What is the role of local control +/- whole lung irradiation in a patient with relapsed/refractory Ewing sarcoma to the hilum plus multiple lung nodules?

I would boost residual thoracic disease to at least the usual Ewings gross disease dose of 55.8 (total, including WLI dose). Doses in this range are well known to be safe in the thorax and this multiply relapsed disease is likely to be more treatment refractory than primary disease. SBRT boost seems...

I would do whole lung and boost to hilar nodes, given prior history.
