Résumé : |
/Purpose : Protontherapy for mediastinal Hodgkin lymphoma reduces cardiac, lung and breast exposure, which may limit radiation-induced adverse events. While this technique is already widely implemented in the United-States, clinical experience is still limited in France. This study analyses the practice of mediastinal Hodgkin lymphoma protontherapy at the Institut Curie to implement this technique at a larger scale.
/Materials and Methods : Data from all mediastinal Hodgkin lymphoma patients from the hematology department of the Institut Curie who were subsequently evaluated at the Protontherapy Center of Orsay (CPO) of Institut Curie for adjuvant protontherapy were retrieved. We analyzed why these patients were ultimately treated with protontherapy or not. /Results : Between January 2018 and January 2021, twenty mediastinal Hodgkin lymphoma patients from the hematology department of the Institut Curie have been screened for protontherapy at the CPO. Four of them (20%) were ultimately treated with proton beams. Treatment was well tolerated without grade 3?4 adverse events. With a median follow-up of two years, none of these patients relapsed. The others sixteen patients were not treated with protontherapy due to multiple reasons including: lack of treatment room disponibility, accessibility difficulties, psychiatric disorder, and anatomic or dosimetric considerations. /Conclusion : Despite notable dosimetric superiority over photon radiotherapy and excellent clinical tolerance, lack of availability of protontherapy facilities limit implementation of mediastinal Hodgkin lymphoma protontherapy. Additionally, strict selection criteria must be defined. |
