From: Stereotactic body radiation therapy for abdominal oligometastases: a biological and clinical review

Whole-liver RT (WLRT) Partial liver RT (PLRT) Stereotactic body radiation RT (SBRT)
≤ 30 Gy, 2 Gy/fraction < 32 Gy, 2-Gy/fraction < 15 Gy in 3 fractions
21 Gy in 7 fractions At least 10% of normal liver spared from radiation < 20 Gy in 6 fractions
   ≥ 700 mL of normal liver receives ≤ 15 Gy
   3 to 5 fractions
