Ablative proton and IMRT plans for large liver tumors. Shown are axial (A) and sagittal (B) views of a proton plan for a right-sided HCC receiving 75 CGE in 15 fractions to the center of the tumor and 67.5 CGE in 15 fractions to the entire tumor. Another case of fractionated SABR is shown for a massive IHCC that received 75Gy in 25 fractions using IMRT (axial (C) and sagittal (D)) to the center of the tumor, 60Gy to the GTV, and a microscopic dose of 45Gy. Due to the small remnant of normal liver and location of this massive IHCC, the tumor the central SIB and GTV doses had to be reduced from initial goals of 100Gy and 75Gy, respectively.
