(P16) Hyperfractionated Abdominal Reirradiation for Gastrointestinal Malignancies

We sought to determine the role of abdominal reirradiation for patients presenting with recurrent or new primary gastrointestinal (GI) malignancies, as the role of abdominal reirradiation in this setting remains undefined. At our institution, we have established a hyperfractionated, accelerated reirradiation regimen consisting of 39 Gray (Gy) in 26 twice-daily fractions when reirradiation is desired for pelvic malignancies. We sought to determine the toxicity and efficacy of this reirradiation regimen for tumors in the abdomen.
