Radiotherapy in the modern era in the management of langerhans cell histiocytosis

Radiotherapy has been shown to be effective in treating Langerhans cell histiocytosis (LCH) with no clearly defined role for conformal radiation techniques such as intensity-modulated radiotherapy. The goal of this study was to evaluate clinical outcomes and radiation dose to critical normal structures in patients treated for LCH with conventional and conformal radiotherapy techniques.
