[Regarding assessment of changes in the larynx after radiation according to RTOG/EORTC classification]

The authors discuss the classification of changes in reactions occurring during and after radiotherapy of the laryngeal cancer adopted in 1987 by Radiation Therapy Oncology Group and European Organisation for Research and Treatment of Cancer (RTOG/EORTC). The above classification is not based on uniform criteria. The authors express the opinion that is extremely difficult to distinguish between chondritis, chondronecrosis of high intensity and necrosis without microscopic examination and limiting oneselves to the subjective symptoms only. In they opinion the classification of the post-radiation reaction should take into account the clinical assessment of the state of the larynx as well as the subjective elements of the examination. The authors have their findings on their own clinical and microscopic research as well as on the date accessible in the relevant literature.
