How should patients be selected for metastatic-site directed radiotherapy in rhabdomyosarcoma?   

Should this be based off of the response? or the site of disease such as bone vs soft tissue?

What data are there to dictate that the prior (response, tissue type) should dictate RT indication (site selection), dose &/or volume?

Dose: 50.4 Gy (ARST 0431) or 40 Gy (ARST 1431)?

Volume: Pre- vs. post-chemo volume?

Timing: At the time of primary site treatment or end of therapy or interdigitated?

Should response guide RT indication or site selection?
