The authors regret that there is an error in their original article. They found a small mistake in the abbreviations, because the meaning of ESTRO and EORTC has been interchanged. It says:

-EORTC = European Society for Radiotherapy and Oncology

-ESTRO = European Organisation for Research and Treatment of Cancer

But it should be:

-ESTRO = European Society for Radiotherapy and Oncology

-EORTC = European Organisation for Research and Treatment of Cancer
