Texte intégralThe development of innovative methods capable of reducing the sensitivity of healthy tissue to radiation, while maintaining the effectiveness of the treatment on the tumour, is a central aspect of improving the effectiveness of radiotherapy in the treatment of cancer. Among possible developments and methodological innovations, the combination of ultra-high dose rate irradiation (FLASH) and very high energy electrons (VHEE) could make it possible to exploit the radiobiological advantages of the FLASH effect for the treatment of deep tumours. In particular, VHEEs in the 100 to 250 MeV energy range would be particularly interesting from a ballistic and biological point of view for the application of FLASH irradiation in radiotherapy. This thesis therefore studies the possible use of VHEEs in radiotherapy, and in particular their use at ultra-high dose rates, thus assessing the feasibility of FLASH-VHEE radiotherapy. Although promising, several aspects of this technique need to be studied before it can be used in a clinical context. The first part of this work studies the machine parameters required to meet the constraints of FLASH irradiation. To this end, an analytical model for calculating the dose based on Fermi-Eyges multiple scattering theory was developed and tested. This analytical model has also been used to design and optimise a double-scattering system for VHEE therapy, in order to obtain field sizes greater than 15x15 cm², and to assess the possible adaptation of conventional particle beam conformation methods for FLASH-VHEE therapy. The second part of this work focuses on VHEE treatment planning and the evaluation of clinical plans. Four representative clinical cases were studied, for which pencil-beam scanning (PBS) and double scattering (DS) treatment plans were calculated. The influence of beam energy on plan quality was studied and the PBS and DS techniques were compared. A temporal description of the irradiation was also carried out, as well as the incorporation of a FLASH modification factor when evaluating the plan and its effect on healthy tissue in FLASH mode. Finally, the estimation of doses from secondary particles and radiation protection issues were addressed. A calculation of the secondary dose due to Bremsstrahlung photons and neutrons from the two dose delivery systems was developed in water. The secondary particle dose received by various organs was also assessed in the context of intracranial treatments and in order to demonstrate the advantage of VHEE beams over proton beams in terms of out-of-field neutron dose. In summary, the fast analytical models parameterised in this study allow the dose distribution produced by a VHEE system to be estimated with good accuracy, providing important information for the potential design of a VHEE system. The results of this work could support the development of FLASH-VHEE radiotherapy

Texte intégralEn stor andel cancerpatienter får strålterapi som läkande eller palliativ behandling. Strålterapi kan ge upphov till allvarliga skador i den friska vävnaden i närheten av tumörområdet. För att förebygga omedelbara så väl som långsiktiga skadliga effekter av strålterapi, har nyligen pulicerade studier undersökt en ny teknik som kallas för FLASH strålterapi. Man har påvisat att ultra-höga doshastigheter kan minska strålskadorna i friska celler samtidigt som tumörkontrollen bevaras. Emellertid finns ännu ingen tillräcklig förklaring för den exakta mekanismen bakom fenomenet. Målet med detta projekt är att undersöka om en ökning eller minskning av koncentrationen hos radikalen hydroxyl, som är känd för att spela en kritisk roll i framkallandet av DNA skador, kunde upptäckas för särskilda doseringsmönster med en oförändrad total dos. Detta studerades med en enkel matematisk modell (RadChemModel) för vatten med upplöst syre. Med denna modell simulerades de kemiska reaktioner som äger rum när vatten bestrålas med joniserande strålning. Från fundamentala kemiska reaktionslagar, kunde koncentrationen av hydroxyl som funktion av tid fås genom att lösa ett system av linjära och icke-linjära ordinära differentialekvationer. Den här modellen visar att det kan finnas en skillnad i strålinducerade skador mellan FLASH och vanlig strålterapi. Resultaten från väldigt höga pulsfrekvenser med FLASH antydde också att mindre hydroxyl producerades och därmed att strålskador kan vara beroende av både doshastighet och pulsfrekvens. Däremot är resultaten inte tillräckliga för bekräfta att koncentrationen av hydroxyl är reducerad för FLASH.
