Would you offer adjuvant RT to a FIGO IV endometrial CA with pulm mets s/p hysterectomy with residual disease, then cCR to both sites after chemotherapy?

For stage IVB with extra pelvic mets to lung or liver, I have not offered adjuvant RT as the high risk of other mets would negate any benefit of adjuvant RT.

If they develop isolated local relapse, then would consider for salvage.
