4 Fig. 3 (A) Axial, (B) sagittal, and (C) coronal views of radiation plan for patient with bowel perforation 1 month after dabrafenib and trametinib were started. These systemic agents were started 10 days after 20 Gy in 5 fractions using a 4 field technique with 10 MV photons to pelvic bone metastases (shaded red). The V18 Gy and V20 Gy of the large bowel loops (green), small bowel loops (orange), and bowel bag volume (not shown) were 180 and 90 cc, 460 and 230 cc, and 1450 and 750 cc, respectively.
