Three-dimensional conformal radiation therapy (3DCRT) has been the standard technique for hepatocellular carcinoma (HCC). Intensity-modulated radiation therapy (IMRT) may be useful to improve target coverage and for normal organ sparing, especially in the setting of unusual-shaped target volumes. Stereotactic body radiation therapy (SBRT) has been used more recently. Individualized prescription doses are commonly used due to variable liver volume irradiated and proximity to luminal gastrointestinal tissues.
