Brief Summary

Patients with malignant tumours of the cephalic pole have a poor prognosis, despite a wide range of treatments. prognosis despite a large therapeutic arsenal. Among this arsenal, radiotherapy (RT) is one of the standard treatments for these tumours. However, this treatment can cause damage to the surrounding healthy tissue, has limited efficacy in hypoxic However, this treatment can cause damage to the surrounding healthy tissue, has limited efficacy in hypoxic tissue and can promote pro-tumour inflammation. In these circumstances, hadrontherapy, which uses charged heavy particles, such as protons or carbon ions, is the preferred treatment. protons or carbon ions, seems more appropriate for the treatment of these tumours. However, although inflammation plays a major role in tumour development and tumour development and therapeutic response, few studies have evaluated the immune response response after proton therapy (PT) and carbon therapy (CT). The objective of this project is to study the effect of hadrontherapy on resident/circulating inflammation after brain irradiation. brain irradiation. In a first step, the impact of different PT and CT TEL on macrophages (M\Ф), the most abundant immune cells in malignant solid tumours, will be evaluated in vitro. malignant solid tumours, will be evaluated in vitro. In a second step, the evolution of circulating leukocytes after brain irradiation with X-rays or protons will be studied in vivo in rodents and patients. rodent and patient. In this project, we propose to study for the first time the inflammatory response after hadrontherapy in the context of a cephalic tumour. cephalic tumour. These results will allow a better understanding of the biological response response following PT and CT with the aim of optimising RT and potentially and potentially translate these data to the clinic.
