Background: Proton therapy (PRT) is an innovative radiotherapeutic modality for the treatment of cancer with unique ballistic properties. The depth-dose distribution of a proton beam reduces exposure of healthy tissues to radiations, compared with photon-therapy (XRT). To date, only few indications for proton-therapy, like pediatric cancers, chordomas, or intra-ocular neoplasms, are reimbursed by Health systems.

Background: We conducted a systematic review to evaluate outcomes and toxicities associated with proton therapy in the treatment of adult-type diffuse glioma.

Methods: Following PRISMA guidelines, we searched PubMed for both prospective and retrospective studies on proton therapy for adult diffuse gliomas, including IDH-mutated gliomas WHO grade 2-3 and glioblastomas. Survival and toxicity outcomes were reported separately for these glioma types.

The management of these tumors is not clearly defined and radiotherapy indications should be discussed at a multidisciplinary board.

Chondrosarcoma is a malignant cartilaginous tumor that is particularly chemoresistant and radioresistant to X-rays. The first line of treatment is surgery, though this is almost impossible in some specific locations. Such resistances can be explained by the particular composition of the tumor, which develops within a dense cartilaginous matrix, producing a resistant area where the oxygen tension is very low.
