Total Body Irradiation and Total Skin Irradiation Techniques in Belgium and the Netherlands: Current Clinical Practice.

PURPOSE: In 2014, a Belgian/Dutch Nederlandse Commissie voor Stralingsdosimetrie (NCS) task group was formed to develop guidelines on the clinical practice of total body irradiation (TBI) and total skin irradiation (TSI). METHODS AND MATERIALS: As a basis for these guidelines, a survey conducted among 17 Belgian and Dutch radiation oncology institutions measured the clinical practice of TBI. Four of these institutions also performed TSI. An update was performed in 2019 and 2020 because several institutions innovated their TBI techniques. RESULTS: As old and more recent studies have shown, clinical protocols for TBI and TSI still vary considerably between institutions. CONCLUSIONS: New radiation therapy technologies have been introduced relatively slowly for TBI purposes.
