Figure 2From: Prognostic factors affecting local control of hepatic tumors treated by stereotactic body radiation therapy Local control per target. Factors associated with better local control: a dose of 45 Gy (p = 0.019), target diameter <50 mm (p = 0.019), a GTV <100 cc (p = 0.063) and a PTV <200 cc (p = 0.014). Back to article page
