What is the radiation volume for unresected gross paraaortic lymph node in a Wilms patient?   

Do you radiate the paraaortic chain to 10.8Gy then boost gross residual with 1cm block edge margin to 19.8Gy or simply treat the entire paraaortic chain to 19.8Gy w/o cone down?

Why is unresected gross node dose 19.8Gy but unresected gross disease dose 21.6Gy?
