This was resected over 2 years ago with reconstruction of the IVC with a PTFE graft. No preop or postop RT given and the recurrence is in the area where there was a positive margin. Patient has a good performance status and is not a candidate for chemo with Hx of AML s/p BMT 20 years ago and didn't tolerate postop chemo. If you recommend radiation what is the dose and fractionation?
