Selected existing reports describing dose constraints to the kidney during pancreatic SBRT. SBRT, stereotactic body radiotherapy; SIB, simultaneous integrated boost

Study	Treatment regimen/dose	Dose-volume constraint
Koong et al. [4]	45 Gy/25 fractions + 25 Gy single-fraction SBRT	70% of each kidney <15 Gy
Chang et al. [5]	79% patients with 25 Gy single-fraction SBRT; 21% patients with preceding 45–54 Gy/25–30 fractions	75% of each kidney <5 Gy
Chuong et al. [6]	25–30 Gy/5 fractions, SIB to involved perivascular areas to 35–50 Gy	Kidney mean dose <10 Gy
Su et al. [7]	30–36 Gy/3 fractions	1/3 of kidney volume <15 Gy
Herman et al. [8]	33 Gy/5 fractions	75% of both kidneys <12 Gy
