Brief Summary:
Thanks to the intrinsic qualities of the proton beam, proton therapy will reduce adverse effects of irradiation. The Proteus®One is the latest generation of proton therapy equipment, enabling the Centre Antoine Lacassagne to expand its range of treatments by carrying out new proton therapy treatments. It has an innovative compact isocentric rotating head (Gantry) that allows the radiation beam to be directed at different angles around the patient. In some cases, two beams are used to treat tumours, and by convention, both beams are delivered during the same session. However, it is necessary to position the patient before each beam, which is time-consuming because 2 beams have to be positioned very precisely each day. The aim of this study is therefore to assess the toxicity of proton therapy delivered by a single daily beam compared with proton therapy delivered by two daily beams, which is the conventional technique.

Estimated Enrollment : 106 participants
Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: None (Open Label)
Primary Purpose: Treatment
Official Title: Analysis of the Toxicity and Efficacy of Daily 1 vs 2 Beam Proton Therapy : Analysis of the Toxicity and Efficacy of Daily 1 vs 2 Beam Proton Therapy
Actual Study Start Date : September 13, 2023
Estimated Primary Completion Date : September 1, 2026
Estimated Study Completion Date : October 1, 2031


Arm Intervention/treatment
Experimental: 1DB
One daily Beam treatment
Radiation: Proteus ONE one daily beam
A single daily beam is used, doubling the dose delivered for this treatment incidence.

Active Comparator: 2DB
Two daily beam goldstandard
Radiation: Proteus ONE two daily beam
two daily beams are used, in accordance with the initial treatment plan and the patient's standard of care




Primary Outcome Measures :
  1. To evaluate the frequency of occurrence of toxicities in the group of patients treated with two daily beams (2DB) and in the group of patients treated with one daily beams (1DB). [ Time Frame: During 2 to 7 weeks of protontherapy treatment and during 5 years follow-up ]
    Assessment of the incidence of grade ≥2 medical device-related toxicities assessed according to CTCAE version 5.0 in each of the two treatment arms.


Secondary Outcome Measures :
  1. Determining the effectiveness of proton therapy [ Time Frame: 5-year follow-up visits ]
    Efficacy will be assessed in terms of relapse rate

  2. Determining the effectiveness of proton therapy [ Time Frame: 5-year follow-up visits ]
    Efficacy will be assessed in terms of local control by MRI assessment

  3. Determining the effectiveness of proton therapy [ Time Frame: 5 years follow-up ]
    Efficacy will be assessed in terms of overall survival

  4. Quality of life assessment [ Time Frame: During 2-7 weeks of protontherapy treatment and during 5 years follow-up ]
    Quality of life will be assessed using the EORTC QLQ-C30 scale (Appendix 2), version 3 at the inclusion assessment, at the end-of-treatment visit and at each assessment visit for five years. Version 3.0 of the QLQ-C30 has four-point scales for the items 1 to 28 namely : 1 : "Not a tall", 2 : "A little", 3 : "Quite a bit" and 4 : "Very much." Higher score mean worse outcome. Item 29 and 30 has seven-point scales from 1 : " very bad " to 7 "Excellent". Lower score mean worse outcome.

  5. Evaluate the time saving between the two arms 1DB and 2DB [ Time Frame: 2-7 weeks of protontherapy treatment ]
    Time savings will be assessed by measuring the time taken for door-to-door proton therapy treatment sessions.
