotherapy (CIRT) worsens as tumour size increases, possibly because of the intra-tumoural linear energy transfer (LET) distribution. This study aimed to evaluate the relationship between local recurrence and intra-tumoural LET distribution in chondrosarcomas treated with CIRT. Thirty patients treated with CIRT for grade 2 chondrosarcoma were included. Dose-averaged LET (LET The mean LET LET

BACKGROUND/AIM OBJECTIVE
The local control rate of chondrosarcomas treated with carbon-ion radiotherapy (CIRT) worsens as tumour size increases, possibly because of the intra-tumoural linear energy transfer (LET) distribution. This study aimed to evaluate the relationship between local recurrence and intra-tumoural LET distribution in chondrosarcomas treated with CIRT.
PATIENTS AND METHODS METHODS
Thirty patients treated with CIRT for grade 2 chondrosarcoma were included. Dose-averaged LET (LET
