Key result
Proton-beam radiation therapy resulted in complete remission of a locally recurrent intimal sarcoma of the aortic arch following surgery, as revealed by PET/CT.
Case Report (n=1)
Proton-beam radiation therapy may be an effective treatment for local recurrence of intimal sarcoma of the aortic arch following surgery.
May support proton-beam therapy for recurrent aortic intimal sarcoma; hypothesis-generating and requires prospective validation.
Management of a rare case of intimal sarcoma of the aortic arch is reported, which was diagnosed unexpectedly after total arch replacement for pseudoaneurysm. The prognosis for this condition is poor, with death usually within a few months from diagnosis. The newly developed proton-beam radiation therapy was applied to treat a local recurrence of the sarcoma following surgery. Positron-emission tomography/computed tomography revealed complete remission of the lesion.
